Features and uses 
 G Series shield pump uses low-noise channels closed, no mechanical seal's unique structure. Sets of stator and rotor are made of stainless steel shield sealing, conveying the cooling liquid can enter the motor, so as to solve the ordinary pipeline pump resulting from the use of mechanical seal leakage of transmission media, environmental pollution, poor reliability, maintenance problems and other issues. Rotating part of the stone bearing with support, transport medium lubrication, low noise, environment-friendly upgrading of products. Because of its low noise, no leakage, reliable, maintenance-free advantages of highly trusted users. 
 G Series shield pump hot water circulation is mainly used for HVAC, industrial, urban construction water supply, fire pressurization, long-distance water and other occasions. 
 Working conditions 
 1, this series of flow range :1-1080m 3 / h, Yangcheng Fan Wai :5-105m. 
 2, the pump system pressure is 1.0MPa (or 1.6MPa), the pump suction pressure + Yang Cheng "1.0MPa (or 1.6MPa). When a user requests the system pressure is higher than 1.0MPa, shall be made when ordering. 
 3, the transmission medium is water or physical and chemical properties similar to water, medium temperature "95 ° C (N-type and NY-type) or" 150 ° C (GY-type), the user must be configured chosen outside the GY-type cooling water system; when the medium temperature is below 20 ° C, shall be made when ordering, the factory will take a special process measures.
