Pump of type D, 1D all models are new from the factory in the presence of a Kharkov pump d, pump 1D motor

Pumps centrifugal double inlet D-type and electric pump units on their basis are designed for pumping water and chemically active non-toxic liquids density to kg/m3, viscosity up to 60 10-6 m2/s (St), the temperature to 368 K (95°C) not containing solids by weight more than 0.05%, the size of more than 0.2 mm and a hardness more than 6,5 HPa (kg/mm2).

Pumps refer to the products General purpose type I (restorable) GOST 27.003-90.

Pumps and the units are manufactured in climatic version and location category UHL 3.1, U2 and T2 according to GOST 15150-69.

Pumps and electric pump units designed with export in according to OST 26-06-2011-79.

Pumps and the units are intended for areas with seismic activity up to 7 points inclusive on the MSK-64 scale.

Pumps and the units are made in accordance with the General safety requirements according to GOST R 52743-2007. Units with pumps having index "E" and equipped with explosion-proof motor, can be used in explosive and fire-hazardous production facilities in areas of class 1 and 2 GOST R 51330.9-99.

DESIGN

Pump of type D – double inlet centrifugal, horizontal, single-stage with bilateral polyproline supply fluid to the impeller bilateral the inlet and the volute outlet.

The principle pump is to convert mechanical energy of the actuator in the hydraulic energy of the fluid due to the hydrodynamic effects blade system of impeller, inlet and outlet.

Electric pump the unit consists of a pump and a drive motor mounted on common welded base frame and connected using couplings.

Case the pump is a cast iron or steel casting, which has a built-in a horizontal plane passing through the axis of the rotor.

Suction and discharge connections of the pump are located in the lower half of the casing and directed in different directions, making it possible to disassemble and repair the pump without disconnecting the pipelines and removing the electric motor.

Connecting sizes of flanges of suction and discharge ports is made according to GOST 12815-80 (version 1). At the customer's request is allowed for the execution of the flanges 3 GOST 12815-80.

Configuration the channels of the housing keeps the housing cover. At the top of the housing cover there is a hole MH,5, enclosed by the tube for attaching a vacuum pump or system is connected to the evacuation down, and to release air when the filling pump is "gravity".

Direction of rotation left (counter-clockwise) if viewed from the side drive. By Customer request it is possible to manufacture the pump with right-hand the rotation of the rotor (clockwise).

Working wheel - two-sided log that allows you basically to balance the axial forces. The residual axial forces are perceived radial or angular contact ball bearings.

For prevent leakage of fluid along the shaft in the pump housing installed the stuffing box or single mechanical seals.

APPLICATION

· in systems hot and cold water/heating

· in systems intake

· for submission the reservoir fluid in the oil fields

· for submission sea water fire extinguishing systems, marine port facilities

· for pumping water with impurity of oil products to the oil and refineries

· in chemical industry for pumping liquids similar in properties to water

· for pumping of process water in the thermal power engineering facilities, including NPP

· in metallurgical industry in cooling systems

· in systems fire industrial and civil objects, including plants with diesel driven

FEATURES/BENEFITS

· different execution according to the materials of the flow part allows to use the pumps in various industries and used for pumping water, and for pumping sea water, produced water and chemically active non-toxic liquids;

· different execution of the diameter of impellers, including according to Customer's requirement, you can choose the best parameters of the pump depending on the required characteristics on site;

· application impeller double suction allows you to balance the axial forces and to reduce the load on the bearings;

· performance flow parts for high-pressure pumps in the form of a double spiral allows to reduce the radial load on the rotor when the pump is on unrated modes;

· the presence of horizontal connector of the pump casing and the pump cover allows repair on site WHI
