Rexroth Gear Pump PGH4-30 040RE11VE4 For Safe Operation And Maintenance Schedule

For safe operation and extended service life of the Rexroth gear pump, a comprehensive maintenance schedule must be implemented for the power unit, machine, or system. This schedule ensures compliance with all intended operating conditions throughout the pump's service period.

Critical operating parameters requiring regular monitoring include:

• Oil cleanliness standards
• Operating temperature range
• Operating medium level

Regular system checks should evaluate these additional parameters:

• Vibration levels
• Noise emissions
• Temperature differential between pump and reservoir fluid
• Foam formation in reservoir
• System leak-proofness

Any parameter deviations may indicate component wear (drive motor, coupling, pump, etc.) and require immediate investigation and correction.

For optimal operational safety, we recommend continuous automated monitoring of these parameters with automatic system shutdown capability when readings exceed normal operating range fluctuations.

Maintenance Recommendations:

• Replace plastic drive coupling components regularly, with mandatory replacement after 5 years
• Follow all manufacturer specifications for component replacement
• Schedule preventive seal replacement by authorized Bosch Rexroth service after maximum 5 years of operation
