Industries & Components


Pump component manufacturing requires expertise in design, molding, knowledge of hydraulic requirements, as well as accurate finish machining.

AMPO can manufacture from as-cast to fully finished machined components for this industry; from screw, diaphragm or vertical pumps to single/multi-chamber split-body pump components By combining different casting processes (Replicast ceramic molding, or sand-casting using 3D cores), AMPO achieves the demanding surface and hydraulic finishes required by this industry. In addition, we can also offer such other services as:

  • Manufacturing component welding
  • Pressure testing
  • Painting
