Up to NEMA 5013 Frame / 600 HP / 2, 4, 6 Pole
ABB pump motors are three-phase, cast iron NEMA motors designed for pumping duty: LP100 and HP100 vertical solid shaft motors for in-line, booster and vertical turbine pumps, and the DP200 HPS for horizontal multi-stage pump systems. All are NEMA Premium® efficient.
Like the rest of the ABB NEMA range, these pump motors came to ABB with the Siemens low voltage NEMA motor business in 2023 and continue under the ABB name. Each is built around the load a particular pump puts on the motor, in particular how much axial thrust the motor bearings have to carry.
The LP100 and HP100 are designed to IEEE 841-2021. For close-coupled or end-suction pumps that don’t need a dedicated pump motor, a C-face general purpose motor is usually the better fit.

A vertical P-base motor mounts on top of the pump through a machined P-flange base, with the shaft pointing down into the pump. Its thrust bearing carries the axial load from the pump, so the motor is chosen by thrust rating as well as horsepower. The ABB LP100 and HP100 are both P-base motors with a solid shaft that couples to the pump shaft below the motor.
Thrust. Both are vertical solid shaft P-base motors from 3 to 250 HP, designed to IEEE 841-2021. The HP100 is a normal thrust motor for pumps that carry most of their own axial load. The LP100 is a high or extra high thrust motor, with up to 175% more thrust capacity than a conventional design, for in-line and booster pumps. API 610 compliance, a non-reverse ratchet, ceramic drive-end bearings and bearing isolators are options on the LP100.
Use the down-thrust and up-thrust figures from the pump manufacturer. Normal thrust (HP100) suits pumps that carry most of their own axial load. High or extra high thrust (LP100) suits pumps where the motor bearings take the impeller weight and hydraulic thrust.
It stops the motor and pump turning backwards when the pump stops and water drains back down the column. Backspin can damage the motor and loosen line shaft couplings, so a ratchet is common on vertical turbine pumps. It is available as an option on the ABB LP100.
Yes. The LP100, HP100 and DP200 HPS are built for inverter use to NEMA MG1 Part 31, with a 20:1 speed range on variable torque loads such as centrifugal pumps.
NEMA motors are designed for 60 Hz supplies. Some ratings carry a dual 60/50 Hz nameplate, but output, speed and voltage at 50 Hz differ from the 60 Hz rating, and pump output changes with speed. Check the datasheet for the specific motor and supply.
