A piston pump is a positive displacement pump that uses one or more pistons to move fluid through a system. It works by the reciprocating motion of a piston within a cylinder. As the piston moves, the volume within the cylinder changes, drawing in and out fluid. Typically weighing around 40-45kg, its relatively modest weight facilitates installation and layout in a variety of equipment and systems. 16-36 mm²/s, in this viscosity range, the hydraulic oil can form a good lubrication and sealing effect in the pump, to ensure the efficient operation of the pump, reduce internal leakage and wear. Minimum 10 mm²/s, maximum 1000 mm²/s, but in extreme viscosity conditions, attention should be paid to the possible adverse effects on the start-up, operation and life of the pump. It has a certain maximum pressure rating. This indicates the highest hydraulic pressure that the pump can withstand and generate. High - pressure capabilities make it suitable for applications that require significant force, such as in heavy - duty hydraulic machinery. For example, in a construction - grade hydraulic excavator, this pump can provide the necessary pressure to power the boom and bucket cylinders.
