Schneider Electric (Square D) 9013GSG2J20 Pump Pressure Switch 20/40 PSI Adjustable Differential

The Schneider Electric Square D 9013GSG2J20 20/40 Pump Switch Adjdiff is a pressure switch used for pump usage in HVAC systems. It works by keeping an eye on the pressure differential between two system points and turning on the pump when the pressure drops below a predetermined level. The pump's operation can be precisely controlled by the adjustable differential, ensuring that it only operates when required. Sump pumps, condensate pumps, and centrifugal pumps all frequently use this switch. The HVAC systems can reap numerous advantages from the 9013GSG2J20 as it regulates the pump's operation automatically. It aids in maintaining the ideal system pressure, guarding against over- or under-pressurization damage to equipment.
