  28. 28. 7 minute overview - Verderflex
  29. 29. Who is Verderflex? – Largest Peristaltic Pump Manufacturer in the world • Smallest size is 5mm ID • Largest size is 125mm (5”) ID – Leader in product innovation • Dura product line • Smart tubing pumps – Superior Hose life • Longest lasting in the industry • Color-coded for easy recognition
  30. 30. Advantages of Peristaltic Pumps • Abrasion resistant – Hose life is not related to a product’s abrasive qualities – The hose fails due to fatigue or chemical action, not abrasion • Solids Handling – Able to pump liquids containing up to 80% fine inorganic solids (Slurry) – Up to 10% sludge capabilities • No moving parts in the liquid stream – No contamination of product, pump or gearbox – No metal to metal contact – Smooth liquid passage (no valves, dead corners, or mechanical parts)
  31. 31. More Advantages • Self priming / Dry Priming – Up to 95 % vacuum or 31’ lift of water • Dry-Running – The hose is lubricated from the outside – Able to pump air or products that “off-gas” (NaOCl, Yeast) • Reversible rotation – The pump can be used to empty lines or clear blockages • No internal backflow – Accurate Dosing (true positive displacement) – Rotary pinch valve – repeatability ± 1%
  32. 32. More Advantages • Shear sensitive products – Suitable for handling Flocculent/Coagulant, Polymers – Product is not damaged, Process Performance Improved • Easy maintenance – Low cost of ownership (hose is only wearing part) – Easy and completely cleanable without disassembly – Reduced down time (maintenance in place)
  33. 33. Pump Terminology
  34. 34. Hose Pumps vs Tubing Pumps
  35. 35. Tubing Pumps • Capacities range from 0.25 gph – 7 gpm • Discharge pressures up to 30 psi • Many consist of integrated drive units with built in controls (420mA, RS232) • NEMA 4 washdown enclosure • Use non-reinforced extruding tubing – Verderprene, Silicone, Fluoroelastomers (Viton, Chem-sure) • Tubing life ranges up to 50006000 hours depending on material & pump speed
  36. 36. Hose Pumps • Flow rates from .05gpm – 395gpm • Pressures up to 232psi across full range • Uses Nylon-reinforced hose to achieve pressure • Four Basic Hose materials, one size per pump (range from 5mm ID to 125mm ID): – Natural Rubber – EPDM – Buna – Hypalon • Hose life generally lasts 2000 hours, depending on application details • Speed is key – slower is better!
  37. 37. Pump Selection / Pump Sizing
  38. 38. Key Questions to Ask • What am I pumping ? – Affects the chemical resistance of the hose type and inserts • How am I operating the pump ? – Intermittent or continuous duty – Hose life and / or a smaller pump • What is the product temperature ? – Limits hose type, hose life or pump size
  39. 39. Key Questions to Ask • What is the discharge pressure and flow rate ? – Pump type, power requirement and pump speed • What is the length of the suction and discharge lines ? – Determines impulse and friction losses • What is the product’s working viscosity ? – Determines friction loss – Adequate NPSHa? • What fittings do I need ? – ANSI flanges, threaded NPT, etc.
  40. 40. How Do I Size A Pump ? • A pump’s capacity is determined by : a) The hose’s swept volume b) The pump’s speed c) Operating conditions that may restrict the pump’s ability to self-prime * Several pumps that can deliver the same flow. Must consider factors such as solids handling capabilities, ability to self prime, etc.
