Driving several hydraulic pumps from one engine or electric motor requires consideration of each circuit's demand. A splitter gearbox must suit the combined load, individual pump speeds and physical installation.

jbj Techniques' pump-drive guide explains six considerations:

» Power: establish each circuit's flow and pressure requirements, including which functions operate simultaneously.

» Prime mover: confirm available power, speed and mounting interfaces.

» Hydraulic pumps: identify pump models, rotation, shaft connections and required driving speeds.

» Service factor: account for operating conditions, duty and required service life.

» Dimensions: check pump spacing, mounting clearances and access for pipework.

» Cooling: assess thermal capacity and whether additional oil cooling is required.

These checks help define a practical drive arrangement for equipment such as drilling rigs, crushers, screeners and marine machinery.

jbj Techniques can assist from initial calculations through to gearbox selection, mechanical integration and associated cooling requirements.
