GravelMAX  slurrypump

Casing: Designed for minimum slurry turbulence and even wear. Includes integral wear ring, carrier, and adjustment screws for on-line adjustment and elimination of suction side recirculation.

Wear Ring: Adjustable wear ring assembly to permit closing of suction side impeller clearance during operation. This reduces slurry recirculation and lowers pressure at the suction area, thereby maintaining flow and reducing wear.

Impeller: Designed for high slurry efficiency and hydraulic performance. Machined surface at the eye for wear ring adjustment and high expelling vanes.

Backliner (dependent on pump size): Designed for close clearance at the back. Matching full impeller diameter and profile for close operating clearance.

Wear Parts: Designed hydraulically to wear evenly. Constructed of high chrome at 680/720 Brinell hardness.

Power Frame: Heavy duty cast iron pedestal with external bearing assembly adjustment mechanism. Drilled for overhead motor mounting assembly.

Bearing Assembly: Heavy duty shaft and indirect fitted taper roller bearings rated at 100,000 hrs B-10 life minimum. Bearing arrangement designed to prevent over greasing and ingress of slurry

Design Advantages:

High Radial Vanes
  • Clears large solids
  • Prevents solids from being crushed
  • Reduces casing slurry pressure at the eye of the impeller
  • Reduced power consumption

External Wear Adjustment Screw
  • Four screws for on-line wear clearance adjustment
  • Adjusted while the pump is operating
  • Adjusted six to eight times during the life of the pump

Adjustable Wear Ring
  • Allows a higher percentage of solids pumped and maintained throughout the life of pump
  • Adjusted during operation
  • Reduces suction side recirculation
  • Maintain hydraulic performance

millMAX™ Power Frame
  • Heavy duty cast pedestal
  • External bearing assembly adjustment
  • Wide bearing centers
  • Heavy duty shaft and bearings
  • Double clamp

Reverse Taper Roller Bearings
  • Increases effective load span to improve life
  • Main bearing failure is due to over-greasing
  • Pumping action of taper rollers discharges grease to the outside, preventing ingress of slurry or over greasing of bearing cartridge
