Pumps can be used in single pipe or double pipe heating system,also can be applied to city apartments,suburb villa,cooling, air conditioning, boilers and solar system etc.

1. Pump contains two parts:hydraulic section and motor (with wet motor). Hydraulic section contains pump housing, impeller while motor includes stator,rotor,cartridge and air-venting nut.

2. Sealing:the pump does not use mechanical seal. Stator and rotor are sealed with cartridge made of stainless steel and two hart-resistant rubber rings, which ensure no leakage.

3. Lubrication of bearing and cooling of motor by inner circulation of pumped liquid.

4. Insulation class H, one speed or three speeds.

Pump with cast iron housing is widely used for delivering water for room heating. Pump with bronze housing is largely used in the floor heating system. For delivering domestic hot water recommend using pump stainless steel housing or bronze housing.

Medium Liquid

1. Thin, clean, non-corrosive and non-explosive liquid that does not contain any solid particles, fibers or mineral oil.

2. The pump must never be used to transport flammable liquids such as diesel and gasoline.

3. If the circulating pump is used in an application with high viscosity, the hydraulic performance of the pump will be reduced. Therefore, when selecting a pump, the viscosity of the liquid medium to be transported must be considered.
