Product Overview

GN/GNL vertical condensate pump is a two-stage single suction centrifugal condensate pump, which is used to pump condensate in the condenser and 750-3000kw steam turbine generator unit to pump condensate or other liquids with physical and chemical properties similar to water. The liquid temperature shall not exceed 80 ℃.

Structure description of GN/GNL vertical condensate pump:

The GN type condensate pump is horizontal, and the fixed part is mainly composed of inlet section, middle section, outlet section, bearing body, guide vane and sealing ring. The axial force of the rotating part is borne by the ball bearing, while the radial force is borne by the ball bearing and the sleeve bearing installed on the guide vane.

There are cooling chambers around the packing and on the bearing body, which can be connected to the cooling water. The water inlet direction is axial, and the water outlet direction is vertical. The horizontal structure is light, but the pipeline needs to be disassembled for maintenance.

The GNL condensate pump is vertical, the pump body and pump cover are separated along the axis, the axial force of the rotating part is borne by the ball bearing, and the radial force is borne by the ball bearing and sleeve bearing. The water inlet and outlet of the pump are cast on the pump body. There are semicircular pump feet at the lower part of the pump body and semicircular supports at the upper part. The support is mounted on it. The motor is mounted on the support. The vertical pump occupies a small area and is convenient for maintenance.

The flow passage components of the pump are made of cast iron, and the shaft seal is a packing seal. Seen from the motor end to the pump, it rotates counterclockwise. Complete sets of pumps, motors, couplings, bases, check valves and gate valves shall be supplied. If there are special requirements, we will be informed when ordering, and we will provide a series of high-quality services in design, manufacturing, testing, installation, maintenance, and training of operators.

Rotation direction: seen from the motor end, the pump rotates counterclockwise

Material of main parts: the flow passage components of the pump body, pump cover, sealing ring and shaft sleeve are made of cast iron, the impeller of the N-type condensate pump is silicon brass, and the inducer is aluminum iron bronze. The shafts are made of high-quality carbon steel.

The complete range of pumps: pumps, motors, couplings, check valves and gate valves are supplied in complete sets.
