INDEX Section Modification from former edition.

From the KAPPA series, we now introduce the KAPPA “Compact” line. The main feature of this new line is a solid, compact 2-piece construction. The new Kappa “Compact” line allows you to include many functions in a reduced envelope (space). The new KAPPA “Compact” line is a direct result of feedback received from Casappa customers. This feedback has given Casappa the opportunity to understand the needs of our customers and implement the hydraulic knowledge gained into new and improved products. The “Compact” line provides exceptional quality and reliability thanks to tri-dimensional modeling,...

KAPPA series pumps can be coupled together in combination. In applications where the input power requirement of each section varies, the section with the greater requirement must be at the drive shaft end, and progressively smaller to the rear. Features and performances are the same as the corresponding single pumps, but pressures must be limited by the transmissible torque of the drive and connecting shafts. To have appropriate data, use the formula below. The maximum rotational speed is that of the lowest rated speed of the single units incorporated. Available with common inlet. For more...

p [bar] - [(psi)] p [bar] - [(psi)] KP 20 - PLP 20 (3) DRIVE SHAFT SELECTION Let us consider a double pump KP30»34 + PL20»20. if we suppose that we have to work with the first pump at a pressure of 2900 psi (200 bar) and the second pump at a pressure of 2175 psi (150 bar), the graph (2) shows that the torque absorbed by Kp30»34 is 1106 Ibf in (125 Nm) and the graph (3) shows that the torque absorbed by PLP20»20 is 505 lbf in (57 Nm) acceptable value because it doesn’t exceed the maximum drive shaft torque that is 974 lbf in (110 Nm), see page 32. The torque to be transmitted by the first...
