TECPOS Hydraulic Hand Pumps

Hydraulic hand pumps deliver high-pressure fluid flow to the hand pump outlet. Hydraulic hand pumps are powered by mechanical energy sources to pressurize fluid. A hydraulic hand pump, when powered by pressurized fluid, can rotate in a reverse direction and act as a motor. Operating specifications, housing materials, and features are all important specifications to consider when searching for hydraulic hand pumps.
hand pump type and hand pump stages are the most important operating specifications to consider when searching for hydraulic hand pumps. Choices for hydraulic hand pumps types include axial piston, radial piston, internal gear, external gear, and vane. An axial piston hand pump uses an axially-mounted piston to pressurize fluid. Mechanical motion from the hand pump's power source moves the piston through a chamber, pressurizing the fluid it comes in contact with. A radial piston hand pump uses pistons mounted radially about a central axis to pressurize fluid. An alternate-form radial piston motor uses multiple interconnected pistons, usually in a star pattern. The hydraulic hand pumps¡¯ power source causes the pistons to move, forcing the pistons through the chambers and pressurizing fluid. An internal gear hand pump uses internal gears to pressurize fluid. The hand pump's power source causes the internal gears to turn, which forces fluid through the hand pump outlet. An external gear hand pump uses external gears to pressurize fluid.
The hand pump's power source causes external gears to turn, which forces fluid through the hand pump outlet. A vane hand pump uses a vane to pressurize fluid. The hand pump's power source causes the vane to rotate. As the vane rotates, blades on the vane push fluid out the hand pump's outlet. hand pump stages include single stage, double stage, triple stage, and four or more hand pump stages.
Additional operating specifications to consider for hydraulic hand pumps include continuous operating pressure, maximum operating pressure, operating speed, operating horsepower, operating temperature, maximum fluid flow, maximum fluid viscosity, displacement per revolution, and hand pump weight. The continuous operating pressure is the maximum pressure available at the hand pump outlet. The maximum operating pressure refers to the maximum peak pressure available at the hand pump outlet on a noncontiguous (intermittent) basis. The operating speed is the speed at which the hand pump¡¯s moving parts rotate is expressed in revolutions per minute, or similar terms. The operating horsepower is the amount of power the hand pump is capable of delivering. Horsepower is dependent on the pressure and flow of the fluid through the hand pump. The operating temperature is the fluid temperature range the hand pump can accommodate. Maximum and minimum fluid temperature is dependent upon internal component materials, and varies greatly between manufacturer The maximum volumetric flow through the hand pump is expressed in terms of gallons per minute, or similar units. The maximum fluid viscosity the hydraulic hand pump can accommodate is a measure of the fluid's resistance to shear, and is measured in centipoise. Centipoise is a common metric unit of dynamic viscosity equal to 0.01 poise or 1 millipascal second. The dynamic viscosity of water at 20 degrees C is about 1 centipoise. The correct unit is cP, but cPs and cPo are sometimes used. The fluid volume displaced per revolution of the hand pump is measured in cubic centimeters (cc) per revolution, or similar units. The weight of the hydraulic hand pump is measured in pounds or similar units.
