Caleffi HydroMixer Injection Pump Mixing Unit with Insulation - Dual Line with UPS15-58 Pump on Right - 165600A.  This unit does not have a mixing valve - look at the 166 or 167 HydroMixer series for this.

The Caleffi HydroMixer 165600A provides high temperature flow direct to secondary heating circuits, complete with onboard Grundfos UPS15-58 three-speed, supply and return temperature gauges, secondary circuit shut-off ball valves and pre-formed insulation shell.

The unit can be ordered with supply flow and pump on the right side, and the unit is field reversible to accommodate changing installation requirements.

The adjustable differential pressure by-pass valve 519600 and wall bracket code 165001 are optional. The unit comes with male union connections which require separately purchased, 1 inch sweat or 1 inch NPT, top outlet or bottom inlet fitting kits

Fitting sets sold separately - see to the right on this page.
