Deming Horizontal Two-Stage Split-Case Pump Features

  • Casing - Horizontally  Split, on Center Line Permits Easy Removal of Entire Rotor Assembly when Upper Half of Casing is Removed.
  • Mechanical Shaft  Seals- can be Installed at Factory or in Field without Special Machining of Casing, because Box is Identical for Both Applications.
  • Outboard (thrust) Bearing - is Locked to Shaft using a Heavy Duty, Spring Steel, Retaining Ring. Any Unaccountable Axial Thrust is Carried by the Bearing. Grease Lubrication, with Flush-Filling Connections, is Standard Construction. Water-Jacketed are Optional.
  • Reduced Stuffing Box Pressure - Through the use of a Balancing Pipe Connecting Pressure-Reducing Bushings in both Stuffing Boxes, the Pressure in the Second-Stage Box is Effectively Reduced by One-Half.
  • Bronze Shaft Sleeves - Are Standard Equipment. Stainless Steel is Available.
  • Gasket Joint - Between Shaft Sleeve and Impeller Prevents Leakage under Shaft Sleeve and Reduces Shaft Corrosion.
  • Bearings - are Single-Row, Deep-Groove Type Ball Bearing, Mounted in Dirt and Moisture-Proof Cast-Iron Housings, Bolted to Lower Half of Casing. Identical Bearings on Both Ends are Interchangeable to Reduce Maintenance Difficulties.
  • Flange-Type Floating Wearing Rings - with Labyrinth-Type Seal Between Flange and Casing.
  • Two-Piece Gland - with Drip Chamber to Confine Leakage, Held in Place with Bronze Studs and Nuts, Permits Packing to be Replaced without Disassembly of Pump.
