Description

The AP and APx pump series are designed for heavy duty continuous service at high temperatures and high pressures in oil refinery , petrochemical and chemical industries and represent the evolution our best engineering evolution.

The AP is an overhung, horizontal, centerline mounted, single stage, radially split process pump, in two basic version with standar closed impellers and with special design for low capacities, designed fully comply with ISO 13709 (API 610) standards where affidability and safety are important.

The AP process pump includes the latest in mechanical seals technology and is used in heavy-duty refinery services, petrochemical plants, gas processing and offshore services.

The modular construction system, with identical dimension parts , allows minimum spare inventories, since only four sizes of bearing frames foreseen to cover the complete range of pumps sizes.

The improoved bearing frame with robust shaft make a quite operation and long reability pumps and shall be fitted with a air cooling device and options such as magnetic oil seals and monitoring instrumentation.

The mechanical seals and auxiliaries supplied are in full compliance with the requirements of ISO 21049 (API 682).

The fluids pumped include sour water, gasoline, light hydrocarbons,and vacuum bottoms.

The customers benefit from the robust construction,the versatility in application, and the long reliable service life.









The APx is designed to provide an optimum solution for lower flows and higher heads.

Some applications require a horizontal direct drive pump capable of delivering 3 m3/h (13 USgpm) capacity and head to 360 m (1,200 ft). Customers require low NPSHr, while meeting ISO 13709 (API 610) vibration levels.

The APx utilizes a precision cast,semi-open, multi-vaned impeller that produces much more head per mm of impeller diameter than does a conventional enclosed impeller. The impeller design provides geometric flexibility to adjust the best efficiency flow while providing excellent efficiency and a stable performance curve.

All the standard ISO 13709 (API 610) material combinations are available from S-1 to D-2 for hot or cold services.
