Buy HPV55(PC120) Hydraulic Pump Parts | Partsdic®

Pump Type: The HPV55 (PC120) hydraulic pump is a variable displacement axial piston pump.

This means that it can vary the flow rate of hydraulic fluid to meet the specific requirements of the machine's operation.

Flow Rate: The flow rate of this pump can vary depending on the machine's needs but typically ranges from 30 to 45 liters per minute (LPM). It's important to note that the flow rate can be adjusted to optimize efficiency and performance.

Pressure Rating: The HPV55 (PC120) hydraulic pump is designed to operate at high pressures, often exceeding 3000 PSI (pounds per square inch). This high-pressure capability is crucial for the hydraulic system to perform heavy-duty tasks.

Variable Displacement: This hydraulic pump's variable displacement feature allows it to adjust the volume of hydraulic fluid it delivers based on the load and demand. This ensures that the system operates efficiently and prevents excessive wear and tear.

Piston Assembly: The core of the hydraulic pump consists of a piston assembly. It typically includes a set of axial pistons that move within a cylindrical block. These pistons are precisely machined to maintain a tight seal and minimize leakage.

Swashplate Mechanism: The swashplate is a crucial part of the hydraulic pump that controls the piston stroke.

It can tilt to increase or decrease the piston's stroke length, thus adjusting the pump's displacement and flow rate.

Drive Shaft: The hydraulic pump is driven by a mechanical input, typically from the engine or an electric motor, through a drive shaft. The rotational force from the drive shaft is converted into reciprocating motion by the piston assembly.

Control Mechanism: To regulate the flow rate and pressure, the HPV55 (PC120) hydraulic pump may have a control mechanism. This can include features like pressure relief valves and flow control valves to maintain system stability and protect against overpressure.

Materials: The components of the hydraulic pump are often made from high-strength materials such as hardened steel or cast iron to withstand the high pressures and loads encountered during operation.

Seals and Bearings: To prevent hydraulic fluid leakage and ensure smooth operation, the pump employs various seals and bearings at critical points within the assembly.

Mounting and Interface: The hydraulic pump is designed to be mounted securely within the hydraulic system, typically through flanges or bolted connections. It also interfaces with other hydraulic components such as hoses, fittings, and reservoirs.
