Proflow's brand new CoolMax high-volume LS water pump is engineered for maximum coolant flow and even distribution - ideal for street, strip, or any high-demand application requiring increased volume. Cast from high-strength A356-T6 aluminium, it features curved, enlarged internal passages that deliver significantly greater flow rates than factory pumps.

At its core is an anti-cavitation impeller, manufactured using a PM (Powder Metallurgy) process to ensure low inertia and optimal performance. The impeller's curved vanes improve flow while preventing cavitation. High-quality brass fittings for the heater and main outlet are included, and thanks to the 1" NPT thread, the outlet position can be configured for either the left or right-hand side, depending on your application.

Additional features include a lightweight billet aluminium pulley, billet steel hubs, leakproof seals and gaskets, and heavy-duty roller bearing assemblies designed to withstand higher torsional loads.

CoolMax Series pumps are available in your choice of natural or black finish.

Features:

• A356-T6 cast aluminium construction
• NPT Brass heater and outlet fittings
• Includes high quality anti-cavitation impeller 
• Larger internal passages to significantly improve volume flow rates
• Lightweight billet aluminium pulley
• 125mm in height from mounting surface to edge of the belt surface

Note: For optimal performance and safety, we recommend applying a low strength thread locker to all bolts during final installation. All NPT ifttings will need to be sealed with a suitable thread sealant.
