Shurflo Demand Diaphragm Pump 24V Max 3.6 GPM 45 PSI Coated Motor - 2088-573-534

Genuine Shurflo (Pentair) 2088-573-534 automatic demand diaphragm pump with a sealed motor, designed for industrial spraying and liquid transfer. This is an original Shurflo pump, not a copy or house brand.

The 3-chamber pump delivers 3.6 GPM open flow at 24 VDC nominal. Its pressure switch automatically starts the pump as pressure drops and shuts it off at the factory-set 45 PSI. A built-in check valve prevents reverse flow, and the permanent magnet motor includes thermal protection.
