The Wangen X-unit is a module added before the pump, serving as a preliminary stage where the fluid is freed from harmful solids that may damage the pump. The X-Unit consists of the X-CUT and X-TRACT components sold separately. The X-tract serves as a screening chamber where large solids are collected. Meanwhile, the X-CUT cuts down the smaller solids that are able to pass beyond the X-TRACT. Together, they minimize risks of blockage on the pipelines to the pump or the inlet port of the main pump.
