Are double bidirectional pumps with a common external drainage. Because of common external drainage, these pumps have not intermediate sealing between steps. Each step keeps simple pump characteristics. It can be combined steps with the same or different displacement. It can realize multiple pumps by 2, 3 or 4 steps, but must be limited the torque on the drive shaft on the value indicated and the value for the second stage torque at 65 Nm.
