Dynaquip Controls 145820.01 Limit Switch Kit

This kit provides a direct replacement limit switch for compatible Dynaquip pump systems. It is designed for maintenance technicians and facility managers who need to restore automatic shut-off function on supported equipment. The component ensures reliable position sensing in fluid handling applications.

Compatibility spans multiple Grainger item numbers

The switch fits Grainger items 26X043 through 26X047, 26X052, 26X059 through 26X062, and numerous 3MR and 3MT series codes. It covers a broad range of Dynaquip pump models used in commercial plumbing. Installers should verify their specific unit against the listed part numbers before ordering.

Replaces worn or failed original limit switches

Upgrading is worthwhile when an existing switch no longer triggers at the correct pressure point or shows physical damage. The kit restores factory safety logic without requiring a full pump replacement. It is not suited for systems using non-Dynaquip control interfaces or custom mounting configurations.

Questions about this item

Will the 145820.01 limit switch kit fit the DynaQuip pump I already have that matches Grainger item 26X043?

Yes, the kit is listed as compatible with Grainger item 26X043, so it will install directly on that DynaQuip pump model.

How can I confirm the 145820.01 kit is operating correctly once installed?

Cycle the pump and verify the limit switch activates at the correct pressure points, stopping and starting the motor as the pressure reaches the set cut-in and cut-out levels.

Does the 145820.01 kit include the mounting hardware or do I need to buy screws separately?

The kit supplies the limit switch assembly designed for the listed DynaQuip models; any additional mounting screws or fittings would need to be sourced separately if not already on the pump.
