Environmental Protection Diaphragm Mud Pump / Small Air Operated Submersible Pump

Environmental Protection Diaphragm Mud Pump / Small Air Operated Submersible Pump

WHY AODD Diaphragm Mud Pump

Air-operated double diaphragm (AODD) pumps offer a number of advantages that make them perfect for an almost endless variety of uses. AODD pumps:

• Can easily and efficiently handle anything from water to 90% solids
• Offer the ability to vary flow and discharge pressure up to 125 psi with a simple adjustment of the air supply
• Enable one pump to be used for numerous applications, eliminating the need for expensive motor drives and critical sizing calculations
• Can pass even large, shear-sensitive solids without degradation or heat buildup transferred to pumped medium
• Are able to run dry without damage to pump
• Can operate "on demand systems" without expensive pressure relief and bypass accessories
• Will not froth or separate medium
• Are capable of pumping as slow as one gallon per minute

Working Principle

In the pump two symmetrical working chamber each equipped with a diaphragm, the center link will be integrated into one. Compressed air from the pump inlet into the valve, through the valve body to introduce compressed air into one of the chamber to promote movement of the diaphragm chamber, while the other chamber gas emissions. Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction so that the two diaphragms move back and forth in unison.
