What We Do
Our Services
Parker Engineering provides a comprehensive range of Industrial Rebuilding, Machining, and Surface Treatment Services. From a single worn Shaft to a complete Pump Overhaul, we have the Equipment, Expertise, and Processes to restore your Components to full Service — often better than new.
Rebuilding & Repairing
Restore worn Components to OEM Specs — or better.
Parker Engineering specializes in the complete Rebuilding and Repair of Industrial Components. Whether a Part has suffered Wear, Corrosion, Impact Damage, or Fatigue, our Team restores it to full operational condition. We work to original Equipment Manufacturer Specifications or improve upon them using modern Materials and Techniques.
- Full Disassembly, Inspection, and Dimensional Analysis
- Worn Surfaces rebuilt using Welding, Plating, or Thermal Spray
- Re-machined to original Tolerances
- Suitable for Pumps, Compressors, Gearboxes, and more
Machining & Fabricating
Precision Cuts. Tight Tolerances. Every Time.
Our Machine Shop is equipped for both Manual and CNC Machining, handling everything from one-off custom Parts to Production Runs. We fabricate Components from raw Stock or modify existing Parts to meet new Specifications. Complex Geometries, unusual Materials, and demanding Tolerances are our specialty.
- CNC Turning, Milling, and Boring
- Manual Lathe and Mill Work for custom one-offs
- Fabrication from Steel, Stainless, Aluminum, Bronze, and more
- Reverse Engineering and custom Part Creation
O.D. & I.D. Grinding
Cylindrical Precision — inside and out.
Outer Diameter and Inner Diameter Grinding delivers the tight Tolerances and fine Surface Finishes required for rotating and sliding Components. We grind Shafts, Sleeves, Bores, and Journals to exacting Specifications, ensuring proper Fit and long Service Life in demanding Applications.
- O.D. Grinding for Shafts, Rolls, and Cylinders
- I.D. Grinding for Bores, Sleeves, and Housings
- Surface Finishes to Ra 8–16 Microinch or better
- Tolerances held to ±0.0001"
Welding
Structural Strength. Precision Joins.
Our certified Welders handle a wide range of Welding Processes for both Structural Repair and Precision Buildup Work. From heavy Structural Fabrication to delicate TIG Work on thin-wall Components, we select the right Process and Filler Material for each Application.
- MIG, TIG, and Stick Welding
- Stainless Steel, Carbon Steel, Aluminum, and Exotic Alloys
- Buildup Welding to restore worn Dimensions
- Structural Repair and Fabrication
Hard Chrome Plating
Unmatched Hardness. Superior Wear Resistance.
Hard Chrome Plating deposits a dense, extremely hard Chromium Layer onto Metal Surfaces, dramatically extending Service Life in high-wear and corrosive Environments. It is the Industry Standard for Hydraulic Rods, Pump Shafts, and any Component requiring a combination of Hardness, low Friction, and Corrosion Resistance.
- Hardness up to 70 Rc
- Excellent Corrosion and Wear Resistance
- Applied to Shafts, Rods, Cylinders, and Plungers
- Ground and Polished to final Dimensions after Plating
Hard Facing
Protect high-wear Surfaces with tough Overlay Alloys.
Hard Facing applies Wear-Resistant Alloy Overlays to Surfaces subject to Abrasion, Erosion, or Impact. It is an economical way to extend the Life of new Components or restore worn ones, using Materials selected to match the specific Wear Mechanism in your Application.
- Carbide, Chrome Carbide, and Cobalt-Based Overlays
- Applied by Welding or Thermal Spray
- Ideal for Mixer Blades, Impellers, Wear Plates, and Valve Seats
- Dramatically reduces Replacement Frequency
HVOF Coating
High-Velocity Performance for extreme Environments.
High Velocity Oxy-Fuel (HVOF) Thermal Spray produces dense, tightly bonded Coatings with very low Porosity and high Hardness. It is the preferred alternative to Hard Chrome in many Applications, offering superior Wear and Corrosion Resistance while meeting modern Environmental Standards.
- Tungsten Carbide, Chrome Carbide, and Cermet Coatings
- Coating Density >99% — minimal Porosity
- Hardness up to 72 Rc
- Environmentally preferred alternative to Hard Chrome
Nickel Plating
Chemical Resistance. Dimensional Restoration.
Electroless and Electrolytic Nickel Plating provides excellent Corrosion Resistance, uniform Deposit Thickness, and good Hardness. Electroless Nickel is especially valued for its ability to coat complex Geometries uniformly, making it ideal for internal Bores and intricate Parts.
- Electroless Nickel for uniform Coverage on complex Shapes
- Electrolytic Nickel for heavy Buildup and Dimensional Restoration
- Excellent Resistance to Chemicals, Acids, and Alkalis
- Can be Heat-Treated to increase Hardness up to 70 Rc
Plasma Spraying
Ceramic and Metallic Coatings for extreme Conditions.
Plasma Spraying uses a high-temperature Plasma Arc to melt and propel Coating Materials onto a Substrate, enabling the application of Ceramics, Cermets, and Specialty Metals that cannot be deposited by other means. It is used for Thermal Barriers, Electrical Insulation, and extreme Wear Applications.
- Alumina, Zirconia, and other Ceramic Coatings
- Metallic and Cermet Coatings for Wear and Corrosion
- Thermal Barrier Coatings for high-temperature Components
- Electrical Insulation Coatings
Control Valve Trims
Rebuilt to Spec. Fabricated New. Ready for Service.
Parker Engineering offers complete Rebuilding and new Fabrication of Control Valve Trims for industrial applications. Whether your existing Trim is worn, eroded, or damaged — or you need a new Trim fabricated to specification — our Machine Shop has the precision equipment and experience to deliver components that meet or exceed OEM standards. We work with all major valve types including CCI, Fisher, Masoneilan, Flowserve, and more.
- Rebuilding of worn or damaged Control Valve Trim Sets
- New Trim Fabrication to OEM or custom Specifications
- Compatible with CCI, Fisher, Masoneilan, Flowserve, and other major Brands
- Plug, Seat, Cage, and Stem Components — all rebuilt or fabricated in-house
- Hard Chrome Plating and HVOF Coating available for extended Trim Life
- Fissure Valve and Anti-Cavitation Trim Rebuilding
