Grundfos UP20-30N-150 Circulator Pump

A stainless steel pump housing ensures the supply of contamination-free hot water and ceramic bearings offer extremely long life and near silent operation.

Standard Electrical Supply is 240V 1ph for all models, with each single phase model complete with internal motor protection by either thermal overload or impedance protection and can be connected to a switched/fused supply instead of a starter, three phase models are also available for a select range of UPN pumps.

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 is characterized by:

• Ceramic shaft and radial bearings.
• Carbon axial bearing.
• Stainless steel rotor can and bearing plate.
• Corrosion-resistant impeller, Composite, PES/PP.
• Stainless steel pump housing
