Part I : Key Features that differentiate DEBEM prodcts:
Patented stall-prevention coaxial pneumatic exchanger
Debem pumps use a patented stall-prevention coaxial pneumatic exchanger. This device introduces compressed air to change the equilibrium of the pressure of the diaphragms, assisted by a stall-prevention circuit, that guarantees optimal performance, even in the most critical conditions. The control part (spool) and the power part (exchanger) are both housed inside the pump in a single block, which limits further losses of load when compressed air flows in the pump. The Debem pneumatic exchanger is easy to repair and/or replace. The internal exchanger is built entirely with plastic parts (except for the shaft connecting the two diaphragms), rendering it resistant to corrosive fluids and fumes. The Debem exchanger is pre-lubricated, therefore the supply air for the pump does not require lubrication, quite the opposite, it must be dried and free of impurities, such as oil, dust or condensation. Debem’s pneumatic exchanger (unique in its kind) is built with an extremely low number of parts, making parts replacement and maintenance extremely easy.
Summary of advantages: –
- Low cost of spare parts (single or kit)
- Easy installation
- Self-lubricated system
- No metal parts (only the shaft)
- Stall-prevention system
- Long life of the device: more than 50,000,000 cycles

Amongst the lowest air consumption on the market
The air consumption data (expressed in NL/minute) of Debem’s pumps are real and checked, with certified state of the art instruments and are amongst the lowest available on the market today. Debem’s pumps have been specifically designed to optimise the space on the back of the diaphragms. The volumetric space profiles are developed to guarantee the total dilation of the diaphragms with very small air volumes. Debem’s pumps are designed to optimise the consumption of air, regardless of whether electronic control systems are used. Our competitors sell this option as an accessory but certain misleading advertising would have you believe that this is a production standard. Be suspicious of all companies that claim technical data without having the instruments necessary to determine their veracity. Debem can count on its own new-concept test bench, with state of the art certified instruments, designed to test and certify the parameters of its own products and the efficiency of the pumps, in compliance with the latest applicable standards and in line with the new European project for INDUSTRIA 4.0.
Flow rates
The flow rate that we declare are real. The pumps are tested with a ½ metre of hose in suction as compared to our competitor who test them with the suction manifold immersed directly in the fluid, which is why they declare 10/15 % more than the actual value.
FEM Analysis
The Finite Element Analysis, FEA; (or FEM – Finite Element Method) is a computerised method used to simulate the reaction of a mechanical part to vibrations, heat, fluid flow and other physical interactions. The finite element analysis can be used to predict the risk of failure, speed of wear and correct operation of a product right from the design stage. Even though it is referred to as an analysis, the FEM is an excellent tool to predict the behaviour of a product during its future use.
The most common stress conditions simulated and calculated on the part are:
- Mechanical stress
- Mechanical vibration
- Fatigue
- Movement
- Heat transfer
- Fluid dynamics
- Electrostatic
- Injection molding of plastic materials
All the above precedes and is integrated with our traditional and meticulous quality control, reducing the percentage of supply parts rejects and consequently the possibility of errors during the test stage and, finally, reducing the possibility of premature failures during the use of a Debem product to a minimum. This is another step in our continuous innovation, just a year after the creation of the TestLab, the first IECEx laboratory for certifying air-operated pumps, maintaining our long-term satisfaction standards that Debem’s customers are used to.
