Generating an incredible 37 gallons per minute of coolant circulation this CSR electric pump gives you the flow you need without costing you horsepower. CNC-machined from T-6 aluminum the lightweight (5 1/2 lbs.) pump has a direct drive 12V motor spinning a redesigned impeller on a stainless steel shaft. A CSR pump draws just 5.8 amps and because it doesn run off of your crank it won eat up race-winning horsepower. Accepts a 3/4 in. NPT water inlet (not included). Depth (nose to rear): 6.0 in. Depth (Back plate to block): 1.5 in. Weight: 5.5 lbs.

Other features include:
# Pump motor designed and made in the USA.
# High quality, carbon-ceramic mechanical seal.
# Sophisticated, super efficient impeller designed using CAD technology.
# Pump motor magnets are held in place by a patented spring retainer, not glue.
# Pump motor incorporates a sophisticated electronic R/F reduction system to eliminate ignition interference.
# Incorporates all o-ring assembly- no gaskets or silicone.
# Anodized inside and out for long lasting corrosion protection.
# Pump shaft is made of stainless steel, which eliminates corrosion.
# Removable center section for ease of cam and timing modifications.
# Removable center section whichs allows the pump to operate on different engines, just purchase the appropriate flanges.Generating an incredible 37 gallons per minute of coolant circulation this CSR electric pump gives you the flow you need without costing you horsepower.
