MAGdrive
Magnets are used to drive the shaft and impellers in this product group within the CR product family.
Main pumps
In heating and air conditioning systems, water must be distributed from the supply system to the point of consumption.
Maintenance and repair costs (Cm)
The calculation of the life cycle cost of a pump system includes the total cost of maintaining and repairing the system over its lifetime.
Manhole
A manhole is a chamber built on a sewer pipe or conduit usually just large enough for one person to enter.
Manometer
A manometer is an instrument that is used for monitoring current pressure in a heating or cooling system at a given location.
Mean temperature difference
The average temperature difference specifies the average difference between the flow and return temperature over a given period of time.
Mixing loop
Heating systems with various heat consumers and zones have varied demands for flow and temperature.
Mixing loop, double shunt with 3-way valve, type 1
A double shunt mixing loop is characterised with constant flow on the primary side which is causing high pumping energy costs. A double shunt mixing loop is normally fitted with a 3-way valve.
Mixing loop, double shunt with 3-way valve, type 2
A double shunt mixing loop is characterised with constant flow on the primary side which is causing high pumping energy costs.
Mixing loop, single shunt with 2-way valve
A single shunt mixing loop is used when variable flow or variable temperature or both are desired on the secondary side.
