Blagdon B25 PTFE Diaphragm Pump

Up to 136 l/min, 

1" Air Operated Diaphragm Pump,

PTFE Construction.

 

The pump chambers are alternatively filled and emptied by drawing fluid in through a common (suction) inlet, and out through a common (discharge) outlet. The diaphragms in each chamber are linked by a common shaft, so that they move backwards and forwards in unison. Compressed air is directed by the air valve alternatively, behind each diaphragm, to power discharge strokes. Pump speed, fluid output and pressure (or head) is controlled by increasing or decreasing the flow of compressed air to the pump.

The delivery can be simply controlled by restricting the flow of the air to the air inlet.
