Pump group NG-47 without mixer — a direct Termojet 1″ FT group in the proprietary EPP BLACK thermal insulation for circuits operating at the full temperature of the heat source. The high flow capacity Kvs 10.2 m³/h means minimal hydraulic resistance and a circuit output of up to 40 kW at ΔT=20 °C. The task of a direct group is to provide circulation of the heat carrier from the boiler or distribution manifold to the consumer without controlling the supply temperature. The standard center-to-center spacing of 125 mm allows the group to be mounted on a Termojet manifold without any adapters, and the shut-off valves isolate the circuit for servicing or pump replacement without draining the entire system. Areas of application: radiator heating, charging of an indirect-heating tank (DHW), a ventilation circuit with a heater coil, high-temperature branches of solid-fuel boiler rooms. In heat-pump systems, the direct group serves circuits without admixing — for example, charging 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 the NG-47 by Termojet: EPP BLACK thermal insulation — minimal heat losses and a tidy appearance of the unit; high flow capacity Kvs 10.2 m³/h — reserve for high-power circuits; a fully factory-assembled unit — mounting on the manifold in a matter of minutes; in-house 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 , 1″ FT connection, center-to-center spacing 125 mm, working pressure up to 3 bar. Pump installation length — 180 mm; the pump is not included — we recommend the energy-saving Termojet APE 25-60 pump (180 mm) . Models with a thermostatic valve for underfloor heating are in the catalog of Termojet pump groups . FAQ When to choose a direct group and when one with a mixer? A direct one — for radiators, a DHW tank and ventilation, where the circuit operates at the boiler temperature. Underfloor heating requires a group with a thermostatic valve. Which pump fits the NG-47? A circulation pump with an installation length of 180 mm — for example, the energy-saving Termojet APE 25-60 (180 mm).

Pump group NG-48A L with the A-413 actuator-controller — an automated Termojet 1″ FT mixing unit in the proprietary EPP BLACK thermal insulation for circuits with controlled supply temperature. The "L" version means the supply line is on the left, and the actuator is already mounted on the mixer — the unit is ready to operate right after installation and power connection. How it works: the actuator-controller A-413 (230V, 3-point ON/OFF control) turns the three-way mixing valve and admixes the cooled return into the supply — the circuit temperature is regulated automatically, without manual adjustment of a thermostatic head. The actuator torque is 6 Nm, the 90° turning time is 120 seconds, protection class IP42, CE and RoHS certificates. Valves with 0–120 °C thermometers on the supply and return show the actual mode and allow the circuit to be shut off for servicing. Areas of application: underfloor heating, combined "underfloor + radiators" systems, circuits with weather-compensated control, connection of solid-fuel and gas boilers. Precise automatic temperature control makes the group suitable also in low-temperature heat-pump systems — see Termojet heat pumps . In the boiler room, the group is mounted on the distribution manifold K22V.125 (2+1, outlets up) with the standard center-to-center spacing of 125 mm. Advantages of the NG-48A L by Termojet: A-413 actuator-controller included — automatic temperature regulation without additional settings; EPP BLACK thermal insulation with seats for the fittings — minimal heat losses; a fully factory-assembled and tested unit — installation in a matter of minutes; Ukrainian manufacturing: affordable price, stock availability, official warranty. Technical parameters: maximum output 20 kW at ΔT=10 °C and 40 kW at ΔT=20 °C , Kvs 6.3 m³/h, 1″ FT connection, working pressure up to 3 bar. Circulation pump installation length — 180 mm; the pump is not included — the energy-saving Termojet APE 25-60 pump (180 mm) is a good fit. A simpler alternative without an electric actuator is the NG-46 pump group with a thermostatic valve ; see the entire product range in the catalog of Termojet pump groups . FAQ Is the circulation pump included? No, the pump is purchased separately. The installation length in this group is 180 mm, so the Termojet APE 25-60 (180 mm) is the optimal fit. What does the "L" version mean? The supply line is located on the left — this makes it convenient to arrange groups on the manifold depending on the boiler-room layout.

Pump group with thermostatic valve NG-46 L — a pre-assembled Termojet unit for circuits that require regulation of the heat carrier temperature, in the proprietary EPP BLACK thermal insulation. The thermostatic valve maintains the supply temperature in the range of 25–55 °C , and the letter "L" means the left-hand position of the supply line — for a mirrored boiler-room layout. The operating principle is based on admixing the return: as soon as the supply temperature exceeds the value set on the thermostatic valve, the three-way thermostatic valve adds cooled heat carrier from the return line — the circuit steadily receives the set temperature regardless of the boiler's operating mode. This protects the underfloor heating from overheating without expensive electronic automation: the group operates fully autonomously. Typical application scenarios: underfloor heating, low-temperature radiator heating, circuits with supply-temperature limitation in systems with solid-fuel and gas boilers. Precise maintenance of a low temperature makes the group suitable also for connecting heat-pump systems — if you are selecting equipment for low-temperature heating, see Termojet heat pumps . If the layout requires the supply on the right, choose the mirrored NG-46 pump group with a 25–55 °C thermostatic valve (base version) . Advantages of the NG-46 L by Termojet: EPP BLACK thermal insulation with seats for the fittings — minimal heat losses and a tidy boiler-room appearance; a fully factory-assembled and tested unit — installation in a matter of minutes; left-hand supply connection — flexibility in arranging neighboring groups on the manifold; Ukrainian manufacturing: affordable price, stock availability, manufacturer's warranty. Technical specifications: maximum circuit output 15 kW at ΔT=10 °C and 30 kW at ΔT=20 °C , Kvs 3.5 m³/h, 1″ FT connection, working pressure up to 3 bar, thermostatic valve range 25–55 °C. Circulation pump installation length — 180 mm; the pump is not included — the energy-saving Termojet APE 25-60 pump (180 mm) is the optimal fit. Direct groups and other versions are in the catalog of Termojet pump groups . FAQ What does the "L" in the group's name mean? The left-hand position of the supply line. The mirrored version with the supply on the right is the base NG-46: this allows neighboring circuits to be neatly routed on a single manifold. Is the circulation pump included? No, the pump is purchased separately. The installation length is 180 mm, so the energy-saving Termojet APE 25-60 (180 mm) is the optimal fit.
