Making Shaft Lift Adjustments in Vertical Turbine Pumps

The first step in setting the lift adjustment is to determine the available space. Measure the line shaft height with the VTP in the vertical position and the impellers resting on the bottom of the bowls. Then, lift the pump rotor until the impellers rub the top of the bowls and note the change in the line shaft height.

All You Need to Know About: Vertical Shaft Impactor (VSI) …

The product is generally of a consistent cubical shape, making it excellent for modern Superpave highway asphalt applications. The rotor speed (feet per minute) controls final particle size. The VSI's high cubical fracture percentage maximizes first-pass product yield and produces tighter particle size distribution.
