ALBIN vs. BREDEL
I ricambi ALBIN sono compatibili con la gamma Bredel SP
Gamma di pompe più ampia:
ALH, miglior rapporto velocità/prezzo o vita del tubo/prezzo.
Sostituzione pattini:
ALH, dalla finestra senza svuotare il lubrificante
Non possibile con Bredel
Gamma SP: finestra troppo piccola, bisogna rimuovere il
coperchio
Gamma SP(X): livello del lubrificante superiore alla finestra
Faciule rimozione del rotore:
ALH, sistema Vécobloc, manutenzione molto facile
Gamma SP: accoppiamento a pressione
Gamma SP(X): assemblaggio complicato, il cliente deve
essere molto esperto per farlo autonomamente
Materiali coperchio e rotore:
ALH in ghisa sferoidale, migliore resistenza meccanica.
Gamma Bredel in ghisa grigia, possibile rottura dei rotori
Cuscinetto della pompe:
ALH, nessun cuscinetto
Gamma SP: difficile sostituire i cuscinetti sul retro della pompa.
Gamma SP(X): cuscinetti all’interno del rotore in contatto con il liquido pompato
Coperchio pompa
ALH con 30% in meno di bulloni
I materiali dei tubi
I tubi sono disponibili in 5 materiali diversi da
scegliere in funzione del liquido da pompare:
• NR (natural rubber) : marchio bianco
• NBR (Buna): marchio giallo
• NBR food (Buna): marchio giallo e bianco
• EPDM: marchio rosso
• HY Hypalon: marchio blu
Cleaning of the hose
The hose is cleaned in order to avoid:
¾ Hardening of the fluid on the inner wall of the hose
¾ Mixing various pumped fluids
It consists in:
¾ Water cleaning
¾ Cleaning with an agent
(compatible with the hose material)
¾ Cleaning with sponge balls

Corretto numero di spessori
La distanza ottimale tra i pattini e il corpo pompa si ottiene con
l’utilizzo di spessori in numero variabile in funzione della
pressione di lavoro. (pompe ALH25 - ALH125)

La pressione di lavoro deve essere specificata negli ordini di
acquisto: ogni costruttore fornisce le pompe con gli spessori
già montati!
Corretto numero di spessori
Per comprimere un tubo ALH80 in NR bisogna applicare la
seguente pressione:
5 bar di lavoro, « nessun spessore » ==> 2 tons
Se usi 2 spessori,==> 4 tons
Durante test a 15 bar con acqua ==> 8 tons
123 mm
38,6 mm
37,6 mm
37,6 mm
Un’ottima compressione del tubo si traduce in una perfetta distanza tra pattini
e corpo pompa
Se usi un tubo ALBIN in una pompa BREDEL (specialmente tipo SPX), devi
ridurre il numero di spessori come da tabelle Albin.
Bredel suggerisce anche 14 spessori sulla gamma SP, mentre ALBIN
consiglia un massimo di 5!!!
Perchè i tubi Albin hanno
durata maggiore?
Tre ragioni tecniche:
¾ Miglior qualità della gomma
¾ Miglior strategia con gli spessori
¾ Miglior selezione dei materiali dei tubi
Better quality rubber
Albin Pump SAS has 31 years on hand experience and decided to use the
best available quality rubber to have the best abrasion resistance.
Our main competitors rectify their hose to get a 0,3 mm tolerance on their wall
thickness. For this reason they have to use a rubber with a low abrasion
resistance. Albin Pump Hoses are extruded with a 0,5 mm tolerance on their
wall thickness.
Albin Pump’s Natural rubber hose uses the
same quality rubber for the entire thickness
of the hose while the competition use
different types of rubber increasing the
chance of delaminating between the
reinforced lays reducing their life.
With an un-machined hose , the lubricant has a better
grip on the hose, causing less friction and heat build up
between the shoe and the hose, resulting in a better
hose life.
Miglior strategia nella
scelta degli spessori
La vita del tubo è
proporzionale a pressione e
velocità di lavoro, numero di
spessori.
Dopo numerosi test, Albin ha
deciso di ridurre drasticamente
il numero di spessori utilizzati.
Alcuni concorrenti arrivano fino
a 14 in alcuni casi!!!

