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

Principle of Operation

•Slow speed rotor with 2-sliding shoes alternately compress and relax a rigid but flexible hose providing accurate and wear resistant operation

Application Keywords

• 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)

Application Keywords II• 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%

Application Keywords III

• 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)

Dosing - The Key Advantages

• Abrasion resistance

• Suitable for handling shear sensitive products (floc)

• Has no internal backflow giving accurate dosing- no slip

- repeatability ± 1%- metering ± 5%

• Able to pump liquids containing up to 80% inorganic solids and can also pump air or products that “gas”

Dosing Formats

• There are 2 standard dosing styles

• Fixed speed: constant dosing rate

• Inverter control -– variable dosing over a range by manual or

feedback control – 4-20 mA loop or SCADA via inverter– Flow-pacing

Linear Speed/Flow Characteristic

•This is the key parameter for variable speed dosing applications - to increase the flow by 10%, increase the pump speed by 10%

Polymer & Coagulant Dosing

• Many polymers & coagulants are highly shear sensitive

• PC and other pumps will reduce particle size by around 50 to 70%, increasing coagulation time and polymer usage and reducing throughputs

• The gentle pumping action of peristaltic pumps maintain particle size and maintain designed performance

•Breweries– Diatomaceous earth– Kiezelguhr– Brine solutions (salt

water)– Yeast after storage

(Gelager)– Yeast after

fermentation– Fresh yeast dosing– Additives for taste,

extending shelf live– Polyvinyl Pirolidoom

PVPP Filter

•Wineries– Diatomaceous

earth with yeast– Wine dust

•Flavoring– Adding flavors and

colors… other additives.

Breweries and Wineries

Brewing - Dosing Yeast• Why use Verderflex ?

• Yeast is very abrasive• Yeast is shear sensitive• Pump can run dry• Pump self primes

• Traditional solution was a• Rotary lobe pump• High stator wear• Cost of ownership• Costly downtime

Customers include BASS / INTERBREW (HEINEKEN), GUINESS and CARLSBERG

Diatomaceous Earth Filter Presses•Yeast is a challenging product to pump

Blue Verderflex pumps are supplied by Seit Schenk in Waldstetten, Germany as part of their diatomaceous earth or Kieselguhr Brewery filter press systems

•These replace Screw fed Centrifugal pumps due to excessive wear and yeast damage

Bentonite & Cement slurries Cement & Sand Slurries China Clays (Kaolin) Foamed & Re-enforced Mortars Fly Ash Gypsum Plaster Pigments Water Based Paints

Building & Ceramic Industries

Pumping Building Mortars

•Verderflex pumps are ideal for pumping building mortars due to their abilities to pump a slurry with a high solid content, provide consistent dosing and reduced maintenance costs

•Several pumps use hydraulic motors that are connected to mobile power packs to give a mobile pumping solution

Pumping - Submerged Structures

Key attributes

•The ability to pump the pebbles in the mix

•The ability to pump a high solid content

•The abrasive nature of the product

•NR hoses used

Dosing Roof Tile Pigments

•Many Verderflex pumps are used to dose pigments in roof tile manufacturing, offering flexibility in performance as the pump duty can be changed by adding or removing shims

•Customers include Lafarge (Redland Roofing (UK)), Marley group and Braas & Co (Germany)

Pumping Clay in the Ceramic Industry

•Verderflex pumps can be used in the ,manufacture of many ceramic items such as roofing and bathroom tiles and other clay based products

•Typically, they replace AOD pumps which have high spares costs due to the abrasive nature of clay and clay slurries

• Hydrochloric acid (<38%)• Sodium hydroxide

(caustic)• Potassium hydroxide• Water based paints• Latex• Ammonia• Phosphate slurry• Sulphuric acid

Chemicals, Soap & Detergents

• Adhesives• Dosing perfume for soap

production• Toothpaste• Shampoo• Liquid soap• Abrasive cleansing products • Dyes• Perfumes• Micro Capsules

Chemical Filter Presses•VF50 feeding Aluminium Oxide to a filter press

•In this application, the back pressure and gearbox combination resulted in the pump reversing while maintaining 15 bar – fitting a drive brake onto the gear motor eliminated this problem

Steel Treatment Feeds

•SADEF in Belgium use a number of VF15s and VF32 to dose treatment chemicals including HCl as part automotive steelwork preparation for Mercedes, Volvo and DAF

Transfer Pumping

•Customer is a Korean plastic components sub-contractor for Daewoo and Kia cars

•VF50 unloads 1000 litre tanks of Polypropylene Glycol

Transferring Waste Potato Peelings

• Customer : Golden Wonder, GB

• Problems were -Air in product

Variable viscosityProduct slip

• Replaced Tuthill rotary lobe pump –Unable to suck the sludge out of collecting bin

Pumps clogged up as RLs do not have 100% positive displacement capability I.e. there was slip

• Benefits - Less downtime, reduced maintenance cost

Potato Peel 2

•The hose compresses 100%, so there is no product slip or air pocket created in pump

•Peelings are also abrasive - no contact parts to wear : only the hose which is abrasion resistant

Packing Pet food•Customer – CERVO, Holland

Dosing Activated Carbon into Smoke Stacks2 x VF32 pumps dose (abrasive) activated carbon slurry as part of an exhaust gas dioxin removal system at a waste incineration plant

Typical carbon concentration is 15-20% by volume.

Environmental regulators insist if the pumps don’t run then the plant doesn’t run either!

Bacterial Dosing in Soil Remediation

10 Verderflex pumps are used to dose live bacteria for toxic soil remediation in Germany

The bacteria is highly shear sensitive and the gentle pumping action maintains a high live content to maximise treatment effectiveness

• Blood for re-use in pharmaceutical industry

•Verderflex was chosen because it is a –

•Low shear pump

•Provides predictable dosing of a highly viscous product

Mobile Pumping !

•Self contained sewage sludge/lagoon dewatering system: a trailer-mounted VF65 with pulsation dampener

Space Age ?

• A Verderflex pumps cleaning liquid for the world’s most powerful telescope on earth at the European space Observatory in Chile

• The pump was chosen because - it is self-priming- has no seals

( the pump is only used once a year)- only the hose is exposed to cleaning

solution - the pump self primes and- can run dry

Summary Verderflex pumps can be used in many

applications in many industries
