The PAW K32 - 1" low temperature pump module is designed to replace traditional injection mixing systems. When used for closed loop hydronic designs in conjunction with an electronic control system and a PAW SR10 direct drive mixing actuator, the radiant heating circuit receives proper heating temperatures by injecting proportional amounts of hot boiler water in conjunction with lower temperature return circuit water.
Upper supply and return lines are 1" NPT female thread. Bottom supply return lines are 1-1/2" male flat faced union connections for use with PAW - MV series distribution manifolds.
Supplied as standard with a 2-bolt flanged 115 volt Wilo Star21FX 3-Speed circulator.
Models supplied without circulator are available as an option.
