Technical specifications


The Grundfos UPS 25-100 is a single phase pump specifically designed for central heating systems.
The motor is an asynchronous squirrel-cage motor in conformity with the EMC directive.
Standards used: EN 61 000-6-2 and EN 61 000-6-3.
The terminal box and the motor-pump unit have been wet-tested to EN 60 335-1: 1994 and EN 60 335-2-51: 1997.
The terminal box is easily accessible and has functional cable connecting terminals. The cable entry is tight and has a built-in cable relief. The cable entry of singlephase
motors can be pushed out of its guide to facilitate the correct fitting of the cable.
The motor incorporates thermal overload or impedance protection. Therefore, no external motor protection is required.

Pumped liquids
Depending on type, Grundfoscirculator pumps are designed for the following liquids:
- thin, clean, non-aggressive and non-explosive liquids without solid particles or fibres
- cooling liquids, not containing mineral oil domestic hot water softened water.
If the circulator pump is used for a liquid with a viscosity higher than water, the hydraulic performance of the pump will be reduced. When selecting a pump, the viscosity of the pumped liquid should be taken into consideration.

Maximum system pressure
Pump with unions (PN 10): 1.0 MPa (10 bar)
