Detailed Information

Description

LK HydronicGroup H/C 125 DN 25 is a complete pump group that is suitable for heating and cooling where direct supply or mixed supply is desirable. Consists of a highly efficient circulation pump, insulation, and two ball valves with thermo­meter, on the return side there is an integrated check valve. Cataphoresis-treated pipe to resist corrosion. When installing LK HydronicGroup H/C 125 DN 25 Cooling onto the LK 860 H/C 125 DN 25 manifold, the mounting kit (part no. 095515) should be used to prevent condensation. Insulation is only suitable for Wilo Para 6 and 8 meter.

LK 860 H/C 125 DN 25
Cataphoresis-treated manifold available with or without hydraulic separator for one, two, three optionally four pump groups.

LK 861 H/C 125 DN 25
Pump group that is suitable for heating and cooling where direct supply direct supply is desired.

LK 862 H/C 125 DN 25
Pump group that is suitable for heating and cooling where mixed supply is desired, a three-way mixing valve is included. For cooling applications, LK 862 H/C 125 DN 25 must be supplemented with actuator, LK 950 or LK SmartComfort, so condensation does not leak into the insulation and forms frost. Insulation is only suitable for Wilo Para 6 and 8 meter.
