SV653 Diaphragm Isolated Dispensing Pump


The SV653 series dispensing pump is a solenoid operated high purity piston driven pump that delivers a wide range of fluids with high precision. By combining the easily adjustable stroke of the pump with variable cycle rates, users have complete control of the volume and rate of dispense for specific applications. A flexible diaphragm isolates the liquid from any metallic parts. Wetted parts are Polypropylene and PKM or EPDM, making this series suitable to handle a wide range of fluids.
