Q: My Kubota U17 excavator is making a whining noise near the pump. Is the PVD-OB-18P filter involved?
A: Yes. A clogged PVD-OB-18P suction filter causes pump cavitation. This noise is the sound of air bubbles imploding, which can destroy the piston shoes of your Nachi pump. Replacing the filter is the first step in diagnostics.
Q: How often should I change the filter on my PVD-0B-18P pump?
A: For mini excavators in heavy dust environments, we recommend inspection every 250 hours and a full replacement every 500 hours to prevent contamination of the engine rebuild components and hydraulic valves.
Q: Why Choose This Filter Element?
A: Because it features an OEM-standard tri-metal structure in its reinforcement and is Trusted by repair shops & equipment fleets worldwide for maintaining system pressure.
