Shinhoo GPA IV circulator pump is the ideal choice for almost any building project – old or new. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, GPA IV is ideal for engineers and specifiers looking to create high-performance heating and cooling systems. The pump is maintenance-free due to the canned-rotor type design. This also means that pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. GPA IV features PWM and 0-10V external control. GPA IV is the superior choice for a wide range of heating and cooling applications, including:
|
Mixing loops
Heating surfaces
Air conditioning surfaces
Ground-source heat pump systems
Smaller chiller applications.

GPA IV is a single-phase pump and characterized by having the controller integrated in the control box. The pump housing is available in both cast-iron and stainless-steel versions. The composite rotor can is carbon-fiber reinforced, the bearing plate and rotor cladding are made of stainless steel and the stator housing is made of aluminum. The power electronics are air-cooled. The pump speed is controlled by an integrated frequency converter.
