How a positive displacement type diaphragm chemical
Jun 14, 2017· So procuring an accurate pump is crucial. Positive displacement type pumps, and specifically diaphragm chemical metering pumps, are the best for chemical dosing applications. These pumps can be designed to hold up to the corrosive action of nearly any chemical, and remain very accurate for the entire course of their service live.
Consider Positive Displacement Pumps – Chemical Processing
Jul 19, 2012· ROTARY PUMPS. Positive displacement pumps come in many different types. Here, we’ll focus on rotary pumps. The Hydraulic Institute categorizes rotary units in seven primary segments — vane, piston, flexible member, lobe, gear, circumferential piston and screw; this breakdown helps in understanding the various nuances of pump design and operation.
About Positive Displacement Pumps
Controlled-Volume Metering Pumps (CVMP) Controlled-volume metering pumps (also known as metering pumps, proportioning pumps, chemical injection/ feed pumps, or dosing pumps) are reciprocating positive displacement pumps typically used for the injection of chemical additives, proportional blending of multiple components, or metered transfer of a single liquid.

Metering pumps by LEWA – for maximum metering accuracy and reliability. LEWA diaphragm and plunger pumps, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.Discharge pressure: 1200 bar
Metering pumps | LEWA
A practical difference between dynamic and positive displacement pumps is how they operate under closed valve conditions. Positive displacement pumps physically displace fluid, so closing a valve downstream of a positive displacement pump produces a continual pressure build up that can cause mechanical failure of pipeline or pump.
