AX is the innovative piston pump series, designed and industrialized to match newest requirements of electric machines with variable speed drives. The AX piston pump is available in different sizes with displacement ranges form 18 to 122 cc and with single, two or four quadrant operation. Various combinations with tandem pumps are possible as well.