  41. 41. Volume Displacement per Revolution Pump Capacity per rev (Gallons) 10mm 0.0066 15mm 0.022 25mm 0.0749 32mm 0.1585 40mm 0.33 50mm 0.705 65mm 1.5 80mm 2.93 100mm 4.835 125mm 8.8
  42. 42. Maximum Flow Rates Pump Continuous Intermittent 10mm 0.45 GPM 0.72 GPM 15mm 1.65 GPM 2.64 GPM 25mm 8 GPM 9.6 GPM 32mm 14.8GPM 19.8GPM 40mm 26.3GPM 35 GPM 50mm 42 GPM 56GPM 65mm 76 GPM 112GPM 80mm 117GPM 175 GPM 100mm 146 GPM 242 GPM 125mm 242 GPM 395 GPM
  43. 43. Discharge Side Considerations • The maximum discharge pressure is 16 bar or 232 PSI • What does discharge pressure consist of? • Absolute Pressure • Hydrostatic Head • Frictional Losses • Impulse Losses (the one most forget) • Tip: When pumping products that tend to settle, such as heavy slurries, some will engineer in an under-sized pipe diameter. Therefore, for long lines, pulsation dampers are generally needed
  44. 44. Discharge considerations HYDROSTATIC HEAD LOSSES Pressure associated with moving a fluid with or against gravity Ps = S.G. x gravity x height FRICTIONAL HEAD LOSSES Different equations for type of flow Based on flow, viscosity, pipe length, pipe ID, pipe type, pipe layout ABSOLUTE PRESSURE Atmospheric 14.7 PSI (or absolute containment pressure)
  45. 45. Suction Lift Considerations • Flooded Suction Preferred • Hose Pumps Can Lift 30’ Water Column • Give Hose Time to Restitute – Consider Pump and hose size – Consider Pump Speed (run slow) – Consider Piping Arrangement
  46. 46. Viscosity Considerations • Newtonian - viscosity unaffected by motion or agitation (Water), i.e. doesn’t change moving through the pump • Non Newtonian - Viscosity affected by motion – Thixotropic: Shear thinning (Yogurt, Mayonnaise) – Dilantant - Shear thickening (Kaolin Clay, Corn flour) • Units are typically measured in centipoise – Common liquid viscosities: • Water (68F) 1 cp • Egg Yolk (40F) 1,600 cps • Honey (65F) 11,000 cps • Honey (100F) 1,400 cps
  47. 47. Viscosity Considerations • Under viscous conditions, hose cannot restitute to its full size, causing a decrease in volumetric efficiency • Flow to the pump is generally key to application • Running at slower speeds allows more time for hose to restitute at a given flow rate • Use larger piping, shorter pipe runs, and few elbows/connectors to keep from restricting flow
  48. 48. Pulsation Effect • When the upper shoe leaves the hose, product will try to flow back into the pump and it collides with product being pushed ahead of the lower shoe. • The causes a hammering effect or pulsation • SOLUTIONS include resizing pipe work or installing flexible hoses or fitting pulsation dampers
  49. 49. IMPULSE LOSSES What Increases Pulsation? Pi = c1* (La * F * n * s.g.) D2 Pi c1 La F n sg D = = = = = = = impulse losses constant actual pipeline length pump capacity pump speed specific gravity diameter of the pipeline
  50. 50. Minimize Impulse Losses • • • • • • • Short Piping Runs Oversize Piping (Where Possible) Minimize Restrictions & Elbows Run Pump at a Slow Speed Use Flexible Lines Use pulsation dampeners where needed Consult factory to review system
  51. 51. General Installation Tips • Pipework should be as short and direct as possible • Piping should be over-sized, especially the suction line • Include a short, removable section next to the pump for easy access (hose changes etc). Preferably this should be a flexible hose • Lines should include valves and a discharge line pressure relief device (closed valve protection). They should also include a product drain down capability
  52. 52. HOSES the soul of Peristaltic Pumps
  53. 53. Hoses – The Soul of a Peristaltic Pump • Hoses are custom produced to very tight specifications – Cannot put a standard reinforced hose into a Peristaltic Pump. Must be specifically made for this duty. – Natural Rubber (NR) – Nitrile Buna Rubber (NBR) – Ethylene Propylene Diene Monomer (EPDM) and – Chlorosulphonatedpolyethylene Monomer (CSM or CSP) or Hypalon ® • Hoses have been developed for increased fatigue resistance – the most likely cause of normal failure • Some hoses interchangeable in other hose pumps – make sure you know which ones!
