Implementation Methodology & Engineering Steps

Controlled engineering process from initial calculation and modeling to machining, dynamic pressure testing, and commissioning.

ENGINEERING & DESIGN

Teardown & Inspection

Disassembly, degreasing, and micrometer evaluation of pistons, cylinder block, valve plate, swashplate, and bearings.

FABRICATION & MACHINING

Precision Rebuilding

Approved replacement parts or precision lapping are performed alongside new shaft seals and control adjustments.

TESTING & VERIFICATION

Test Bench Testing

Flow rate vs pressure curves, volumetric efficiency, case drain leakage, and control response are verified on our test stand.

Technical Data & Standards

Uluslararası endüstriyel standartlar (ISO 4413 / DIN), malzeme toleransları ve saha doğrulama gereksinimleri.

TECHNICAL VERIFICATION & DATA SPECIFICATIONS
ISO COMPLIANT
Fault Symptoms
Noise, overheating, pressure loss, flow reduction, excessive drain leakage
Root Causes
Fluid contamination, cavitation, dry running, incorrect oil viscosity, mechanical wear
Diagnostic Output
Restoration, part renewal, flow test report, or replacement recommendation

Frequently Asked Questions

Cavitation, air ingress on suction line, blocked suction filter, low oil level, high viscosity, or worn swashplate bearings.

Depending on component wear and replacement part availability, standard overhauls take 2 to 5 business days.

Yes. Contaminated fluid, aerated oil, high temperature, or blocked return lines will rapidly destroy a newly rebuilt pump.
