Common Problems with Pumps and Compressors

Companies in many industries rely on pumps and compressors to safely and efficiently transport fluids throughout their facilities. These systems appear in manufacturing sectors ranging from:

  • Pharmaceutical
  • Food and beverage processing
  • Petrochemical
  • Power generation

The size and output of a pump or a compressor varies depending on the fluid that it handles as well as the amount of power required to move the media. For this reason, pumps and compressors range in size from small handheld devices to large industrial equipment. However, a few commonalities exist across all pumps that make diagnosing problems in these systems easier for facility managers.

In this post, we explore a few of the most prevalent issues encountered by pump and compressor owners, and we describe some strategies on how to overcome them.

Problems That Can Arise

Pumps are very loud when they operate, which means that they’re commonly housed in separate rooms within the facility. Pump rooms are often small in size, meaning that very little space exists between valves, fittings, and piping. This creates tight operating conditions for maintenance personnel, and it also means that any problem with the equipment can have cascading effects.

In multiple pump systems that share a common header, the sudden cessation of one pump can create problems in other parts of the system. This can be compounded by compressors, which generate pressure pulsation that can create excessive wear on valves, fittings, and piping if not properly handled.

Finding a Solution

Many facility owners mitigate these risks by installing axial flow check valves. These valves ensure that fluids flow in only one direction, and tare designed to eliminate back flow.

Axial check valves operate via a disc and spring mechanism that prohibits fluid from reversing its flow direction. When pressure builds up on one side of the disc controlled spring , the disc opens, allowing fluid to flow through the valve. However, when there is not enough pressure on the other side of the spring, the valve stays closed, preventing back flow.

These spring mechanisms reduce the risk of water hammering, which increases the valve’s longevity. Valves of this type also occupy less space than manual valves and other check valves, making them easier to install in crowded environments. Axial check valves can be installed vertically or horizontally, which allows them to be used in a number of different applications.

3 Effective Methods to Prevent Check Valve Failure

Increasing the Life Span of a Check Valve

Check valves are an important component in piping used to transport fluids. A properly functioning check valve allows liquid to flow in one direction and prevents reverse flow in the opposite direction. Proper installation and preventative valve maintenance are necessary to keep check valves in peak condition.

During installation, it is essential to consider the flow capacity. Proper valve size is necessary to prevent performance issues. Oversizing can lead to vibration damage, shortening the life span of the check valve.  However, if you complete routine maintenance on a correctly sized check valve, you can prevent leakage and premature failure.

Method 1: Taking Preventative Measures

The first step in valve maintenance is making sure the pipeline and valves are clean and free of debris. Filters are a simple and effective way to prevent debris from entering the system. If debris does get in the piping, flush the pipes to minimize buildup and remove settled debris. It’s essential to establish a consistent maintenance schedule on all check valves.

Method 2: Choosing the Right Check Valve

This method can improve the function and longevity of the system. Choose a properly sized check valve based on vertical or horizontal orientation, type of media, and the normally expected flow condition specific to the application—not the size of the pipeline. Incorrectly sized valves can cost more, reduce flow velocity, and cause malfunctions such as water hammer. For optimal performance, the valves must be installed correctly and used as directed in the manufacturer’s instructions.

Method 3: Upkeep to Maintain Tight Shut Off

Sometimes a system may need proper routine inspections to maintain tight shutoff and prevent premature check valve failure. You can keep a tight shut off by removing any foreign matter.If flushing hasn’t helped, remove and completely disassemble the valve. Inspect it for scratches on the valve seat and the disc. Then, wash all parts in clean fluid that is used in the system. As you reassemble the valve, inspect the housing and trim parts for any corrosion or erosion. Replace the valve if there is corrosion or excessive roughness due to erosion.

Supporting Your Check Valve Needs

Appropriate check valve choice and regular inspections are key to preventing premature failure in any application. DFT® has been manufacturing check valves and solving any issues for over 70 years.  Contact us today to learn more about how DFT can support your check valve needs.

DFT® Makes Commitment to Sustainable Energy with Solar Initiative

Most manufacturing operations take a substantial amount of power to operate, often making it difficult for industry stakeholders to effectively reduce their carbon footprint. However, with improvements in solar panel technology and power storage, it is now possible for industrial facilities to significantly reduce their impact on the environment. Solar also makes more financial sense for industrial applications, as most factories, warehouses, and other facilities have large, flat roofs that are ideal for these panels.

