HYDRAULIC INSTALLATION
HYDRAULIC QUICK DISCONNECTS
NPK prefers the use of a straight JIC connection
(39)
when installing its Material
Processor onto a carrier.
NOTE:
Care should be given when removing the Material Processor to make sure that
the hoses are plugged and the tube ends are capped to prevent contamination from
entering the hydraulic system.
NPK recommends against the use of non-NPK hydraulic quick disconnects on fluid
circuits operating NPK Products, including Material Processors, for the following
reasons:
1. The hydraulic pulsations caused by the Material Processor can cause internal pieces
of the non-NPK quick disconnect
(32)
to disintegrate. These pieces can migrate into
the Material Processor, causing damage to the unit. That damage is not covered by
NPK’s warranty.
2. Contamination can enter the hydraulic system if the quick disconnect ends are not
kept clean. The quick disconnects should be capped to keep them clean. If this is
not done, contamination in the quick disconnect will be flushed into the hydraulic
system, causing internal damage to the Material Processor.
3. Most quick disconnects create a restriction in the hydraulic circuit. NPK Material
Processors are not pressure sensitive, but the restrictions cause unnecessary
heating of the oil. Also, the pressure required to operate the Material Processor,
plus the restriction of the quick disconnects may push an older, lower pressure
carrier to the limit of its hydraulic system. This would interfere with the proper
operation of the Material Processor. However, the NPK approved quick disconnects
are properly sized so that the Material Processor operation is not affected.
