Web Site www blagdonpump com E Mail sales blagdonpump com HG CF 921 Rev L 28 07 05 Page 4 PRINCIPLE OF PUMP OPERATION This ball valve type diaphragm pump is powered by compressed air and is a 1 1 ratio design The inner side of one diaphragm chamber is alternately pressurised while simultaneously exhausting the other inner chamber This causes the diaphragms which are connected by a common shaft secured by plates to the centres of the diaphragms to move in a reciprocating action As one diaphragm performs a discharge stroke the other diaphragm is pulled to perform the suction stroke in the opposite chamber Air pressure is applied over the entire inner surface of the diaphragm while liquid is discharged from the opposite side of the diaphragm The diaphragm operates in a balanced condition during the discharge stroke which allows the pump to be operated at discharge heads of over 200 feet 61 meters of water For maximum diaphragm life keep the pump as close to the liquid being pumped as possible Positive suction head in excess of 10 feet of liquid 3 048 meters may require a back pressure regulating device to maximize diaphragm life Alternate pressurising and exhausting of the diaphragm chamber is performed by an externally mounted pilot operated 2 way type distribution valve When the spool shifts to one end of the valve block body inlet pressure is applied to one chamber and the other diaphragm chamber
