Description

The Prime Line SP, SPM, and SPH Series self-priming centrifugal pumps are engineered to deliver reliable performance across a wide range of water-moving applications. A built-in check valve helps the pump retain enough liquid for fast priming and automatic repriming after the initial startup—an advantage when suction conditions are inconsistent.

The enclosed, silicon-bronze impeller and replaceable wear ring provide high efficiency and long-term durability, while the cast-iron casing uses a back pull-out design for easier service. With stainless-steel shaft protection and a dependable carbon-ceramic mechanical seal, these pumps are built to handle frequent use season after season.

PRODUCT FEATURES

• Self-priming capability: A replaceable check valve holds liquid in the casing to ensure rapid priming and automatic repriming if suction is interrupted.

• High-efficiency impeller system: Silicon-bronze enclosed impeller, precision balanced and keyed to the shaft; replaceable wear rings extend pump life and maintain performance.

• Durable casing and diffuser: Cast-iron construction with a back pull-out design and dedicated fill and drain ports for quick startup and end-of-season service.

• Stainless shaft sleeve: 300-series stainless-steel sleeve protects the motor shaft from wear and corrosion.

• Reliable mechanical seal: Carbon-ceramic sealing faces with BUNA elastomers and stainless-steel hardware.
