December 29, 2025

When reliability, durability, and versatility matter, the JPR-40LP 1 1/2" NPT General Multi-Purpose Fluid Pump stands out as a trusted solution across marine maintenance, industrial operations, and municipal applications. Designed by JMP Marine for long-term performance, this pump delivers consistent flow, easy serviceability, and rugged construction in environments where downtime is not an option.

Whether used in marine systems, sewage treatment, industrial cleaning, or agricultural operations, the JPR-40LP is engineered to move fluids efficiently while withstanding continuous use. Its compact footprint and dependable design make it a smart choice for professionals looking to simplify maintenance while maximizing performance.

Built for Performance and Durability

At the core of the JPR-40LP is a strong bronze body, providing excellent corrosion resistance and structural integrity—especially important in marine and chemical-exposed environments. Unlike lightweight alternatives, this pump is built to handle demanding conditions while maintaining consistent output.

The pump features a marine-grade, non-magnetic stainless steel shaft (22mm) paired with a long-life mechanical seal, reducing wear and extending service intervals. At 1,800 RPM, the JPR-40LP delivers an impressive 268 liters per minute, making it suitable for high-flow applications that require dependable, steady performance.

A high-performance flexible impeller (JMP 8001-01) ensures efficient fluid movement while minimizing internal stress, contributing to longer pump life and smoother operation.

Designed for Easy Maintenance and Serviceability

Maintenance efficiency is built into the JPR-40LP’s design. The pump uses O-ring seals at the end cover instead of traditional gaskets, allowing for quicker servicing and more reliable sealing. Replacement parts are easy to access, and the JSK0006 service kit (sold separately) simplifies routine maintenance and repairs.

With a manageable weight of 12 lbs (5.40 kg) and compact dimensions, installation and servicing are straightforward—reducing labor time and operational interruptions.

A Pump That Adapts Across Industries

The JPR-40LP is truly multi-purpose. Common applications include marine systems, sewage treatment, industrial cleaning and bottling systems, agricultural operations, and public utilities. Its ability to perform reliably across sectors makes it a valuable addition to any operation that demands durability and flexibility.

Backed by JMP Marine’s reputation for quality engineering, the JPR-40LP delivers dependable performance wherever fluid transfer is critical.
