Z Series: Dredge and Gravel Slurry Pumps

Dimensionally interchangeable with Warman ® G ® Series pumps

 

Schurco Slurry ® Z Series pumps are designed to handle very large particles for gravel and dredging operations. Schurco Slurry ® Gravel pumps are designed for the continuous handling of the most difficult higher abrasive slurries, containing solids too large to be pumped by a standard slurry pump.

 

 

Z Series Features
 

• These pumps are constructed of a single casing connected by means of clamps and a widened suction port

• WETTED PARTS

     ○ IMPELLERS – 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

     ○ NPSH - exceptional NPSHr conditions due to large impeller eyes

     ○ LARGE PARTICLES - large eye openings and vane passages allow for the largest particle flows of any Schurco Slurry® pump

• SEALS– Schurco offers a wide variety of seal options to suit any process requirements

     ○ 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

     ○ STUFFING BOX – gland sealing with packing and lantern ring

     ○ SCHURCO LOW-FLOW SEAL – Schurco® offers a variety of low-flow seals, which can significantly reduce water usage in the stuffing box – the low-flow seal systems can be applied in a variety of applications using several material and component options

• BEARING ASSEMBLY – all bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination – oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field

• BASE – a single piece base with integrated adjustment mechanism for impeller clearance within pump – bearing assembly locks into base using four heavy-duty bolts – three custom designed mounting modes available: overhead using integrated single pedestal system, side-by-side with adjustable motor mount, and direct-coupled with precision in-house alignment (optional VFD packages available)

Typical Z Series Applications
 

Heavy Mining – Explosive Sludge In Metal Smelting – River And Pond Dredging – Heavy Refuse Removal – Larger Particle Or Low NPSHA Applications
