5502-TOICO-V77D Diaphragm Pump

115V AC Regulated Pressure Pump 

The 5502-TOICO-V77D is a pressure-regulated 115V AC diaphragm pump designed for smooth, consistent water delivery without the need for additional control components. Built on the Aquajet 550 platform, this model features an integrated pressure-sensing controller that maintains steady output at approximately 50 PSI, making it ideal for systems that require consistent pressure and simplified installation.

With a 5-chamber diaphragm design, this pump delivers low pulsation flow while remaining self-priming and capable of running dry, ensuring durability and reliability in demanding TOICO applications.
