WARMAN® Centrifugal Slurry Pumps Excellent Minerals Solutions MC Mill Circuit Duty Warman MC mill circuit duty slurry pumps are designed for the most aggressive duties and provide excellent wear life and reliability. Hydraulic experience and latest material technology make Warman MC the best choice for mill circuit applications Warman MC pumps are specifically designed for the most severe slurry applications such as ball and SAG mill cyclone feed plus water-flush crushing in mineral processing plants. They easily manage large size par- ticles in dense abrasive slurries and are well suited for use as slurry transfer pumps on arduous applications such as gravel dredging or coarse coal cyclone feed. MC pump hydraulics are based on more than 25 years of fundamental and applied research and backed up by wear performance field trials. Unique design and wear evaluation software ensures high efficiency and optimum life. Warman MC designs incorporate the latest in hard alloy and elastomer technology, extending wear life in highly abrasive and corrosive slurries. The MC range is engineered to enable different material combinations MCR pump – elastomer liners inside ductile iron outer casing with metal impeller and metal or elastomer throatbush and frame plate liner insert MCU pump – all metal unlined hard white iron casing with metal impeller, throatbush and frame plate liner insert MCM pump – hard white iron metal liners inside ductile iron outer casing with metal impeller, throat- bush and frame plate liner insert • Large diameter, low speed, high efficiency impellers • Latest wear resistant materials • Interchangeable elastomer or metal liners, or unlined metal • Simple “full face” side liner adjustment • Self centering stuffing box design • Fast “one-piece” wet-end changeout on larger sizes • Available reverse rotations offer plant design flexibility Warman 400 MCR reverse rotation Left: Chile’s large copper plants continue to improve their instal- lations. A 550 MCR pump has replaced a North American manufacturer Middle: 450 MCR installed at a gold plant in North America Right: Copper gold installation in Australia using the 550 MCR pump Lined or unlined mill pump options ensure the optimum cost solution for your application The outer casing of the lined MCM all metal pump ensures slurry containment and allows a safe shut- down in the event of a cracked liner. This provides a low risk alternative to plants concerned with casing breakage due to mill ball overflow. The unlined MCU metal range perfectly fits duties such as dense media circuit applications in the coal washing industry. Very thick metal casings, an impel- ler design for larger particle passing, and the “full face” adjustment feature ensure extended life with coarse coal slurries. With the range of designs available, the MCU can be used in even the largest of the new high capacity coal washing plant installations. The MCU design also lends itself for use in gravel pumping type applica- tions. Longer wear life and lower operating costs are ensured.

In trial after trial, Warman elastomers have outperformed all competi- tors’ cast metal pumps. The advantages are many as Warman MCR elastomer liners: • handle coarse particles and last longer • handle ball scats with ease • are lighter in weight and safer for maintenance • are less expensive than heavy metal parts So whatever the preference – for a rubber or metal pump – the Warman MC pump will ensure the best wear life and operational safety. Right: Three Warman 550 MCR mill circuit pumps in stalled at a copper mill along with Cavex hydro cyclones, Isogate slurry valves, and Vulco wear resistant rubber lined tanks, piping, hoses and spools Warman MC pump’s unique design allows interchangeability of materials to optimize wear life Only one pump manufacturer allows operators the flexibility of all-metal or all-rubber lined or a combination of both The MC is the only pump for mill circuit applications that has interchangeable materials from a wide range of hard alloy and compression molded elastomers. This enables optimum materials selection for each specific application ensuring the wear characteristics for each component are balanced. Warman MC mill circuit duty slurry pump has a number of unique features Reduced recirculation is achieved by the deep expel- ling vanes on the front of the hard alloy impellers. Expelling vane tip turbulence is minimized by the pat- ented extended shroud feature that traps tip vortices and prevents localized scouring on the throatbush face. Internal liners can be fully worn before replacement as the split outer casing provides structural integrity and high operating pressure capability and safety. Split cover and frame plates allow easy access for replacement of the impeller and throatbush. Two-piece