What We Gain by Switching to Keepwin Spare Parts
Deep Cost Savings
We trim our maintenance budget by up to 70 %—Keepwin’s parts come in at just 30–50 % of the OEM price without hidden mark-ups or long‐haul freight charges.
OEM-Level Quality & Service Life
Every rod, valve, or diaphragm meets the same API 618 tolerances and metallurgy specs as the originals, so we run the equipment just as long—and often longer—without unplanned shutdowns.
Rapid Turnaround
With local machining hubs and stocked raw material, Keepwin can ship within a week, slashing our downtime compared with the OEM’s multi-month lead times.
Precision Build, Backed by Experts
Parts are cut on 5-axis CNCs, verified on CMMs, and signed off by a veteran engineering team. That gives us confidence the replacement will drop straight in and perform from the first start-up.
Problem: The OEM had discontinued valve assemblies for a pre-2012 SIAD hydrogen compressor. Downtime was costing > US $6,000 per day.
Action: The customer shipped a worn valve to Keepwin’s reverse-engineering center. We performed 3-D laser scanning, material spectroscopy, and finite-element validation, then machined a drop-in replacement on our 5-axis CNC line.
Result:
3–5 extra years of machine life without a frame change-out
≈ US $100,000 saved versus a full OEM upgrade kit
Lead time: 8 days door-to-door—70 % faster than the legacy supplier
Problem: Western sanctions blocked the end user from importing OEM piston rods, putting a 10 MW natural-gas compressor at risk.
Action: Keepwin dispatched field-measurement engineers to the site. Using portable CMMs, they captured full geometry and hardness data in 24 hours, emailed CAD files to our Tianjin plant, and launched immediate production.
Result:
Perfect OEM fit verified by ultrasonic run-out and dimensional tests
Zero production delay—rod installed within two weeks of the outage
30–50 % lower cost than the original part, despite emergency logistics
Whether your challenge is an obsolete original model or sanction-restricted supply chain, Keepwin’s certified compressor spare parts restore uptime quickly and economically—no OEM dependency required.
