We provide rotary positive displacement pumps to load or unload fluid products ranging from diesel fuel, jet fuels, unleaded gasoline to lubricants, greases and asphalts. Our pumps can be truck-mounted with our unique hydraulic mount. Low speed-high torque motors have been an excellant match for the GRANCO pump power requirements and provide great flexability in locating the pump and its controls. The new flange mount provides direct drive mounting of the hydraulic motor, permitting an even more compact and rugged arrangement, and eliminates a separate motor mount and the need to align the drive. On most truck applications, the PTO and the universal joint is eliminated and replaced by hydraulic lines from an engine driven hydraulic pump. The GRANCO transfer pump can be located anywhere and the controls placed where convenient. More than one pump can easily be installed with proper valving. The extra advantages of hydraulic drives can be used which are infinite speed adjustments, reversibility for two way pumping and pressure relief protection on the hydraulic side. The advantages are a compact rugged package, the ability to conveniently locate the pump, simple installation with no alignment required, and the infinite speed selections. The added features are the use of multiple pumps, variable speed, reversible flow, hydraulic relief protection, and flexible control location.
