Hydraulic Pumps: Definition, Types, Uses and Products
Hydraulic pumps and, motors, and valves are the basic mechanisms of a functioning hydraulic system. Hydraulic pumps are one of the most integral parts of a hydraulic system. The primary function of a hydraulic pump is to transfer hydraulic fluid, like oil, from one point to another within a hydraulic system to create hydraulic power. In this system, mechanical energy is created through power transmission.
We will be looking at the different parts of hydraulic pumps and the different types of hydraulic pumps like gear pumps, variable displacement pumps, and radial piston pumps (hydraulic piston pump). If you want more information about the structure and representation of hydraulic pumps, you can also check out the ‘hydraulic pump symbol’ on the internet.
The Different Parts of Hydraulic Pumps:
Hydraulic Pumps Reservoirs: Hydraulic pump reservoirs store the hydraulic fluid and let its solid impurities settle down. It also helps transfer the heat in the system and releases moisture in the hydraulic fluid.
Hydraulic Pumps: The primary function of hydraulic pumps is to convert mechanical energy to hydraulic energy.
Hydraulic Pump Valves: Hydraulic pumps valves control the flow of the hydraulic fluid in a hydraulic system.
Hydraulic Pump Actuators: They function at the end of the system and convert the hydraulic energy back to mechanical energy.
Types of Hydraulic Pumps: gear pump hydraulic, variable displacement pump, and radial piston pumps.
- Gear Pump Hydraulic: A gear pump hydraulic machine uses hydraulic power to move materials in a hydraulic system.
- Variable Displacement Pump: A variable displacement pump converts mechanical energy into hydraulic or fluid energy.
- Radial Piston Pumps (hydraulic piston pump): Radial piston pumps (hydraulic piston pump) function under very high pressure, sometimes as high as 700 bar.

Options- Port options, Shaft options, High-pressure ports
Advantages- Low noise, Low pulsation, Long service life, High power density
Hydraulic Pumps – Group 00
General description- The gear pumps are designed to transform the mechanical energy as the energy of the working liquid (pressure and flow rate). They are simplified in construction, and they have a relatively low cost. All these benefits ensure their wide application in hydraulic systems.
Drive arrangements- The pump drive may be direct or indirect (by gear, chains, or belt transmissions). Both drives should not impose axial or radial forces on the pump shaft.
– Working liquid: hydraulic oils with viscosity 16 … 200 mm2 /s;
– Degree of filtration: 15 … 25 ìm;
– Ambient temperature range: – 22 … 55 °C;
– Fluid temperature range: – 25 … 80 °C;
– Inlet pressure, absolute: 0.8 … 2.2 bar;
– Outlet pressure up to 250 bar
