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

Pump group without mixer NG-47 L — Termojet direct group 1″ female thread in proprietary EPP BLACK thermal insulation for circuits operating at the full temperature of the heat generator and not requiring regulation. High flow capacity Kvs 10.2 m³/h means minimal hydraulic resistance and circuit output up to 40 kW.

The purpose of the group is to organise coolant circulation from the boiler or distribution manifold to the consumer circuit without changing the supply temperature. Valves with thermometers 0–120 °C on the supply and return lines show the actual temperature conditions and allow the circuit to be shut off for service; the built-in check valve eliminates parasitic circulation between adjacent circuits, and the isolation valve simplifies the replacement of the circulation pump without draining the coolant.

Application areas of the direct pump group: radiator heating, loading of an indirect heating boiler (DHW), ventilation circuit with air heater, pool heating. The centre distance of 125 mm is the industry standard, so the group mounts on Termojet distribution manifolds without adapters, for example the K22V.125 for 2+1 circuits; hydraulic independence of circuits in a multi-circuit boiler room is ensured by the hydraulic separator GS-26 1¼″. To a manifold with 1¼″ outlets, the group connects via adapter KP 125/150.

Advantages of NG-47 L from Termojet:

• EPP BLACK thermal insulation with seating for fittings — minimal heat losses;
• fully assembled and pressure-tested unit — installation on the manifold in minutes;
• union nuts on supply and return — fast servicing without welding;
• Ukrainian manufacture, stock availability and official manufacturer's warranty.

Technical specifications: maximum output 20 kW at ΔT=10 °C and 40 kW at ΔT=20 °C, Kvs 10.2 m³/h, connection to manifold and circuit — 1″ female thread, working pressure up to 6 bar, height 395 mm, width 250 mm, volume 0.32 l. Pump installation length — 180 mm; pump purchased separately — the energy-saving Termojet APE 25-40 pump (180 mm) is suitable.

If the circuit requires temperature regulation (underfloor heating), choose the model with a thermostatic valve in the Termojet pump group catalogue.

Frequently Asked Questions

Is the circulation pump included?
No, the pump is purchased separately. The installation length in this group is 180 mm; the energy-saving Termojet APE 25-40 (180 mm) is suitable.

How does a direct group differ from one with a mixer?
The direct group supplies coolant at full boiler temperature without regulation. For underfloor heating, choose the model with a thermostatic valve, such as NG-46.
