1.- GENERAL DESCRIPTION
DOSTEC-40 dosing pumps are heavy duty, high precission, electric diaphragm
pumps for dosing liquid products.
This series allows many injection possibilities depending on the head being
chosen. The available heads are: 25, 50, 100, 200, 300, 500 l/hr for the piston
series, and 25, 50, 100, 200, 300 l/hr for the diafragme series.
DOSTEC-40 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.

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.

4.- OPERATION
The electric motor (B) transmits its power by means of a reducer, made up of a
pinion (E) and a ring gear (F) solidary to an axis (I) and an eccentric (A) that
alternatively pushes and draws a shaft (C) threaded to the diaphragm (D).
The micrometic regulator (G) increases or diminishes the stroke of the shaft and the
diaphragm by means of a threaded pipe coupling (H), modifying the injection flow.
The dosing flow is adjustable from 0% tol 100%.
To regulate by means of an inverter is possible varying proportionaly the dosed flow
by the frequency supplied by an electric motor. The dosing flow is adjustable from a
10% to 100%.
