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

Pump group without mixer NG-47 — a pre-assembled Termojet unit with 1″ female thread connection in thermal insulation for circuits that do not require coolant temperature control. High flow capacity Kvs 10.2 m³/h means minimal hydraulic resistance, and the circuit output reaches 40 kW at ΔT=20 °C.

The purpose of the direct pump group is to organise coolant circulation from the heat generator or distribution manifold to the consumer circuit at full supply temperature, without mixing. Valves with thermometers 0–120 °C on the supply and return lines show the actual circuit conditions and allow it to be shut off for service; the built-in check valve eliminates parasitic circulation between adjacent circuits, and the isolation valve allows the circulation pump to be replaced without draining the coolant. Union nut connections make installation and removal quick, without welding.

Application areas: radiator heating, DHW boiler heating, ventilation circuit, pool heating. The standard centre distance of 125 mm allows the group to be mounted directly on Termojet distribution manifolds, and to a manifold with 1¼″ outlets via adapter KP 125/150. The direct group is also suitable for unregulated circuits of low-temperature systems: if you are designing heating with a heat pump, see Termojet heat pumps. For an underfloor heating circuit where temperature must be limited, choose the NG-46 pump group with thermostatic valve 25–55 °C.

Advantages of NG-47 from Termojet:

• fully assembled and factory-tested unit — installation on the manifold in minutes;
• thermal insulation housing with group mounting bracket — minimal heat losses and a neat boiler room;
• pump installation length 130 mm — compatibility with the most common circulation pumps;
• Ukrainian manufacture: competitive price, stock availability, 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 heating circuit — 1″, working pressure up to 3 bar, height 353 mm, width 261 mm, volume 0.32 l. Pump not included — the energy-saving Termojet APE 25-60 pump (130 mm) is the optimal choice.

Direct groups of other sizes and models with mixer are available 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 130 mm; we recommend the energy-saving Termojet APE 25-60 (130 mm).

Which circuits are suitable for a group without a mixer?
Those operating at full boiler temperature: radiators, DHW boiler, ventilation, pool. For underfloor heating, choose the model with a thermostatic valve — NG-46.
