Air operated double diaphragm pumps
Debem’s air operated double diaphragm pumps are ideal for pumping liquids with high apparent viscosity, even if containing suspended solids. The stall-prevention circuit guarantees a safe operation, without requiring lubricated air. These pumps have achieved unprecedented levels of versatility due to their self-priming capacity with a considerable suction head, the ability to fine-tune the speed without losses of pressure as well as the possibility of dry-running without suffering damage. The vast range of construction materials allows us to select the best chemical compatibility with the fluid and/or the environment, without neglecting the operating temperature range. The construction principle of the air operated double diaphragm pumps makes them ideally suited for demanding applications or potentially explosive atmospheres (ATEX – IECEx certification).
The cubic design and limited size, make them ideally suited to be installed directly on industrial equipment for the chemical sector, to pump ink and paint, on printing machines, in oil circulation and in applications where moderate quantities of fluid must be pumped in small spaces. The CUBIC range of double diaphragm pumps includes the MIDGETBOX air pump which is currently the smallest and highest performing pump on the market for the chemical sector.
The pumps of the DEBEM FDA Boxer line adhere to the requirements established by the FDA regulations and represent an ideal solution for the food and health industry.
The air-operated double diaphragm pumps of the DEBEM REMOTE CONTROL range have been designed and built to offer our customers greater control for dosing and measuring applications and wherever there is the need to drive the pump with electric/electronic devices, to allow for the full-automation of the process.
Its horizontal fluid circuit, unique of its kind, differentiates it from the complex alternatives of the competition and facilitates the flow of the fluids and solids contained in them. In fact, the pump is equipped with clapet valves that allow the passage of fluids of various viscosities with solid parts in suspension up to 600 mm in length (configurable on request for even greater lengths) and with a diameter of up to 45 mm. The inspection and cleaning of the valves is quick and easy to carry out even by unqualified personnel.

Cubic and Boxer air-operated double diaphragm pumps
The air operated double diaphragm pumps and volumetric pumps are sturdy and powerful, self-priming (dry negative vacuum) also in demanding conditions and they can transfer liquids with high viscosity, even with suspended solids. The BOXER and CUBIC series both feature a special pneumatic exchanger coaxial to the shaft and without any external component. It is a unique piece of engineering that is highly-resistant to the formation of ice and only found on our pumps. All the air operated double diaphragm pumps of these two series have been tested to guarantee maximum safety in demanding environments (that is in the presence of particularly aggressive and viscous fluids), they are suitable for dry-operation without being damaged, don’t require lubricated air and are self-priming. Their components are easy to replace and the maintenance can easily be performed by non-qualified personnel. They are available in the following versions: POLYPROPYLENE, PVDF / ECTFE, Aluminium and AISI 316 L stainless steel.
