Vortex pumps (pumping units) type VK, VKS, EKR

Vortex pumps VK, VKS, ASD is used in systems with small feed and a relatively high pressure. Pumps VK, VKS, ASD - vortex, single-stage, horizontal cantilever. In the housing and the pump cover is made the working chamber of the flow part, representing an annular channel which is connected with the inlet and outlet nozzles of the pump. The movement of liquid in the annular channel and making it the necessary energy carried by the impeller, representing disc with radial vanes. Video conferencing - self-priming pumps. For ensure self-priming to a discharge tube of the pump is set cap-extender, which allows pre-filled pump videoconferencing to pump out air from the suction pipe. ASD - pumps with heating - for pumping legkonastraivaemy liquids. Pumps have ASD cover and heat the disk, which together with the cover to form a chamber heating. Shaft pumps VK, VKS, ASD rotates in two ball bearing piers placed in the bores of the bracket. Shaft seal - oil seal with soft padding. The pump is driven from the motor through the connecting the clutch.
Pumped liquid:

Vortex pumps VK, VKS, SAIs are designed for pumping water and other liquids similar to water viscosity -up to 36•10-6 m2/s (36 cSt) and chemical activity, with solid content inclusion by weight of 0.01%, not more and not more than 0.05 mm, which materials flow part do not allow linear speed solid corrosion than 0.1 mm/year according to GOST 9.908-85.

The pumps are made with Salnikov shaft seals and do not allow pumping of flammable, hazardous and flammable liquids. Pumps (aggregates) are not intended for use in explosive and flammable the productions.
Material of main parts of the flow pumps are manufactured in the following versions:
VK - version A (cast iron), B (bronze) (stainless);
VCS - version a, B, K;
ASD - performance And;
The temperature of the pumped fluid pumps (units):
execution And from 258 to 358 K (-15 to +85°C)
the execution of B and from 233 to 358 K (-40 to +85°C).
