NACHI series Hydraulic pump Accessories , piston Fixed pumps Parts

Hydraulic pumps are critical components of hydraulic systems, converting mechanical energy into hydraulic energy. They generate flow with enough power to overcome the pressure induced by the load. Here's a breakdown of the typical parts you would find in a hydraulic pump:

Casing (Housing): The external shell that encases the pump internals, designed to withstand internal pressures.

Rotating Group: In many pump designs, this includes parts that rotate to create the pumping action. It can include gears, vanes, pistons, and a rotor.

Gears (Gear Pump): Some hydraulic pumps use interlocking gears to pump fluid. Typically, there is a pair of gears - a drive gear and a driven gear.

Vanes (Vane Pump): These are blade-like components that extend radially in a rotor slot and slide in and out as the rotor turns, maintaining contact with the housing to form pumping chambers.

Pistons (Piston Pump): In axial and radial piston pumps, these components pressurize the fluid by moving back and forth in their respective cylinders as the drive shaft rotates.

Cylinder Block: In piston pumps, the cylinders in which the pistons move are contained within this block.
