Answer: Our in-house gear grinding (JIS B 1702-1 Class 0) and automated axial clearance adjustment (±0.005mm tolerance) eliminate internal leakage. Each pump is tested on a hydraulic dynamometer for 2 hours at 280 Bar to validate efficiency.
Answer: Yes. Provide flange dimensions (ISO 6162/SAE J518) and flow requirements. We modify porting, shaft splines (DIN 5480/SAE J498B), and displacement within 7 days, with 3D drawings pre-approved.
Answer: Order pre-filled pumps (charged with HITACHI recommended oil) and use our alignment jig (FATP-091) for 15-minute installation. Old units can be returned for core credits.
Answer: Add our centrifugal pre-filter (removes 95% of 40μm+ abrasives) and upgrade to tungsten carbide-coated gears (15,000-hour lifespan vs. standard 8,000 hours).
