Axial horizontal one-stage pumps with a console location of the pump impeller is intended for pumping over waters with the 2200 kg/m³ maximum density of firm particles, in temperature no more than 308 K (35ºС).
The rotor turns in two radial two-rows bearing rolling support which is lubricated with liquid lubricant. The axial effort from reaction of water and weight of a rotor is perceived by a persistent conic roller thrust-bearing.
The direction of rotation of a rotor - clockwise if to take a detached view from the side of the electric motor. Transfer of a torsion torque from an electric motor shaft to a pump shaft is carried out by means of bush-finger muff.
A material of the basic pump details: the bush of the pump impeller and the pipe bend - a carbonaceous steel; the correcting device and an blacket - grey pig-iron; a shaft, the chamber and pump impeller blades - stainless steel.
A pump symbol:
O - axial;
Г - with horizontal shaft;
5 - number of model of the pump impeller, sm;
87 - diameter of the base driving wheel, sm;
A - with the pump impeller which is distinct from base, and the cylindrical chamber;
У - a climatic modification.
