Shinhoo GPD series circulator is suitable for:  1. Commercial heating  2. Domestic hot water recirculation 3. Domestic heating The Shinhoo GPD and GPS circulator pumps are designed for heating, domestic hot-water, cooling and air-conditioning systems. The pumps are available in various materials, making them suitable for a range of applications. The pumps are reliable and maintenance-free. 1.Pump contains two parts: body and motor (with wet rotor).Body contains impeller, while motor includes stator, rotor, shield cover and deflating screw. 2.Tightness:the pump does not use mechanical seal. Stator and rotor are sealed with shield cover made of stainless and two heat-resistant rubber rings, which makes no leakage. 3.Lubrication of bearings and cooling of motor by inner circulation of pumped liquid. 4.Insulation class H, motor fixed with thermal protector, one speed or three speeds.

It is a one-speed circulation pump that can be used in both open and closed systems. The pump is of the wet-rotor type, l.e. pump and motor form an integral unit without a shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. The pumps are designed for circulation of liquids in heating and air-conditioning systems. Examples of typical applications are: One- and two-pipe heating systems /Boiler shunt pumps /Pumps for heating surfaces /Calorifiers/ Underfloor heating systems /Solar heating systems /Heat pump systems /Geothermal heating systems / Heat recovery systems /Two-pipe air-conditioning systems /Pumps for refrigeration units.
