1.- GENERAL DESCRIPTION
DOSTEC-50 dosing pumps are heavy duty, high precission, piston pumps for
dosing liquid products.
This series allows many injection possibilities depending on the head being
chosen. The available heads are from 330 to 1000 l/h for the piston series, and
from 207 to 870 l/h for the diaphragm series.
DOSTEC-50 dosing pumps are manufactured with materials that can resist
most chemicals products, even acids. They are designed for all sorts of
processes where it is necessary to dose a product into a hydraulic network,
such as: food, textile, chemical industry, water treatments, etc. (See materials
in Technical Features). In case there is any doubt about compatibility of
materials with the products to be used please contact ITC S.L. Technical
Service.
Dosing flow of each module is adjustable independently with no need to stop
the pump from 0% to 100% of its capacity.

4.- OPERATION
The rotational motion of the motor is transmitted by the gear box that consists of
two major components, the pinion (A) and the ring gear (B). The pinion and the
ring gear are linked to an axis with an eccentric bearing (C) that pushes the shaft
(D) which is threaded to the diaphragm or the piston (E). The return movement is
made by the spring (F).
While the pump is running the stroke length can be regulated by the flow regulator
knob (G). It increase or reduce the discharge or suction’s strokes, either the piston
or the diaphragm, changing the injection flow. The dosing flow can be adjusted
between 0% and 100%.
The flow can be adjustable through an inverter, which will vary the engine speed of
the pump and will allow regulate the dosing flow between 10% and 100%.

5.- INSTALLATION
GENERALITIES
To install this pump it is advisable to choose places protected from water,
away from heat sources and with air renewal.
Place the pump vertically over a totally rigid surface to achieve a proper
lubrication of all inner elements. Anticipate which will be the room you will
need to comfortably do the basic maintenance and install / desinstall the
pump.
Fix the pump on the chosen
flat surface by means of 4
screws.

6.- START UP AND REGULATION
STAND: Check that the pump is properly installed in its stand.
OIL: Take off re-filling lid and fill the pump with the provided oil:
SAE 80 W 90 or equivalent.
Check the oil level shown on the oil peep hole

CHECKING THE HYDRAULIC CIRCUIT: Check that all valves are
opened and that escapes from priming valves derive the liquid to a
proper receptacle.
ROTARY DIRECTION: Start up the pump to check that the rotary
direction coincides with the one shown by the arrow. To change rotary
direction invert two phases in the motor terminals box.
CHECKING OF PUMP: Check visually/auditorilly the proper working
of the pump.

DOSING FLOW
Through the micrometic regulator ,we will adjust the dosing flow from 0 to 100%
depending on the wished value. It is not advisable a regulation under 10%.
In order to check the dosing flow:
1.- Prime the pump immersing the suction pipe in a graduated receptacle (A).
2.- Mark in the receptacle the liquid level.
3.- Start up the pump and pour a known volume (V) of measured liquid in a
second receptacle (B).
4.- Measure the time (t) that goes between the start up of the pump and the
precise instant in which the liquid reaches the level of the mark receptacle A.
5.- The dosed flows corresponds to:
Q(l/h) = V (liters) / t (seconds) x 3600
