Function

Centrifugal double-suction pumps D,1D,2D are designed for handling water and chemically active non-toxic liquids having a density up to 1100kg/m3, at a viscosity up to 60*10-6 m2/s (60sSt), at a temperature up to 368К (95°С), with a content of solid inclusions not exceeding 0,05% by mass and not exceeding 0,2 mm in size, at micro-hardness not exceeding 6,5 GPа (650kgf/mm2).

The pumps are referred to the items of general-purpose, aspect I (repairable ones) GOST 27.003-90.

The pumps and units are manufactured in climatic version and location category UHL 3.1, У2 and Т2 as per GOST 15150-69.

Pumps and units are supplied for export as per OST 26-06-2011-79.

The pumps and units are designed for the regions with seismic activity up to 7- points inclusive on the MSK-64 seismic scale.

The pumps and units are made in compliance with the general safety standards as per GOST R 52743-2007.

The pump units with the pumps having an embodiment index «Е» and furnished with explosion-proof electric motors may be used in explosion-and-fire hazard productions within the zones of 1 and 2 class GOST R 51330.9-99. 


Design

D,1D,2D series are centrifugal, double suction, horizontal single-stage pumps with double-sided semi-volute supply of liquid to the impeller of double-suction and with volute discharge.

The principle of operation consists in transformation of mechanical power of the drive into the hydraulic energy of the liquid due to hydrodynamic influence of the impeller blades, suction & discharge nozzles.

The electric pump unit consists of a pump and driving motor, mounted on a common welded baseplate and connected coupling.

The pump case is an iron or steel casting, which has a joint in the horizontal plane passing through the axis of the rotor.

The suction and discharge branch pipes of the pump are positioned in the bottom part of the case and are turned in different directions, owing to which the pump may be disassembled and repaired without disconnecting the pipelines and removing the electric motor.

Mounting dimensions of the flanges of the suction and discharge branch pipes are made acc. to GOST 12815-80 (version 1). At the Customer's request it is admitted to apply version 3 GOST 12815-80 for the said flanges.

The case cover extends the configuration of the passages of the case .In the top portion of the case cover there is a hole М16х1,5, closed with plug and used for connecting a vacuum pump or for linking up a vacuum treatment system, as well as for releasing the air when the pump is filled up “by gravity”.

The sense of rotation of the rotor is left-handed (counterclockwise), as viewed from the drive end. At the Customer's request it is possible to manufacture the pump with right-handed rotation of the rotor (clockwise).

Impeller – is the double-entry one: thus it allows to place the axial forces in certain equilibrium. The remaining axial forces are taken up by the radial or radial-thrust ball bearings.

To prevent leakage of liquid along the shaft provision is made in the pump case for the gland seals or for the single end-face seals.
