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.)
