U Series Unlined Slurry Pump

Unlined Pump U Series

The U Series has the same hydraulic performance profiles of their lined counterparts in the S and L Series, and can be applied on existing lined slurry pump installations using a conversion kit.

  • Heads through 240ft (73m)
  • Flow-rates through 6,000gpm (1,350m3/h)
  • Casing pressure tolerance 300psig (2,020kPa)

Selected Applications

  • sugar beets
  • coarse sand
  • coarse tailings
  • dredging
  • phosphate matrix
  • minerals concentrate
  • bottom/fly ash
  • lime grinding
  • oil sands
  • mineral sands
  • fine tailings
  • coal

U Series Features

Wetted Parts

  • Impellers – uses the same high chrome impellers as the lined pump series for even greater interchangeability – pump out vanes on rear and front (on closed impellers) reduce recirculation within pump – optional castings of straight or semi-Francis vanes (from 2 to 6 vanes on certain sizes) offer wider hydraulic options in single sizes
  • Bowl/Casing – the unlined casing is extra thick high-chrome alloy material hardened to over 650 Brinnell. The suction side is cast in a contoured shape to mate with the impeller eyes to increase efficiency and reduce recirculation in the casing.

Seals

  • Expeller (Centrifugal Seal) – no external sealing water required where applicable
  • Stuffing Box – flushed gland sealing with braided packing and a lantern ring
  • Mechanical Seals

Bearing Assembly

  • Cartridge-style bearing housing allows for removal from pump and assembly in controlled environment
  • Oversized shaft diameters and reduced overhang in the wet-end contribute to long life and reliability in the field

Interchangeable with Warman® AHU® and MU® Series pumps.
