Guidelines for Handling and Maintenance of PZS Series Piston Pump
Hydraulic Fluid Management:
- It is crucial to use high-quality hydraulic fluid with a viscosity range suitable for operational conditions, typically between 20 to 200 mm²/s. Proper fluid management ensures optimal performance and longevity of the PZS Series Piston Pumps.
- Regular checks and maintenance of fluid levels, as well as filtering to prevent contamination, are essential. The system should maintain a cleanliness level of NAS 10 or better.
Startup and Air Bleeding Procedures:
- Before starting the pump, ensure it is fully primed with hydraulic fluid to avoid dry running. This process is critical after long periods of inactivity or initial installation.
- Air bleeding must be conducted carefully, particularly in specific installation orientations to prevent air entrainment, which can cause operational issues.
Installation and Piping Considerations:
- When installing the pump, flexible couplings should be used to connect the drive shaft, avoiding radial or thrust loads on the pump shaft. Proper alignment and secure fittings are vital for system integrity.
- The suction and return lines must be configured to ensure smooth fluid flow and prevent cavitation.
