A bitumen pump that sits inside the tank
The SB series flanges directly onto a fixed or mobile tank, with the pump body immersed in the product. The pump stays at the temperature of the bitumen around it, so the gears are surrounded by hot binder and are ready to turn. The pump is self-priming and positive displacement, which gives a flow rate tied to speed and a spreading rate you can control from the drive.
Two built-in valves, four operations
Two valves are built into the pump and can be manual or motorised. By setting them you load the tank, recirculate inside it, discharge, or transfer product without passing through the tank. On a spreader this takes the place of external valves and pipe runs, each of which would need heating and each of which could block.
An integrated heating circuit warms the pump before start-up.
Gear maintenance without emptying the tank
The gears can be removed without draining the tank. For a contractor in the middle of the surfacing season this means the load of hot bitumen stays where it is while the pump is serviced.
Five models, SB 200 to SB 1000, cover theoretical flow rates from 57 to 1093 l/min, so the same design suits compact spreaders and large road tankers.
Spreaders, tankers and storage tanks: what to send us
Machine builders usually send us the tank drawing, the binder and the flow rate required. Our technical office in Bologna confirms the model, the valve actuation and the drive speed. Beyond hot bitumen, we normally propose the SB series for bitumen emulsions and tar on road machinery. For pipework away from the tank there is the jacketed CR series.
