Lubrication Of The propeller vertical axial flow turbine pumps

Oil Lubrication

All line shaft bearings are oil lubricated from oiler on the motor base. Oiler can be hand operated or solenoid for automatic lubrication.

The bottom pump bearing is packed with water resistant grease, securing a long period of operation.

Grease Lubrication

Bronze line shaft bearings are lubricated by a grease pump, on the motor base.

Water Lubrication

The line shaft bearings are made of rubber and are water lubricated. The suction bowl bearing is grease lubricated. This type is recommended for clear water to ZLBoid oil contamination. The pump should not be dry, as the rubber bearings will seize.

For turbid water we can also use enclosed line shaft and lubrication with clean water from an external source
