High-precision HPK055 left cylinder block designed for stable output and durability in hydraulic piston pumps.
OEM-quality HPK055 left cylinder block for piston pumps
High-strength alloy and precision machining ensure long service life
Provides stable pump displacement and consistent hydraulic output
Wear-resistant bore surface improves pump efficiency and durability
Ideal for pump rebuilders, hydraulic workshops, and distributors
The YNF17046 HPK055 Cylinder Block L is engineered as a high-precision replacement component for the HPK055 hydraulic piston pump. This left-hand cylinder block plays a critical role in maintaining consistent displacement, hydraulic stability, and pump efficiency. Manufactured using high-strength alloy steel and CNC-machined to tight tolerances, it ensures a perfectly smooth bore surface for piston movement, minimizing internal leakage and reducing wear.
The superior structural integrity of this cylinder block allows it to withstand high-pressure operation, continuous vibration, and demanding working environments common in excavators and heavy machinery. Replacing a worn or scoured cylinder block helps restore pump output, improve response speed, and extend the service life of the entire rotating group.
YNF Machinery offers stable supply and competitive pricing, making this part ideal for hydraulic pump rebuilders, machinery maintenance fleets, and global aftermarket distributors.
