DIAPHRAGM PUMPS
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 = ball valves |
 |
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.
Pneumatic exchangers
|
The heart of an air-operated diaphragm pump consists of the pneumatic exchanger that DEBEM has succeeded in developing and innovating in a revolutionary manner, patenting the most durable and reliable system the market currently has to offer. This device introduces compressed air to alter the pressure balance of the diaphragms assisted by a stall-prevention circuit that ensures optimum performance even under the most critical conditions or with low-pressure compressed air supplies (min 2 bar).

Debem diaphragms
THERMOPLASTIC DIAPHRAGM They are made from thermoplastic polymers that provide high mechanical stress resistance and distribution.
PTFE DIAPHRAGM This material is noted for its excellent resistance to high temperatures, chemicals and corrosive agents. DEBEM PTFE diaphragms are subjected to a double heat treatment in order to increase elasticity and service life. Each batch undergoes random destructive testing in order to verify its performance. |

Installation
The pumps must be installed vertically with special bolts on the feet or holes provided.

Chemical compatibility
The type of liquid, temperature and working environment are factors to be considered when deciding on the best choice of construction materials for the pump and its correct chemical compatibility. Some examples are given in the following table:
