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.

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
