The hydraulic pump, the heart of the hydraulic system, is a source of mechanical energy that converts mechanical power into hydraulic energy.
While mechanical power is the product of torque and speed, hydraulic power is the pressure during flow. When the hydraulic pump operates, it creates negative pressure at the pump inlet, which pushes liquid from the tank into the feed line to the pump.

How does a hydraulic pump work?
The functional principle of the hydraulic pump is the same as all other pumps. The pump creates negative pressure at the inlet through mechanical action.
This causes the liquid to enter the pump inlet due to atmospheric pressure. The pump then pushes the fluid into the hydraulic system. The pump contains two check valves.
If the piston is pulled to the left, negative pressure is created in the pump chamber. This negative pressure holds the check valve in place and allows atmospheric pressure to force the fluid in the cylinder through the check valve.
The volume of fluid displaced by the piston during the delivery stroke is called the displacement volume of the pump.
The need for hydraulic maintenance is determined from time to time by the operating conditions of the various hydraulic components. For example, a service interval of 10,000 hours (approximately 14 months) is generally recommended for piston pumps.
