1. ABAQUE
Hose Pumps

2. HOW IT WORKS
The peristaltic pump principal was found by Mr. HORTAUS in France in 1925.
A pulsative flow is generated by compression
of an elastomeric hose against a pump casing
with two opposed shoes assembled
on a rotating wheel.
Friction between shoes and
hose are reduced by using a
lubricant which also acts as a coolant.

3. HOW IT WORKS
The pumped fluid is only in contact with the inner wall of the hose and insert.
The pump has no mechanical seal.
The rotation action moves the product through the hose at a constant rate of displacement without slip
Particles trapped at the passage of a shoe penetrate the hose wall and are ejected in the fluid without damage to the inner surface of the hose.

11. LEAK DETECTOR
To avoid spillage of product after a hose failure, a capacitive detection sensor can be installed on the level pipe.

12. VACUUM KITS
Flowrate is reduced when pumping high viscous products or having a high suction lift. To ensure pump’s performance Abaque pumps can be equipped with 2 different vacuum kits according to customer’s process.
Air Suction Flange Kit Fitted
on the Inlet of the Pump
Casing depressurization equals inlet pressure
Air is mixed with fluid
Not to be used if rotation in both directions, or if inlet pressure is positive
Only available for AB65 and larger
Air Ejector Kit for Pump Turning in Both Directions
Venturi ejector
Up to 90 % vacuum
5 to 6 bars air pressure

18. HOSE LIFE Depends on : Pressure Rotation Speed Hose Material
Liquid Temperature
Service
Correct External OD Machining
Correct Shimming

19. Critical Area out of Shoe Passage
PRESSURE
There are 3 stress factors for hose life :
Compression
Pulsative pressure
Buckling
Critical Area out of Shoe Passage

20. ROTATION SPEED  Shoe Speed Limitations
When Pump Rotation Speed Increases:
Speed of Shoe on Hose Increases
Higher friction on hose
Higher hose temperature
Faster destruction (detachment) of layers
Hose stretches and becomes longer
 Shoe Speed Limitations V1
V2 > V1
Shoe - Hose

21. HOSE MATERIALS
Reinforcement layers are assembled with an extremely adhesive rubber and are spaced so that direct contact between them is impossible during the hose deformation.
1st Choice (if possible) : NR
 General purpose hose
 Particularly good for abrasive fluids
2nd Choice (if possible): EPDM
 Acids & corrosive fluids
3rd Choice: NBR
 Oily and fatty fluids

22. LIQUID TEMPERATURE Maximum Liquid Temperature: NR: 70°C NBR: 70°C
EPDM: 80°C
Temperature impacts hose life directly and requires limited speed :
Example with AB65 :For same lifetime, at 80°C  42 % of 50°C speed

23. SERVICE pump is running no more than than 2 hours
Maximum speed allowed depends on pump’s service
Intermittent Duty
pump is running no more than than 2 hours
AND stopped at least 1 hour
Continuous Duty
pump is running more than 2 hours
OR stopped less than 1 hour

24. SHIMMING Hose Not Enough Compressed Hose Too Much Compressed
Correct Shimming guarantees maximum hose life.
Hose Not Enough Compressed
 Internal Recirculation of Liquid
 Hose life reduced due to splitting
Hose Too Much Compressed
 Buckling and unnecessary Brake Power
 Lower hose life

25. CORRECT SHIMMING
Optimal compression of the hose means optimal distance between shoes and casing
This distance depends on differential pressure & rotation speed a
bar (psi)
rpm
mm (inch)
P < 5 (72.5)
5 < N < 40
25.6 (1.008”) < a < 26.1 (1.028”)
40 < N < 120
26.1 (1.028”) < a < 26.6 (1.047”)
120 < N < 160
26.6 (1.047”) < a < 27.1 (1.067”)
This optimal distance between the shoes and the casing is obtained by adding shims between the shoes and the wheel (AB25 to AB100)

26. CORRECT EXTERNAL DIAMETER MACHINING
All Abaque hoses are machined.
Constant thickness along entire length:
- Optimum Compression
- Lower Power Consumption
Repetitive hose dimensions.

27. PUMPING SEDIMENTARY LIQUIDS
Inlet
Inlet port must be positioned on the top to avoid sediment abrasion effect
Outlet
A back wash may be required to avoid product build up on the hose inner wall
Avoid bends and curves on discharge line

28. TYPICAL APPLICATIONS Water and Wastewater Treatment
lime slurry, polymer feed and transfer, carbon slurry, alum, sodium hydroxide and sodium hypochlorite dosing, sludge's and slurries

29. FILTER PRESS APPLICATION EXAMPLE
Due to high pressure and volumetric capabilities,
the Abaque is perfectly adaptable to filter press applications.
Filter Press Hose Pump curve 2 4 6 8 10 12 14 16 5 15 20 25 30 35 40
Pump Speed in RPM
Discharge Pressure in Bar
Initially, the filter press is empty and the pump delivers high volumes at low discharge pressure. As the press gradually fills and as the pressure increase, the speed of the pump is reduced to reduce the amount of product being fed to the press.
