Controls used on Hartmann PVX, PVD and PVC pumps incorporate a modular design concept. This allows the combination of multiple controls by stacking them and also permits the same controls that operate an 8cc pump to operate a 190cc pump. Users of these Hartmann series pumps have the ability to change controls in the field by ordering some of our 30 plus different factory set or adjustable controls.
