S Series Heavy-Duty Slurry Pump

End-suction, split-case, centrifugal slurry pumps have set the world standard for heavy-duty abrasive pumping applications for decades. With large shaft diameters, heavy-duty bearing assemblies, and robust slurry pumping capacity, Schurco Slurry ® pumps provide a cost-effective and ideal alternative to longer lead times and the difficulty associated with working with large multinational companies.

Application customization comes standard with this line by applying a wide variety of metallic and elastomeric parts options, an assortment of seal arrangements, and a standard impeller adjustment mechanism incorporated into every base assembly.

S Series Features

Wetted Parts

Impellers– wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) – pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination – optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on certain sizes) offer wider hydraulic options in single sizes

Liners – wide variety of metallic and elastomeric options (metal and elastomer liners are interchangeable) to select from in order to provide the longest wear life possible.


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® AH® series pumps.
