Small 1 Inch Air Diaphragm Pump Air Operated Pneumatic Pump Non Leakage


The Air Operated Diaphragm (AOD) Pump is a positive displacement pump powered by compressed air. AOD pumps offer a sanitary, energy-efficient way to transfer product. They are ideal for viscous products, products that require no or low shear pumping, or products that contain solids or are nearly solid (it is a gentle beast). It is popular in the brewing industry as a product transfer pump; although there is often some confusion as to how they work and why a brewer would want one.

Air diaphragm pump(also know as a Membrane pump, air operated double diaphragm pump(AOOD) or pneumatic diaphragm pump)that uses a combination of the reciprocating action of a rubber,thermoplastic or teflondiaphragm and suitable valves either side of the diaphragm (check valve,butterfly valves,flap valves,or any other form of shut-off valves) to pump a fluid.

Main Advantages
1, Due to the use of air power, the flow automatically changed according to export resistance. Which is suitable for high viscosity fluid.
2, In inflammable and explosive environment, the pump is reliable and low cost, won't produce spark and not overheat,
3, The pump volume is small, easy to move, no foundation needed, convenient installation and economy. Can be used as mobile conveying pump.
4, Where there are dangers, corrosive materials processing, diaphragm pump can be separated completely with outside.
5, The pump shearing force is low, physical effect to medium is small, can be used for conveying unstable chemistry fluid.

  • 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.


AOD pumps can transfer pressurized product (such as carbonated beverages) at low pressure and low speeds. This is extremely handy when the product is fizzy or frothy. It is also quite gentle for your more precious products. The self-priming pneumatic motor creates an oil-free design that does not require any lubrication. The risk of cavitation is removed and it can be deadheaded with no damage.

A couple interesting features of the AOD pump include:

  • Very specific control of flow
  • Can run at low speeds
  • Can run dry
  • CIPable
  • Can transfer mostly solid products or products containing solids
  • Low shear effects (Solids stay solid!)
