How do Diaphragm Pumps Work?

Diaphragm pumps work by flexing the diaphragm out of the displacement chamber.

When the diaphragm moves out, the volume of the pump chamber increases and causes the pressure within the chamber to decrease and draw in fluid.

Advantages of a Diaphragm Metering Pump

  • Low cost of ownership

    Well maintained diaphragm metering pumps cost you less to operate over time

  • Energy efficient

    Diaphragm pumps use more motor torque on the forward (power) stroke, but far less on the back stroke

  • High pressure capabilities

    Overcoming line pressure is easier with properly sized diaphragm metering pumps

  • Exclusive longer lasting diaphragm

    Blue-White's patented DiaFlex® diaphragms last the life of the pump
