    ### Jabsco Dual-Max 7.5 Freshwater Pressure System 24V

The 24V Dual-Max 7.5 combines two automatic pumps for a vessel with changing freshwater demand.

### About this product

One pump runs for lower demand; the second starts when additional flow is needed. An integrated bladder accumulator limits pressure variation, improving delivery at the taps and temperature control in the shower.
