STORAGE:
If the pump and coupling are to be stored, drain the pump

and pour non-detergent SAE 30-weight oil into the pump port.

Apply grease to the pump or the coupling shaft extension, if

present or accessible.

Viking suggests rotating the pump shaft every 30 days to

circulate the oil in the pump. The coupling should be stored

in a dry area.

Note: If the liquid to be pumped reacts with oil, use an

acceptable alternate.

LUBRICATION:

Some bearing carriers require external lubrication. This must

be applied slowly with a handgun to lubrication fittings every

500 hours of operation with multi-purpose grease, NLGI # 2.

Do not over-grease. Applications involving very high or low

temperatures will require other types of lubrication. Refer to

ESB-515. Consult factory with specific lubrication questions.
