Product Brief
Double Diaphragm Pumps are driven by Compressed Air, designed for use in applications requiring large volume transfer in a very short time.
These pumps can transfer contaminated media & are good at cleaning out pits or liquids that can be a mix of several products like oil, water and antifreeze all mixed together.
Handles a wide variety of fluids with high solids content: No close fitting or rotating parts so liquid with high solids content and/or size can be easily pumped.
Self Priming: The pump design (incorporating internal check valves) allows for high suction lift even at dry start-up and with heavier fluids.
Ability to run dry: No close fittings or sliding parts are at risk. The pump can run dry without damage.
Variable flow rate and discharge pressure: Pumps will run at any setting within their operating range simply by adjusting the air inlet pressure and system conditions. One pump can fit a broad spectrum of applications.
Portable/Simple Installation: Pumps transport easily to the application site. Simply connect your air supply line and liquid lines; the pump is ready to perform. There are no complex controls to install and operate.
Dead Head: Because the discharge pressure can never exceed air inlet pressure, the discharge line can be closed with no damage or wear. The pump will simply slow down and stop.
Shear sensitive: The gentle nature and minimal parts contact with the liquid makes these pumps an excellent choice for shear sensitive fluids
Explosion Proof: As pumps are operated by compressed air, therefore, they are intrinsically safe.
Submersible: If external components are compatible–these pumps can be submerged in the liquid by simply running the exhaust line above the liquid level.
Pumping efficiency remains constant: There are no rotors, gears, or pistons, which wear over time and lead to the gradual decline in performance/flow rate.
Diaphragm pumps however do not produce pressure as they have a 1:1 operation & cannot be used with a flow meter. The standard pump configuration is also not suitable for use with flammable media (Gasoline)
All pump Models are designed for use with an Inlet Air Pressure of 20 – 100 PSI (1.40 to 6.89 BAR). Air Inlet on all pump models is threaded ¼” NPT (F)
These pumps are available in a choice of 2 body materials:
a. Aluminum: Aluminum Body pumps come with a Hytrel® (TPEE) Diaphragm. Hytrel® allows these pumps to be used at higher temperatures & imparts much longer life as opposed to pumps with BUNA-N diaphragm. Highly suitable for use with oils. Not recommended for use with abrasive & corrosive liquids.
b. Polypropylene:
Polypropylene body pumps come with a choice of Diaphragms
i. Santoprene® (TPO): Best for use with abrasives, acids, caustics etc.
ii. Teflon® (PTFE): Chemically most inert compound. Suitable for use with highly aggressive liquids such as solvents etc.
