Bearing maintenance
These bearing lubrication sections list different temperatures of the pumped fluid. If the pump is ATEX-
certified and the temperature of the pumped fluid exceeds the permitted temperature values, then consult
your ITT representative.
Bearing lubrication schedule
Type of bearing First lubrication Lubrication intervals
Oil-lubricated bearings Add oil before you install and start
the pump. Change the oil after 200
hours for new bearings.
After the first 200 hours, change
the oil every 2000 operating hours
or every three months.
Grease-lubricated bearings Grease-lubricated bearings are
initially lubricated at the factory.
Regrease bearings every 2000
operating hours or every three
months.
Lubricating-oil requirements
Oil requirements based on temperature
For the majority of operating conditions, bearing temperatures run between 120°F (49°C) and 180°F
(82°C), and you can use an oil of ISO viscosity grade 68 at 100°F (38°C). If temperatures exceed 180°F
(82°C), refer to the table for temperature requirements.
Temperature Oil requirement
Bearing temperatures exceed 180°F (82°C) Use ISO viscosity grade 100 with bearing-frame
cooling or finned-tube oil cooler. The finned-tube
oil cooler is standard with the HT 3196 model and
optional for all other models.
Pumped-fluid temperatures exceed 350°F (177°C) Use synthetic lubrication.
Oil volumes
