Benefits

Bearing assembly 

• A large diameter shaft with reduced impeller overhang results in minimal deflection in the seal area and decreased load at the bearings.
  Heavy-duty roller bearings extend mean time between rebuilds.
  Only six through bolts and two clamping plates are needed to rigidly secure the cartridge housing to the one-piece base.

Cover / frame plates

• High strength ductile iron cover and frame plates support the abrasion resistance liner components.
• Industry leading 4000 KPa (580 psi) working pressure.
• Extensive reinforcing ribs minimize liner deflection and improve wear and performance characteristics.
• Double wall construction permits full wear utilization of the replaceable liners.
• Direct bolted discharge piping minimizes risk of flange failures common on hard iron unlined pumps.

Suction Cover 

• separate fully removable suction cover facilitates access and replacement of impeller throatbush, and shaft sleeve without disturbing cover plate or discharge piping.

Liners

• Field replaceable liners are bolted to the cover and frame plates for positive attachment and ease of maintenance.
• Available in a variety of erosion and corrosion resistant metals and elastomers to maximize individual part life and extend preventative maintenance cycles.
• Hydraulic design of the volute liner has an optimized geometry to provide long wear life across a wide range of flows.

Impeller

• Specifically designed hydraulics emphasize solid passing capability, head generation, wear life, and efficiency to delvier overall outstanding performance
• Aggressive expelling vanes on the front shroud minimize recirculation and improve throatbush wear life.
• Optional expelling vanes on the back shroud reduce stuffing box pressure and axial loads to improve bearing life.
  

One-piece base

• Massive one piece base supports the cartridge bearing assembly and effectively transmits forces to the foundation.
• Base includes an external adjustment mechanism to maintain impeller to throatbush clearance for optimal pump performance.
