Technical data
Technical data
PM 1
1) The start pressure of PM 1 (p
start
) depends on the variant.
See nameplate.
2) IP65 applies to the PM 1 unit. IP44 applies to the plug connection on
the cables.
3) The power of PM 1 is calculated with cos ϕ
= 0.9.
4) Net weight of PM 1 is the weight of the unit without cable or plug.
Note: The technical data may be limited by the pump data.
See installation and operating instructions for the pump.
PM 2
1) The start pressure of PM 2 (p
start
) can be set in steps of 0.5 bar.
2) The stop pressure of PM 2 (p
stop
) is only used in systems with
a pressure tank.
3) IP65 applies to the PM 2 unit. IP44 applies to the plug connection on
the cables.
4) The power of PM 2 is calculated with cos ϕ
= 0.9.
5) Net weight of PM 2 is the weight of the unit without cable or plug.
Note: The technical data may be limited by the pump data.
See installation and operating instructions for the pump.
