Diaphragm/Positive Displacement Pumps

These pumps are designed for a wide range of metering applications. Select from models for higher pressure metering applications or small size. Ideal for accurate, repeatable metering of chemicals for process control. Small pump options adapt easily to OEM instrument requirements. Pulsatile flow, self-priming to mid levels. These pumps can run dry and in some cases handle low levels of particulates or low viscosity fluids.

 

Variable-Flow Metering Pumps

PM5VC Cased Diaphragm Metering Pump — This cost-effective, low power cased diaphragm metering pump offers flow rates up to 50 mL/min. Select from varying levels of control to meet your application's requirements.
PM10VC Cased Diaphragm Metering Pump — The PM10VC cased diaphragm metering pump offers flow rates up to 100 mL/min. Select from different control options, as well as varying pump materials to fit your chemical compatibility needs.
PM12VC Diaphragm Metering Pump — The PM12VC cased diaphragm metering pump offers higher flow rates than the PM5VC and PM10VC. Select from varying levels of control and flow rates (up to 900 mL/min!).
PM30VC Diaphragm Metering Pump — The PM30VC cased diaphragm metering pump offers all of the chemical compatibility options of the PM10VC with a higher flow rate and greater pressure and suction. Select from different control options, as well as varying pump materials to fit your chemical compatibility needs.
PM60VC Diaphragm Metering Pump — The PM60VC cased diaphragm metering pump offers all of the chemical compatibility options of the PM30VC with a higher flow rate. Select from different control options, as well as varying pump materials to fit your chemical compatibility needs.
PM110 Diaphragm Metering Pump — Rugged diaphragm metering pump with adjustable stroke length adjustment for flow control. Economical, continuous-duty pump. (OEM)
PM150 Diaphragm Metering Pump — Solenoid-driven diaphragm metering pump dual flow control (stroke frequency and stroke length). Chemical resistant, high pressure applications. Select from manual only or manual/remote control models. Integrate easily into pH control system. (OEM)
PB100VC Bellows Metering Pump New! — Compact bellows pump delivers higher flowrates (up to 825 mL/min) than most diaphragm pumps of a similar size. Reciprocal bellows action handles shear-sensitive fluids or agressive particles easily. Select from manual only or manual/remote control modes.

Transfer Pumps

PD200 Diaphragm Transfer Pumps New! — These higher flow pumps are great for transferring liquids. While not as accurate as the metering pumps, the PD200 series more than makes up for that in max flow rates.(OEM)
