OEM Technologies 90026 3100 PSI 2.4 GPM Vertical Axial Cam and 90028 3300 PSI 2.4 GPM Horizontal Axial Cam Replacement Pressure Washer Pump Kits

The OEM Technologies 90026 vertical axial cam and 90028 horizontal axial cam replacement pressure washer pump kits complement each other by offering compatible pumps for both vertical and horizontal shaft gas pressure washers. The 90026 pump produces up to 3100 PSI at 2.4 GPM and is designed for vertical shaft gas pressure washers with a 7/8" diameter shaft, like the Honda GCV160/170 engines. It features stainless steel pistons for improved seal life. The 90028 pump also delivers up to 2.4 GPM, but at a higher 3300 PSI maximum pressure. This pump is made for horizontal shaft gas pressure washer engines with a 3/4" diameter shaft, compatible with the Kohler SH270 and Honda GC160/190 engines. Like the 90026, it has stainless steel pistons. Both easy-to-install pump kits use standard garden hose inlets and threaded M22 high pressure hose outlets, compatible with hoses like the Simpson MorFlex models 40224-40226 and Santoprene 41182. Their maintenance-free crankcases never need oil changes. Thermal relief valves protect the pumps from overheating in bypass mode for extended durability. With their comparable flow rates and complementary engine mount designs, these axial cam replacement pump kits let you revive either vertical or horizontal shaft gas pressure washers.

• Replace worn pumps easily with these OEM axial cam pump kits that produce up to 3300 PSI at 2.4 GPM to clean surfaces with pressure washers.
• Universal SAE bolt patterns and standard garden hose/M22 connections fit many residential and industrial gas pressure washers with vertical or horizontal engines.
• Maintenance-free, anodized aluminum crankcases withstand corrosion; thermal relief valves prevent overheating damage during bypass.
• Compatible with Simpson MorFlex hoses (40224, 40225, 40226) and Santoprene hose 41182 to optimize cleaning accessory performance.
• Ideal for replacing pumps on aging pressure washers instead of buying new machines, saving time and money.