Better rubber quality selection
Albin Pump SAS with their on hand experience don’t follow the common chemical
compatibility rubber charts.
For hose pumps, the mechanical resistance is a lot more important than the chemical
résistance for the hose life.
Hose life test depending of material:
This test has been made by a rubber manufacturer on all hose
pump manufacturer, the result was very similar.
On test on water (No chemical attack) ( 60 Rpm, 10Bar):
NR hose has a life span:
Double than EPDM
Triple than NBR
Most of our competitors are blindly using the compatibility table
from the rubber manufacturer.
By using Natural Rubber hose in place of EPDM, on most of acid
applications, the life time is largely increased
Hose destruction’s areas
Normal end of life
Over shimming
Chemical attack
Under shimming
Over shimming
Over shimming
• This failure occurs in the cheek of the
hose as the hose starts to re-vulcanise
• Rubber is built up under the shoe,
leading to severe internal friction and a
heat build up, resulting in revulcanisation
• The failure will occur over the rotor
shoe’s full contact path
Chemical problems
• The inner rubber has softened due to
chemical action
• Parts of the rubber breakaway when they
are pulled and may stick together
Under shimming or
Pulsation damage
• Damage occurs where the shoe leaves
the hose
• Failure is due to backflow of an
abrasive product from severe pulsation
• Remedy - remove the source of
pulsation not to increase number of
shims
• Shows as very high discharge side
impulse loss
Hose life solutions
Problem 1: Poor Quality Parts
Some people purchase poor quality hose, because it's cheaper. Their
experience with time will show that hose fails prematurely and that they
spend more money on buying extra lubricant and then have the additional
cost and inconvenience of downtime
ALBIN Solutions
Hose
It is essential that you purchase hose and lubricant from a credible source. Our
hose has taken many years to perfect and is typically of tri-laminar construction,
providing an excellent life expectancy.
Not just experience, but sophisticated manufacturing technology also means that
a World-class hose can be created each time, every time.
For the production of our hose we use a fully automated facility that ensures that
dimensions are held to the tightest tolerances.
Lubricant
As with hose, our lubricant has been designed to work perfectly
with the varying requirements within a hose pump. The range of
requirements within a pump, means that the lubricant needs to
support not only hose cooling, but also have an inbuilt guard
against freezing during winter time.
Our hose pump lubricant fulfils all these requirements
Hose life solutions
Problem 2: Pump Speed
Hose for peristaltic pumps has a finite and often predictable life if all factors are
consistent within a process and it will provide a number of compressions and returns
in its operation before failure.
Pump speed has a direct effect on hose life, to the point where we could say as a
guide, if you double your pump speed you will half your hose life. Conversely if you
half your pump speed you will approximately double your hose life.
This simple guide has helped hundreds of pump installations to improve their hose life
dramatically.
ALBIN Solution
As you can see the pump speed has a dramatic impact on the life of a
hose for peristaltic pump. This being the case it is essential that when
you are considering purchase you contact us to discuss your
application in detail to ensure the correct pump is selected from the
start.
More often than not it is wiser to purchase a larger pump and run it
slower, than to squeeze the duty onto a smaller pump running fast
and then suffer the cost of more frequent hose replacement.
If you have already purchased a pump and do not want to upgrade to
a bigger pump, please give us a call and we will talk through your
application and make recommendations.

Problem 3: Incorrect Hose Materials
If your pump hose is failing regularly, it would be appropriate for us to check the
compatibility of the hose material with what you are pumping through it.
ALBIN Solution
Our peristaltic pump hose comes in a wide range of materials.
When we select a hose for peristaltic pumping, we consider many
factors including the liquid that you are pumping, temperature involved
and general duty expectations.
In order to extend your current hose life, we would review the duty
application and ensure that the optimum material was employed.
Often we have found for example that natural rubber hose or natural
rubber tubing has been selected for an application because of its
excellent physical properties, only then to have the application changed
to a more acidic product causing the rubber to rot away prematurely.
If you have a pump running whose hose life has reduced with time and
is no longer acceptable, let us come and take a look for you
Hose life solutions
Problem 4: Suction Lift
If your application has a suction lift, many forces are placed on the pump hose that
can lead to premature failure.
ALBIN Solution
A major improvement can be seen in hose life, through the introduction of a correctly
sized dampening device.
Give us a call and we would be happy to advise.
Problem 5: High Pressure Discharge
For similar reasons to point 4, large pressure on the discharge can
create considerable strain on the hose.
ALBIN Solution
We are one of the few companies who provide special long life
hose for these types of application. In addition, we can provide a
discharge pulsation dampener to reduce pressure shock to the
hose and once again increase hose life
Problem 6: High Temperature Application
If you are pumping at a high temperature this can lead to early hose
failure
ALBIN Solution
We would be happy to review your installation to consider ways that
temperature can be reduced.
