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.
