Vertical Hollow Shaft – WPI

Premium Efficient Motors for Turbine Pump Applications
WorldWide Electric’s Premium Efficient Vertical Hollow Shaft Motors (WPEVHS) are designed for use in turbine pump applications, including irrigation, energy generation, mining, municipal water, and chemical applications. Ideally suited for use with inverters or soft starts, WPEVHS Series motors are the smart solution for both standard and high-thrust installations. Backed by a two-year warranty, these durable motors feature outer epoxy corrosion-resistant paint, epoxy-coated rotor and windings, and a felt end bell seal to protect from pump seal failure.
