Descripción de producto
It is made up as follows:
1. GENERAL DESCRIPTION
Dostec AC is a diaphragm or piston dosing pump with advanced control for an accurate and e󰀩cient
automatic dosing.
This series allows many dosing possibilities depending on the chosen head. The ow range covers
needs from 3 to 1200 l/h at a pressure of up to 20 bar. The choice of the correct head material between
PP, PVDF and stainless steel allows the dosing of any commonly used chemical in the water treatment,
chemical, food and agriculture industries.
Operating modes
Manual: manual adjustment by keyboard of the ow rate to be dosed.
Analogue: dosing proportional to a 0/4-20 mA analogue signal.
Proportional to ow rate: dosing proportional to a water ow rate.
Proportional by pulses: stroke frequency, proportional to input pulses.
Batch control by volume: dosing a given volume. Manual, remote or timed activation.
Batch control by time: dosing for a given time. Manual, remote or timed activation.
ModBus: Dosing control via ModBus RTU protocol.

4. OPERATION
The rotational motion of the motor is transmitted by the reducer, which consists of two major components,
the pinion (A) and the ring gear (B). The pinion and the ring gear are linked to a shaft with an eccentric
bearing (C) that pushes the shaft (D) which is throated to the diaphragm or the piston (E). The return
movement is made by a spring (F).
A high resolution encoder (G) checks the instantaneous position and speed and allows the Advanced
Control Unit to do a close loop adjustment for torque and rotation speed.
By changing the motor speed and depending on the operation mode selected in the Advanced Control
Unit, the dosing pump will adjust the ow to the required value within the range from 10 to 100% of the
rated ow.
