Strengthen Your Marine Maintenance Routine with the JPR-SC50IF JMP Marine Scania Cooling Pump

April 1, 2026

When it comes to marine maintenance, few systems are as critical as your engine’s cooling system. For vessels powered by Scania DI09, DI12, DI13, and DI16 series engines, maintaining proper seawater flow is essential to preventing overheating and ensuring long-term engine reliability. The JPR-SC50IF JMP Marine Scania Replacement Engine Cooling Raw Water Pump delivers the high-volume performance and durability needed to support demanding marine operations.

Whether you're performing routine marine maintenance or replacing a worn OEM pump, the JPR-SC50IF provides a dependable, direct-fit solution. Designed to replace Scania pump part numbers 1785016 and 1785018, as well as Johnson models 10-24308-01 (F9B-9) and 10-24308-02 (F9B-905), this pump offers marine technicians a reliable upgrade built for long-term service.

Engineered for Marine Performance & Heavy-Duty Durability

Every component of the JPR-SC50IF is built to meet the demands of real-world marine maintenance. Designed for high-output engines, this pump combines rugged construction with advanced internal improvements to deliver consistent cooling performance.

Key features include:

• Strong bronze body with heavy-duty marine-grade casting, providing superior corrosion resistance in harsh marine environments
• Marine-grade 3X series non-magnetic shaft, engineered for durability and long-term wear resistance
• High-performance flexible impeller (JMP 8301-01K), ensuring powerful and consistent seawater flow
• Forged cam design, enhancing strength under continuous operation
• High-volume flow capacity and fast flow rate, ideal for large displacement engines

With a 2" flange port connection and a weight of approximately 18 lbs (8.18 kg), the JPR-SC50IF is built for serious marine applications where performance and reliability are non-negotiable.

Designed for Preventive Marine Maintenance

Effective marine maintenance is about preventing failures before they happen. The JPR-SC50IF supports this proactive approach with improved internal design and service-friendly features.

Unlike traditional designs, this pump utilizes an O-ring end cover packing instead of a paper gasket, providing a more reliable seal and simplifying routine maintenance. The pump also features a machined flat wear plate surface, improving internal efficiency and reducing wear over time.

Service support includes:

• Major Service Kit (JSK0028) – complete internal components for full rebuilds
• Minor Service Kit (JSM0033) – ideal for routine maintenance and quick servicing

While not internally interchangeable with genuine OEM components, JMP Marine has implemented key design upgrades to improve durability, efficiency, and long-term performance.

Advanced Design Improvements Over OEM

The JPR-SC50IF incorporates several enhancements that directly benefit marine maintenance routines:

• Thicker pump housing (5mm vs 3mm) for added strength
• Improved drain design for more efficient water flow
• Enhanced cam design for better performance
• Marine-grade stainless steel shaft for superior durability
• O-ring sealing system replacing traditional gasket design

These improvements contribute to longer service intervals and more reliable operation in demanding marine environments.

Dependable Cooling for High-Performance Marine Engines

From commercial vessels to heavy-duty marine applications, the JPR-SC50IF ensures stable and efficient cooling performance where it matters most. By maintaining proper seawater circulation, this pump helps protect engine components, reduce downtime, and improve overall vessel efficiency.

As part of a proactive marine maintenance strategy, upgrading to a high-quality cooling pump like the JPR-SC50IF can significantly enhance reliability and long-term performance.
