S Series sand gravel pumps are designed for continuous handling of the most difficult higher abrasive slurry, containing solids too large to be pumped by a standard slurry pump.
1) Total Net Weight— 4450kg;
2) Wet parts— Impeller (diameter: 667mm),Bowl, Back liner;
3) Shaft seal— Packing seal, Expeller seal, Mechanical seal;
1) Impeller — Pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination
2) NPSH — Exceptional NPSHr conditions due to large impeller eyes
3) Large Particles — Large eye openings and vane passages allow for the largest particle flows
4) Expeller (Centrifugal Seal) — Available with low flow water flush or zero flow (grease lubricated) options to provide exceptional sealing where water introduction to the seal is intolerable or limited
5) Stuffing Box — Gland sealing with packing and lantern ring
6) Bearing assembly — A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
8) Frame Base –A very robust one piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.

S series Sand Gravel pumps are designed for the continuous handling of more abrasive slurry which contain solids that are too big to be pumps by other types of pump. They are suitable for delivering slurry in mining, explosive sludge in metal melting, dredging in dredger and course of rivers, and other fields.
