The Debem Fullflow 502 Air Operated Diaphragm Pump is an Italian manufactured AODD pump designed different to other models in the range. Instead of classic ball valves and seats, the suction and discharge manifolds of this Debem pump are fitted with flaps, allowing the passage of solids as large as 45mm in diameter and 600mm in length. This makes these high viscosity AODD pumps ideal for highly solid laden, viscous, stringy, abrasive and shear sensitive mediums as the flap design creates very gentle pumping.

The Fullflow 502 air operated diaphragm pumps are built in glass reinforced Polypropylene with the flap valves available in EPDM, NBR, or AISI316, making it compatible with a wide variety of fluids.

This Debem range of air operated diaphragm pumps are what we like to describe as “Fit and forget” solutions. Thanks to their low maintenance, long service life and patented anti stall protection, the air operated diaphragm pumps can just be left to do their job with little operator intervention.

Features of the Debem Fullflow AODD Pump:

  • Flaps instead of ball valves allow the passing of solids up to 45mm in diameter and 600mm in length.
  • Can dry run without damage, making them unaffected by process stops and pauses in the production line.
  • Self-priming capabilities of up to 3.5m
  • Can handle viscosities up to 20000 cp (depending upon installation)
  • Patented stall protection - If there is a pressure imbalance the pump will continue running without stalling, reducing downtime and time consuming manual intervention.
  • Easily adjustable flow - By amending the air inlet pressure, you can efficiently meet the exact flow requirements of an installation/process.
  • Wide range of uses - Can handle viscous fluids with low moisture content, solids, shear sensitive fluids and aggressive chemicals due to the various diaphragm materials.
  • Low cost to maintain - Long life diaphragms designed for more than 50M cycles and a lot fewer internal wearing parts to maintain compared to equivalent AODD pump models.
  • Fine tuning of motor speed at a constant pressure.
  • Casing in PP and flaps available in EPDM, NBR, or AISI316
  • Actuated via a non-lubricated air system
  • Available with combined or split suction and delivery

Debem Fullflow 502 AODD pumps have a large range of benefits that make them a “fit and forget” solution ideal for many industrial processes.

  • Large solid handling capabilities - Flaps instead of ball valves allow the passing of solids up to 45mm in diameter and 600mm in length.
  • Low cost to maintain - Long life diaphragms designed for more than 50 million cycles and a lot fewer internal wearing parts to maintain compared to equivalent AODD pump models (30 vs a typical 72).
  • Easily adjustable flow - By amending the air inlet pressure, you can efficiently meet the exact flow requirements of an installation/process.
  • Leak-free – It’s seal-less design makes the Fullflow air operated diaphragm pump ideal for handling corrosive fluids that may cause harm, as well as generally being a cleaner solution.
  • Patented stall protection - If there is a pressure imbalance the pump will continue running without stalling, reducing downtime and time consuming manual intervention.
  • Dry run capabilities – Can dry run without damage, making unaffected by pauses in a production line or instances where the operator has left them running
  • Self-priming up to 3.5m – Do not need an additional manual priming device to enable them to draw fluid
  • Versatile - Can handle viscous fluids with low moisture content, solid content, fuels and lubricants and aggressive chemicals due to the various diaphragm materials.
  • 100% pump testing - All models undergo a suction and operation test, as well as a leak check to ensure all are fit for purpose, rather than batch testing.

FAQs

The pump is made up of two chambers. As the air forces the diaphragm to move in to the one chamber it forces the fluid inside into the outlet, whilst the other chamber fills up with fluid drawn from the inlet. As the diaphragm moves back into the opposite chamber, the fluid now in that chamber is forced out and the other chamber begins to fill up.

Thanks to the absence of a mechanical seal that needs cooling and lubricating, AODDs are able to run dry or against a closed discharge indefinitely without causing damage to the pump.

Yes, air operated diaphragm pumps have excellent suction capabilities without need for a manual priming device.

As well as a diaphragm that can run for 50 million cycles before replacement is expected, Debem AODD pumps have a lot fewer internal parts; 30 versus a typical 72 in other models.

AODD pumps are very versatile in their ability to handle aggressive fluids, solids and viscous liquids, and their seal-less design meaning less leaks makes them ideal for hazardous fluids. They are however limited to the fact that they require a compressed air supply to be on site to operate the pump.

Yes. Thanks to the absence of any close fitting or rotating parts, AODD pumps can handle solid content in fluids.

Yes! Whereas with an electric motor you would fit a variable speed drive, with an AODD you can simply adjust the air inlet pressure to control the flow you receive the other end.

Debem AODD pump models are available with additional accessories including air regulator, pulsation dampener to reduce vibrations and provide a smoother flow, trolley, batch meter for preset transfer, pump cycle counter and basket strainer.

Yes - The Debem Food Boxer is constructed of food grade 316 Stainless Steel and PTFE, and the Saniboxer is 3A approved with 360 degree quick emptying system for CIP. The standard Boxer models however are reserved for non-food applications.

To ensure you get the correct Debem spare parts, we need to identify the exact Debem pump model you have. Please advise us of the model number and serial number which can be found on the pump label which is usually on the top of the pump body.

Castle Pumps can supply all Debem pump parts detailed on the spare parts list including diaphragms, balls, ball seats and casings.

All Debem Boxer and Food boxer air operated diaphragm pumps have an integrated patented stall protection. This enables the pump to run under a pressure imbalance to reduce downtime and limit manual operation
