INDEX Section Modification from former edition. ID02

Modular design and versatility are the main features of “MAGNUM” series gear pumps and motors. Mounting flange, body and rear cover can be easily assembled to obtain multiple pumps of same or different groups available in standard version, common inlet or separated stages. Wide selection of drive shafts and mounting flanges in SAE version with the possibility of integrated outboard bearing to suit all the applications with axial and radial load on the drive shaft. Port locations available in side or rear locations, and combination of side and rear locations. The low level of noise emission with...

MAGNUM series pumps can be coupled together in combination. Where input power requirement of each element varies, that 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 separated inlet, common inlet and separated stages. Combination...

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 1 shows that the torque absorbed by hDp35»80 is 2523 lbf in (285 Nm) and the graph 2 shows that the torque absorbed by HDP30»27 is 620 lbf in (70 Nm) acceptable value because it doesn’t exceed the maximum connecting shaft torque that is 1505 lbf in (170 Nm), see page 27 The torque...
