Boshart Pump Switch - Wide Angle Pump up - Normally Closed

Boshart model FS13U240PB-15 is a wide-angle pump switch in a normally closed configuration for fill tank use, using float switches to detect liquid presence in tanks as the water level changes. It is mechanically operated by switching contacts activated by a ball inside the float housing. Float switches can be mechanical or mercury types, and this model is mechanical. The switch is suitable for liquid tank applications such as septic tanks, sump pits, water tanks, and pump chambers, and is rated for environments up to 140°F. Proper installation also depends on selecting the right cable length and routing for the application. Unlike a pressure switch that is mounted with sealant to a tank tee and wired directly, this float switch uses a piggyback plug for simpler setup. This version is a 240VAC piggyback plug model with AC compatibility and does not require a control box to measure level through a separate control box.

The Boshart Pump Switch - Wide Angle Pump up - Normally Closed is a reliable solution for controlling pumps in various liquid tank applications. Designed for environments with temperatures up to 140°F, this pump switch is versatile and efficient.

Benefits for Liquid Level Monitoring

• Provides automatic pump control based on liquid level and helps determine whether liquid is present or absent before the pump responds

• Simple installation with piggyback plug connection

• Reliable mechanical operation with minimal moving components; mercury float switches contain liquid mercury to open and close contacts

• Suitable for a wide range of liquid handling applications, where proper flow conditions also support sewage pump performance and help prevent overflow

• Selecting the right float switch for the application can make a difference in reliability and help prevent overflow; for instance, a switch can fail if its environment or rating is unsuitable

• Eliminates the need for a separate control box

• Helps maintain desired liquid levels in tanks and chambers; if needed, it is easier to replace a faulty switch with the correct type

• By contrast, pressure switches may be fine-tuned with adjustment nuts and adjustable differential springs, turning the nut clockwise raises cut-in and cut-out thresholds, and some models include a low-pressure cut-off

Additional Information

The Boshart FS13U240PB-15 Wide Angle Pump Switch is designed for dependable liquid level control in demanding applications, with level sensors like float switches helping operate connected equipment by sending a signal when the liquid reaches a certain level. Its normally closed configuration, mechanical switching design, and piggyback plug connection provide a straightforward and reliable solution, with the correct switch type depending on the application and operating conditions, and the exact open or closed response depending on the switch position and application, such as pump-up, high-level alarm, or fill tank use. A normally open open float switch is a common use where a rise must turn equipment on, while closed float switches suit other control functions.
