What used to be considered okay as a lifetime for an electric submersible drainage pump is now held to higher standards. On top of that, sustainability considerations require submersible pumps to be economically viable to repair to a larger extent than ever before. This fundamentally changes the way submersible pump manufacturers must think. Repairability needs to be factored into the design from the first sketches of a new pump design however, this sometimes conflicts with manufacturability. One of the absolute best ways to avoid repairs is to extend the service intervals.
