INSTRUCTION MANUAL

THANK YOU FOR CHOOSING SUNFAB

You have chosen SCPD 70/36 DIN, a dual flow pump with differentiated 
flow suitable for combination vehicles with high power take off ratio and high 
output speeds. Compact design and easy installation makes SCPD 70/36 
one of the mainstays for powerful, trouble free hydraulic systems

REMEMBER

A trouble-free hydraulic system is created using selected components and 
correct installation. Consequently, follow the instructions in this manual, 
which includes checking the power take off, tank design, hose dimensions, 
installation and start up. Failure to carry out the manufacturer’s installation 
conditions will invalidate the warranty.

INSTALLATION REQUIREMENTS

POWER TAKE-OFF

• Pump mounting: Spline shaft DIN 5462 / ISO 14.  
  Mounting flange ISO 7653-D.

• The power take off can be engine, flywheel or gearbox mounted

• The output speed of the power take off must not exceed the pump’s max    
  speed, relieved = 2550 rpm

• The permitted torque output on the power take off must be higher than the   
  pump shaft’s torque at maximum pressure

• The power take off’s direction of rotation must correspond with the selected 
  pump, which is supplied in left-hand (L) or righthand (R) designs

NOTE! The cover must not be turned to change the direction of rotation.
