Before carrying out any service on the item, check:
Disconnect the pins from the mains or by means of a two poles switch with 3 mm minimum distance between the

contacts.
Relieve all the pressure from the peristaltic pump and injection tube.

Drain or flush all dosing liquid from the peristaltic.

In case of any losses in the hydraulic pump (rupture of the injection valve, filter, pipes), you have to stop operation of the
pump depressurize the discharge pipe and then proceed with the maintenance using appropriate security measures (gloves,
goggles, overalls, etc..). Dosaggio di liquidi nocivi e/o tossici.

T o xic an d /o r d an g e ro u s l iq u id d o sag e

To avoid risk from contact with the hazardous liquids or toxic fumes, always adhere to the notes in this instruction manual:
Follow the instructions of the dosing liquid manufacturer.

Check the hydraulic part of the pump and use it only if it is in perfect condition.

Use only the correct materials for the tubing, valves and seals to suit the liquid to be dosed; where possible shield the

tubing with PVC conduit.
Before disconnecting the metering pump, make sure to flush out and neutralize the pump head with the proper reagent

liquid.

Ass em b l y

All metering pumps are normally supplied fully assembled. For greater clarity, please consult the exploded view of the pump
appended at the end of the manual, which shows all the pump details and a complete overview of all the pump components.
These drawings are in any case quite indispensable whenever defective parts have to be re-ordered. For the same purpose, the
appendix also contains other drawings showing the hydraulic parts (pump head and valves).

Dism an t l em en t

Proceed as follows before you dismantle the pump or before performing any other operation on it:
Disconnect the pins from the mains or by means of a two poles switch with 3 mm minimum distance between the

contacts.
Relieve all the pressure from the peristaltic pump and injection tube.

Drain or flush all dosing liquid from the peristaltic.

This operation calls for special attention, and you should therefore consult the drawings in Appendix and Chapter "RISKS"
before you commence work.

PERISTALTIC PUMP EPOOL SERIES

Op e rat in g p ri n cip le

Peristalsis is a wave of automatic contractions propelling contents along channel or tube, this led to a peristaltic action. By
mechanical simulation of biological peristalsis rollers crush tube walls togheter to form a seal while roller moves along the tube,
then the previously compressed tube regains original form and sucks fluid into the formed vacuum. The fluid will follow the roller
until tube is not compressed any more, then to avoid a flow back a second roller compress the tube, pushing the fluid out of the
pump and repeating the suction action while the pump continues to operate the rollers which are fitted on a special rotor create
suction lift and outlet pressure.
