Centrifugal feed pumps of PE type and electrical pump units based on them are designed to supply water to stationary steam boilers, with absolute vapor pressure up to 6.2 MPa (63 kgf / cm²). Feed water should have pH 7-9,2, the temperature not more than 438K (165 ° C) and should not contain solid particles.
Pumps are manufactured in a climatic category of a moderately cold climate – they are designed for macroclimatic regions with temperate and cold climates, placement category 4 – operation in rooms (volumes) with artificially controlled climate conditions.
The pumps are referred to goods of specific purpose of Type I (restorable).
Pumps are made within the frames of general industrial design and are not intended for use in potentially explosive and fire hazardous industries in accordance with the “Rules for Electrical Installation” (REI).
