Compact, proven and ready to use – pump groups from the DK, MK and TK series are a new addition to our range. Instead of building a system from individual components, the installer receives a complete set: a circulating pump with valves, fittings and an insulated casing. That makes installation easier and guarantees reliability in use.
What are pump groups and what are they for?
A pump group is a ready-made assembly of components responsible for transporting the heating medium from the heat source (e.g. a boiler, heat pump or buffer tank) to the emitters – such as radiators or underfloor heating systems. Its main task is not only to circulate water, but also to control flow parameters such as temperature and pressure. In practice, using pump groups makes it easier to split heat across different heating circuits and increases the safety and efficiency of the whole system.
Why are ready-made Termet pump groups a good choice?
Unlike traditional solutions, where the installer has to collect and assemble individual parts, Termet offers a comprehensive set ready for installation. The compact, insulated casing contains the pump, valves, thermometers and the necessary safety components. For the user this is a guarantee of quality and trouble-free operation – and for the installer a significant time saving and a lower risk of installation error.
Termet pump groups are fully compatible with other system components, have clear markings (red – flow, blue – return), and their design allows convenient wall or manifold mounting. An additional advantage is EPP insulation, which reduces heat losses and protects the user from burns.
Three Termet pump group variants – matched to different system requirements
DK 25 pump group – direct circuit
The simplest and most economical version, ideal for systems where the medium temperature can be transferred directly to the emitters (e.g. high-temperature radiators). The Termet DK 25 pump group does not include a mixing valve.
Equipment:
- TERMET TF3 ADAPT 25-85/130 pump,
- ball valve with integrated thermometer (flow – red),
- ball valve with integrated check valve and thermometer (return – blue),
- EPP insulation with the option of mounting directly on the wall or manifold,
- pump ball valve.
Max. flow (Kvs): up to 4.5 m³/h.
MK 25 pump group – with mixing valve and actuator
Excellent for low-temperature systems (e.g. underfloor heating), where mixing of flow and return water is required. The Termet MK 25 pump group has a built-in actuator that allows automatic temperature control.
Equipment:
- TERMET TF3 ADAPT 25-85/130 pump,
- reversible 3-way mixing valve with adjustable bypass,
- ball valve with integrated thermometer (flow – red),
- ball valve with integrated check valve and thermometer (return – blue),
- ST electric actuator, (3.5 W, IP40, running time 135 s)
- EPP insulation with the option of mounting directly on the wall or manifold.
Max. flow (Kvs): up to 4.5 m³/h.
TK 25 pump group – with thermostatic mixing valve
A compromise solution – temperature control with a thermostatic valve, without automation. The Termet TK 25 pump group works well where dynamic temperature control is not required.
Equipment:
- TERMET TF3 ADAPT 25-85/130 pump,
- manual thermostatic mixing valve with a temperature adjustment range of 20-50°C,
- ball valve with integrated thermometer (flow – red),
- ball valve with integrated check valve and thermometer (return – blue),
- EPP insulation with the option of mounting directly on the wall or manifold.·
Max. flow (Kvs): up to 2.5 m³/h
Benefits of using Termet pump groups
A professionally designed heating system is first and foremost a matter of durability and reliability, but aesthetics and convenience also matter. Choosing ready-made Termet pump groups raises the technical standard of the system – it improves its operation and makes maintenance easier.
For the user:
- greater system reliability thanks to a ready-made, factory-tested set,
- energy-saving TF3 ADAPT pump with automatic operation control,
- compact dimensions (340×250×120 mm),
- reduced heat losses thanks to insulation.
For the installer:
- time savings, no need to assemble from individual parts,
- lower risk of errors and complaints,
- universal DN25 connections,
- easy identification thanks to color coding,
- simple maintenance and easy access to components.
A new standard for heating systems
Termet DK, MK and TK pump groups are a response to the needs of modern heating systems. Easy to install, safe, compact and functional – they ensure trouble-free operation of the heating system and give installers a more comfortable job. By choosing well-thought-out Termet solutions, you invest in quality, save time and gain peace of mind. It is a solution that simply pays off.
