Double Diaphragm Pumps are designed
for use in applications requiring large
volume transfer in a short time
Driven by compressed air, these can
transfer contaminated media & are very
useful for cleaning out pits with mixed
liquids such as oil, water etc.
Handle a wide variety of fluids with solid
content as there are no close fitting or
rotating parts
Self Priming
Pump is designed for high suction lift
even at dry start up & also with heavier
fluids
Ability to run dry, as there are no close
fitting or sliding parts
Portable/Simple Installation
Simply connect air supply line & liquid
line; pump is ready to perform
Explosion Proof
Safe pumps since they are operated by
compressed air
Pumping Efficiency Remains Constant
No rotors, gears or pistons that
wear over time, hence no decline in
performance
All pump models are designed for use
with an inlet air pressure of 20-100 PSI
Air inlet threaded 1/4" NPT (F)
Pumps are available in a choice of 2
materials
- Aluminium body with a Hytrel*
diaphragm. These can be used for all
high temperature applications
- Polypropylene - body with
- Santoprene Diaphragm - for use
with abrasives, acids, caustic etc.
- Teflon (PTFE) Diaphragm - for use
with fluids such as solvents

Versatile Fluid HandlingThese pumps efficiently manage a wide spectrum of fluids, including chemicals, abrasive slurries, and viscous liquids. Their ability to handle solids up to 6 mm and adjust speed by controlling air supply makes them ideal for challenging industrial processes. Multiple port sizes and connection types ensure compatibility with existing systems.
Robust Construction, Flexible InstallationManufactured from durable materials like aluminium, polypropylene, and stainless steel, these pumps are designed to endure harsh environments. Users can choose diaphragm materials like PTFE or Santoprene to match fluid properties. Installation is straightforward on floors, panels, or skids, enabling seamless integration into industrial setups.
Reliable Operation & Maintenance SimplicityOperating purely on compressed air, these pumps remove reliance on electricity and electric motors. Their self-priming and dry running capabilities minimize downtime and maintenance. The adjustable air consumption and low noise level contribute to efficient and comfortable working environments in industrial locations.
FAQ's of Air Operated Double Diaphragm Pumps:
Q: How does an Air Operated Double Diaphragm Pump work without an electric motor?
A: This pump is powered solely by compressed air supplied from an external source. Air moves between chambers, flexing the diaphragms and enabling fluid transfer, eliminating the need for electricity and making the pump suitable for hazardous or remote industrial environments.
Q: What types of fluids can these pumps handle effectively?
A: These pumps are capable of handling a broad range of fluids such as chemicals, acids, solvents, abrasive slurries, and viscous liquids. Their ability to manage solids up to 6 mm also allows efficient processing of mixtures and particulates in various industrial applications.
Q: When should I choose different diaphragm materials for these pumps?
A: Selecting the diaphragm material depends on the chemical compatibility and temperature range of your application. PTFE is best for highly aggressive chemicals, while Santoprene and Neoprene suit general-purpose duties. Buna-N works well with oils and fuels. Consider the fluid's properties when making your choice.
Q: Where can these pumps be installed for optimal performance?
A: These pumps can be mounted on floors, panels, or skids depending on your industrial setup and space constraints. Their compact dimensions and flexible port connections (BSP/NPT threaded or flanged) facilitate easy integration into new or existing systems.
Q: How do I adjust the flow rate and speed of the pump during operation?
A: Flow rate and speed can be accurately controlled by varying the air pressure supplied to the pump. Using an air regulator allows the user to fine-tune performance for specific processes and accommodate changing fluid transfer demands.
Q: What are the benefits of using these pumps in industrial environments?
A: Air operated double diaphragm pumps offer self-priming capabilities, dry running protection, and the ability to handle viscous or abrasive fluids. Their air-driven mechanism removes electrical risks, provides variable speed control, and ensures quieter, low-maintenance operation, optimizing productivity and safety.
