This Shurflo high pressure pump model is a direct replacement for the 8000-543-136 but has the capacity to achieve higher pressure.
They have an internal bypass and it has proven to be a real workhorse when it comes to agricultural chemical spraying.
With a 1/2" male inlet and outlet, Santoprene diaphragms and Viton seals, it is suitable for most ag chemical sprays.
It requires a 7.5 amp fuse. We recommend the use of 3/8" 10mm minimum hose with this pump particularly on the discharge side of the pump to eliminate friction loss and pressure loss. With a maximum flow rate (at zero pressure) of 6.8 L/minute and a maximum pressure of 107 PSI, this automatic pressure switch pump is very versatile and reliable.
