Appointment

Pumps of the SE type and pumping units based on them of the ASE type are designed for pumping water with a temperature of up to 180°C in heat networks.

Structure

Se network pumps – centrifugal, horizontal, spiral with horizontal housing connector, one - and two-stage with transfer pipes with two-way inlet impellers. The rotor supports are external rolling bearings with crankcase lubrication. Shaft seals – mechanical with stuffing box with supply of cooling and locking fluid (-C), interchangeable with mechanical end seals (- T).

Symbol name
