Circulator pump Termojet XPS 25/6/130 mm

Circulating pump Termojet XPS 25/6/130 mm — a circulating pump for heating and underfloor heating systems with a cast-iron body and ceramic motor shaft. Installation length 130 mm, threaded connection 1½″, maximum power 100 W, maximum head 6 m, maximum flow rate 3 m³/h. The pump is designed for forced circulation of the heat-transfer fluid and is suitable for closed water heating systems.

Technical Specifications

Design Features and Differences from the APE Series

The XPS 25/6 pump is a traditional design with a cast-iron body and copper stator winding. Maximum power of 100 W matches the level of unregulated pumps of the same size class. Protection rating IP42 (protection against solid particles and dripping water). Unlike the APE series with an ECM motor and smooth speed control from 5 to 45 W, the XPS 25/6 operates at fixed power. Cast-iron body — high mechanical strength, resistance to water hammer and mechanical loads.

Applications

• Heating systems requiring reliable forced circulation of heat-transfer fluid without electronic regulation.
• Underfloor heating — the 130 mm installation length is compatible with pump group NG-46 (130 mm) and pump group NG-48 with mixer (130 mm).
• Air conditioning systems — circulation of cooling agent.
• Facilities where simplicity and mechanical reliability are more important than consumption regulation.

XPS 25/6 or APE — Which to Choose?

If you need automatic speed regulation, Δp-c and Δp-v modes, consumption from 5 W, and an ECM-class motor — the APE series is the right choice. The XPS 25/6 with its cast-iron body and 100 W power is a reliable classic design for systems where regulation is not required but mechanical durability and simplicity matter. Both pumps have a 130 mm installation length and are compatible with the same Termojet pump groups.

XPS 25/6 and Heat Pump Systems

If the system includes a heat pump and maximum efficiency at minimum consumption is important — we recommend considering the APE series with an ECM motor. For systems where the heat pump serves a zone with a fixed load and regulation is not required, the XPS 25/6 will provide reliable circulation.

Features:

• cast-iron body — mechanical strength and durability;
• ceramic motor shaft — wear resistance;
• installation length 130 mm, thread 1½″ — standard installation;
• fluid temperature up to 110°C, IP42.

Frequently Asked Questions

Can the XPS 25/6 be installed instead of an APE pump of the same installation length?
Yes, the 130 mm installation length and 1½″ thread are compatible. Note that the XPS 25/6 does not have automatic speed regulation and consumes up to 100 W, whereas the APE consumes from 5 to 45 W depending on load.

Is the XPS 25/6 compatible with Termojet 130 mm pump groups?
Yes. The pump is compatible with pump groups NG-46 and NG-48 designed for a 130 mm installation length. The list of groups is available in the Termojet pump group catalogue.
