DISPENSING PERFECTION

World leader in dispensing pumps from lab to production

Peristaltic pumping:
the perfect dispensing solution
Watson-Marlow Bredel leads the world in
manufacturing high accuracy peristaltic
dispensing pumps and tubing, representing
the best combination of speed, accuracy,
ease-of-use, and versatility of any dispensing
device. Our peristaltic design is perfect for
dispensing delicate, viscous, corrosive orabrasive fluids in research and production
processes around the globe.
With peristaltic pumping, only the tubing is incontact with the fluid; there are no moving
components in the fluid path which may
contaminate the product.
In a wide range of automated and manual
dispensing applications, our customers rely on
the accuracy, repeatability, efficiency, andcontamination-free operation that only a
Watson-Marlow Bredel peristaltic dispensing
pump can deliver including:• Fully automated aseptic fill/finish inpharmaceutical/biopharmaceutical
drug manufacturing• Benchtop media or reagent preparation inlaboratory suites – filling or inoculatingbottles, vials, Petri dishes and media bags

• High speed automated filling of blister
packs and containers for contact lenses
and cosmetics• Dispensing of fragrances, extracts, andother additives• Addition of colors, dyes, flavors, vitamins,
and other ingredients in food production• The fluid touches only the inside of theperistaltic tube which can be changed inseconds - no check valves, gears, seals or
diaphragms to wear, clean or replace• Software-controlled precision, with no cams,
diaphragms and valves to adjust by trial anderror and clean or replace when they clog

• Interface is through logical user-friendly
Unmatched features

key-presses with simple, on-screen readouts

Watson-Marlow Bredel peristaltic dispensers
offer many advantages over other types ofdispensing methods such as pistons, gear

Savings on cleaning

The technology
behindperfect
dispensing

The company reports
substantial savings
resulting from reduced
downtime for cleaning
between batches of fluids,
as well as high-accuracy
performance and theelimination of waste at
set-up time.

A Watson-Marlow Bredel
dispenser is designed to give theperfect dose every time without
splashing, drips, or other inaccuracies.

Motor runningat constant speed

Deceleration periodof motor

Programmable ramping aids
accuracy and protects yourproduct by allowing filling tostart and stop with nosplashing or foaming. The
pump speeds up at the startof a dose and slows down at
its end, allowing the highest
speed to be used for the mainpart of the dose.

Reliability and easycleaning are importantfeatures of Watson-Marlow
Bredel peristaltic pumping,according to Dales
Pharmaceuticals, who use
a 500 series dispensing
pump to package a wide
range of pharmaceuticalpreparations. Before taking
delivery of their new pump,
Dales used a pneumatic
machine to dispense
volumes varying from 10ml
to 100ml, of 10 major fluids.

Drip Control
Programmable anti-drip control avoids end-of-dose dripping with amomentary direction reverse at the end of each dose.

Low Pulsation
Peristaltic pumps are less pulsatile than most positive displacement
pumps but still have some pulsation. Our 520L and 620L pumpheads
eliminate pulsation. The inlet flow is split between twin tubes compressedby offset tracks, producing two sets of pulses out of phase with eachother. When the channels are merged at the discharge, the pulse of one iscancelled by the flow of the other – providing a smooth outlet flow.

Tubing Power100%

Our own Pumpsil-D
platinum-cured silicone
tubing is formulated
specifically for highaccuracy dispensing. Its
resistance to fatigue stressand superior flex memory
doubles its dispensing
accuracy over othersilicone, ensuring fewer
calibrations over time.

Like all Watson-Marlow
Bredel silicone tubing,Pumpsil-D is postcured
during manufacturing to
remove residual linear andcyclic siloxanes which canleach out of otherplatinum-cured tubing.
And with Pumpsil-D
there’s no concern
for contamination from2,4 DCBA which canleach from peroxidecured silicone.

Unrivaled flow range
Each dispensing drive can accept a variety of single
channel or multichannel pumpheads to meet yourneeds. And each pumphead can accept a number oftubing bore sizes in continuous tubing or elements,
allowing a single pump to have a flow range of overone million to one.
Maintenance-free brushless DC drive
Our pump drives feature brushless DC motors andhigh-performance gearboxes for speed accuracy to
0.1%. No brushes means no carbon-dustcontamination and no maintenance. Drives are 24/7duty rated, with full software protection. Turndown
ratios extend to 3,500:1.
Clean and rugged construction
520Di and 620Di dispensers have a tough, corrosion
resistant, crevice-free case for every environment.
Choose NEMA 2/IP31 pumps for dry environments.
Use the NEMA 4X/IP66 for wet areas subject to highpressure washdown.
User-friendly controllability
Control the pump through the waterproof membrane
keypad with easy read, easy-to-use tactile keys big
enough for gloved hand operation.

Secure user-defined programming
Store 50 dispensing programs for immediate use:complete with batch size, dose size, flow speed,
dosing interval, ramp and drip settings. Enter andrecall all parameters from the keypad using clear
input prompts. Protect from inadvertent changes
using security PINs.
Batch records
Connect the pump to a PC for display, storage,
and printing of batch records complete with alldispensing parameters including dates, times, andoperator identification.

LaserTraceability™
Every piece of Pumpsil-D tubing
is permanently laser-etched,
end-to-end, with part number,
lot number and use-by date.
Pumpsil-D offers full traceability
for validated processes.

520Di – The ultimate pump for high-speed,

Accuracy boosts
production

The most sophisticateddispensing pump available“A self-funding investment a finance director's dream”
is how Colin Paine, MD of
Casp Products, describes
the introduction of WatsonMarlow Bredel peristaltic
pumps into his production
process. Casp makebacteria-testing kits forcompanies maintaining
water cooling towers
throughout the world.
Testing accuracy is
destroyed if quantities ofviscous nutrient media areimprecise. Other pumps
had failed to yield therequired precision becauseof variations in ambient
temperature.
A Watson-Marlow 500
series pump with twin 313
pumpheads dispenses
more than 5,000 3.5ml
shots per shift, at less than
1 second each. Since thepump was installed,
improved dosing accuracy
has increased production
yield by 5-8%.

The 520Di offers easy calibration by weightor volume, with doses triggered by interval,
keypad, remote signal or additionalfootswitch, handswitch or proximity switch.

• Output batch records for cGMP
requirements are automatic• RS232 and RS485 are available on
NEMA 2/IP31 and NEMA 4X/IP66 models
respectively, plus control by logic I/O
