CR – DISPLACEMENT GEAR PUMP

For high freezing point fluids.

Suitable for the supply, circulation, transfer, loading/unloading of products for the petrochemical, detergents, food and confectionery, chemical-pharmaceutical industries.

This pump, equipped with a heating jacket, is suitable for handling those products which, being at room temperature, in a solid or paste-like state, could not otherwise be pumped.

These include bitumens, waxes, chocolate, glues, greases, resins and products which in turn require preheating.

The jacket, designed to guarantee a large heat retention surface, can be heated with water, diathermic oil and steam.

The pump is built and tested to guarantee total separation of the product pumped by the heating fluid.

Executions according to applications using materials suitable for the fluids to be pumped (for body, lids, bushes, gaskets and seals).

The pumps of this family can be produced with parts in cast iron (CR), stainless steel AISI 316 (CRX) or a combination of these and carbon steel.

The pumps are available with or without built-in bypass valve. In the construction, particular attention is paid to heat treatments and sealing elements, in line with technological developments.
Special executions upon request.

Also available with special magnetic drive coupling [also retrofittable (MC)].
