The selection problem
Your demand changes.
Your selection should account for it.
A machine that fits the design point may struggle at low demand. TheOptimal compares combinations across the duty points that matter to your operation.
Understand operation
Review flow, pressure, speed and power at each duty point, with operating limits alongside the result.
Make a considered choice
Compare energy estimates, costs and spare capacity. Keep the assumptions with your selection.
From duty to decision
See the selection process.
Follow a simple pump example from a changing duty profile to a machine combination and its engineering review.
