• Pressure lubrication is required with hydrodynamic thrust bearings.
Bearings
Bearing type Characteristics
Inboard (radial)
• Consists of a single-row deep-groove ball bearing (standard)
• Carries only radial load
• Optional sleeve bearings
Outboard (thrust)
• Consists of a pair of single-row angular contact ball bearings

radial and thrust loads
• Optional hydrodynamic thrust bearing for use with sleeve type journal
bearings
Shaft
The heavy duty shaft has these characteristics:
• Designed for cartridge mechanical seals
• Minimal shaft deflection at the seal faces (0.002 in. [0.051 mm]) when run in the worst-
case condition (typically minimum flow)
• Critical speed at least 20% above design operating speed
Direction of rotation
The shaft rotates clockwise or counterclockwise when viewed from the power end.
Nameplate information
Important information for ordering
Every pump has a nameplate that provides information about the pump. The nameplate is
located on the pump casing.
When you order spare parts, identify this pump information:
• Model
• Size
• Serial number
• Item numbers of the required parts
Refer to the nameplate on the pump casing for most of the information. See Parts List for item
numbers.
