S Series: Heavy-Duty Slurry Pumps

Dimensionally interchangeable with Warman ® AH ® Series pumps

 

For the past half-century end-suction, split-case, centrifugal slurry pumps have set the world standard for heavy duty abrasive pumping applications. 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 engineering services that are often costly or not available elsewhere.

 

Application customization comes standard with this line using a variety of metallurgic 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 metallurgic and elastomeric options (metal and elastomer interchangeable) – active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue

     ○ THROATBUSH – wide variety of metallurgic and elastomeric options (metal and elastomer interchangeable) – adjustable via cotters to account for wear over time and increase efficiency

     ○ CHEMICAL COMPATIBILITY – operating pH range from 3 to 14 – especially corrosive chemicals handled using diverse variety of elastomeric wetted parts

• 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

• CASING – split-case design allows for ease of access and maintenance on wet end parts – cast ductile iron with exterior ribbing provides increased pressure ratings and reliable service over time

• 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)
