For bitumen spreaders and tanks

SB series pumps for bitumen spreaders

The SB series is designed for bitumen spreaders. The pump flanges directly onto a fixed or mobile tank with its body immersed in the product. Valves and heating circuit are built in.

Mounted on the tank, immersed in the bitumen

The body of the pump sits inside the tank, surrounded by hot bitumen. It stays at the temperature of the product and is ready to start. The pump is self-priming. This layout suits bitumen spreaders and tankers as well as fixed storage for bitumen.

Two built-in valves, four operations

Two valves are incorporated in the pump, with manual or motorised control. With them you load the tank, recirculate inside it, unload it and transfer product from one external point to another without passing through the tank. You do all this with one pump and no external valve manifold.

Heating circuit and maintenance

An integrated heating circuit warms the pump before start-up, which matters after a night stop when bitumen emulsions or tar have cooled.

The gears can be removed without emptying the tank. You service the pump on the vehicle and get back on the road sooner.

Five sizes for road machinery

Five models cover displacements from 127 to 754 cm³/rev and flow rates from 57 to 1093 l/min. Tell our technical office in Bologna, Italy, the capacity of the tank and the spreading width, and we will indicate the size and the drive.

Frequently asked questions

Can the SB pump be serviced with the tank full?

Yes. The gears can be removed without emptying the tank.

Are the valves manual or motorised?

Both versions are available. The two valves are incorporated in the pump.

What is the difference between the SB and CR series?

The SB mounts on the tank with the body immersed and has built-in valves. The CR series is a jacketed pump installed in the pipework of a plant.
