Mechanical / Hydraulic

• Pump Type: Single Stage Double Suction Horizontal Split Case Pump
• Impeller Design: Balanced double-entry impeller with Francis vanes, keyed to shaft, dynamically and hydraulically balanced. Designed for low NPSH requirements and maximum efficiency. Impeller hubs can accommodate wear rings.
• Casing Design: Heavy-duty construction with integral pump feet. The top half of the casing is easily removed for service without disturbing piping. Inlet and outlet flanges are cast in the bottom half casing. Flanges and casing are tapped and plugged for gauge and priming connections. An air release valve and flushing connections are provided in the upper casing.
• Flanges: 125 ANSI or 250 ANSI Flanges Standard.
• Wear Rings: Case wear rings are separate from the case and replaceable. Impeller wear rings are optional.
• Sealing Options:
  • Standard Mechanical Seal
  • Optional Balanced Seal
  • Optional Packing
  • Seal Flushing: Recirculation Line (Standard), Filter & Abrasive Separators (Optional)
• Bearings: Heavy-duty type, grease lubricated. Double suction design virtually eliminates axial thrust, reducing bearing loading and increasing life.
• Modular Construction: Utilizes three basic bearing and shaft modules, allowing for multiple seal and construction options, simplified maintenance, and design flexibility.
• Additional Options:
  • Drip Type Base
  • Two Rotation Options
  • Packed Stuffing Box
  • Balanced Mechanical Seals

Dimensions

Dimensions vary significantly by model number and motor frame. See the official PDF for exact tabulated values.

• English dimensions are in inches, metric dimensions are in millimeters (in parentheses).
• Motor dimensions are approximate and vary by manufacturer and motor type.