Solar power is considered one of the greenest renewable energy sources, surpassing other options like natural gas, because its energy produces zero emissions at every stage. It has also surpassed wind to become one of the most affordable end-to-end sources of renewable energy.

DFT® Goes Solar

At DFT® Valves, one of our core company values is a commitment to sustainable operation. In pursuit of this, we have completed the installation of roof panels on our facility that generate approximately 63% of our annual electricity requirements, or 304 kilowatts per minute while the sun is shining.

Since most of our electricity consumption occurs during the day while we are in full production, we can largely offset the power requirements of the production processes. At night, when our power requirements are minimal, we can still use power from the local grid.

We’re also able to sell power back to PECO seven days a week, which provides significant savings that will help us break even on the project in the next few years. In addition, about 33% of the cost was covered through a grant from the state of Pennsylvania, and we expect to receive additional state and federal tax incentives as well. This means we won’t have to pass on any related upfront or ongoing costs to customers. We’ll also contribute to sustainable energy use in the community by assisting PECO in providing power to more than 100 homes in the surrounding area.

Your Sustainable Valve Provider

DFT® Valves provides check valves and control valves for use in a range of applications across a broad array of industries. It is our mission to provide solutions that help you avoid critical valve failures that will negatively impact your operation. The addition of solar panels to power operations shrinks both the company’s and our customers’ carbon footprints.

Safety Protocols in the Workplace

For any manufacturing business, safety is of the utmost concern. A company’s workers are its most valuable asset, and toprotect that asset, it’s critical to maintain a working environment that prioritizes health and safety. At DFT, employee health and safety is placed above all else. We are committed to maintaining a safe and hazard-free environment by complying with the Occupational Safety and Health Administration’s (OSHA) workplace requirements to create a safe workplace for our employees.

We have OSHA-30 – certified supervisor and manager that work tirelessly to ensure that we are complying with all OSHA regulations throughout the company. Our diligent commitment to OSHA standards, combined with our

internal safety best practices, ensures that we meet or exceed the occupational health and safety standards set forth for our industry.

There are many ways in which DFT practices safety in the workplace. For example, DFT’s seven-member safety committee encourages safety awareness among employees, incentivizes their participation in our safety program, and educates them about safety best practices. We also provide thorough training to our employees from certified forklift and overhead crane operators to ensure that our own equipment operators are aware of current best practices.

We even have an AED/CPR-trained emergency response team comprising nine individuals who are equipped to handle any medical emergencies that may arise at work. Our team also understands the importance of recognizing our employees’ comfort and safety levels; thus, we never require a DFT employee to perform a task or job that they are uncomfortable with or that makes them feel unsafe.  Furthermore, to maximize our safety knowledge, we work with Gallagher Bassett to provide outside training, education, and risk control assessments to help minimize equipment, personnel, and product losses.

The actions mentioned above are just some of the safety practices that DFT has integrated into our day-to-day operations. Below, we dive into some of our key strategies for boosting safety in the workplace.

Promoting Health and Safety in the Workplace

Creating a safer work environment requires a commitment from all levels of a company’s workforce. We try to emphasize the importance of safe work practices among our employees by engaging them directly from the ground up. To accomplish this goal, we have created a company safety committee where representatives from our labor pool work with members of our management team to identify hazards and unsafe work practices, prevent accidents by removing any known obstacles, and evaluate the company’s ongoing efforts to achieve and accident-and-injury-free workplace.

How the Shale Revolution is Impacting American Manufacturers

When a new economical source of natural gas was created by pairing horizontal shale drilling with refined hydraulic fracturing techniques, or slick-water fracturing (known as “fracking”), the shale revolution began.

With approximately 70% of chemical products’ final production costs going toward raw materials, such as ethylene or propylene, the petrochemical industry faces very tight margins and is significantly impacted by raw material and shipping costs.

Providing manufacturers with an unprecedented amount of low-cost natural gas, the shale revolution repositioned the United States’ role in the worldwide chemical marketplace and opened up many new manufacturing opportunities.

Shale-Revolution-AmericaRELATED: How the Shale Revolution is Impacting Manufacturing in America

The Rise of Chemical Processing Plants in America

Currently, the United States is one of only three countries capable of extruding natural gas from shale rocks on a commercial scale and has become a world leader in the chemical processing and export markets.

