Pumps and drives: keep process role separate from machine state

Choose recognizable pump geometry, then layer driver, availability, command, feedback, and fault information deliberately.

Recognize the process function

Centrifugal, positive-displacement, vacuum, and specialty pumps can require different silhouettes on documentation. The approved P&ID legend remains the authority.

On an HMI, the driver and pump may be shown as one operating object or as coordinated objects. Whichever model is chosen, keep the state mapping consistent across the project.

Review the operating object

  1. 01

    Identity

    Show the equipment tag and service where the display hierarchy requires it.

  2. 02

    State

    Distinguish stopped, transitional, running, unavailable, and faulted conditions.

  3. 03

    Control context

    Expose mode, command source, permissives, and interlocks in the detail view.

  4. 04

    Process evidence

    Use pressure, flow, current, or speed trends when they help confirm performance.
