surMAX™ THE BEST CHOICE FOR FINE PARTICLES ABRASIVE SLURRIES

Following the dramatic success of the micMAX™ metal slurry pump, We has incorporated the designed features into a new surMAX™ rubber lined pump product range.

The advanced feature has an externally adjustable wear ring that closes the suction side impeller clearance between the suction liner and the eye of the impeller.

This clearance eliminates the problem conventional rubber lined pumps experience – that of pressure pulsations caused by the close proximity of the rotating raised expelling vanes to the suction liner, necessary to maintain ﬂow, and subsequently generating heat in the liner and rubber devulcanization failure.

The ability to control the suction side clearance reduces the hydraulic recirculation and therefore contributes to maintaining the design ﬂ ow over the life of the pump, increasing the life of the impeller.

HEART OF DESIGN $E:\MINECO\WEBSITE_MINECO\Page 1_Slurry Pumps\pumps pictures\slurryMAX.jpg$

RUBBER LINED CASING – The extra-thick rubber lining has rigid reinforcement to prevent collapse onto the rotating impeller under upset vacuum conditions. High pressure casings are available for applications requiring multiple pumps in series.
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. Impellers are oversized in diameter and available in metal or elastomers.
POWER FRAME – heavy duty cast iron pedestal with external bearing assembly adjustment mechanism. Drilled for overhead motor mounting assembly.
FLANGES – loose intake and discharge flanges drilled to suit various pipe requirements.
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.

THE KEY ADVANTAGE TECHNOLOGY:

High-chrome impeller is resistant to “tramp” metals and is capable of higher tip speeds. Tight clearance between wear ring and impeller reduces suction-side slurry recirculation by up to 95%. Pumps feature a patented, adjustable, suction-side, sealing system that features a wear ring that runs against the machined face of the impeller near the eye.
Wear ring can be adjusted up to eight times throughout the life of the wet-end parts and is adjusted while the pump is running.
Generous clearance between impeller and suction liner limit the cyclical wear of the rubber associated with the trapping of solids between the liner and the impeller.
Radial impeller vanes both “clear” solids and reduce pressure at suction-side clearance – reducing solids grinding and recirculation respectively.
Tight back liner clearance maximizes packing and shaft sleeve life – normally this clearance is opened up as impeller wears and needs adjusting.

micMAX™ – PERFECT SLURRY PUMP FOR MOST ABRASIVE SLURRIES

micMAX™ severe-duty slurry pumps have a unique design developed for grinding mill discharge duties and other abrasive slurries.

Mineco offers wet end conversions or complete pump assemblies to meet customer desires and demands.

The micMAX™ pump features a patented on-line wear clearance adjustment, which minimizes cost per ton pumped compared to conventional hard metal and rubber lined pumps through:

- Increased Wear Life
- Lower Power Consumption
- On-line Wear Clearance Adjustment
- Increased Mill Throughput
- More Consistent Hydrocyclone Separation
- Less Downtime

CASING – designed for minimum slurry turbulence and even wear. Includes (14×12 and smaller) 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 – designed for close clearance at the back (14×12 and smaller), or SUCTION LINER with integral wear ring (16×14 and larger). 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.
FLANGES – loose intake and discharge flanges drilled to suit various pipe requirements.
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.

ceralMAX™ – PUMP DESIGNED FOR ABRASIVE SLURRIES WITH LARGE SOLIDS

Efficient pumping in aggressive applications

Why sacrifice wear life to pump the largest solids and most abrasive slurries? This is the question we asked which lead to the development our heavy-duty ceraMAX pump. With large internal clearances and a wide impeller, our ceraMAX presents the ideal solution to optimise passing size, efficiency and wear life.

$E:\MINECO\WEBSITE_MINECO\2_SLURRY PUMPS_03 pages\Capture7.JPG$

ceraMAX™ benefits of our optimized design

Many slurry pump applications in coal, dredging and hard rock mining require the ability to pump large solids. Traditionally, operations used open impellers or extremely oversized pumps to get the job done – at the cost of ineffective performance. Our ceraMAX is designed for high efficiency, and long wear life and tackles the most abrasive slurries.

Pumps large and abrasive solids

A wide diameter impeller and increased cutwater clearance allows for the passing of large solids. The addition of the wear ring feature provides a large clearance between the impeller and suction side to ensure solids are not ground up in the pump as they would be with conventional designs.
