Pump group Termojet without mixer 1" FT in EPP BLACK thermal insulation without pump PG-47EPP

Pump group NG-47 without mixer — Termojet direct group 1″ female thread in proprietary EPP BLACK thermal insulation for circuits operating at the full temperature of the heat source. High flow capacity Kvs 10.2 m³/h means minimal hydraulic resistance and circuit output up to 40 kW at ΔT=20 °C.

The task of the direct group is to organise coolant circulation from the boiler or distribution manifold to the consumer without regulating the supply temperature. The standard centre distance of 125 mm allows the group to be installed on a Termojet manifold without any adapters, and the shut-off fittings isolate the circuit for maintenance or pump replacement without draining the entire system.

Application areas: radiator heating, loading of an indirect heating boiler (DHW), ventilation circuit with air heater, high-temperature branches of solid-fuel boiler rooms. In heat pump systems, the direct group serves circuits without mixing — for example, loading a buffer tank; for the equipment itself, see the Termojet heat pumps page. In a multi-circuit boiler room, the group is complemented by the manifold K22VN.125 (2+1, up+down) and the hydraulic separator GS-26 1¼″.

Advantages of NG-47 from Termojet:

• EPP BLACK thermal insulation — minimal heat losses and a neat appearance of the unit;
• high flow capacity Kvs 10.2 m³/h — reserve capacity for powerful circuits;
• fully factory-assembled unit — installation on the manifold in minutes;
• own manufacturing in Ukraine, stock availability, manufacturer's warranty.

Technical specifications: maximum output 20 kW at ΔT=10 °C and 40 kW at ΔT=20 °C, connection 1″ female thread, centre distance 125 mm, working pressure up to 3 bar. Pump installation length — 180 mm; pump not included — we recommend the energy-saving Termojet APE 25-60 pump (180 mm). Models with thermostatic valve for underfloor heating — in the Termojet pump group catalogue.

Frequently Asked Questions

When to choose a direct group and when one with a mixer?
Direct — for radiators, DHW boiler, and ventilation where the circuit operates at boiler temperature. For underfloor heating, a group with a thermostatic valve is required.

Which pump suits the NG-47?
A circulation pump with an installation length of 180 mm — for example, the energy-saving Termojet APE 25-60 (180 mm).
