HIGH PRESSURE HYDROSTATICS | MULTIPLE UNITS 19

Multiple units.

For open and closed circuit operation.

Design characteristics HPR double pumps Product advantages double, tandem and multiple pumps

— two pumps of the same rated size, fitted back-to-back — only one drive shaft required
— common port plate housing — no splitter box required for the pumps
— single or dual circuit — compact design
— individual control of each single pump
Design characteristics tandem- and multiple pumps — no adverse influence on functionality of the single
rotating groups
— two or more pumps, fitted face-to-back — advantages such as high dynamics and precise control
— open and/or closed circuit remain in full
— tandem pumps: Pumps of the same type
— multiple pumps: Pumps of different types Product advantages double motors

Design characteristics HMV double motors — high conversion range for smooth acceleration
— simplified drive train
— two motors of the same rated size, fitted back-to-back — high tractive effort and high final speed
— common ports for high pressure, servo- and control pressure — fast control response and high starting torque
— can be controlled individually or together
— both motors can swivelled to 0 cc/rev Product advantages tandem motors

Design characteristics tandem motors — double torque with the same gearbox interface by using the
same flange as with the single motor
— two motors of the same type, fitted face-to-back — direct installation in the drive train, gearbox
— separate ports, individual control possible can be omitted
— both motors can swivelled to 0 cc/rev — increased rotating speed and narrower dimensions
than for single motors of the same nominal
size in swash plate or bent axis design