coverplate on 400 MCR/MCM and larger for easy access to impeller, stuffing box, or complete inspection. MCU ductile iron suction cover MCU hard white iron casing MCU ductile iron frame plate MCR elastomer cover plate liner MCR elastomer frame plate liner MCR ductile iron frame plate “Full face” adjustment extends wear life In addition to deep expelling vanes on the impeller, adjustable throatbush and frame plate liner insert are necessary to maximize part life. As slurry moves through the throatbush-impeller gap from the high pressure at the impeller periphery to the low pressure of the impeller eye, local high velocities can cause wear at the face or around the impeller eye. The Warman MC’s “full face” adjustment feature extends wear life by minimiz- ing the impeller-throatbush gap across the whole face of the throat- bush. This provides gradual pressure reduction and minimal recirculation so any possible wear is distributed evenly, unlike sacrificial wear rings used by some manufacturers at the impeller eye that may focus wear and cause premature failure. The “full face” double adjustment for throatbush and frame plate liner insert is easy to perform, even during operation, ensuring long liner life and optimum efficien- cy. Once clamping screws are released, adjusting screws can be rotated sequentially to move the liner closer to the impeller face. The “full face” adjustment feature allows the liner to move closer to the im peller face to minimize the impel- ler-throatbush gap adjustable impeller-throatbush Center row: Parts in common to both the MCU and MCR and material options, from left to right – elastomer or hard white iron throatbush; hard white iron impeller; elastomer or hard white iron frame plate liner insert; adjustable stuffing box; base and bearing assembly two-piece cover plate consisting of MCR ductile iron cover plate and suction cover (400-850 MCR) “One-piece” wet end changeout ensures minimum mill downtime Larger MC pump wet ends can be changed out and replaced as “one-piece”. By adjusting the throatbush and frame plate liner inserts tight against the im peller, mounting bolts can be removed, the impeller can be unscrewed from the shaft and the outer casing, liners and impeller pulled off as “one-piece”. Impeller and liner inspection can then be completed at a more convenient time in the workshop. Stuffing Box Centering Adjustable stuffing box allows for centering of the stuffing box and lantern restrictor to the shaft sleeve. This may be adjusted after piping loads have been applied to the pump to compensate for associated casing displacement. Left: Orange centering tool pins align stuffing box to the sleeve Above: A new innovative quick change procedure has been de veloped for faster removal of the larger MC range pump wet ends. A 650 MCR wet end being removed in Santiago, Chile MC features save time and money Easily adjustable throatbush allows maintenance of the impeller seal face clearance without the need to adjust bearing assembly or drive. Easily adjustable frame plate liner insert allows main- tenance of the drive side clearance and shaft sealing performance to protect the stuffing box. Large, open internal passages reduce velocities thus reducing wear. A large diameter shaft with the shortest possible over- hang and heavy duty roller bearings housed in a removable bearing cartridge extends bearing life. Large diameter, low speed, high efficiency impeller manufactured from a range of abrasion resistant alloys provides increased wear life. Patented shrouds that extend past the periphery of the impeller and expelling vanes provide improved flow and reduced wear at the expelling vane tips. Left: Rubber throat bush and frame plate liner insert shown in upper section; metal throatbush and frame plate liner insert shown in lower section Patented casing profile with more material in areas of high particle impingement gives increased wear life. Impeller release collar facilitates impeller removal. Reversible casing (400MCR and larger) allows the discharge orientation to be either “right vertical” posi- tion (standard) or “left vertical” position, giving great- er flexibility to the plant layout designer. The only additional parts required to effect the changeover are the clockwise rotation impeller and shaft. one-piece bearing housing large diameter shaft large, open internal passages impeller shrouds with deep expelling vanes self-centering stuffing box large diameter, low speed, high efficiency impeller easily adjustable throatbush easily adjustable frame plate liner insert impeller release collar Product information software developed by Weir Minerals Pump Technology Center Weir Minerals product information software is avail- able on CD from the local sales office or for download at weirminerals.com.
