Vertical Rigid Pump Coupling

Keyless vertical clamp coupling for vertical pumps using the Anderson Clamp Hub, with adjustable shaft position and rotor lift; about 19,000 lb thrust capacity on a one-inch shaft.

Description

The Vertical Rigid Pump Coupling (Vertical Clamp Coupling) from Coupling Corporation of America uses the patented Anderson Clamp Hub to eliminate keys and "clam shells" in vertical pump drives, while allowing easy adjustment of shaft position and pump rotor lift.

Key features

  • Keyless connection – no vertical key for torque and no split horizontal key to carry rotor weight
  • Very high thrust capacity: about 19,000 pounds on a one-inch shaft
  • Inherent concentricity; halves can be spigoted where balance is critical
  • Reduces maintenance time on vertical pump applications

Installation

  • One half clamps onto the driving shaft, the other onto the vertical pump shaft; a sleeve is bolted to one side
  • The gap between the halves equals the required rotor lift
  • Tightening the connecting bolts lifts the lower half and pump rotor by the correct amount
  • Alignment is adjusted by tightening load screws on the desired side while measuring pump shaft runout
