Advancing Safety: Rupture Discs for Sanitary Applications

From ipegstl.com

If you’re in the pharmaceutical, biotech or food and beverage industry, you know the importance of protecting your equipment, vessels and systems from overpressurization. In many cases, a rupture disc is the most advantageous of pressure relief devices. It’s precise, leak tight and cost effective.

There are many types of rupture discs, and facilities operating with sanitary and hygienic applications must find rupture discs that are manufactured in accordance with specific codes, standards and approvals. The SANITRX HPX product family from Continental Disc Corporation is one of the most advanced lines of rupture discs available. It has a proven performance in excess of five million cycles, operating up to 95% of burst pressure.

Improve Energy Efficiency with VFD Technology

From ipegstl.com

We turn off the lights when we leave the room. We turn down the A/C when we go on vacation. We turn off the water faucet when we’re not using it. So why are many companies running their pumps at full speed when it’s not needed?

Variable Frequency Drives

Variable frequency drives (VFD) reduce the total energy cost and life cycle cost (LCC) of an industrial pump, fan or compressor. The load profile for any industrial motor varies depending on multiple factors such as weather conditions and facility usage. VFDs are often a good choice for motors that don’t need to constantly run at 100%. They are able to monitor demand and change the motor output to match the load profile, ultimately making the motor more efficient and increasing energy savings. Also, VFDs help reduce the life cycle cost of a motor when it isn’t running at full speed at all times.

Read this article from Yaskawa to learn how to determine if a VFD motor is the right fit for your application. If you’re looking to speak to someone about your specific needs, contact OTP or ask the OTP experts.

Premature Seal Failure in Your Heating Hot Water Pump?

From ipegstl.com

Seal Failure

How is the heating hot water (HHW) pump working in your building? Do the seals seem to wear out far too quickly? Does it always look black when you open it, as though it is burnt on the inside? I have seen these symptoms on a number of occasions—usually in older buildings. What typically happens is that the same parts are put back into the pump, and six months later the seal is leaking again. Our objective at IPEG is to always increase the mean time between failures of your pump, particularly if we are aware there is an ongoing problem. We will look at options, materials of construction, type of pump and other possible factors.

The first thing to do is assess the problem before it is possible to find a solution. If there is premature seal failure, there are always several questions to answer. . .

Clean in Place (CIP) Vs. Clean Out of Place (COP) Sanitary Pumps

From ipegstl.com

There are many levels of “cleanliness” with regard to the sanitary pump market, and the requirements to achieve these levels and certifications vary.  Making the correct decision on which pump technology best fits an application requires some basic information, such as:

  • Fluid (product pumped)
  • Cleaning Process
  • Hygienic Requirements

Wright Flow Technologies offers three pump models to cover various hygienic levels.  These models are: TRA10, TRA20 and Revolution . . .

CONSIDER SEALLESS MAG-DRIVE PUMPS

From ipegstl.com

Although magnetic drive pumps (mag-drive pumps) have been around for almost 70 years, it wasn’t until recently that the general industry lowered their resistance and started embracing the use of mag-drive pumps. Plant managers, engineers, and maintenance supervisors all had the same arguments for why they would not use mag-drive pumps in their plants:

  • Mag-drive pumps are too expensive
  • Catastrophic failure upon “dry-run”
  • Pump and part deliveries are too long

There was no arguing of these points a decade or two ago, but today things have changed. Corporations are looking at additional key driving points than just the initial cost of the pumps. Safety, environment, skill set and reliability are now part of the decision making process.Today the reverse arguments can be made to the above . . .

Proportional Pressure Equals Pressure Management for Municipalities

By Kelly Sulwer, IPEG (a subsidiary of OTP Industrial Solutions)

Pressure control is key for an optimized water distribution system in municipalities. Another term for proportional pressure is demand driven distribution. This means, when installed correctly, proportional pressure control decreases pressure at lower flow demands and increases the pressure at higher flow demands to compensate for pipe friction loss.

Proportional pressure control is especially effective in municipal pump systems since they have long pipe runs and are often oversized for future growth. The pressure requirement is also calculated high, accounting for “fire fight” conditions and using conservative head loss calculations. The end result is an oversized pump with a high pressure set point that will rarely operate in these “worse case” conditions, causing excessive water loss through existing leaks and wasted energy.

To effectively utilize proportional pressure, the percent of friction head of the total required boost pressure must be determined. A consumption pattern or load profile of the water usage is also beneficial to know. This will establish where the pump will operate a majority of the time and help determine how much additional savings can be achieved since there will be less friction head generated at lower flow rates, ultimately lowering the set point.

A few ways to accomplish proportional pressure is remote mounting a pressure sensor or utilizing the built-in logic of the Grundfos MPC controller. Once the controller is programmed with the percent of friction head and preferred adaptation mode (linear or square), it will then utilize the pump’s performance curve and flow estimation software to automatically adjust the set point to compensate for the friction loss seen in the system. This can achieve the following major benefits:

  • Reduction in water leakage from excessive pressure on pipes
  • Reduction in maintenance cost on piping
  • Reduction in energy consumption by utilizing the VFDs more effectively towards the system’s demands
  • Reduction in the amount of pipe burst in the distribution network

The ability to control pressure effectively can lower leakage losses and save overall operating costs. To ensure a properly sized system, contact IPEG to help select the correct size, type and number of pumps best suited for your system’s needs.

NET POSITIVE SUCTION HEAD (NPSH) 101

By Dan R. Benjamin

Anyone who has studied a pump performance curve has seen several components on the graph below. There is usually a vertical axis that depicts pressures and a horizontal axis that depicts flow rates. Additional components include efficiency, horsepower and impeller diameters. There may also be a curve labeled NPSH or NPSHr.

pump performance curb

NPSH = Net Positive Suction Head
NPSHr = required
NPSHa = available

Every pump installation has a certain amount of NPSHa and every pump has a certain amount of NPSHr at each given performance point. Simply put, pumps need positive pressure on the suction side in order to “push” the liquid being pumped into the suction of the pump. That push comes from the sum of all the positive influences on the liquid to be pumped at the source. These positive influences include atmospheric pressure and the actual height of the liquid above the pump suction. Additional factors to consider include both temperature and characteristics of the liquid.

NPSH PROBLEMS

Pump performance problems can occur if NPSHa is not properly considered when selecting a pump for a given application. The NPSHa has to be calculated and compared to the NPSHr, as supplied by the pump manufacturer.

If there is not enough NPSHa, numerically expressed as a number greater than the NPSHr, you can expect the pump to cavitate which shortens its useful life and limits its performance. If the pump you have selected cannot be reconsidered, there are several solutions. The feasibility of these solutions can only be considered when evaluating specific installations.

POSSIBLE SOLUTIONS

  • Raise the liquid level on the suction side which increases the vertical height
  • Lower the temperature of the liquid being pumped (vapor pressure)
  • Physically lower the pump
  • Physically raise the tank on the suction side
  • Increase the diameter of the suction piping
