Performance MHDF1/MHDF25 MODEL HDF1 Performance Curve SUCTION/DISCHARGE PORT SIZE Performance based on the following: elastomer fitted pump, flooded suction, AIR CONSUMPTION • MHDF1: 1” (25.4mm) NPT(F) water at ambient temperature. Average displacement per pump stroke: .10 Gallons (.38 Liters). SCFM (M 3 /hr) The use of other materials and varying hydraulic conditions may result in deviations in excess of 5%.
Principle of Pump Operation Air-Operated Double Diaphragm (AODD) pumps are powered by compressed air or nitrogen. The main directional (air) control valve distributes ① compressed air to an air chamber, exerting uniform pressure over the inner surface of the diaphragm .
Recommended Installation Guide Available Accessories: 1. Surge Suppressor In the event of a diaphragm rupture, pumped fluid can enter the air center section 2. Filter/Regulator of the pump and exit through the air exhaust port. When pumping hazardous fluids, it is recommended to pump the exhaust air to a safe location. 3.
Troubleshooting Guide Symptom: Potential Cause(s): Recommendation(s): Pump Cycles Once Deadhead (system pressure meets or exceeds air Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero flow. supply pressure). (Does not apply to high pressure 2:1 units). Air valve or intermediate gaskets installed incorrectly.
