A mounted pressure equalisation container ensures smooth and low-pulsation operation. A material pressure regulator installed downstream (a suitable material filter is also recommended) permits precision setting of extremely small pressures.
The technical data are based on an air inlet pressure of 8 bar. The pumps of course also function perfectly at low pressures.
Krautzberger diaphragm pumps are also used where piston or centrifugal pumps are unsuitable ? for example, for the pumping of dyes, paints, glues, dispersions, solvents, oils, glazing agents, enamels, wood preservatives, petroleum products, chocolate, sugar syrup, jam, ketchup etc.
The pump body is made of aluminium with hard-coated surface as standard. This makes the pump extremely hardwearing as well as resistant to media with a pH of between 3.0 and 8.0. The pumps are also suitable for use in the food industry.
The valves are available in either stainless steel or tungsten carbide (tungsten carbide), the diaphragms in PTFE or NBR. The pumps are equipped for wall mounting as standard but are also available on request as a unit mounted on a trolley with storage space for the material drum or as a portable unit mounted on a cover (for mounting on the material feed container (e.g. euro hobbock). Suitable stirrers for mounting on this cover are also available.
