About Air Driven Double Diaphragm Pump

If you're looking for a single pump that can be used in a wide variety of applications, you want an air-operated double diaphragm (AODD) pump. JBSL provides the most complete line of AODD pumps available from one source. No other manufacturer offers more AODD pumps – or more size and flow options – that meet every sanitary standard, including FDA, USDA, 3A and EHEDG.

Product Features

1Ceramic material for main valve and reversing valve ensures longer life, more stability and working in dirty compressed air ( most occasions, air filter become option).
2Without ice with the muffler. Innovative design with the exhaust space of the pump, some of muffler inside, this makes the air outlet smooth.)
3Outward parts of the pump are all die casted aluminum and special environment-protected painting, makes the pump with elegant appearance.
4Large flow capacity. Innovative design of chamber maximizes the flow capacity. Seamless adjustment with inlet valve, or even close the valve, without damaging the pump.
5Low consumption compressed air. Innovative design of the air flow system, minimizes the usage of compressed air to achieve maximum performance.
6Light and small size, movable.
7Modularization of main valve and air motor. No broken, easy to disassemble and repair.
8Optimized design greatly reduces overall component number of pump. Significantly improve performance, help for maintenance.
9For power variety, pneumatic pump’s flow capacity normally lowers than electric pump, but BSK pump is workable in series at certain conditions. This can largely satisfy customer request.
10Innovated design of sealing structure and material, totally solve the leakage inside or outside.
11BSK pump can be started with low air press ( only 1.5 KG air press can start BSK pump).

1.5" Flow diagram


  • 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.


  • 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.
