Hydraulic pumps come in different forms to accommodate a range of application requirements, from industrial die presses to heavy-duty off road equipment. One hydraulic system can vary greatly from another. For one system, a hydraulic piston pump may be the best solution, while a hydraulic gear pump may be better suited for a different one.

Powered by a hydraulic drive, a piston pump has a reciprocating positive displacement design to manage fluid flow. Pistons, or cylindrical elements within a cylinder block, create a vacuum, generated by a drive mechanism, that draws in fluid. The cylindrical chamber is pressurised by distributing energy into the fluid, compressing and forcing it towards the pump’s outlet.

Basic designs can generate about 4,000 psi, but pumps with up to 14,500 psi operating pressure are available. There are many different models that can displace a specific amount of fluid. Some allow you to adjust the displacement per revolution, which can make them more energy efficient. Piston pumps are relatively complex in design and expensive, but practical in energy-efficient applications that require high pressures and effective oil flow control.

A hydraulic gear pump is a lower-cost option, but it is quite durable, with many options available. The typical pressure rating is about 3,000 psi, but many displacement sizes and pressures can be found. Some gear pumps are rated as high as 4,500 psi, although additional valves will be needed in systems that require regular flow adjustments.

Gear pumps function by drawing fluid between their meshing gears. The adjacent gear teeth form chambers that are enclosed within the housing and pressure plates. A partial vacuum forms at the inlet where the gear teeth unmesh, allowing fluid to fill the space and be moved along the outer edge of the gears; as the gear teeth mesh again, fluid is forced out of the pump.

Both pumps use hydraulic fluid to transfer energy or generate mechanical force. Hydraulic piston pumps rely on reciprocating motion. Rotational forces are generated along an axis. Fixed and variable displacement pumps are available, as are different types, including axial, inline, bent-axis, plunger, and radial pumps, each with its own unique method of pushing fluid.

On the other hand, gear pumps move fluid via tightly aligned cogs that create suction to draw in and discharge fluid. Pumps with internal or external gears can be used, depending on the application requirements. Lobe, screw, and vane pumps are just some available types. A downside of using gear pumps is that additional devices are needed to control the desired amount of displacement, as they operate on fixed displacement only.

While gear pumps are available in a wide range of displacement sizes and pressures, and they suit various machinery applications, piston pumps offer the benefits of higher pressure ratings and are variable displacement and energy efficient. Rapid cooling means each pump is ready for the next operating cycle and can be serviced soon after shut-off.

Gear pumps typically don’t move more than 50 gallons per minute of fluid. On the other hand, some piston pumps can move hundreds of gallons per minute. Either one has advantages, depending on your hydraulic application.

Hydraulic pumps are available in different types, sizes, pressure ratings, and other specifications. It is important to choose the right pump for your hydraulic system. Gear pumps are suited for various types of machinery. Piston pumps are often found in oil field and agricultural applications, as well as in heavy-duty construction equipment. They are reliable and efficient, and they resist leakage at high speeds and pressures.

High power density, good controllability, and low cost are the most appealing characteristics that make hydraulic systems the best choice for many applications. Current state-of-the-art hydraulic variable displacement pumps show high efficiency at high displacement while they have poor efficiencies at low displacement. This paper proposes a novel alternating flow (AF) variable displacement hydraulic pump to: 1) eliminate metering losses by acting as a high-bandwidth pump for displacement control; 2) achieve high efficiency across a wide range of operating conditions and displacements; and 3) allow multiple units to be easily common-shaft mounted for a compact multi-actuator displacement control system from a single prime mover. A dynamic model using first principles describes the cylinder pressure, flows between pairs of cylinders, and net inlet and outlet flows as a function of the pumps phase-shift angle. The model captures hydraulic check valve dynamics, the effective bulk modulus, leakage flows, and viscous friction. Piston kinematics and dynamics are discussed and energy loss models are presented. A first prototype of the AF pump was constructed from two inline triplex pumps that were modified so that three piston pairs were created. Experiment tests were conducted and used to validate the model. After model validation, simulation results from the model can offer an initial evaluation of this novel pump concept and potential applications and can be used to guide the design for future prototype of the AF hydraulic pump.
