Gear & Screw Pumps
Engineered for petroleum, petrochemical, lubrication, and heavy industrial applications with pulse‑free flow, high reliability, and low total cost of ownership.
Engineering Overview
Gear Pumps
Precision external gear pumps for continuous duty. Between‑bearings design, double helical gears, high pressure capability. Ideal for lubrication, fuel transfer, and hydraulic systems.
Twin Screw Pumps
Hydraulically balanced twin‑screw technology for low pulsation, quiet operation. Handles viscous fluids, multiphase, and high‑temperature applications. Self‑priming, continuous flow.
Positive Displacement – volumetric efficiency independent of pressure. Ideal for viscous fluids.
API 676 – Petropedam designs and manufactures in full compliance with API 676, ensuring safety, reliability, and interchangeability.
