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.

Advantages

Easy installation and start-up

Provided with self-adaptive mode AUTO.

(inital seeting)In most case, the motor pump needs no adjustment and can be readily started and automatically adjust to meet the actul needs of systems.

High-degree comfort

Low operational noise of mtor pump and whole system.

Low energy consumption

Compared with traditional circualtion motor pumps, it has lower energy consumption. GPA series circulation motor pump is attached with Europe Energy Lable Class A marking, and the minimum energy consumption can reach up to 5W.

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.

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.
