1. Connection form

The vertical water pump is connected with the motor by the coupling, which needs to be aligned regularly; the perpendicular water pump is superimposed and connected from the bottom to the top, and the perpendicular water pump is generally called the channel pump.

2. Installation form

Compared with perpendicular water pumps, perpendicular water pumps are easier to install. The vertical pump set is handed with a base, and perfection adaptation is needed after installation.

3. conservation difficulty

Since the perpendicular water pump is composed of upper and lower layers, the conservation of the perpendicular water pump is more delicate. For illustration, to repair the impeller, it’s necessary to remove all the corridor above the impeller before repairing; while the vertical water pump is fairly easy. For illustration, the IS type pump can perform impeller conservation by removing the bay pipe.

4. bottom space

It can be seen from the appearance that the vertical water pump has a base due to its vertical structure, so it occupies a large area.

The fire pump is mainly used to pressurize and send water to the fire system pipeline. It can also be applied to industrial and urban water supply and drainage, high-rise building underpressure water supply, long-distance water supply, heating, bathroom, boiler cold and warm water circulation pressurized air conditioning refrigeration system water supply and equipment matching and other occasions. The fire pump produced by Better Technology Group Co., Ltd. has the advantages of simple structure, stable performance, high speed, small size, light weight, high efficiency, large flow, easy operation and maintenance, etc.
