FAQ


Q: What are the primary failure signs for a hydraulic main pump?
A: Common diagnostics include slow hydraulic response, excessive whining noises under load, and high oil temperatures. If your excavator loses digging force or experiences jerky boom movements, the PVK-2B-505-YYB internal cylinders or port plates may require replacement to restore system pressure.
 
Q: What are the critical installation technical requirements?
A: Before mounting, the hydraulic tank must be cleaned and the filters replaced. It is mandatory to fill the pump case with clean hydraulic oil through the highest drain port before startup to prevent dry-running and catastrophic internal damage during the first few seconds of operation.
 
Q: How do I ensure procurement compatibility for my fleet?
A: To confirm the PVK-2B-505-YYB fits your machine, verify the number of mounting splines, the flange bolt pattern, and the inlet/outlet port locations. Providing your machine's nameplate photo helps our team cross-reference the exact specifications for a guaranteed fit.
 
Q: How does the pump handle extreme environment performance?
A: This assembly is designed for heavy-duty construction machinery operating in harsh climates. Its high-grade seals maintain integrity at temperatures up to 95 degrees Celsius, while the cast iron housing resists thermal expansion and contraction in sub-zero mining environments.
 
Q:  What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
