Vg = 4 – 27.9 ccm/rev
Pres nom = up to 250 bar
Pres max = up to 280 bar
Are double pumps group 2 It have intermediate sealing. Each stage keeps the characteristics of the simple pump.
Can be combined steps with the same displacements or steps with different displacements. By extension can be coupled pumps of different group sizes. In this case, the steps are placed in decreasing displacements (Example: HP 21). 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.
