Two-way GPO pump group heating circuit set

Product overview

The two-way GPO pump group heating circuit set is a state-of-the-art solution for circulating the working fluid in central heating, process heating, and cooling systems. Its compact design and factory-preassembled components allow it to integrate seamlessly into existing systems and ensure smooth operation.

Applications and operating modes

This pump group is ideal for efficient heat distribution in heating circuits, process heat applications, and cooling circuits. The integrated circulation pump supports three operating modes: Δp-c (constant pressure difference), Δp-v (variable pressure difference), and constant speed.

This allows the system to adapt optimally to changing requirements, ensures consistent temperatures and at the same time minimizes energy consumption.

Equipment and components

The standard equipment includes two ball shut-off valves with integrated thermometers and a check valve in the supply line. These fittings enable easy maintenance, quick temperature control, and reliable backflow protection.

The Wilo Para SC circulation pump with a 130 mm connection spacing ensures reliable pumping performance. Tailor-made thermal insulation reduces heat loss and ensures particularly quiet operation.

Technology

The Wilo Para 25/6 SC pump operates on 1~230 V at 50–60 Hz and consumes only 3 to 43 W. The maximum pressure is 6 bar, and the maximum fluid temperature is 90 °C.

The pump features a connection spacing of 125 mm and compact dimensions of 390 × 275 × 140 mm (L × W × H) and weighs 5.3 kg. Upper connections: 2 × 1″ female thread; lower connections: 2 × 1½″ male thread.

With a performance coefficient EEI ≤ 0.20 and a current consumption of only 0.44 A, the unit offers maximum energy efficiency and low operating costs.

Advantages at a glance

The pre-assembled pump assembly shortens installation times and minimizes coordination effort. Integrated thermometers in the shut-off valves allow immediate temperature control without the need for additional measuring devices.

A highly efficient pump motor with low energy consumption sustainably reduces operating costs. Thermal insulation reduces heat loss and ensures quiet operation.

A check valve in the supply line ensures a safe and controlled flow of medium. The result is a maintenance-friendly, long-lasting system for a wide range of heating and cooling applications.
