RUSKA 7350 Pump Lubrication
W Caution
The threaded portion of the RUSKA 7350 pump spindle requires
periodic lubrication. Failure to lubricate the pump spindle can
cause premature failure of the pump spindle and nut resulting
in permanent pump damage.
Approved Lubrications
Jet Lube AP-5 Grease (part number 45-342)
Jet Lube MP-50 Moly-paste
Frequency of Lubrication
The frequency of lubrication is dependant upon the frequency of instrument use. On a
highly utilized system, the pump must be lubricated every other week. Also the pump
should be lubricated any time that the pump shows signs of loss of lubrication along the
face of the pump threads.
If a pump position error occurs, along with checking the condition of the pump and pump
over-travel limit switches, please check the pump lubrication. An inadequately lubricated
pump can sometimes be the cause of pump-position error detection by the system
software.
Lubrication Procedure
The threaded portion of the pump plunger requires periodic lubrication. The pump may
be lubricated by either injecting the lubricant through the grease fitting located on the left
side of the instrument or by applying the grease directly to the threads of the pump
plunger. Either way, the power to the system should be removed when applying the
lubrication to the pump.
When applying grease directly to the pump, extend the pump plunger such that the
majority of the threads are exposed. Using the lubrication provided with the system, or
one of the lubrications noted in the approved lubrication list, disperse a generous amount
of lubrication all along the threaded portion of the pump plunger.
W Caution
Only the lubrication defined on the approved lubrication list
above can be used. Substituting this lubrication can cause
permanent damage to the pumping mechanism.
Fuse
The main fuse is a 6 AMP, 250V type 3AB-Slow blow (part number 3926870).
Cleaning
When necessary, clean externally using a damp lint-free cloth and mild liquid detergent.
