Description

Manufacturing Process

  1. Material Selection – High-strength cast iron or aluminum is used for durability and heat resistance.
  2. Casting/Forging – The pump housing is cast or forged to achieve the required strength and shape.
  3. Machining – CNC machining ensures precise internal dimensions for efficient fluid flow.
  4. Gear/Piston/Vane Assembly – Depending on the pump type, gears, pistons, or vanes are installed for hydraulic operation.
  5. Seal & Bearing Installation – High-quality seals and bearings are fitted to prevent leaks and reduce friction.
  6. Surface Coating – Anti-corrosion treatments such as anodizing, powder coating, or electroplating are applied.
  7. Quality Testing – The pump is tested for pressure capacity, leakage, and operational efficiency.
