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 hrough the inlet,
through the various valve chamber check valves to the outlet he volume of flow is determined by several
factors including: the number and size of the pump chambers,cam offset, operating pressure, fluid viscosity.
