Pumps of the DL series can be used as vacuum pumps or as compressors of filtered air on stationary of mobile equipment for creating vacuum, for pneumatic transportation or for the suction inside a tank of liquid or solid waste.

This vacuum pump is designed with a new intake manifold. A non-return valve is placed in the suction part of the manifold. The main goal is to reduce the higher temperature reached from all the parts. An equal distribution of the aspirated air is guaranteed by a four-entry points. The air injected does not reduce the volumetric efficiency.
