The Sala-series of ST PumpsThe ST-Pump range consists of tough, general purpose Slurry Pumps particularly known for their InducedFlow impellers. The hydraulic design provides a very gentle handling of the slurry. The proven low attrition ofpumped particles has made it the Industrial Standard for Carbon Transfer in Gold Leaching processes.The ”Cloggless” performance of the Induced Flow impellers also makes this product range ideal for allapplications where large or long, stringy solids will be handled.Vertical Torque Flow Pumps Type STGVAVertical wet pit design for pulpy solids andcorrosives. With single suction and no shaft sealingthe STGVA pump offers outstanding design features.Cantilever designThe heavy duty pump shaft moves freely under thebearing housing. There are no journal bearings belowthe liquid level to maintain. The pump has no stuffingbox and thus does not require sealing water.MetallurgyHydraulic parts are available from stock in cast iron andstainless steel and high chrome. Some sizes are alsoavailable with rubber lined or polyurethane wear parts.The pump frame assemblies below the base plate areavailable in carbon steel and stainless steel. Other materials are available upon request.STGVA STHM3.p652Vortex impeller availableThis recessed impeller is located out of the flow pattern.The pumping effect is performed by the vortex that theimpeller generates in the slurry. The passage throughthe vortex pump is fully open, therefore it is especiallysuited for pumping fibres and similar material.Impeller adjustmentEasily adjustable shaft allows setting of pump clearances for maximum performance.V-belt driveThis permits simple cost-effective adjustment of pumpflow rate.Designed for severe pumping‘STGVA’ pumps are designed for severe pumpingproblems of corrosion, abrasion and temperatureextremes in the chemical, minerals processing, pulp andpaper, brewing, food and other industries.08-04-03, 16:13

Product PresentationSTGVA Vertical PumpsHeavy Duty, large cantilevered shaft reduces deflectioneavDututyand provides stable mechanical operation.Simple impeller clearance adjustment from the top ofimpellerclearancancethe pump.Cast Iron bearing housing is piloted in the upper frameIronto assure perfect alignment.Oversized grease lubricated roller bearings are designedersizedto provide up to 60,000 hours of trouble free operation.Grease-purged labyrinth and double V-ring seals effecease-purgedtively eliminate lower bearing contamination.Rigid lower frame minimizes pedestal deflection.N o submerged bearing or stuffing box providessubmergedbearearingvirtually maintenance-free operation.Wet-end available in three different impellerconfigurations. Impellers are keyed onto shaft.Recessed impeller – large clearance between casing andecessedimpellerimpeller – well suited for pumping fibrous slurries(paper stock, wood chips, municipal sludge, etc.), aeratedor frothy liquids (recessed impeller will not air lock) andany application where the pump is required to pass theoccasional large sizes.Fully-recessed impeller in casing providing full flowully-rececessedimpellerthrough capability and provides “gentle” handling of solids in suspension to prevent the degradation of friablesolids (e.g. – carbon transfer in carbon-in-pulp gold recovery process). Also well-suited for handling slurriescontaining high concentrations of stringy, fibrous solids.Available in discharge sizes of 2”, 3” and 4”.Channel impeller – fully closed with large passages suitimpellerable for pumping liquids and slightly abrasive slurries andsludges. High efficiency due to closed impeller design.Available in discharge sizes of 3”, 4”, 5”, 6”, 8”, 10” and 14”.Materials of cconstronstruction – all pumps are available witherialsonstrucuctioncast iron, stainless steel. Some sizes are also available HighChrome, CD4MCU and Elastomer lined wear parts.Dr ive – pumps can be supplied with V-belt drive orivedirect drive configuration.Optional suction pipe – allows additional extension ofoverall length by 1.8 m.STGVA STHM3.p65308-04-03, 16:13

Horizontal Torque Flow Pumps Type STHMThe STHM pumps are also available with alternativeimpeller designs which allow optimum adaption todifferent media - from heavy suspensions to cleanliquids.Pumping partsVortex or channel impellerMotor bed plateVortex impeller for heavy suspension and liquid/gasmixture. Channel impeller for light suspensions andclean liquids.Overhead motor bed plate gives compact installationwith extra motor protection and simple belt tensioning.V-belt driveThe vortex impeller is recessed in the back of the pumpcasing, giving a free passage through the casing. Thepump can normally pump anything that can passthrough the connecting pipes.This permits alteration of the pump’s performance without opening the pump.Bearing assemblyStandard pumping parts in cast iron, stainless steel, highchrome and some sizes in Polyurethane or rubber lined.Other materials are available upon request.Vortex impellerCartridge type with grease lubricated roller bearingsdesigned for more than 60 000 operating hours.Shaft sealStandard stuffing box with seal water. Optionalmechanical seals.STGVA STHM3.p65408-04-03, 16:13

FeaturesProductandPresentationbenefitsSTHM Horizontal Pumps1. Fabricated steel base is fully machined to provideperfect alignment and concentricity.2. Large diameter oversized shaft minimizes deflectionand provides smooth running, stable operation.3. Simple impeller clearance adjustment from drive sideof pump.4. Heavy duty grease lubricated roller bearings enclosed in a cartridge type bearing housing.5. Overhead motor plate for V-belt drive operationminimizes space requirements (side by sidebaseplates or common baseplate for direct drive alsoavailable).7866. Grease purge labyrinth and double V-ring seals prevent the ingress of dirt and liquid into thebearing house.7. Conventional packed stuffing box is standard.Mechanical seal available as an option.8. Impeller configurations identical to STGVA verticalpumps – i.e. recessed, fully recessed or channelimpeller. Casing and impeller are interchangeablebetween identical sizes of vertical and horizontalpumps.534218Channel impellerSTGVA STHM3.p6558Fully recessed Impeller08-04-03, 16:14
