Centrifugal circulating electric pumps of CVC-Т type are intended for water circulation at a temperature up to 60°С, containing not more than 0,01 % of mechanical impurities by weight and the size of particles up to 0,1 mm within the service water systems.
Electric pumps are fabricated in single-phase version rated for 220 V and three-phase version rated for 380 V.
Maximum ambient temperature under service conditions is 40°С, relative humidity of air of up to 80%.
As far as the type of protection against electrical shock is considered, the electric pumps correspond to 1st class.
Electric pumps are not designed for servicing in explosion-and-fire hazard premises.
Climatic version U3.1 as per GOST15150-69. Temperature class of electric pump unit ТF 60.
Electric pump is a monoblock unit consisting of an asynchronous three-phase or single-phase motor with synchronous speed of 50s-1 (3000 rpm) and pump section.
Pump section comprises: cast iron casing, impeller, connecting piece and coupling. Impeller is secured on the shaft by the screw. The shaft is sealed by the end seal. The casing is sealed around a joint by rubber ring.
