LK 862 - Pump group where mixed supply is desired, a three-way

mixing valve is included.

LK 863 - Pump group where mixed supply is desired, a thermic

mixing valve is included. The LK 551 HydroMix has a thermostatic

element that regulates the supply and return to achieve the desired

supply temperature.

LK 864 - Pump group with a thermic loading valve LK 823 Ther-

moVar®. The pump group is intended to ensure both an optimal

temperature stratification in the storge tank and high return tem-

perature to the boiler, thus increasing the efficiency of the system.

LK 865 - Complete unit for hot water circulation. Consists of a

mixing valve, cross, circulation pump, insulation, connection kit

and three check valves. The LK 551 HydroMix mixing valve has a

thermostatic element that regulates the supply of both cold and

hot water to the desired temperature. The valve has an anti-scald

function that closes for incoming hot water if the cold water supply

ceases.

LK 867 - Pump group with a four way mixing valve, LK 830 Thermo-

Mix® B. The pump group has a 4-way bivalent mixing valve that is

designed for heating systems, where energy is taken from two heat-

ing units connected in series or parallel or for storage tank systems

where energy is extracted from two levels. The pump group should

be equipped with an automatic control unit to ensure that the most

favourable heat source is prioritised at all times.

LK 866 - Pump group with a four way mixing valve, LK 841 Thermo-

Mix®. The pumpgroup is designed for heating systems where a high

return temperature is required to prevent corrosion and thus extend

the life length of the heat source.
