The Gorman-Rupp PMB (Pump Motor Base) Series is a ready-to-go pumping solution. These plug-and-play pump sets combine trusted self-priming or priming-assisted Gorman-Rupp pumps with premium electric motors, ideal for a wide range of industrial and municipal applications.
Thanks to its modular design and solid base construction, the PMB system offers simple setup, reliable performance, and long-term durability. The rigid, fully galvanized baseplate provides extra stability. A removable high-visibility safety guard around the coupling makes maintenance safer and easier.
With fast availability from Gorman-Rupp’s European inventory, you’ll reduce downtime and keep your operations running smoothly.
Reliable in solids-laden liquids and slurries. This self-priming centrifugal pump features automatic reprime in open systems, no need for suction or discharge check valves.
High-efficiency operation and low energy use. With a smooth volute casing and multi-vane impeller, this pump handles limited solids and maintains strong performance.
Built for high-pressure, high-flow applications. Available in 3″, 4″, and 6″ sizes. Especially suited for industrial, municipal, and wastewater use with fibrous or contaminated fluids. The optional Eradicator™ system improves handling of tough solids.

Looking for the right configuration for your application?
The PMB (Pump Motor Base) is an electrically driven, self-priming centrifugal pump set designed for stationary use. It is designed to pump clean water, dirty water, sewage, and an array of other industrial fluids. It combines a reliable Gorman-Rupp pump with a galvanized steel base and a high efficiency electric motor.
Each PMB pump set is available in three configurations: direct coupled, horizontal belt drive, and vertical belt drive. The belt drive versions allow precise speed adjustment to match application requirements.
The PMB line includes models from the Super T, Super U, and Ultra V Series — such as T2 to T10, U3 to U6, and V3 to V6 — offering a wide performance range from 48 to 870 m³/h capacity and heads up to 64 meters. PMB pump sets can also be tailor made to include models like the O-series, Rotoprime, prime assisted or standard centrifugal pumps.
Gorman-Rupp PMB pumps are built from high-quality materials including cast iron, ductile iron, duplex stainless steel (CD4MCu), and high chrome alloys, ensuring long life and wear resistance even in demanding applications.
Yes. The PMB series is designed for handling sewage, sludge, and fibrous wastewater. Models equipped with the Eradicator or Eradicator Plus wear plate reduce clogging and improve performance in solids-laden fluids.
Yes. All PMB pump sets are fitted with IEC induction motors that are suitable for use with variable frequency drives (VFDs) for flexible control and energy optimization.
Depending on the model, PMB pumps can handle solids up to 100 mm, making them ideal for applications such as sewage systems, industrial wastewater, and construction site dewatering.
Yes. IE4 and IE5 motors are available upon request to further increase efficiency and reduce operational costs.
PMB pumps are used in municipal wastewater, industrial processing, construction site dewatering, and general clean or dirty water transfer applications.
