All three models have the same displacement (12 mL/r) and rotation direction. The primary differences are in port configurations: G0PE1 (first two models) vs G1PE2 (third model). Port differences affect connection types and system integration options. Select based on your system's connection requirements and layout.
12 mL/r models are ideal for low-flow applications where precise metering is critical. They require smaller motors, have lower power consumption, and are more compact. Use for applications with flow rates below 20 L/min at typical speeds, or where space constraints exist.
For 12 mL/r models at 250 bar, approximately 5-7 kW motor is typical. Actual power depends on operating pressure and flow rate. Calculate based on your specific parameters (pressure × flow rate ÷ 600 × efficiency) and add a 10-20% safety margin.
Regular maintenance includes checking oil level and quality, inspecting for leaks, monitoring pump noise and temperature. Check and replace filters regularly (every 500-1000 hours). Inspect coupling alignment periodically. For first 100 hours of operation, check for any unusual signs and consider oil change after initial run-in period.
Yes, within the specified speed range (735-1800 rpm). However, avoid operating below minimum speed as it may cause insufficient lubrication. Do not exceed maximum speed to prevent cavitation and mechanical stress. For variable speed applications, ensure the drive system can maintain proper speed control.
