The RIVA/Solas Stainless Steel Race Pumps deliver increased acceleration and top speed along with reduced cavitation, for high performance applications that exceed the limits of original pump efficiency. Each features a computer designed 160mm / 12-vane stator section — far more efficient than the stock 155mm / 8-vane pump — constructed of high grade stainless steel for superior strength and corrosion resistance.
