Diaphragm pumps

We market Kelva’s full range of air driven diaphragm pumps together with their LV level control unit. Membrane pumps are widely used in industry to pump everything from aggressive liquids to viscous emulsions.

The pumps have the advantage that they are fully air driven and no electric motors are required. This means that our pumps are ATEX approved and can be used in areas with explosion hazard.
