Digital Chemical Dosing System
nnnnProvides High Accuracy,
nnnnExcellent Repeatability For Hatcheries
nnnnGregg E. Johnson, Thermo Fisher Scientific, Fluid Handling, Barrington, IL, USA.
nnnnAppropriate treatments are neces-
nnnnsary to reduce the dissemination and
nnnnamplification of infectious diseases
nnnnand pathogens that can lead to egg,
nnnnfry, and fingerling mortality. But
nnnnoverdosing drugs or chemicals such
nnnnas formaldehyde solutions can lead to
nnnnabove normal treatment losses while
nnnnunderdosing will provide inadequate
nnnntreatment. Maintaining precise dosing
nnnnaccuracy often presents major chal-
nnnnlenges for hatcheries - especially those
nnnnoperating older generation peristaltic
nnnnpumps with insufficient calibration
nnnncapabilities and poor repeatability.
nnnnDosing precision
nnnnUnlike many pump designs,
nnnnThermo Scientific Masterflex®
nnnnpumps easily maintain a precise,
nnnnconstant dosage rate with excellent
nnnnrepeatability - providing accuracies
nnnnof ± 0.5% or better. With adjustable
nnnn650:1 resolution, bi-directional
nnnnflow and self-priming capabilities,
nnnnMasterflex systems provide for
nnnnsmooth, seamless operation plus
nnnnthe dosing precision that is crucial
nnnnfor the integrity of flush treatments.
nnnnMany Masterflex pump heads offer
nnnnfixed occlusion to ensure optimal
nnnnperformance without the need for user
nnnnadjustments.
nnnnA versatile tool
nnnnHigh accuracy and repeatability
nnnncombined with low maintenance have
nnnnmade the Masterflex pump a versatile
nnnnand invaluable piece of equipment
nnnnfor today's modern hatcheries.
nnnnDesigned for fast, simple field set-up
nnnnand calibration, Masterflex offers
nnnnmaintenance-free brushless motor
nnnndrives and roller and ball bearing
nnnnpump head construction that provides
nnnnfor a robust, powerful pump in a small
nnnnpackage - ideal for portable use for
nnnnmultiple applications. Many models
nnnninclude digital drives with simple
nnnnpush-button calibration for optimum,
nnnnrepeatable performance.
nnnnInnovative, cost-effective digital
nnnndosing systems
nnnnThe risks to hatchery operations from
nnnnunderdosing or overdosing chemical
nnnntreatments are too high today to rely
nnnnon old dosing technology. Hatcheries
nnnnusing older generation peristaltic
nnnnpumping systems that provide only
nnnna single turn (10:1) potentiometer,
nnnnor no speed adjustment, and poor
nnnnfield calibration capabilities not only
nnnncreate extra work for technicians,
nnnnUser-friendly Masterflex systems are an
nnnninvaluable piece of equipmentfortoday's
nnnnmodern hatcheries
nnnnit can present a serious potential
nnnnrisk when making critical chemical
nnnnadditions.
nnnnMasterflex pumps, on the other
nnnnhand, are innovative, cost-effective
nnnndigital chemical dosing systems,
nnnnoptimally designed to provide
nnnnreliable, precise, and repeatable
nnnnchemical treatments for virtually all
nnnnhatchery applications. Rather than
nnnnrelying on a 10:1 speed adjustment
nnnnthat provides ±10 % accuracy,
nnnnMasterflex systems provide a
nnnnmanually adjustable 650:1 resolution
nnnnfor up to 20 times the accuracy, and a
nnnnrepeatability rate of 99.5 percent.
nnnnWhether it's bath, dip or flush
nnnnchemical treatments for hatching
nnnntrays, hatchery troughs, raceways, or
nnnnponds, Masterflex peristaltic systems
nnnnhelp maximize productivity and
nnnnprofitability through precision dosing.
nnnnField calibrations and set-up are easy
nnnnand precise. Plus, hatcheries can dose
nnnnup to eight runways simultaneously
nnnnrising a single Masterflex drive
nnnnmounted with eight Masterflex pump
nnnnheads, reducing manpower and
nnnnoperational costs even further.
