4 Product description

The product is a pre-assembled, tightness-tested and heat-insulated pump assembly.

The universal insulation allows for the installation of virtually any standard circulation pump (with G1^1/2 connection and a length of 180 mm) without major reworking of the insulation.

The second ball valve in the return line lets you replace the pump without draining the system.

In addition, the system is modular so that the flow line can be mounted at the left or the right side. Optional temperature probes 6mm can be mounted to all ball valves.
