Grundfos UPS3 15-50/65 Domestic Heating Circulating Pump

A high efficiency canned-rotor circulator, designed for circulating liquids in domestic heating systems - Suitable as a stand-alone or integrated circulator pump in existing systems as a replacement or in new heating systems.

Features:

• The UPS3 combines increased energy efficiency, an easy to wire plug and on board diagnostics.
• Very reliable due to ceramic bearings and shafts, a manual deblocking port and robust start-up functionality.
• Higher efficiency at EEI =0.20 which is the benchmark for the most efficient circulators.
• Underfloor heating mode - 2 constant pressure settings.
• Installer power plug - No opening of control box required.
• Alarm indication - for easy fault diagnosis.
• Extra performance - Up to 6.5mtr head.
• Automatic and manual de-blocking - Robust start-up function.
• The pump features three control modes - 1) Constant pressure control with two setting, 2) Proportional pressure control with two settings, 3) Constant curve mode with three settings.
• Easy and user-friendly one-button interface makes replacement and settings simple and fast.
• LEDs indicate the actual operating status as well as warnings and alarms.
• Long life ensured buy innovative design and high quality materials used in construction.
• The pump is self-venting through the system, which contributes to easy commissioning.
• The compact design, featuring a pump head with an integrated control box, fits into most common installations, as well as boilers, due to the ambient temperature range.
• Maintenance-free operation due to pump and motor forming an integral unit without a shaft seal. As well as the bearings being lubricated by the pumped liquid.
• Servicing screw accessible from the front allows for easy access to the pump shaft if necessary to deblock the pump once installed.
• The pump housing is made of cast iron which is electrocoated to improve corrosion resistance.
• The motor is a synchronous permanent-magnet motor characterised by high efficiency.
• The pump speed is controlled by an integrated frequency converter incorporated in the control box.
