LG, LG-B type vertical multistage centrifugal pump is for the skycraper to draining off water and a new product that developed according to the standard of national bureau of fire protection.

This kind of pump adopt outstanding water conservancy model,featuring high efficiency,wide performance range,thus to meet users' needs. In addition,this type of pump has adopted vertically,subsection structure,which is safe,steady,long life,the floor space needed is small,installation and maintenance is convenient.

Characteristics

1, Compact structure, small, small floor space needed.
2, it is convenient to change the wearing parts (machinery seal), namely "dismantling", no need to dismantle the motor.
3, adopt waterpower to balance radial and axial force, combined with the bearing
4, wearing parts adopt the high-quality wear-resisting material.
5, can equip ordinary motor of the same type.
6, mechanical seal is specially designed, the sealing is good, and the life span is long.
7, hot water type mechanical seal provided, it can pump hot water.

The structure explaining

1, vertical multistage subsection type structure, with bolt to fasten water section, midsection, surface section together, adopt water power to balance the axial force, remaining axial force is born by one or one pair of ball bearings;
2, driven by vertical motor, see from the motor end, the pump is rotating clockwise;
3, the inlet is at below, and outlet in above, relative position can be 0 ° 、 90 °, 180 ° 、 270 ° according to the request of user. Generally, the pump is dispatched from the factory 180 °.
4,suck pump mouth at below,water outlet in above, relative position its can choose 0° 、 270°one of, 180° 、 of 90°, assemble and is dispatched from the factory according to the request of user. The general pump 180°is dispatched from the factory.
5, assemble and does not need to adjust, disassembly and assembly is convenient;
6, motor can be standard Y serial ordinary types

Working condition

1, transporting clear water or other liquid that physical and chemical property is similar to water. the volumes of solid objects can not exceed 0.1%, that of unit volume. Medium with tiny particles, please prove while placing an order;
2, medium temperature: -15 ℃ - + 120 ℃
3, the system working pressure is not greater than 2.5MPa;
4, the temperature of the surrounding environment should be lower than 40 ℃ , relative humidity is lower than 95%

Main use

This type of pump is applicable for buildings, hospital, hotel, firefighting, spray, long-distance trsportation, etc.
