The Hydratron HP Series Liquid Pump is a Hand Powered spring-return reciprocating, positive displacement pump designed to generate High Static Liquid Pressures in a closed system where no other power source is required. The pressure increase is made possible by means of the area ratio between the larger diameter hand-drive piston directly connected to a smaller diameter liquid plunger. These pumps are typically used when smaller volumes are to be pressure tested or actuated and the user prefers a “hand-lever” feel to the application or when no air power is available. Normally used with water or oil, many other fluids can be pumped depending on seal material options used. All Models can easily be incorporated into easy to operate Standard System hydraulic power units.
