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.

Lubricate the bearings with oil
Use a high-quality turbine oil with rust and oxidation inhibitors.
1. Remove the fill plug.
2. Fill the bearing frame with oil through the filler connection, which is located on top of the bearing
frame.
Fill the bearing frame with oil until the oil level reaches the middle of the sight glass (319).

Lubricate the bearings with pure oil mist
Oil mist is an optional feature for this pump.
• To lubricate bearings with pure oil mist, follow the instructions provided by the manufacturer of the
oil-mist generator.
The inlet connections are on the top of the bearing frame.
