Pumps
Pumps are among the most common components Parker Engineering rebuilds and repairs. Whether centrifugal, positive displacement, gear, or vane type, we restore pump shafts, impellers, casings, and wear rings to original specifications — or better. Hard chrome plating and HVOF coatings dramatically extend shaft and sleeve life in abrasive or corrosive service.
Common Parts & Components
- Pump shafts — chrome plated or HVOF coated
- Impellers — rebuilt, balanced, and re-machined
- Wear rings and sleeves — replaced or re-machined
- Casing bores — re-machined to accept oversized components
- Stuffing box areas — rebuilt and ground to spec
- Pump housings — welded, machined, and restored
Gears & Gearboxes
Gearboxes and gear components require precise dimensional restoration to maintain proper mesh, backlash, and load distribution. Parker Engineering machines gear shafts, bores, and housings back to specification, and applies hard chrome or nickel plating to restore worn journal surfaces. We also fabricate custom shafts and bushings when replacement parts are unavailable.
Common Parts & Components
- Gear shafts — chrome plated and ground to bearing fit
