Jabsco 1-1/4" Electric Clutch Pump – Double A-Groove Pulley – 12V – 11870-0005

The Jabsco 11870-0005 Electric Clutch Pump is a heavy-duty, belt-driven marine pump designed to provide on-demand seawater circulation for air conditioning, refrigeration, and auxiliary cooling systems. Featuring a 1-1/4 inch hose connection, double A-groove pulley, and 12-volt electric clutch, this pump delivers reliable, efficient performance while reducing unnecessary wear when the pump is not in use.

This model is ideal for vessels requiring high-flow raw water circulation with the convenience of electrically controlled engagement.

Electric Clutch – On-Demand Operation

The integrated 12V electric clutch allows the pump to engage only when water flow is required. This minimizes belt wear, reduces engine load, and extends pump life—making it ideal for marine air conditioning and cooling systems that cycle on and off.

High-Capacity 1-1/4" Flow

With 1-1/4 inch inlet and outlet ports, this pump is engineered for higher flow applications, ensuring consistent seawater delivery to HVAC systems, chillers, or heat exchangers even in demanding conditions.

Double A-Groove Pulley Design

The double A-groove pulley provides improved belt grip and torque transfer, reducing slippage and ensuring reliable operation at varying engine speeds. This design supports stable performance in continuous-duty marine environments.

Marine-Grade Construction

Built specifically for harsh marine use, the 11870-0005 features:

• Corrosion-resistant bronze pump body

• Stainless steel hardware

• Heavy-duty bearings and seals

• Proven Jabsco impeller technology

These components ensure long service life in saltwater applications.

Serviceable & Compatible Design

The pump is designed for easy maintenance with replaceable impellers and service kits readily available. It is commonly used as an OEM or replacement pump in marine HVAC and cooling systems.
