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.

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.
