5. 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

6. 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)

7. 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%

8. 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)

9. 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”

10. 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

11. 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%

12. 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

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

19. Pumping - Submerged Structures
Key attributes
•The ability to pump
the pebbles in the mix

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)

21. 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

(abrasive) activated carbon
slurry as part of an exhaust
gas dioxin removal system at
a waste incineration plant

is 15-20% by volume.
Environmental regulators
insist if the pumps don’t run
then the plant doesn’t run
either!

46. 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

( the pump is only used once a year)
- only the hose is exposed to cleaning
solution
- the pump self primes and
- can run dry

53. Summary
 Verderflex pumps can be used in many
applications in many industries
 Look for one of the key signs for an
existing pump problem as the VF is often
used to solve existing problems
