Taco 1612D Stainless Steel In-Line Pump 1/2HP 3PH 1.5″ Flange
Description
Taco 1612D Stainless Steel 1/2HP 3PH
The Taco 1612D 1/2HP 3PH combines the corrosion resistance of a stainless steel volute with the reliability of a three-phase industrial drive. Its 1.5-inch flanged mechanical interface is designed for high-volume open-loop systems. The internal geometry is optimized for high-velocity fluid displacement, utilizing a stainless steel shaft sleeve to protect the motor shaft from the aggressive nature of hot, aerated water. This model is the mechanical standard for large commercial laundry, healthcare, and hospitality facilities requiring 24/7 water circulation.
Equipped with a 1/2HP three-phase motor, this 1612D variant provides exceptional electrical efficiency and balanced power consumption across 208-230/460V lines. Three-phase operation eliminates the mechanical stresses of starting capacitors, providing a smoother ramp-up to 1750 RPM. This stable electrical configuration minimizes vibration harmonics, which protects the precision-ground ceramic seal faces and high-load bearings, resulting in a significantly longer service life compared to single-phase alternatives.
