Slurries generally behave the same way as thick, viscous fluids, flowing under gravity, but also pumped as needed. Slurries are divided into two general categories: non-settling or settling.

Non-settling slurries consist of very fine particles, which give the illusion of increased apparent viscosity. These slurries usually have low wearing properties, but do require very careful consideration when selecting the right pump because they do not behave in the same manner as a normal liquid does.

Settling slurries are formed by coarse particles that tend to form an unstable mixture. Particular attention should be given to flow and power calculations when selecting a pump. The majority of slurry applications are made up of coarse particles and because of this, have higher wear properties.

Below are common characteristics of slurries:

• Abrasive
• Thick consistency
• Can contain a high amount of solids
• Usually settle quickly
• Require more power to operate than a “water” pump

SLURRY PUMP SELECTION

Many types of pumps are used for pumping slurries, but the most common slurry pump is the centrifugal pump. The centrifugal slurry pump uses the centrifugal force generated by a rotating impeller to impact kinetic energy to the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.

Slurry applications greatly reduce the expected wear life of pumping components. It’s critical that pumps designed for these heavy-duty applications are selected from the start.

With small vertical sump pumps is it possible to hang the pump in the sump by the lifting bracket provided. Larger units are normally bolted to a permanent base plate. Pump bearings are in a housing above the base plate for accessibility and protection.

All pumps can run dry intermittently. Pumps with metal pump parts can run dry for an unlimited length of time. Special designs giving extended length, with the bearings below the base plate, are available on request.

2.ROBUST DESIGN

The heavy-duty pump shaft is of cantilever design, hanging below the bearing housing. There are no submerged bearings, stuffing box or shaft seals. This design ensures minimum maintenance and eliminates the need for water flushing.

The pump shaft is mounted in grease lubricated roller bearings. Impeller clearance is maintained by external axial adjustment of the shaft/bearing assembly. Bearings have double seal protection against contamination.

3.HIGH-QUALITY PARTS

Standard pumps are supplied with parts in wear resistant natural rubber or High Chrome white iron alloy, with a nominal hardness of 600 BHN. Other wear part materials available include elastomers in synthetic rubbers and polyurethane and metals such as 316 stainless steel and CD4MCu. Parts in different materials are fully interchangeable and can be combined for optimum life.

4.WET END

The “wet end” parts have large material sections for extra-long wear life and are designed for the toughest of applications. Single volute and generous solids passage through the pump ensure safe and clogless operation. The “wet end” assembly is suspended from a tubular column below the bearing housing.

5.DRIVE

Pumps can be supplied with a V-belt drive, motor and drive guard. The motor is mounted vertically on an adjustable motor plate fitted beside the bearing housing.

6.MOTOR SIZE

Motor size and V-belt drive vary with the pump application. Minimum data required for an approximate pump, speed and drive motor selection are:

• Slurry flow rate
• Slurry density
• Total discharge head

The Mission MAGNUM I has been engineered for the toughest jobs in drilling, production, well-servicing, and industrial applications.
The revolutionary design of the MAGNUM I provides supreme-duty performance in all types of fluid pumping operations. Although it offers greater capacity and higher heads, the MAGNUM I remains the competitive pump of choice for aggressive applications.
The MAGNUM I is more powerful, more durable, and easier to maintain than any conventional pump in use today.

The Magnum has an open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The Magnum is available in Magnachrome, hard iron, stainless steel, and aluminum bronze fluid ends. The pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration).
Typical Applications

• Barite, ferric oxide, and mineral oil
• Base drilling muds
• Glass fibers
• Sugar processing
• Ash or coal conveyers
• Cement
• Mine de-watering
