Compact pump group HKM20 with mixer Kvs 4.0 and WILO PARA SC 15/6 pump 10084149

Compact pump group – an efficient solution for your heating system

This compact pump group, equipped with a mixer and an efficient WILO PARA SC 15/6 pump, is a ready-to-use solution for servicing mixing circuits in central heating systems. The device combines mixing, pumping and installation protection functions in one small module. This saves space and simplifies installation, appreciated by both installers and users.

The pump group is characterized by high energy efficiency thanks to the use of a 3-part EPP insulation, compliant with German GEG regulations regarding energy saving. The insulation minimizes heat loss, which translates into lower operating costs. The design has been thought out in terms of easy installation – the whole thing is mounted with a single screw, and the hidden cable routing on the back of the insulation ensures an aesthetic appearance of the installation. The set includes a wall bracket and mounting elements, which further facilitate installation.

Advantages and functionality:

• Compact dimensions: Allow installation in limited space – ideal for modernizing existing installations or new projects with limited surface area.
• High energy efficiency: EPP insulation minimizes heat loss and reduces heating costs.
• Easy installation: Simple construction and dedicated mounting elements shorten installation time and reduce labor costs.
• Versatility: The ability to switch the power supply back increases flexibility in use in different installation configurations.
• Integrated protections: Shut-off valve with check valve and thermometer on the supply ensure safe and reliable system operation.
• Two sensor connections: Allow precise temperature control and optimization of the heating system operation.
• Efficient WILO PARA SC 15/6 pump: Provides adequate water flow in the heating system, guaranteeing thermal comfort.

The HKM20 pump group is designed to work with installations with a nominal diameter of DN20, and its maximum working pressure is 6 bar. The device works perfectly in systems with an operating temperature from +2°C to +90°C. The recommended range of application with ΔT=20 K is a maximum of 24 kW for a mixer with kvs=4.0 and 48 kW for a mixer with kvs=6.3 – making it a suitable choice for both smaller and larger heating installations. All connections are made in a 1"M standard with a flat seal, which ensures tightness and easy connection to the existing installation.
