The CUBIC diaphragm pumps are known for their high performance, power and sturdiness that make them suitable for pumping fluid with a very high apparent viscosity, of up to 50.000 cps (at 20° C) even when suspended solid parts are present.
The dry suction capacity from considerable suction heights when the pump is not flooded, together with the possibility to fine-tune the speed without a loss in pressure, flow rate and head, and the possibility of loadless operation without causing any damage, make these pumps extremely versatile.
The vast choice of composition materials allows you to determine the best chemical compatibility with the fluid and/or the environment without neglecting the temperature aspect. Their construction makes them particularly suitable for severe environments with high humidity or in potentially explosive environments (ATEX certification). |

Description
Diaphragm minipumps are composed of a coaxial centrally housed pneumatic motor, with newgeneration diaphragms (Long Life profile) fixed to the shaft. At the two ends, the two pump bodies house the ball valves and the relative seats of the product intake and delivery ducts.
Coaxial pneumatic exchangers
The pneumatic exchangers that DEBEM has developed and innovated in a revolutionary manner, patenting the most reliable and long-lasting system available today, are the heart of the pneumatic diaphragm pumps. The device is pneumatically unbalanced thanks to a stallprevention circuit that ensures optimum operation even in the most critical conditions.
The diaphragms
Diaphragms are the parts that are most affected and stressed by the suction and pumping process, during which they must also resist to chemical aggression and fluid temperature. Therefore, evaluating and choosing the diaphragms correctly plays an important role in extending the life of the diaphragms and affects investments and maintenance costs. Thanks to a modern design process, destructive tests and thorough analyses of the results, DEBEM has developed a new generation of diaphragms called LONG LIFE that offer, thanks to their profile and construction, a greater work surface and an improved load redistribution that reduces material stress and yield to a minimum. |
