U Series: Unlined High Chrome Horizontal Slurry Pumps

U Series Features
 

• WETTED PARTS

     ○ IMPELLERS – uses the same high chrome impellers as the lined pump series for even greater interchangeability plantwide – 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 2 to 6 vanes on certain sizes) offer wider hydraulic options in single sizes

     ○ 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

• 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)
