SUMPTROL E47523 Float Switch

SUMPTROL Sumptrol E47523 Float Switch is an automatic float-operated device that controls pumps in tanks or sumps by responding to liquid level with a buoyant float attached to a lever. It is part of the 840 Bulletin Float Switch family, designed to start a pump when the liquid is low and stop it at a preset high level, with configurable Tank Operation or Sump Operation and conversion between modes across Styles A, B, and C variants; Style D is tank-only and Style DS is sump-only. The switch features contacts rated for motor and pilot-duty circuits, enabling direct control of standard pump motors in industrial environments. Mounting options include floor-mounted operator assemblies for flexible installation, such as a Style A float-switch assembly with a lever-based actuation method. Temperature guidelines from historical Rockwell documentation indicate operating temperatures as low as –22°F (–30°C) and storage temperatures up to 200°F (93°C), with particular operating ranges varying by mechanism to suit industrial settings. The E47523 Sumptrol float switch thus provides reliable, level-based automation for pumping applications, leveraging proven 840-series construction and configurable operation modes to fit diverse tank and sump configurations.
