Pump Group

Features

1.Adopt frequency conversion control with obvious energy-saving effect;

2.Auto/manual switching function ensures the stability of the water system;

3.Independently researched and developed advanced controller and frequency-conversion shift, precisely ensuring constant pressure for water supply according to water consumption variation;

4.Equipped with RS485 remote monitoring function;

5.When the water pump fails, the system will start the next normal pump operation automatically;

6.Non-impact of pipe network pressure supplies constant pressure for water supply;

7.Soft-start of water pump circling, stable start and stop prevent power grid from impacting by starting current;

8.First-start and first-stop operation achieves organized working of water pump to prolong the service life of the water pump.

9.Modular and innovative design concept enables the supplying of pendent pump that with two or several pumps to achieve any flow and ensure continuous operation.

10.Available to cover all the flows and pressures required by the industrial process;

Application

It is applicable to centralized constant-pressure water supplying system that is suitable for large power, variable flow and frequent start occasions, which features high-efficient system and obvious energy-saving effect. It also can be used for reforming the water tank and other forms of water supply.

Characteristic Relation of Frequency Conversion Control

In the Fig., it shows 360°rotation n1 and rotational speed n2 after frequency conversion, the lift difference is △H, and the shaft power Pa-P=△P is greater than Pb-Pa, which indicates the voltage stabilizing and power saving function can be achieved by frequency conversion control.
