(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!

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

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.

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.

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

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)

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

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

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

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

•

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

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

HOSES

the soul of Peristaltic Pumps

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!

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

Hose Manufacturing

Cross-sectional views of
standard Peristaltic Hoses

Competitor Hose

Verderflex Hose

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

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

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

• Cast Iron Rotor with
Taper Lock Bushing
• No Shoes on VF10 or
VF15 or Dura
–

These have low or high
pressure rotors only

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

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

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

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

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.

Dependability / Longevity
•

•

Stronger more robust rotor design
prevents cracking in overload /
stalled conditions
Higher strength
Aluminum shoes hold up
to better to higher loads
and withstand harsher
conditions than Epoxy
shoes, which tend to
crack under high stress

Summary of Verderflex VF Series
• Widest range of peristaltic hose pumps in the world,
from 5mm to 125mm
• Robust industrial pump designed to withstand the
harshest process conditions
• Simple and safe clamping system contains all product
within the casing
