9.3.1.3 If the reservoir or tank is not equipped with low-level

switch, visually check the lubricant level and refill before all

lubricant is used. If the reservoir or tank is allowed to run dry,

air will be introduced into the system, requiring that the

system be bled.

9.4 MATERIAL CONSIDERATIONS

9.4.1 Material Cleanliness. System life and consistent

operation will both be improved by using only clean lubricant.

On all pumps, the lube piston diameter is very close to the

diameter of the chamber in the pump body. Contaminants in

the lubricant could cause scoring in this area, resulting in

erratic pump operation and costly parts replacement. Make

sure that lubricant used to fill the system is clean. If there is

doubt about cleanliness, lubricant should be filtered before

being introduced into the system. After filtering the system,

make sure the lubricant supply is protected from debris. For

protection of divider valves and the equipment being lubri-

cated, an in-line filter (oil) or strainer (grease) should be

installed between this pump and the first stage (master)

divider.

Lubriquip recommends a minimum oil cleanliness level of

ISO 18/14 per ISO standard 4406 for all oil systems.

Lubriquip further recommends that all grease systems be

equipped with a 100 mesh strainer. Refer to bulletin 15200

for available lubricant filters and strainers.

9.4.2 Temperature Effects. Flow characteristics of the

lubricant may change if the area the Modu-Flo system is

used in goes through drastic temperature changes. Choose

a lubricant that will flow properly at all temperatures expected

in the system environment.
