2,400 PSI triplex plunger pumps in two different mounting configurations. This pump is for vertical gas engine driven units. Please reference the pictures below showing the mounting difference between the two models. Specifications: 2.2 GPM at 2,400 PSI and spins at 3,400 RPM. This pump mounts directly on to the engine shaft by using a keyed hollow shaft connection system. The mounting flange provides a convenient connection to most 7/8” diameter shaft vertical gas engines in 4 - 7 HP (reference the cc to HP chart) and fits most OEM carts. The pump includes a built-in pressure control valve, downstream chemical injection system, EZ start valve and thermal relief valve.
