Metering pumps deliver a precise, though adjustable, amount of fluid into a chemical-feed system. They are designed for accuracy, so flow rates tend to be low for many applications and are typically measured in gallons (or liters) per hour instead of per minute. With an emphasis on controlled flow, it is important that pulsations produced […]
Dynamatic eddy current drives offer many advantages over VFDs in applications requiring pumps to match a varying demand for flow or pressure. Download Dynamatic’s Municipal Application Guide infographic.

Steps all flare gas recovery operators should take to avoid unplanned downtime Safe and efficient operation of liquid ring compressors in flare gas recovery applications depends on careful consideration of process factors in order to ensure trouble-free operation. Facility operators, including process engineers, specifiers, purchasers and maintenance specialists, along with their equipment suppliers should collaborate […]
For a valve rebuilder, it just doesn’t get any better than this. EGC Enterprises knows more about flexible graphite than most other companies in the world because they engineer and manufacture high-tech, high-temperature, high-pressure fluid sealing products. Founded in 1978, EGC has a long history of innovation and customer-based solutions. EGC engineers are recognized worldwide […]
Whether processing pharmaceuticals, treating drinking water, or feeding a boiler in a power plant, pumps are among the most extensively used industrial products. Not only do pumps come “in all shapes and sizes,” there are different pumping technologies available to meet widespread applications. This paper examines a specific technology, the seal-less design of a positive […]
When selecting a submersible pump model, the question may arise of what type of impeller is best for the application. Many manufacturers offer a variety of impeller designs to fit differing installations, and choosing the right impeller for the job is an often-overlooked aspect of station design. For non-clog submersible pumps, there are typically closed […]

The AVANT™ features an FM approved design, premium IE3 motors, and closed-loop cooling jackets. They have been designed to operate over a wide range of conditions; with multiple options for […]
Introduction There are some things you just can’t avoid: death, taxes, and a pump’s common operational pain points- leaks, dry run, solids handling, cavitation-causing NPSH imbalance operation off the BEP, and incomplete performance curves that are inherent in chemical-transfer applications. It was in the 1980s that the first viable pump technology was created that could […]
Author: Mark Savage, FSA Member As operators of pumping equipment become more focused on the safety, reliability and environmental impact resulting from shaft seal leakage, dual mechanical seals have become more prevalent in the industry. A dual mechanical seal offers a second (outer) seal to contain the pumped fluid by creating a cavity or chamber […]
Almost all centrifugal and rotary pumps require a sealing system to provide sealing integrity of the drive shafts carrying the impellers and protect against pumped fluid leakage and the environment outside of the wetted areas. These sealing systems range from traditional braided materials packed around the shaft to complex mechanical seal systems used in many […]
