1. The diaphragm operates in a balanced condition during the discharge stroke which allows the pump to be operated at discharge heads 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 pressurizing and exhausting of the diaphragm chamber is performed by an externally mounted pilot operated four way spool type air distribution valve When the spool shifts to one end of the valve body inlet pressure is applied to one diaphragm chamber and the other diaphragm chamber exhausts When the spool shifts to the opposite end of the valve body the pressure to the chambers s20mdl1sm REV0509 is reversed The air distribution valve spool is moved by a internal pilot valve which alternately pressurizes one end of the air distribution valve spool while exhausting the other end The pilot valve is shifted at each end of the diaphragm stroke when a actuator plunger is contacted by the diaphragm plate This actuator plunger then pushes the end of the pilot valve spool into position to activate the air distribution valve The chambers are connected with manifolds with a suction and discharge check valve for each chamber maintaining flow in one direction through the pump INSTALLATION AND START UP Locate the pump as c2. 13 13 16 26 5 16 Sound Dampening 15 1 8 Metal Muffler 1411 16 Model S20 Metallic Page 4 24 3 4 Stainless Steel Mesh Muffler 15 1 8 Both Suction And Discharge Ports Are Available With 2 BSP Connection Metric Dimensions S20 Metallic Dimensions in Millimeters Dimensional Tolerance 3mm 148mm Discharge Port 2 NPT FRONT VIEW SIDE VIEW Both Suction and Discharge Ports Are Available With 2 BSP Tapered Connection J Suction Port 2 NPT 60mm Integral Muffler 1 NPT Exhaust Port For Optional Muffler Styles or Piping Exhaust Air In Submerged Applications 128mm i ira Ea 229mm T s LA i 3 4 NPT Mesh Muffler B OTTO M VI EW Sound Dampening 320 320 84 84 Muffler s20mdl1sm REV0509 Model S20 Metallic Page 5 PRINCIPLE OF PUMP OPERATION This ball type check valve pump is powered by compressed air and is a 1 1 ratio design The inner side of one diaphragm chamber is alternately pressurized while simultaneously exhausting the other inner chamber This causes the diaphragms which are connected by a common rod secured by plates to the centers of the diaphragms to move in a reciprocating action As one diaphragm performs the 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
