A large roading firm wanted a pump for unloading bitumen from their trailer at a flowrate of 600l/min. The pump needed to be hydraulic driven as electrical power was not feasible. The bitumen temperature was between 160 – 180°C.
Pump & Valve sold a Roper 3732HBFRV pump complete with a hydraulic motor mounted on a baseplate. This pumpset connected into the hydraulics on the truck giving complete independence. Roper 3600 series gear pumps are rated to 232°C so the bitumen temperature was well within specification.
