RADIAL PISTON PUMPS RKP-II FOR LOW-FLAMMABILITY FLUIDS MULTIPLE PUMPS
RKP MULTIPLE PUMPS Additional pumps can be tandem-mounted on the radial piston pump, so that all pump stages can be driven by the same shaft. Radial piston pumps (the same size or smaller than the first pump stage) can be mounted directly. Other pumps may be added on using adapter flanges for SAEA, SAE-B or SAE-C respectively. For the maximum permitted through-drive torque for driving add-on pumps, please refer to the table below.
Adding on RKP, SAE-A, SAE-B or SAE-C adapters Permissible through-drive torques

400 Nm (295. 0 lbf ft) 620 Nm (457. 3 lbf ft)
The through-drive torque required to drive add-on pumps is determined by reference to the following variables: V [cm3/rev] p [bar] hm [%] M [Nm] Displacement Pressure Hydro-mechanical efficiency Through-drive torque
Through-drive torque from pump stage 1 to 2:
M1 = 1. 59 ·

Example Referred to a pump combination RKP63 + RKP 63 + RKP32 + AZP 16 280 bar, 210 bar, 150 bar, 50 bar this means: Design of 1st through-drive The pressure and flow of the 1st pump stage are irrelevant to the torque transferred by the through-drive. This torque can be calculated using the above formula: Design of 2nd through-drive
M2 = 1. 59 ·

(
M2 = 1. 59 · (32 · 150 / 93 + 16 · 50 / 90) Nm M2 = 96 Nm (70. 8 lbf ft) Likewise, the value 96 Nm (70. 8 lbf ft) lies below the relevant threshold value of 400 Nm (295. 0 lbf ft) for the through-drive from an RKPII 63 to an RKPII 32. Design of 3rd through-drive Similarly, a value of 14 Nm (10. 3 lbf ft) is obtained for the torque required to drive the add-on gear pump. Thus, the through-drives for this pump combination are permissible with the stated pressures. 14
M1 = 1. 59 · (63 · 210 / 95 + 32 · 150 / 93 + 16 · 50 / 90) Nm M1 = 318 Nm (234. 5 lbf ft) The value 318 Nm (234. 5 lbf ft) is below the threshold value of 400 Nm (295. 0 lbf ft) specified in the above table for mounting an RKP 63 on another RKP 63.
