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.
