Product Specification

Powerful Double Acting Diaphragm Pump / Dual Diaphragm Mud Pump 903l/Min

WHY AODD

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

Pneumatic Diaphragm Pump Advantages:

1. Explosion-proof, zero leak, simple operation.
2. Idling capability,Self suction, No complex control.
3. Diversity of material,no rotating parts,applicable to various erosive situations.
4. Diaphragm, ball and ball seat adopt imported materials with longer service life.
5. Modularization of main valve and air motor. No broken, easy to disassemble and repair

OPERATING INSTRUCTIONS

• Always flush the pump with a solvent compatible with the material being pumped if the material being pumped is subject to “setting up” when not in use for a period of time.

• Disconnect the air supply from the pump if it is to be inactive for a few hours.

• The outlet material volume is governed not only by the air supply but also by the material supply available at the inlet. The material supply tubing should not be too small or restrictive. Be sure not to use hose which might collapse.

• When the diaphragm pump is used in a forced -feed (flooded inlet) situation, it is recommended that a “Check Valve” be installed at the air inlet.

• Secure the diaphragm pump legs to a suitable surface to insure against damage by vibration.

Maintenance

• Please refer to the component schematic in the assembly drawings to look up the serial numbers and names of parts and grasp the information of parts and maintenance service pack.
•  
• Some BSK parts are marked as "wearing parts", which can conduce to quick service and downtime reduction.
•  
• Service kits are divided to service two separate diaphragm pump functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SEC -TION is divided further to match typical part MATERIAL OPTIONS.
•  
• Provide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during service disassembly and reassembly.
•  
• Keep good records of service activity and include pump in preven -tive maintenance program.
•  
• Before disassembling, empty captured material in the outlet man -ifold by turning the pump upside down to drain material from the pump.
