Grundfos Circulator pump UPS 25-60 130

Grundfos UP single-speed circulator pumps are designed for heating systems, while the three-speed UPS circulator pumps are used in central and district heating system while also being suitable for mixing loops in large systems. Both pumps provide reliable and maintenance-free operation.

The pump is of the canned rotor type, i.e. pump
and motor form an integral unit without shaft
seal and with only two gaskets for sealing.
The bearings are lubricatd by the pumped liquid.
The pump has 3-step speed selector.
The pump is characterized by:
* Ceramic shaft and radial bearings.
* Carbon axial bearing.
* Stainless steel rotor can and bearing plate.
* Corrosion-resistant impeller, Composite.
* Cast iron pump housing.

The motor is a 1-phase motor.
No additional motor protection is required.
