Information:

Design Features:

  • Easy maintenance due to back pull-out design
  • Extensive interchangeability of parts
  • Manufactured and inspected to rigid standards
  • Quiet operation
  • Self venting center-line discharge
  • Confined casing gasket
  • Drilled and tapped gauge connections are standard on suction and discharge ports
  • Mount with motor feet, or motor and pump feet for convenience

The Casing is a radially-split casing with center-line discharge that can be left in the line while servicing the pump, eliminating needless disconnecting of pipes. Tapped openings are provided for draining and gauge connections. Double volute design where radial loads demand. Center-line discharge allows self venting preventing possible pump failures due to vapor lock. The Impeller is a balanced impeller designed with balancing chamber and pressure relief holes in the impeller that reduce axial thrusts to a minimum, ensuring smooth performance and long life.
