Circulator pumps

GPA III series
Suitable for:

·Commercial heating

·Commercial hot water recirculation

·Domestic hot water recirculation

·Domestic heating

·Industrial heating

·Solar system

·Air conditioning system

·Integrated in heat pump

Electronically controlled circulator pumps for domestic building and thermal solar systems.
Shinhoo  GPA III  pumps are high-efficiency circulators, designed for heating, air conditioning, heat pump and thermal solar systems. The ideal choice for basic functionality needs. Applicable as a universal upgrade and replacement pump.
The pump features three constant-curve modes, proportional pressure curves, constant pressure curves, Auto and night mode. The speed can also be controlled by a low-voltage PWM signal from a controller to optimize the system performance, both PWM1 for heating and PWM2 for solar systems are available.



High-efficiency circulators with screwed connection, EC motor and integrated electronic power control, designed for circulating liquids in heating, air conditioning and solar systems. With an energy efficiency index (EEI) at the ErP benchmark for most efficient circulators it contributes to energy savings.

The ideal choice for basic functionality needs.

Advantages

Intuitive one-button operation makes selection of any control mode simple

No external motor protection required reducing installation time

High-torque start improves startup under harsh conditions

Maintenance free and noiseless due to canned-rotor design and use of robust components

Fast connection plug makes electrical installation quick, safe and easy

Insulating shells  are available to minimize heat loss in heating systems

The pump also features six control modes – with total ten curves

Proportional-pressure control

Constant-pressure control

Constant-curve mode

Auto

Night mode

PWM external control

LEDs indicate the actual operating status.
The pump has a ceramic shaft and radial bearings, carbon thrust bearing, stainless-steel rotor can, bearing plate and rotor cladding, composite impeller, all of which contribute to long life.
Best magnet material ensures the high efficiency of motor and pump. 
The pump is self-venting through the system, which contributes to easy commissioning. The compact design with integrated control box and control panel on side of the motor fits into most common installations.
The pump housing is made of cast iron and electro coated to improve the corrosion resistance.
The motor is a synchronous permanent-magnet/compact-stator motor characterized by high efficiency.
The pump speed is controlled by an integrated frequency converter incorporated in the control box.
The pump equipped with different fast connection solutions (fast connector, TE, Molex etc) to fulfill the requirements of different systems.
