Slurry Pump1.2.4Long-term field storageMinimum requirement for storage and maintenance of centrifugal type pumps on sitebefore their installation and start-up.1.Medium term storageIndoor storage of equipment is recommended in order to prevent the harmful effects ofexposed conditions, particularly in dust laden atmospheres.The standard anti-rust protection provided prior to dispatch remains adequate for periodsnot exceeding two months.Whenever indoor storage is not possible, it is necessary to follow the guidelines givenbelow:a)Locate the pump set with its bedplate on a concrete floor and supported onwooden joists of approximately 100 mm x 100 mm (4” 4”) in section.b)Cover the pump set, whether located indoors or outdoors, with a strong,waterproof cover extending down to the baseplate. The cover must be securelyfixed to withstand ambient weather conditions.c)Prior to securing the cover, ensure that:i)ii )all openings, including inlet and outlet apertures, are properly sealed, and;the bearing cylinder and drive are properly protected against dust.2.Prolonged storage -up to 2 yearsThe following steps are essential in all cases where prolonged storage is foreseen:a)The pumps are to be adequately warehoused in a closed dry and, if possible, atemperature controlled building.b)Every six months, the stuffing box/shaft seal sleeve area should be inspected,cleaned and re-coated with a suitable anti-rust compound, if required.c)If disassembly of the pump is not practical then proceed as follows:i)ii )iii )Thoroughly dry the pump case with hot air at 35 C to 65 C (95 F to 149 F).Seal all pump openings and attach sachets of hygroscopic salts (silicagel).While drying with hot air, ensure that no other parts become overheatedas this may be detrimental.d)The pump rotor should be turned over several times by hand at intervals notexceeding one month.e)The bearing grease should be checked at least once every twelve months.f)The bearing cylinder must be disassembled, cleaned and regreased prior toreassembly at least once every 24 months.WH03AAEAAA0us 03a.docxJANGeneral4/6
Slurry PumpDuring prolonged storage, it may prove difficult to rotate the pump rotor manually fornormal maintenance. In such cases proceed as follows:a)Loosen the bearing end covers which limit the axial displacement of thebearings.b)Move the pump rotor along its axis, thus freeing the assembly and allowingmanual rotation.3.Storage in excess of two yearsFor prolonged storage in excess of two years in adverse ambient conditions, specialprotection may be necessary. Any moisture absorbing devices used must be absolutelyeffective and regularly maintained. Whenever possible for storage periods in excess of twoyears, it is recommended that all pump components are disassembled, washed, dried,protected and reassembled afterwards. This work may be done by Metso Minerals andcharged to the purchaser under normal rates in force at the time the service is carried out.1.2.5Storage of sparesIn general, unless otherwise instructed, keep all spare parts in a cool, dry environment andprotect rubberised/synthetic components from sunlight and high voltage electricalequipment.Rubber is affected by ageing and its rate of deterioration is dependent on the type ofrubber and the storage conditions. Rubber perishes most rapidly when exposed to heat,ultra violet light and oxidants, the more commonly overlooked sources of which aresunlight and electrical machinery. Rubber can become permanently deformed ifcompressed out of shape during storage. Mineral oils, solvents, dust, contact with metalsand moisture can also damage rubbers depending on type.WH03AAEAAA0us 03a.docxJANGeneral5/6
Slurry PumpTo ensure rubber products maintain their original properties, storage conditions must becontrolled. Where practicable, ensure rubber products are:1.kept sealed in their original packing which should be opaque;2.kept away from direct sunlight;3.kept away from electrical machinery -e.g. motors and generators;4.kept in a cool, dry environment between 15 C to 25 C (59 F to 77 F);5.stored away from exhaust fumes;6.stored separately from chemicals and fuels;7.stored loosely packed;8.rotated on a first in - first out basis.Storage life for different types of rubber stored under recommended conditions is asindicated in Table 1.2.5-1.At 15 C (59 F) the storage life will be about double and at 35 C(95 F) about half of that stated in the table.Type of rubberProduct ref.Storage life @ 25 C (77 F) IR7Ethylene-propyleneEPDM10Chlorosulphonated polyethylene(Hypalon)CSM10Table 1.2.5-1 Types of rubber and their expected storage life.WH03AAEAAA0us 03a.docxJANGeneral6/6

Slurry Pump2.2ApplicationsThe Metso Minerals Slurry Pump has been designed for a wide variety of abrasivepumping duties. While the pumps may be used in many different industries, they are alldesigned for constant use in the most arduous conditions. These high-efficiency pumpsare of a simple design, providing ease of maintenance and facilitating replacement ofwearing parts.2.3Design2.3.1GeneralSlurry Pumps are made up of four basic modules, the frame (A), the bearing cylinder (B),the shaft seal (C) and the wet-end (D) assemblies – see Figure 2.3.1-1.A comprehensive range of modules are available, to configure pumps to suit a wide rangeof applications.Pumps are supplied bareshaft or as fixed-base pumpsets with various choices of motormounting position. Manual or hydraulic slide-bases are optional.Maximum efficiency is maintained by setting impeller running clearance(s). The adjustmentis easily carried out during maintenance and shut-down periods.Standard bearing cylinders are grease lubricated, but oil lubricated bearings are an option.Pump designation is made up of letters which identify the range and numbers whichindicate the inlet diameter in millimetres –e.g. HM150.CDBAFigure 2.3.1-1 Typical outline design of Metso Minerals Slurry Pumps showing the basicpump modules: Frame (A), Bearing cylinder(B), Shaft seal(C), Wet-end (D)WH06AAAAAA0us 05a.docxJANDescription3/4
Slurry Pump2.3.2Noise levelIn certain installations and outside the optimum operating conditions, the noise level of 70dB(A) may be exceeded. The motor generates most of the noise and, in general, thenoise level for properly designed installations will be about 2dB(A) above that of the motor.2.3.3VibrationThe international standard ISO 10816-1 is valid for all slurry pumps.When the pump is new, the vibration level at any bearing should not exceed 4.5 mm/s(0.17 in/sec), if the pump is fixed to foundation. If the pump is installed on slide base, thevibration should not exceed 7.1 mm/s (0.27 in/sec).Vibration levels above 4.5 mm/s (0.17 in/sec) should always receive attention.Should vibration levels exceed 11 mm/s (0.43 in/sec), stop the pumpimmediately.Common reasons for high vibrations are:inadequately tightened fasteners;slack V-belt;misalignment of the drive;the pump impeller is blocked by debris.WH06AAAAAA0us 05a.docxJANDescription4/4

