pump calpeda NCD50-120/280

calpeda NCD50-120/280  motor and pump form a single unit without a shaft seal, this design uses two seals to prevent fluid from flowing to the rotor.

In-line pump casing with suction and discharge pipelines in one line (multi-row version). All parts and bearings of the pump are lubricated by the pumped liquid. Minimal inlet pressure should be maintained to prevent cavitation.

Apply

Pumping of clean, uncontaminated liquids that do not contain abrasive inclusions and do not come into contact with pump materials (solids content Max.-0.2%). It is applied in circulating systems of heat supply, conditioning and cooling. It is used both in household and in industrial spheres of a national economy. Modification: NC - single pump; NCD is a dual pump.
