SJE HiTempMaster™ High Temperature Float Switch for Sump Pumps (Up to 200°F)

Reliable Pump Control for High Temperature Sump Applications

When standard float switches fail under heat, the SJE HiTempMaster™ high temperature float switch is built to keep your system running reliably. Designed specifically for hot water and high-temperature sump environments, this mechanically activated pump switch provides consistent, automatic control in applications where temperatures can reach up to 200°F (93°C).

From industrial wastewater and boiler discharge to high-temperature sump pits, the HiTempMaster™ provides reliable pump-down control, eliminating the risks of traditional float switches.

What This Float Switch Does

The SJE HiTempMaster™ pump switch automatically turns your pump on and off based on liquid level. As the float rises and falls, it activates a mechanical switch to control pump operation, helping prevent overflow, protect equipment, and maintain system efficiency.

Unlike standard float switches, this model is engineered for high-heat environments, making it ideal for applications where elevated temperatures would otherwise cause premature failure.

Why Choose a High Temperature Float Switch?

In high-temperature sump systems:

• Standard float switches can warp, degrade, or fail
• Electrical components may become unreliable
• Pump control becomes inconsistent or unsafe

The HiTempMaster™ is designed to overcome these challenges with:

• Heat-resistant materials
• A protective float housing
• Stable operation even in harsh conditions

This ensures accurate pump cycling and longer service life in demanding environments.
