PRW Industries 1439000 High-Flow Aluminum Water Pump Ford FE 352-428 As-Cast

The PRW Industries 1439000 is a high-performance, high-flow mechanical water pump engineered for Ford FE big block engines. Built under PRW's Performance Quotient (PQx) line, this pump delivers superior cooling capacity for street, high-performance, and racing applications alike.

Key Features:

• 35 GPM flow rate at 4,000 RPM with minimal cavitation and proportionally increased flow rates at 5,000+ RPM
• Low pressure-injected A356 aluminum alloy pump body for lightweight strength and durability
• Precision high-flow cast iron impeller with tight clearances for maximum coolant delivery
• Pressure-balanced water passages equalize flow and minimize engine hot spots at any speed
• Heavy-duty 0.75 in. diameter steel shaft with billet steel hub and shielded-seal roller ball bearings
• 5/8 in. pilot shaft diameter with a block-to-hub measurement of 7.56 in.
• Inlet diameter: 2.125 in.
• Clockwise rotation
• As-cast (natural) finish
• Aircraft industry tolerances throughout
• Back plate O-ring sealed for most applications

Equalized water flow distribution and pressure-balanced passages make this pump an excellent choice for not just racers, but also trucks, towing, and motorhome builds. Cruisers and hot rodders will appreciate the improved cooling performance at both low and high engine speeds.
