Bearing Lubrication – Oil
Oil lubrication on HSCS Series pumps is considered special. Oil

lubrication pumps are installed with Trico oilers (See Figure 11).

The oilers keep the oil level in the housings constant.

After the pump has been installed, flush the housing to remove

dirt, grit, and other impurities that may have entered the bearing

housing during shipment or installation. Then refill the housing

with proper lubricant. (The housing must be filled using the Trico

oiler.) The oil level will be maintained by the Trico oiler. (See the

SERVICE section for proper instructions.)
