Multiple pump units

Advantages

• Double, Tandem, and Multiple Pumps
• Only one drive shaft required
• No splitter box needed for the pumps
• Compact design
• Individual control of each single pump
• No adverse impact on the functionality of individual rotating groups
• Benefits such as high dynamics and precise control remain fully preserved

HMV Double Motors

• Wide range of gear ratios ensuring smooth acceleration
• Simplified drive system
• High tractive force and maximum speed
• Fast control response and high starting torque

Tandem Motors

• Double torque with the same gearbox interface, thanks to using the same flange as in a single motor
• Direct installation in the drive system, eliminating the need for a gearbox
• Increased rotational speed and smaller dimensions compared to single motors of the same nominal size in swashplate or axial designs
• Design Characteristics

HPR Double Pumps

• Two pumps of the same nominal size, mounted back-to-back
• Common port plate housing
• Single or dual circuit

Tandem and Multiple Pumps

• Two or more pumps mounted face-to-back
• Open and/or closed circuit
• Tandem pumps: Pumps of the same type
• Multiple pumps: Pumps of different types

HMV Double Motors

• Two motors of the same nominal size
• Common ports for high pressure, servo pressure, and control pressure
• Can be controlled individually or together
• Both motors can be swiveled to 0 cc/rev

Tandem Motors

• Two motors of the same type, mounted face-to-back
• Separate ports, allowing individual control
• Both motors can be swiveled to 0 cc/rev
