Blagdon Air Operated Double Diaphragm Pump.
High Suction, Atex approved Pump for aggressive and hazardous chemicals.
Fully Submersible Pump.
Up to 136 l/min,
1" Air Operated Diaphragm Pump,
The pump chambers are alternately 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.
This pump is available as an Atex approved unit for use in potentially explosive
