Every jam cost 90 minutes' production, with an entire in-line operationstalled. Production also suffered from continual minor problems.Watson-Marlow peristaltic pumps have no valves to clog and can handlesuspended solids, so they need no filters, and simple, planned maintenance.A one-minute tube change at extended intervals avoids production linestoppages.
Where are our 1 million pumpskeeping industry productive?Watson-Marlow pumps save time and moneyworldwide by successfully handling the toughestapplications in a broad range of industries including• Chemical metering and transfer:corrosive acids and bases• Water and waste water treatment:sodium hypochlorite, hydrofluorosilic acidand ferric chloride• Paint and pigments: dispersion millfeed, pigment and latex transferAt a remote water treatment works, chemicals are metered to balance pH levels• Pulp and paper: dyes, brighteners, sizing agents,retention aids and titanium dioxide• Mining and mineral separation:reagents, polymers and floccullants• Construction: cement, brick and rooftiles; metering and spraying of colorants,coatings and additives• Brewing: metering and transfer ofyeast, flocculants, stabilisers and finingsIn a difficult lacquer handlingapplication, close coupled pumpssaved time and moneySodium hypochlorite causesgas locking problems in manyother pump types• Printing and packaging: varnishes,inks, coatings and adhesives, withno colour cross-contamination or aeration• Food and beverage: Clean-in-placeapplications, dairy, bakery, flavouringsand additives• Textiles: fibre coatings, dyes and acids• Fine chemicals production: meteringof process chemicals• Engineering: spray coating and waste recovery• OEM: versions available for system suppliersIn an aggressive chemical recovery application, the pump paid for itselfin less than 12 monthsPutting diaphragms into the shadeAccurate and repeatable metering ofprocess fluids into dispersion mills iscritical in achieving uniformity fromone batch of paint pigments to another.Because of their ability to provide consistent,reproducible flows at low volumes, Watson-Marlow peristaltic pumps were chosento replace double diaphragm pumps at BASF'sMichigan paint mixing plant.The pumps require minimal set-up time andmaintenance. The sealless design eliminates theneed to clean the pumps, thereby avoiding thecosts, health risks, and environmental issuesassociated with cleaning solvents.“It is essential for colour consistency that flowrates to the mills be stable and reproducible,”says the production manager. “The doublediaphragm pumps we had been using wereapt to stall at low flow rates. We no longerhave that problem since we installed theWatson-Marlow peristaltic pumps.”5
PUMPS FORINDUSTRYThe perfect pump: which one is right for you?How to pick aWatson-Marlow’s tough industrial casedpumps are a team, and they’re on your side.520, 620 and 720, using continuous tubing orelements, cover flows from 4µ/minto 4,000 litres/hour, with high accuracy andindustrial compatibility.The 720 is a powerful pump which canbe fitted with one or two pumpheads: twinchannels double the flow for high-flowmetering or transferThe versatile, medium-flow 620 is availablewith two rollers, for maximum throughput,or four rollers, for minimum pulsation.Other pumpheads are availableWith its eight tubing sizes, the 520 rangehas a flow ratio of 875,000:1, giving superbcontrol. As well as standard metering duties,the 520 offers specialist pumping such asmulti-channel and minimal pulsationNo simpler maintenanceMaintenance costs, in cash anddowntime, are unavoidable for all pumps– except peristaltic pumps. Stators androtors wear, valves jam, gas causesbreakdowns – every one cuttingproduction. Peristaltic pumps neednew tubes at long, predictable intervals.Changing them takes moments –truly, one-minute maintenance.The same principle applies to 520,620 and 720 pumpheads:1: Open the tool-unlockable safety guard(or track); remove the old tube or element, helpedby ergonomic features such as the 520’s clutchedrotor and the 620’s retractable rollers2: Fit another tube or element3: Close the guard; and (if you have anelement model) connect up to your system6

He tried centrifugal pumps, but poor flowcontrol led to inconsistent colouring.Then he bought a Watson-Marlow 720 series pump. The slurry remaineduniform and could be applied in precise quantities. Since the fluid iscontained within the tube, the pump cannot clog. in addition, the pump issmall enough to be conveniently set up in various parts of the factory, andits impervious casing protects the pump in a very messy environment.13

TUBINGTECHNOLOGYSelect the tubing for your applicationAt the centre of all Watson-Marlow pumps is a range of abrasion-resistant tubes and elementsavailable in chemically stable materials including Marprene, Style 400, STA-PURE PCS,STA-PURE PFL, Pumpsil and Neoprene.Choosing the best tubing for your applicationSelecting the right tubing is as important as the choice of pump. The best way to select a tube material is to check the fluid tobe pumped against those listed in our chemical compatibility guide, via the website or request a printed copy of the guide.• For maximum tube life use a large bore tube at low speed.• For maximum flow rate use the largest bore size tube at maximum speed.• For maximum accuracy use a small bore size tube at high speed.Suction lift depends on the tube restituting fully before the advance of the next roller. If this does not occur, the flow rate will bereduced. For maximum suction lift, use the smallest practicable bore size of tubing and run the pump at the slowest speed.MarpreneSTA-PUREPCSSTA-PUREPFLPumpsilNeopreneStyle 400Up to 10,000 hourspumping life••••Wide chemical resistance•••High pressurecapability (0-7 bar)••••Additional abrasionresistance•High dispensing accuracy•••Low gas permeability••LaserTraceability•Meets or exceeds USPClass VI requirements•••Tubing immersion samplesA tubing sample pack is available which contains the full range of materials forchemical compatibility testing. For critical application, we recommend thatcustomers carry out an immersion test using the duty fluid and the intendedtubing material. A short length of tube is immersed in the duty fluid for a period of48 hours and then examined for signs of swelling, embrittlement or deterioration.To request a tube sample pack please order 999.0001.00019
TUBINGTECHNOLOGYSelect your tubeChoosing the PERFECT tubefor all of your applicationsWatson-Marlow is the only peristaltic pump manufacturer in the world to manufacture its owntubing, optimising our tubing tolerances and formulation to deliver the best process pumpperformance. In a peristaltic pump, the tubing largely dictates pump and system performance:Its restitution creates suction, its strength resists pressure, its flex resistance determinespumping life, its bore defines the flow rate, its wall thickness controls pumping efficiency andits purity protects your product from contamination. Watson-Marlow offers tubing in eightmaterials and over 40 sizes, giving an extraordinary range of chemical and applicationcapability.Marprene is our highperformancegeneral-purposetube. This thermoplasticelastomer provides chemicalcompatibility, long pumping lifeand pressure handling. Marprene ®is ideal for general-purpose pumpingor food handling and is highly resistant tooxidising agents such asozone, peroxides and sodium hypochlorite. Meets FDArequirements 21 CFR 177.2600 and USDA standards forfood handling. Working temperature range 5C to 80C.Autoclavable.GORE High ResilienceTubing Style 400is an expanded PTFE andViton fluoroelastomer and enables the benefits of peristalticpumps to be introduced to a wide range of applications forpumping concentrated acids like sulphuric and nitric acid,as well as aromatic hydrocarbons like toluene and xylene.Style 400 tubing offers tube life morethan 50 times that of extrudedViton or Fluorel tube and can beused for pumping up to 4 bar.The elastomer used in thistubing is Viton GF-600S, aperoxide-cured fluoroelastomerbased on DuPont's advancedpolymer architecture.Secure linking upWatson-Marlow tubing elements for 520,620 and 720 pumps link to the rest of yoursystem using secure instant connectors: industrialstandardCam-and-Groove connectors for 620 and720, left; and quick-release push-fit connectors for 520pumps, above.