  54. 54. Not all EPDM Hoses are the same… EPDM Natural Rubber • • • Some made with EPDM liner, Verderflex hoses made with 100% EPDM EPDM is used when chemical attack is the likely cause of hose failure – A solid hose will last longer : there is more chemically resistant rubber – A lined hose allows small quantities of chemicals to leach through the outer cover once the resistant liner is breached A pure EPDM hose has better thermal resistance – The weak point of a liner hose is the bonding between the dissimilar rubbers, which typically melts at 105°C, giving a max continuous working temperature of 80°C. – A pure EPDM hose is good for 115 – 120°C when bonding between homogenous layers of EPDM starts to melt, allowing a higher maximum continuous limit of 100°C
  55. 55. Factors Influencing Hose Life • • • • • Speed Discharge pressure Temperature Chemical compatibility Duty cycle Hose Manufacturing
  56. 56. Cross-sectional views of standard Peristaltic Hoses Competitor Hose Verderflex Hose
  57. 57. Hose Distinctions • Verderflex hoses have a larger number of reinforcement layers than others – During the manufacturing process, rubber is pressed into the reinforcing fibers, trapping the rubber for greater strength – The compressing load (to close the hose) is spread across these reinforcing fibers – The higher the number of fibers, the better the load distribution and reduction of load per fiber – Hence, better fatigue life
  58. 58. Hose Distinctions • Most other hoses’ reinforcement layers are spun into place during manufacturing – The spinning process limits both the number of fibers and the size of reinforcements that can be built into a hose • Verderflex hose does not use a spinning process, so it can use more fibers to equalize the compressive load and this gives the Verderflex hose it’s superior fatigue strength
  59. 59. Extruded/Machined Hoses vs. Vulcanization •Extrusion does not permit close diametrical tolerances to be maintained •Extruded hoses must be ground to meet these tolerances, typically 2mm to 3mm from the surface •Vulcanized hoses are hand made which achieve tolerances w/o grinding or surface abrasion Surface Roughness: •“Ribbed” exterior of Verderflex hoses actually aides in lubricant distribution to top of hose, allowing for cooler running •Radial load more on machined hoses than on Verderflex Hoses
  60. 60. Verderflex VF-Series Close-Coupled Hose Pumps
  61. 61. Anatomy of a Hose Pump Pressing Shoe Discharge/ Outlet Port Reinforced Hose Cast Iron Housing & Rotor Suction / Inlet Port
  62. 62. Rotor and Pressing Shoe Assembly • Aluminium Rotor Shoe • Stainless Steel Shims: – These allow hose compressing force to match discharge pressure • Cast Iron Rotor with Taper Lock Bushing • No Shoes on VF10 or VF15 or Dura – These have low or high pressure rotors only
  63. 63. Port Flange Assembly – VF • Shows the sealing ring, the port flange and the hose insert • Sealing ring is supplied as part of port flange assembly or as a flange sealing kit for service use
  64. 64. 4 Build Positions
  65. 65. Hose Pump Types • There are two styles of hose pumps – • Close Coupled – The pump’s rotor is mounted directly onto the gearbox’s shaft and the drive is bolted directly onto the pump’s drive flange • Long Coupled – The pump’s rotor is mounted onto the drive shaft of a bearing assembly. The stand alone gear motor unit is connected to the pump by a flexible coupling
  66. 66. Advantages of the VF-Series Simplicity…. Due to the simplicity and flexibility of a close-coupled configuration, only 3 parts needed to change a rotor (Rotor, shaft, & taper-lock bushing) Multiple pieces, special tools, bearings, presses, and spline alignments required with other hose pumps VF Series vs Competitor
  67. 67. Verderflex Fail Safe Hose Clamping Assembly Safety & Reliability • The insert sits inside the hose • The sealing ring fits over the hose & as the flange is tightened into the casing, the machined taper in casing forces the sealing ring to tighten onto the hose securing the insert in place • The assembly will withstand pressures in excess of 30 bar / 435 PSI • The hose to be pushed onto the discharge port & the pump action tries to pull the hose off the suction port – this is why the suction side sealing rings always “bite” harder into the hose
  68. 68. Safety & Reliability • • The Verderflex hose connection safely and securely contains the hose entirely within the pump casing. Some competitors have an exposed hose connection. • Chemicals have a leak path that can lead to workplace contamination. • These pumps also have exposed band clamps that can rust and corrode, becoming difficult to remove.
