ABB Vertical Hollow Shaft Motors Deliver Deep-Well Pump Performance
ABB’s new vertical hollow shaft (VHS) motors are built for vertical turbine pump applications where performance, reliability and longevity are critical. The line reflects ABB’s commitment to innovation, energy efficiency and customer-centric engineering.
ABB VHS motors reduce downtime with a top-mounted coupling and hollow shaft that provide quick, direct access to the pump shaft. This design simplifies work for operators, making routine service faster and easier.
VHS motors offer NEMA Premium (IE3) efficiency, high-thrust capability and drop-in design compatibility, filling a critical market need for durable, low-maintenance solutions in water, agriculture and industrial pumping systems.
With a compact, robust design, VHS motors deliver smooth power transmission, require minimal upkeep and offer extended service life in harsh environments.
“ABB vertical hollow shaft motors are purpose-built to elevate operations across multiple industries,” said Terry Bell, ABB product manager. “From irrigation systems to municipal water supply, these motors offer unmatched reliability and performance, helping customers reduce maintenance and overall operational cost.”
ABB VHS motors use heavy-duty, extra high-thrust bearings designed to withstand the intense axial loads of deep-well and vertical-turbine pumps.
Designed to match industry-standard dimensions, ABB VHS motors provide a true drop-in fit, cutting installation time for new builds and motor replacements.
Key features include:
• NEMA Premium (IE3) efficiency: Delivers consistent torque and energy savings
• High-thrust capacity: Provides 175 percent extra thrust on 360 frames and above; double-stacked bearings on 440 frames and above
• Stationary and non-reverse ratchet: Prevents reversing due to backspins
• Standard NEMA P-base flange: Allows easy drop-in replacement of existing motors
• Inverter duty rated: Supports modern variable speed drives
• User-friendly design: Top-mounted coupling for shaft and impeller access, plus oversized conduit box and sight glass
• Durable construction: Heavy-duty cast iron frame; UL Listed and Weather Protected Type 1 (WP1) ratings
• Wide range of configurations: Available in 15 to 500 horsepower with multiple voltage and frame options
Applications include:
• Deep-well vertical turbine pumps
• Agricultural irrigation systems
• Municipal water and wastewater systems
• Industrial cooling towers
• Fire protection systems
