HYDRAULIC INSTALLATION
HYDRAULIC QUICK DISCONNECTS
NPK recommends against the use of non-NPK quick disconnects on hydraulic circuits
operating NPK Products, including Compactor/Drivers for the following reasons:
1. Compactor/Driver operation can cause internal pieces of a non-NPK quick
disconnect (32) to disintegrate. These pieces can migrate into the Compactor/Driver
hydraulic motor, causing damage.
2. If quick disconnects are used when the Compactor/Driver is removed from the
carrier, the disconnects should be capped to keep them clean. If this is not done,
contamination in the disconnect will be flushed into the Compactor/Driver when
reconnected, also causing damage.
3. Quick disconnects create a restriction in the hydraulic circuit. NPK
Compactor/Drivers are back pressure sensitive. Restrictions can cause damage to
the hydraulic motor.
4. The pressure required to operate the Compactor/Driver, plus the restriction of the
quick disconnects may push older, low pressure carriers to the limit of their hydraulic
system, interfering with Compactor/Driver Operation.
5. Quick disconnect restrictions can cause unnecessary heating of the carrier’s
hydraulic system.
NPK encourages the use of a standard hose and fitting connection (39). It is
recommended that when the Compactor/Driver is removed from the carrier, the tube
ends and hose fittings should be capped and plugged to keep them clean.
