Boshart 1/4"fpt Pressure Switch 20-40

Standard Duty Pressure Switch for Well Pumps

Boshart's PS2040 pressure switch is engineered for reliable control of submersible, jet, and reciprocating well pump systems. This standard-duty diaphragm switch automatically starts your pump when system pressure drops to 20 PSI and stops it at 40 PSI, maintaining consistent water pressure in your tank.

Key Features

• Automatic Operation: Pressure-actuated contacts eliminate manual pump control
• Adjustable Settings: Fine-tune cut-in and cut-out pressures to match your system
• 1/4" FPT Connection: Standard fitting for easy installation into pressure tanks
• Electrical Ratings: Rated for 115/230V operation, suitable for most residential well systems
• Durable Construction: Steel body withstands harsh well environments (Temperature range: -22°F to 257°F)

When to Use

Use the 20-40 PSI model for shallow wells, low-flow systems, or applications requiring lower cut-in pressure. Boshart pressure switches are industry-standard in water well installations and retrofit projects.
