The CR pumps are robust standard-priming sanitary, centrifugal pumps with screw impellers.

The pumps are equipped with a clamp around the pump housing, so that the inside of the pump can be quickly and easily cleaned. The pump housing can also be rotated so that the press connection can be rotated into more positions. The connections are made compliant with DIN 11851, but optionally these pumps are also available with flange connections.The pump housing is made of thick walled cast stainless steel AISI 316.

The pumps are equipped with standard IEC electric motors with a speed of 1450 or 1000 rpm which can also be supplied with a stainless steel motor casing. Between the electric motor and the pump housing, a bell housing is placed with an extra bearing.

The pumps are ideal for pumping low viscous liquids containing solids,when the chemical resistance of the materials that come into contact with the liquid must be considered.

The max. temperature of the liquid that can be pumped is 90 deg C (depending on the suction head).

The mechanical seal can be completely matched to the specific properties of the liquid to be pumped.

This may range from a single mechanical seal to a double mechanical seal with a flush seal which is available in many material combinations.
