[Three rain valve to recommend the star product - Mechanical seal] Description: sewage pump is a pump and motor Siamese, and also sneaked under liquid pumps work, and generally horizontal or vertical pump sewage pump phase than WQ35-5-0.75 pumps, sewage pumps compact, small footprint. Easy installation and maintenance, a large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance very easy. Continuous operation for a long time. Due to pump sewage pump and motor coaxial shafts short, rotating parts and light weight, so the loads on the bearings (radial) is relatively small WQ20-7- 0.75 pumps, life is much longer than the average pump. There is no cavitation damage and irrigation water and other issues. Especially after a little to the operator has brought great convenience. Vibration noise, motor temperature low environmental pollution. [Three rain valve to recommend the star product - Mechanical seal] Description: sewage pump automatic coupling installation can be quick and easy pump slip along the rail into the water medium, the pump and the base automatic coupling seal. Installation and maintenance upgrade is very convenient. In this form of security types, the pump is connected with the coupling means, coupled to the base fixed to the lower part of the pump sump pump can automatically move up and down in the guide rail, when the pump down WQ6-18-0.75 pump, the coupling means is automatically coupled to the base and coupling, while the lift pump is automatically coupled from the base. This approach can be equipped with a hydraulic switch according to user requirements, intermediate terminal box and automatic protection control cabinet. In the selection, should specify the type of pump, installation, pool depth, pump control and protection methods in order to provide optimal system. If the user special needs, I can provide specialty materials plant pumps. WQ35-5-0.75 pumps, water pumps GB selected three rain (already certified, Zhangzhou pumps supplied by three rain Valve Co., Ltd. of Tianjin. Tianjin three rain Valve Co., Ltd.
