BOXER - Air Operated Diaphragm Pumps


BOXER DIAPHRAGM PUMPS FOR VISCOUS MEDIA

Among the features of BOXER diaphragm pumps one can define exceptional capacity, power and strength, which makes them ideal for pumping liquids with very high viscosity up to 50000 cPs (at 20°C), even if these liquids contain suspended solids.

Diaphragm pumps are characterized by dry self-priming capacity with considerable suction head, even if the pump is not full, fine tuning of speed without pressure loss, adjustable flow and head, and the possibility of continuous operation without overload and damage. In addition, a huge choice of construction materials allows selecting  optimum chemical compatibility with the fluid and/or the environment without neglecting the temperature range.

They are specifically designed for applications in high humidity or potentially explosive environments (ATEX certification).

Diaphragm pumps with pneumatic drive are designed for pumping abrasive, shear sensitive and viscous liquids. In addition, they excellently cope with heavy and flowing liquids.

Advantages of BOXER diaphragm pumps

Pneumatic diaphragm (diaphragm) pumps have the following advantages

Mobility. The equipment is lightweight, which makes it easy to carry without additional attachments. Ease of installation. To connect the pumps, it is enough to connect the suction and pressure hoses, screw in the compressed air connection and click on the air hose.

Security. The equipment is started by simply opening the air supply valve. The only parameter that must be monitored in this case is the pressure - it should not exceed the maximum allowable values ​​set by the pump manufacturer. The ability to work "dry". Lack of liquid in the suction line is not a problem for diaphragm pumps.

Self-priming. Due to the creation of a deep vacuum, the equipment is capable of lifting liquid from a height of up to 5 meters or more with an empty inlet line. Wide range of pumped liquids. A wide range of components made of various materials will ensure chemical compatibility even with very aggressive substances. Capable of pumping viscous and dense liquids, as well as media with solids, without the threat of damage to the pump.

High abrasion resistance. Membrane equipment is well suited for the ceramic industry. Explosion-proof. These pumps do not generate sparks during operation and do not heat up above the permissible temperature. In the presence of a conductive housing, they can be used in rooms explosive with gas or dust.

Possibility to adjust performance and pressure. Relatively low price. Diaphragm pumps, in comparison with other equipment for solving similar problems, can often be bought at a more attractive price.

Ease of maintenance. No high qualification of personnel or special knowledge is required to replace components. It is enough to have the usual tools and repair instructions.

The Way It Works

The Way It Works

The compressed air generates from the pneumatic exchanger (А) through one of the two diaphragms. It compresses and pushes the product into the outlet manifold (В). The fluid is intaken as a result of decreased pressure created by the opposing diaphragm (С) that is integrated with pneumatic exchanger. After each stroke, the pneumatic exchanger diverts the compressed air to the opposing diaphragm, and the cycle is reversed.<
