Now supplied as the Grundfos PM PLUS (93264956)
The PM1 22 (96848701) is discontinued. Orders placed against this listing are supplied as the Grundfos PM PLUS 93264956, the factory direct replacement, with the same G 1″ male inlet and outlet. The dimensions of the PM PLUS are different to the PM1, so allow additional clearance when replacing one in a tight enclosure or pump cabinet. Cut-in is selectable at 1.5, 2, 2.5 or 3 bar — the PM1’s fixed 2.2 bar setting is not offered, so set the nearest step to suit the installation.

The Grundfos PM PLUS is an automatic pressure manager for the Grundfos JP5 and JP6 booster pumps, CM pumps and SQ 3″ borehole pumps, and for any other single-phase water supply pump within its electrical limits. It starts the pump when system pressure falls to the selected cut-in point and keeps it running for as long as there is flow.

Compared with the PM1 it adds a selectable start pressure, a 0–12 bar pressure gauge, a higher 10 A contact rating and a 1 bar differential setting for use with an external pressure vessel. Dry-running protection with automatic restart and the integrated non-return valve are carried over.
