Grundfos UPM3 Auto Pump

Description

Grundfos UPM3 AUTO 25 /70 130 mm 52 watt is the ideal answer for Underfloor Heating Systems. The Grundfos UPM3 Auto is for all applications in which an internally controlled pump is needed. It is designed to be used in appliances or cabinets with increased ambient temperatures and limited space options.

130 mm length, 7 m head pump

Connections 130mm x 11/2″ BSP Thread ~ n.b. BSP sizes don’t match up with what you measure on the scale of a ruler  (11/2 Inch BSP =47.80 mm)

The pump has 3 control modes and 10 curves; proportional pressure (3), constant pressure (3) and constant curve (4).

The pump is ideal for replacing the Alpha2L but does not feature Auto Adapt.
