Boxer diaphragm pumps are characterized by exceptional performance, power and strength, making them ideal for pumping liquids with high apparent viscosity even if containing suspended solids.
The stall-prevention pneumatic system assures a safe pump running and it does not need lubricated air.
Self-priming dry capacity even with considerable suction head, fine tuning of speed without pressure loss and the possibility of dry operation without suffering damage mean that these pumps offer unrivalled versatility. In addition, the huge choice of construction materials allows selection of optimum chemical compatibility with the fluid and/or environment without neglecting the temperature range. They are specifically designed for demanding applications with high humidity or in potentially explosive atmospheres (ATEX certification).

Description of the pump
Debem diaphragm pumps consist of a stall-prevention centrally-housed pneumatic exchangers. The new generation diaphragms (Long Life profile) are fitted to its shaft. At the two ends, the two pump casings house the ball valves and seats of the product suction and delivery duct.
A = vannes à boisseau sphérique
B = chambre de Pompege
C1 = membrane côté produit
C2 = membrane côté air
D = collecteur d’aspiration
E = collecteur de refoulement
F = moteur pneumatique
How it works
The compressed air introduced by the pneumatic exchanger behind one of the two diaphragms generates compression and pushes the product into the delivery duct, at the same time the opposing diaphragm that is integral with the exchanger shaft creates a vacuum and intakes the fluid. Once the stroke has been completed, the pneumatic exchanger diverts the compressed air behind the opposing diaphragm and the cycle is reversed.
