The company says the new pumps are made to be changed easily and cleanly and to offer added water-separation efficiency with high dust-retention capacity. Two variants are available, with single- or two-stage separation: The single-stage variant is engineered to filter dirt particles and water in one step, while the two-stage variant filters in two separate steps: first the dirt, and then the water, via a water-repellent synthetic fabric.
The filters are designed to removing more than 93 percent of contaminants when new, MAHLE says.