In 2000, natural gas provided by shale accounted for just 1% of all U.S. natural gas production; by 2010, it accounted for over 20%. And the shale revolution doesn’t appear to be slowing down anytime soon. The Energy Information Administration predicts shale gas will make up 46% of America’s gas production by 2035. BP’s Energy Outlook report is even more optimistic, forecasting that “shale gas will account for three-quarters of total U.S. gas production in 2035, almost 20% of global output.”

Thanks to this rapid market growth, there’s been a surge in investments in ethane-consuming petrochemical plants and export facilities since 2012, according to the U.S. Energy Information Administration (EIA). Dow Chemical, for instance, has made a $6-billion investment to expand its Gulf Coast facilities and construct a new cracker facility.

Which States Have Experienced the Surge in Chemical Processors?

At DFT® Inc., we’ve had the chance to be a part of various developing chemical processor plant projects. Our team is often called upon to help petrochemical processors with check-valve solutions to prevent leaks, control turbulence, prevent reverse flow of liquids, protect valuable equipment, and provide tight shutoff. In particular, we’ve seen significant growth in chemical processing plants in the following states:

  • Texas: Still the leader in both oil and gas production, Texas is expecting to see more than 100 petrochemical projects completed over the next decade. And with the newly discovered Wolfcamp shale deposit, which is believed to contain three times more natural gas and petroleum than the Bakken Formation, Texas is sure to see increasing investments for years to come.
  • North Dakota: In North Dakota, the Bakken Formation and Williston Basin have transformed the state’s economy, and North Dakota is now the second leading shale gas producer in the country. This, in turn, has led to several major investments; several new fertilizer plants, for instance, have been constructed.
  • Oklahoma: Centrally located at the intersection of many of the nation’s pipelines, Oklahoma has also seen a major boom in petrochemical plant investments over the last several years. In fact, “oil and gas activity accounts for more than half the fixed investment ($20.3 billion) in Oklahoma,” according to a report by the State Chamber of Oklahoma Research Foundation.
  • Pennsylvania: Extending from Upstate New York through Pennsylvania, West Virginia, and parts of Ohio, the Marcellus Shale is proving to be a huge source of revenue for Pennsylvania, with many new facilities being built and the Sunoco Logistics Partners’ Marcus Hook Terminal serving as a major ethane export hub. Just in the past few weeks, in fact, Shell Chemicals invested in a $6-billion ethane cracker plant in Western Pennsylvania.
  • Ohio: Located in Ohio, the Utica shale play is positioned to be one of the next major natural oil and gas reservoirs. The most oil-rich area, known as the Point Pleasant formation, is located in Eastern Ohio. Many experts compare it to the lucrative Eagle Ford Shale, which created thousands of jobs, generated $2.9 billion in total economic output, and created over $47 million in local government revenues. And because Utica underlies Marcellus, many resources and necessary infrastructure are already in place.
  • West Virginia: The Utica and Marcellus shale boom has also helped West Virginia; from 2002 to 2014, annual natural gas production grew from less than 100 billion cubic feet to more than 1 trillion cubic feet, with new plants emerging regularly. The Rogersville Shale, also, located in Southern West Virginia, has so far produced modest results but could very well provide significant profits over time.

How Ethylene is Affecting the Manufacturing Industry

Ethylene — a colorless, odorless gas created by “cracking” ethane from natural gas liquids (NGLs) — is an extremely versatile substance, used in everything from plastics to pharmaceuticals. As a major raw-material building block, ethylene is one of the most important chemicals in American manufacturing.

Less than a decade ago, the United States was shipping much of its bulk chemicals, like ethylene, overseas. Now, thanks to new innovative manufacturing trends and the abundance of low-cost natural gas, petrochemical manufacturers across the country are greatly expanding their cracking capacities.

In fact, according to the American Chemistry Council, U.S. chemical companies have announced investment projects totaling over $145 billion. In addition to crackers, these investments are going toward other facilities, such as plants in which various chemicals and plastics are made for export. The United States’ increased ethane production has also led to increased ethane export.

This resurgence is bolstering the U.S. manufacturing sector at large, as plant capacities increase and more and more skilled manufacturing jobs become available.
