The General Pump T991 is a T Series 50 triplex plunger pump that is mainly designed for high-pressure washing applications and general cleaning applications.
The T991 triplex plunger pump has unitized stainless steel K01 inlet and outlet valves, solid ceramic plungers with constantly lubricated packings, a forged brass manifold, and a standard 24mm solid shaft for mounting to pulleys. Flex coupling and bell housing are available for direct drive to provide you with easy assembly and reliability. The oil-bath crankcase has die cast, anodized aluminum construction and a 15.2 ounce capacity.
Note: For lubrication, you must fill the crankcase to the very top of the oil gauge window with non-detergent SAE 30W oil. Change the oil after a 40 hr. break-in-period, and then every 3 months or 500 hr. intervals afterward.
Specifications: This 19 lb. pressure washer pump has a maximum fluid temperature of 165 degrees F, a maximum inlet vacuum of 9' water, and 3.6 / 3.0 EBHP horsepower (depends on volume and pressure).
