These are different buying decisions. For a pump, identify the drive and operating requirements; for a replacement cylinder or connector, identify the exact dimensions and interfaces. A pressure figure alone is not enough.
PTO pump: check both shaft speeds
The 20 cc displacement is volume per pump revolution. Read the model-specific guide for direct drive versus the listed gearbox assembly; do not treat an unverified seller flow figure as a measured result.
Compare the part number, stroke, mounting dimensions and connections with the machine documentation. The component catalog provides a starting point; confirm the exact variant with the seller.
Record the thread standard, size, sealing arrangement and working conditions. Similar-looking connectors are not proof of a match; use the part-identification checklist to organize the missing details.
Check the exact manual and seller documentation for the selected model. This is buying guidance, not an installation procedure or permission to work on a pressurised system.
