Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outletThe volume of flow is determined by several factors including: The number and size of the pump chambers, cam offset, operating pressure, fluid viscosityMotorType:12VDCpermanentmagnet,totallyenclosed,non-ventilatedAmps8.0AMaxCertificationCE,ISO9001:2008,RoHSFlowRate5.5LPM/1.5GPMPressure80psi/6.9barPortdimension3/8"FNPTDiaphragmSantoprenevalveVitonorEPDMDutyCycleIntermittent
