Grundfos Alpha 15-55F/LC Circulator Pump (59896832) is a variable speed circulator with a built-in check valve and Line Cord. With its permanent magnet motor design, this energy efficient circulator reduces power consumption by 50% or more. The unique patented AUTOADAPT feature of the Grundfos 15-55F/LC model controls pump performance automatically within defined performance range, ensuring lowest possible energy consumption without sacrificing comfort. Conveniently installed line cord allows to plug the circulator right into the electrical outlet, bypassing unnecessary wiring.
Grundfos 1/6 HP 115V Circulating Pump Cast Iron Body
The Grundfos UP26-120 U is a cast iron circulator pump for closed circulation of water. The Grundfos model utilizes a two-pole, single phase motor at 1/6 (0.16) HP and produces a flow range of 0-19 GPM and a head range of 0-38 ft. The Grundfos UP26-120 U circulator pump functions at 115V, 2.15 Amp, and 60Hz, and has a maximum pressure of 145 PSI. The optimal water temperature for this Grundfos circulator pump model is within the 32-203 F range.
The Grundfos UP26-120 U circulator pump utilizes a 1-1/4 inch union connection.
The AutoFill™ automatic filling valve is a pressure reducing valve with
a compensating seat, an inlet filter, a shut-off valve and a check valve.
It is installed on the water inlet piping in sealed heating systems, and
its main function is to maintain the pressure of the system to a preset
value, automatically filling up with water as required. This valve has been
designed as pre-adjustable, which means it can be adjusted at the required
pressure value before charging the system. After installation, during the
filling or topping-off phase, the water feed will stop automatically when the
set pressure is reached. There are no levers to flip or valve to close. Preassembled with the backflow preventer, it features an atmospheric vent
which is designed to protect drinking water systems from return flow, caused
by back-siphoning or backpressure, of contaminated fluids. The 573 series
has been specifically certified to standards CSA B64.3 and ASSE 1012.