Slurry Pump4DESCRIPTION OF OPERATION4.1GeneralCentrifugal pumps work best with minimum wear and other mechanical stress if theoperating point is close to the pump's best efficiency point (BEP). To choose a pump thatworks close to its best efficiency line (BEL), it is important to understand how the pumpinteracts with the piping system in which it is installed.In simple terms, a pump and its piping system act as two communicating vessels. Thepiping sysem has a resistance curve that starts at the delivery static head (SH), at zeroflow. As the flow increases, the resistance increases with pipe friction. A radial centrifugalpump has a descending discharge/flow curve for each rpm. The pump's operating point(DP) at a given pump speed is the point of intersection between the piping system'sresistance curve and the pump's discharge/flow curve. See diagram below.To obtain the best wear properties the pump can beprovided with different materials in the parts exposedto the greatest wear.4.2HDPRPMPIPINGSHIt is therefore important to calculate the piping system'sresistance curve correctly and to take into account themanner in which the admixture of solid particles, forexample, affects the curves of the piping system andpump. We recommend using Pumpdim forWindows for our pump applications.QBest efficiency pointPressure conditions in the pump casing are shown in Figure 4.2-1. At the BEP there iseven pressure round the impeller, resulting in small radial forces which in their turn exertlittle load on bearings and cause little shaft deflection. When the pump operates at lowcapacity and not at BEP, differential pressure builds up over the casing volute. This givesrise to a radial force F on the impeller which is a function of the differential pressure (Pa,psi) and the impeller's projected area (mm2, in2).WH14AAAAAA0us 07a.docxJANDescription of operation1/4
Slurry PumpFFBEPQWhen the pump operates atbest efficiency point, uniformpressure is obtained in thecasing which in its turneliminates radial forces onthe impeller.When the pump's flowcapacity is not utilized,uniform pressure in thepump casing will not beobtained and this results ina radial force F on theimpeller.The magnitude of the radialforce F is greatest when thepump runs against closedvalve 0 flow. The forcesubsequently diminishes upto BEP where it is close tozero. At flows above BEP theforce changes direction.Figure 4.2-1 Best efficiency pointWhen the pump is not operating at BEP the bearings will have a shorter service lifebecause of higher radial bearing loads projected onto the bearings. In addition, thedifferential pressure over the impeller gives rise to the circulation of slurry between theimpeller and the inlet liner, causing rapid wear of the liner.4.3Hydraulic effects of operation at, and outside, BEPImpeller vane inletPump casing nose12Figure 4.3-1 Operating at best efficiency point1. The slurry's inflow angle coincides with the impeller's vane angle and no erosivevortices occur.2. The slurry's flow angle harmonizes with the angle of the pump casing nose and noerosive vortices occur.WH14AAAAAA0us 07a.docxJANDescription of operation2/4
Slurry PumpThe way in which the hydraulic work is affected when the pump does not operate at BEP isshown in Figure 4.3-2 and Figure 4.3-3 This is of decisive importance in slurry pumping.Impeller vane inletPump casing nose3546Figure 4.3-2 Operating outside BEP - At low load3.4.5.6.Abrasion on the impeller vane's pressure side.Vortices occur on the vane's vacuum side.Vortices.Abrasion caused by particles striking and bouncing against the surface.Impeller vane inletPump casing nose79810Figure 4.3-3 Operating outside BEP - On overloading7.

Abrasion on the pump casing nose.WH14AAAAAA0us 07a.docxJANDescription of operation3/4
Slurry PumpHydraulic efficiency is a function of hydraulic turbulence - the more turbulence, the lessefficiency. In slurry pumping, a high level of efficiency is therefore important.Little hydraulic turbulence is formed at BEP and the abrasion is chiefly of a sliding nature,since the differential pressure is low when the slurry passes through the impeller andpump casing. The rate of abrasion is low and the wear is spread evenly over the surfaces.The rasping wear or high-pressure wear that occurs between the impeller and suction sideliner is lower, since the evenly distributed hydraulic pressure reduces recirculation.When the full capacity of the pump is not used and its efficiency is less than at BEP,hydraulic turbulence occurs and the solid particles in the slurry strike and rasp the impellerand pump casing. This causes local wear damage and the service life of thesecomponents is severely shortened. At the inlet to the impeller the slurry's flow angle is notthe same as the pump vane angle, which gives rise to turbulence and results inrecirculation of slurry in the channel. At the pump casing nose the flow from the impellerdoes not harmonize with the shape of the casing, causing turbulence to occur immediatelyafter the pump casing nose.In the worst case, oversized pumps which do not operate at BEP result in bearingbreakdown, shaft fracture and unevenly worn inlet and pump casing liners with deep wearmarks at the casing nose.4.4Choice of pump sizeFor preference, choose the pump size which operates as close as possible to the pump'sbest efficiency point (BEP).WH14AAAAAA0us 07a.docxJANDescription of operation4/4
