Pump group Termojet without mixer 1" FT in thermal insulation without pump PG-47 (27)

Pump group without mixer NG-47 — straight circulation group Termojet with 1″ female thread connection for circuits operating at full heat-carrier temperature without return blending. High flow capacity Kvs 10,2 m³/h provides circuit power up to 20 kW at ΔT=10 °C and up to 40 kW at ΔT=20 °C.

Operating principle of the straight pump group: heat carrier from the boiler or distribution manifold is supplied to the circuit at full supply temperature without any regulation. The built-in check valve prevents parasitic circulation between parallel circuits; valves with thermometers 0–120 °C on the supply and return lines show the actual temperature mode and allow the circuit to be isolated for maintenance without draining the system. The isolation valve simplifies circulation pump replacement without purging the heat carrier.

Typical application scenarios for a straight pump group: radiator heating, domestic hot water (DHW) storage heater, ventilation circuit with air heater coil, swimming pool heating. The 125 mm centre distance meets the industry standard — the group mounts on Termojet distribution manifolds without adapters, for example on the manifold K22V.125 (2+1, top outlets). If the boiler room has several circuits with different pumps, hydraulic independence is ensured by the hydraulic separator GS-25 1″. For low-temperature systems with a heat pump, see Termojet heat pumps.

Advantages of pump group NG-47 from Termojet:

• fully assembled and tested at the factory — installation on the manifold in minutes;
• thermal insulation jacket included — minimum heat losses in the boiler room;
• union nut connections on supply and return — fast installation and removal without welding;
• Ukrainian manufacture: competitive price, in-stock availability, and official manufacturer's warranty.

Technical specifications: maximum circuit power 20 kW at ΔT=10 °C and 40 kW at ΔT=20 °C, Kvs 10,2 m³/h, connection to manifold and heating circuit — 1″ female thread, working pressure up to 6 bar, height 353 mm, width 261 mm, volume 0,32 l. Circulation pump installation length — 130 mm; pump not included, the Termojet APE 25-60 pump (130 mm) is suitable. For connection to a manifold with 1¼″ outlets the group uses adapter KP 125/150. Full product range — in the Termojet pump groups catalogue.

Frequently Asked Questions

Is the circulation pump included?
No, the pump is purchased separately. Installation length — 130 mm; we recommend the energy-saving Termojet APE 25-60 (130 mm).

How does a straight pump group differ from a mixing group?
A straight group supplies heat carrier at full boiler temperature without regulation — suitable for radiators, DHW, and swimming pools. For underfloor heating, choose a group with a thermostatic valve or mixer.
