MTM Hydro BP9 Unloader - 4500 PSI

Description MTM Hydro's BP unloader series was specifically manufactured for total stop electric pressure washing installations that are typically found in car wash bays. These unloaders have the unique ability to restart pressure at one third of the working pressure while normal trapped pressure unloaders will restart within 100 PSI which causes pumps to cycle constantly. By restarting at a much lower PSI the pump accrues fewer hours and will last longer. This specific unloader does not have the Easy Start Valve located at the bottom of the of the BP92 unloader, however with its superior performance in fixed installations, the BP9 unloader is highly recommended for wash bays and car washes.   Bypass - Two available 3/8" NPT Female ports Inlet - One 3/8" NPT Female Outlet - 3/8" NPT Female Mounting port - 3/8" NPT Female bottom mounting port available Other - 1/4" Side port located near handle for supporting accessory     Max - 8 GPM Max - 195°F temp rating
