Grundfos UP 15/14BU 1PH HWS Pump no fittings
UP 15-14 BU 80
The pump is equipped with a spherical motor. In contradistinction to the conventional canned-rotor motors, the spherical motor does not have a rotating bearing shaft. The stator transfers the magnetic field to the rotor in the water-conducting part of the pump. The pump is only suitable for pressurised hot water systems.
The water-conducting part of the pump is hermetically separated from the stator with a stainless steel spherical separator.

The built-in timer enables the pump to start and stop automatically at set intervals of minimum 20 minutes.

The pump is characterized by:
* Self-adjusting, gimbal-mounted rotor bearing lubricated by the pumped liquid.
* High-quality bearing material.
* The motor can be separated from the pump housing, enabling easy maintenance and replacement.
* Corrosion-resistant impeller, Stainless steel, EPDM, PPO, PTFE, Graphit.
* Brass pump housing.


The motor is a single-phase motor. It does not require external motor protection.
