Frequently Asked Questions
What is the function of a relief valve in a hydraulic pump system?
The relief valve limits the maximum system pressure, preventing overload damage to the pump and other hydraulic components.
How to identify a genuine hydraulic pump?
Genuine pumps have a logo, clear OEM part number marking, and a serial number that can be verified via the official system.
What is the appliion of gear pump part number 560-0886?
560-0886 is a pilot gear pump suitable for all series of mini and small excavators.
Why does a hydraulic pump produce excessive heat?
Excessive heat is caused by system pressure exceeding ratings, internal pump friction (wear), low oil level, or using oil with incorrect viscosity.
Can a hydraulic pump be adjusted for higher flow rate?
Consult technical documentation for specific pump models. Improper adjustments may void warranty and cause system damage.
