LG series high-rise building water pump

LG vertical multi-stage Centrifugal Pump is especially suitable for high-pressure building, hotels, office buildings and other high-rise buildings, constant pressure water supply, fire fighting, spray water supply equipment supporting pumps; also suitable for chemical process cooling tower automatic water supply; system voltage regulation, production Process water, long-distance transportation, boiler feed water and other water supply equipment. The liquid that can be transported is normal temperature (<80 ° C) (hot water type can transport the medium with a temperature less than 105 degrees), clear water or a normal temperature medium with physical and chemical properties similar to water.

LG type high-rise building Water Pump product overview

The LG-type high-rise building feed water Pump is a vertical single-suction multi-stage segmented centrifugal pump for conveying normal temperature and clear water and physical and chemical properties similar to clean water. The LG series pump is installed vertically. The motor shaft and the pump shaft are connected by a claw type coupling. It has the advantages of compact structure, low noise and small floor space. It is mainly used for high-rise building water supply, and can also be applied to factories, mines and enterprise water supply. Drainage and circulating water for low-pressure boilers. LG is a vertical, single-suction, multi-stage, split-type centrifugal pump with suction and discharge ports located on the inlet and outlet sections. The rotor component is composed of a shaft, an impeller, an impeller sleeve, a bushing and the like, and the water inlet section, the middle section and the water outlet section are connected by a tension bolt. The shaft seal is sealed with a soft packing or mechanical seal and lubricated and cooled with pressurized water from the balance chamber. The product implements the standard of JB/T2727-93 "Vertical multi-stage simple centrifugal pump type and basic parameters". LG is a vertical, single-suction, multi-stage, split-type, disposable centrifugal pump with suction and discharge ports on the inlet and outlet sections.

LG type high-rise building water pump application range

LG vertical multistage centrifugal pump is especially suitable for high-pressure building water supply, fire-fighting and spray water supply equipment for residential buildings, hotels, office buildings, etc. It is also suitable for automatic water supply of chemical process cooling towers; system voltage regulation, production Process water, long-distance transportation, boiler feed water and other water supply equipment. The liquid that can be transported is normal temperature (<80 ° C) (hot water type can transport the medium with a temperature less than 105 degrees), clear water or a normal temperature medium with physical and chemical properties similar to water.

LG type high-rise building water pump product features

1. Low pump cost: The high-speed motor is used to make the pump light in weight, small in size and low in cost. For example, the protective cover can be placed outdoors.

2, less operation, maintenance costs: the use of reliable mechanical seals, low failure rate, with less operating and maintenance costs.

3. This series of pumps adopts the disassembled structure, which is convenient for users to replace the wearing parts such as mechanical seals. It is convenient to install and repair, and there is no need to dismantle the pipeline system. The pump inlet and outlet are of the same diameter, simplifying the connection of the pipeline.

4. The series and parallel operation modes of the pump can be adopted according to the needs of flow and lift.

5, according to needs, the suction port and the spout can be installed in the same direction or 90 °, 180 °, 270 ° several different directions to meet different connection occasions.

6. The pump head can be increased or decreased according to the needs of the pump stage and combined with the outer diameter of the cutting impeller, without changing the installation footprint.

7. The structure is novel and the operation is reliable: the balance drum (disc) is eliminated, and the axial force adopts hydraulic balance, which completely solves the problem that the balance drum is easy to rust, easy to bite and easy to wear, and the operation is more reliable.

8, unique components, reduce noise: unique hydraulic components design, good over-current performance, reduce flow noise on the ground.
