Description
3 | DESCRIPTION
3.1 - IDENTIFICATION OF THE PUMP
ALBIN PUMPS are identiable by the pump plate located on the frame. The plate includes the pump type and serial number of the
pump. This serial number leads to all information concerning building materials, nature of the hose, characteristics of the gearbox
and characteristics of the motor. The gearbox and motor have their own descriptive plate that states the reduction ratio, power,
and electrical voltage.
3.2 - OPERATION PRINCIPLE
PHASE 3
As soon as, at the discharge side, the shoe is detached
from the hose, the other shoe diametrically opposite is
already in compression thus avoiding an internal product
leakage. The product is then successively sucked and
pushed due to the wheel rotation.
PHASE 2
The pumped liquid has now entered the hose. The
second shoe will compress the hose and push the liquid
towards the pump outlet.
PHASE 1
The pump hose is compressed successively by two
pressing shoes assembled on a rotating wheel. The rst
shoe, by pressing the walls of the hose, will create a
vacuum and attract the pumped liquid into the hose.

4 | INSTALLATION
4.1 - UNPACKING AND CONTROL
During the receipt of the pump, please follow the instructions printed on the packing. Make a visual inspection to insure that no
damage occurred during shipment. If this is the case, please contact your ALBIN PUMP distributor as soon as possible.
4.2 - CONDITIONS OF USE
ALH pumps can work in atmospheres where the temperature is situated between -20°C (-4°F) and 45°C (113°F). Pumps are
coated with a 150µ paint which will protect them against certain aggressive environments. They are designed for indoor and
outdoor setup.
4.3 - SET UP
Before installing the pump, check the following points:
- The pump is delivered with a frame provided with four anchoring holes. It must be xed on a solid base with a slope which
does not exceed 5mm for 1m and must be rmly fastened to this one.
- Require enough space around the pump to carry out maintenance. If such was not possible, consider the moving of the pump
to a space provided for this purpose.
- Make sure that the room is adequately ventilated to relieve the heat generated by the pump. Leave a space behind the motor
ventilator hood so as not to obstruct air intake.
4.4 - PIPING
Suction line piping:
- The internal diameter of the piping must be equal to or greater than that of the pump hose,.
- It must be the shortest and most direct possible to avoid suction loss.
- Suction pressures at higher operating pressures may cause the pump to rotate when the pump is disengaged. Above 1 bar,
consider adding a suction line valve to prevent this occurrence.
- Limit the presence of bends and make sure that they are as large as possible.
- Make sure that piping can support the service pressure of the pump.
Discharge line piping:
-The internal diameter of piping must be equal to or greater than to that of the pump hose, see §3.4.
- It must be the shortest and most direct possible to avoid discharge pressure loss.
- Limit the presence of bends and make sure that they are as large as possible.
- Provide a space for a pulsation dampener (see picture below).
- If there is a valve on the discharge line, install a pressure relief valve or an over pressure protection gauge to avoid any
possible damage to the pump and to the installation.
- It is recommended to install a exible line to help absorb pulsation.
During the pump ground study, provide enough space for the hose change as well as the possible installation of a pulsation
dampener. Distance (L) is the required length for hose removal.

6.3.2 - PUMP CASING CLEANING
This operation is necessary when a hose has burst and when the product has contaminated the inside of the pump
casing. Perform these steps with caution. If hazardous chemicals were being pumped, use caution when removing the
lubricant.
1 - Unfasten cover screws by leaving two screws partly fastened to the casing. Slightly withdraw the cover from the
casing and x a shackle in one of the cover’s highest fastening holes (see picture below). Pumps ALH80, ALH100 and
ALH125 are equipped with a lifting ring. Install a lift equipment in this shackle and slightly raise the cover. Unfasten the
remaining screws and withdraw the cover. For cover weight please refer §9.12
2 - Check the state of the cover seal (REF 10) §6.4.1 and replace if necessary.
3 - Check the state of wear of the pressing shoes (REF 5) and replace them if necessary, see §6.4 Replacement of spare
parts.
CAUTION! Worn shoes can contribute to improper compression and premature wearing of the
hose.
4 - In the case of a hose burst, it is possible that the shaft seal (REF 26) §6.4.2 as well as the seal ring (REF 27)
§6.4.2 have been notably damaged when pumping an abrasive liquid. Relate to §6.4 if a replacement of these parts is
necessary.
5 - Wash the casing with clear water and withdraw any residues.
6 - Dry the pump casing entirely.
7 - Replace the cover seal in its groove.
8 - Reassemble the pump cover.
6.3.3 - REASSEMBLY OF THE HOSE

3 - Insert the hose by the outlet port (REF 6) (Photo 2).
4 - Reverse the direction of rotation of the motor.
5 - While pushing on the hose, jog run the motor and check the direction of rotation.
6 - The shoes mounted on the wheel are going to “swallow” the hose and push it out of the inlet port. Always by giving
jolts, a gap is maintained between the hose and ange in order to slide the clamps over the hose and into position.
Once the clamps are placed loosely over the hose, jog the pump to get the hose ush with the ange. (REF 47) (photo 3).
7 - Assemble the clamps (REF 8 and 9) on the inlet side. Clamp (REF 8) is to be mounted on the sleeve to ensure the sealing.
Clamp (REF 9) needs to be installed at an equal distance between the ange and sleeve. Mount the insert (REF 12) into
the hose. Tighten clamps (REF 8 and 9) .
If you meet diculties in introducing inserts into the pump hose,
coat them slightly with ALBIN lubricant. Never use another lubricant.
8 - Assemble the brackets (REF 18) and pre-assemble ange (REF 47) on the outlet side with two temporary bolts.

9 - Reverse the direction of rotation of the motor.
10 - A gap is maintained between the hose and ange in order to
slide the clamps over the hose and into position. Once the
clamps are placed loosely over the hose, jog the pump to
get the hose ush with the ange.
11 - Undertake operation step 7 at discharge side.
12 - Fill the pump with the necessary quantity of ALBIN lubricant
see §6.1 and §9.7.
13 - Take away the temporary ange bolts and x the piping on
both suction and discharge sides.
14 - Open the valves at the suction and discharge sides.
15 - Check the direction of rotation of the pump.
Check for any possible lubricant leakage by the inserts,
sleeves or cover.
FOR MODELS ALH05, ALH10, ALH15
and ALH20
Dismantle the bracket (REF 18). Mount clamp (REF 8)
and 9 on the hose. Mount the insert (REF 12) into the

6.4.2 - REPLACEMENT OF THE SEAL RING (REF 27) AND THE SHAFT SEAL (REF 26)
ALBIN hose pumps are equipped with a leakage channel (refer below image) that allows to see the wear of the seal
ring or thr shaft seal. This channel is at the back of the pump casing underneath the gearbox ange. It also protects the
gearbox seals by leaving the lubricant or the product to pass freely at the back of the pump casing.
