M-332 Marine Flexible Impeller 

The M-332 Marine Flexible Impeller is a high-quality replacement part designed to deliver dependable and efficient pumping performance for a variety of marine applications. Manufactured with precision and tested to rigorous quality standards, it ensures long-lasting durability even in demanding sea conditions.

OEM-Grade Korean Marine Technology
This impeller is based on the renowned M-112 Rubber Impeller design, known for its robust build and superior flexibility. Korean marine-grade engineering ensures it can be fitted to most makes and models of bronze flexible impeller pumps used for engine cooling, bilge pumping, water transfer, and general-purpose marine pumping. Each impeller undergoes strict quality control checks to guarantee reliable performance in the harshest environments.

High-Performance Design and Dimensions

• Length: 95 mm

• Width: 63 mm

• Number of Blades: 10

• Drive Type: Double Flat Drive

The multi-blade flexible construction ensures optimal fluid movement, creating a strong suction and steady flow rate. Its design minimizes wear on the pump chamber, extending both pump and impeller lifespan.

Material Selection for Maximum Efficiency
For engine cooling and fresh/saltwater transfer, neoprene impellers are recommended. Neoprene offers excellent resistance to seawater and mild fuel traces, making it ideal for clean water systems.
For bilge and contaminated water pumping, nitrile impellers are preferable due to their resistance to oil and diesel contamination. Choosing the right material ensures optimal operation and prevents premature wear.

Maintenance and Replacement
To maintain peak performance, it is recommended to replace the impeller at least once per year—or sooner for vessels in heavy use. While some impellers may last multiple seasons if installed and maintained correctly, preventive replacement helps avoid costly breakdowns.

Replacement Tips:

• Remove the impeller by unscrewing the end cover screws and gripping the hub with an impeller removal tool or channel lock pliers.

• Avoid using screwdrivers as they can damage the pump body and cause leaks.

• Keep a spare impeller onboard for emergencies, as the cooling impeller is a critical component of your engine’s operation.
