RITO 312710 HPV118 Hydraulic Pump Head Cover ZX200-3 ZX210-3 ZX240-3 Excavator Main Pump Housing Case Cap Spare Parts

Micro-cracks in your main pump case can cause sudden pressure drops and oil atomization, leading to catastrophic fire hazards. When head covers warp under extreme pressure, expensive piston assemblies inside are destroyed. Do not let a weak pump casing disable your ZX200-3, ZX210-3, or ZX240-3 earthmovers.

FAQ


Q: Fault Diagnosis: What are the key signs that a pump head casing cover has suffered structural damage or fatigue?
A: Fine oil mist spraying from housing joints, an inability for the pump to maintain max pressure settings, and high-pitched whining noises due to air entering the system indicate a failed casing cap.
 
Q: Installation: How should service techs prepare the mating surfaces before bolting down the new pump head cover?
A: All old gasket material must be scraped completely clean. Use a precision straight-edge to verify the pump barrel face is flat, then install a brand-new high-pressure seal kit before torquing.
 
Q: Procurement Verification: Which exact hydraulic pumps can utilize this specific replacement housing case cap?
A: This cover is configured exclusively for HPV118 model piston pumps found inside Hitachi ZX200-3, ZX210-3, and ZX240-3 medium-sized excavator lines.
 
Q: Extreme Environment Performance: How does this casing cap handle heavy pressure spikes when mining hard rock?
A: The high-tensile alloy material features exceptional yield strength, allowing the head cover to endure high-frequency hydraulic pressure spikes without expanding or causing internal part misalignment.
 

Q:  What quality options are available?

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