Product Specification

Air Operated Dual 3 Inch Diaphragm Pump Large Flow Capacity

3 Inch Diaphragm Pump Introduction

Air Driven Double Diaphragm Pump is a new type transferring machinery, is a newest pump at present in China. The power supply is adopt the air compression, to suck all kind of the corrosive liquid completely, such as liquid with granule, high-corrosive liquid, high viscosity, volatile, flammable, poisonous liquid.

3 Inch Diaphragm Pump Parameters

3 Inch 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.

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.
