Powerful, reliable water circulation for larger heating and hot water systems.

The UPS25-150 is a three-speed circulation pump designed for moving water through heating, air-conditioning and suitable hot water circulation systems.

Suited to larger installations, it can be used in both open and closed systems, including underfloor heating, solar heating and one- or two-pipe heating arrangements.

Its canned-rotor design combines the pump and motor into a single unit without a conventional shaft seal. The bearings are lubricated by the pumped liquid, providing quiet, low-maintenance operation.

Three selectable speeds allow circulation performance to be adjusted to suit the requirements of the system.

Frequently Asked Questions

What is the UPS25-150 used for?

The UPS25-150 circulates water through larger heating and suitable hot water systems, including underfloor heating, solar heating and other circulation circuits.

Will this pump increase my shower or tap pressure?

No. This is a circulation pump, not a domestic pressure booster. For improving pressure at taps and showers, a suitable UPA pressure booster may be more appropriate.

Why does it have three speeds?

The three selectable speeds allow the pump's circulation performance to be adjusted to suit different system requirements.

Can the UPS25-150 be installed in any position?

No. The pump must always be installed with the motor shaft horizontal, regardless of whether the pipework runs vertically or horizontally.

IMPORTANT INSTALLATION WARNING: Installing the pump with the motor shaft vertical can cause extremely rapid pump failure, potentially almost immediately after startup. Correct installation orientation is essential.

Always follow the manufacturer's installation instructions and the indicated direction of water flow.
