To avoid personal or enviromental damages and to guarantee a proper

operation of the equipment, the staff in charge of the installation, set up and

maintenance of the equipment must follow the instructions of this manual,

specially those recommendations and warnings explicitly detailed. In addition,

specific instructions for the chemical products to be dosed should be followed.

Unit (ACU)

Encoder

Additional ventilation

Block

Suction valve

Cylinder

Injection valve

Dostec AC is a diaphragm or piston dosing pump with advanced control for an

accurate and efficient automatic dosing.

This series allows many dosing possibilities depending on the chosen head.

The flow range covers from 3 to 1200 l/h (317 gph) up to pressures of 20 bar

(290 psi). The correct selection of head's materials, PP, PVDF or S.S., makes

this pump suitable for the most chemicals products used in water treatment,

chemical industry, food and beverage and agriculture.

Operation modes

Manual: manual flow adjustment through the keyboard

Analogue: dosing flow proportional to a 0/4-20mA signal

Proportional to flow: proportional dosing to a water flow

Proportional to pulses: stroke frequency proportional to input pulses

Batch control, by volume: Dosing a defined volume, after a manual, remote or

time pre-set start.

Batch control, by time: Dosing for a defined time, after a manual, remote or

time pre-set start.

ModBUs: dosing control through ModBus RTU protocol

Inputs and outputs

• Analogue input 0/4-20mA

• External pulse input

• Remote on/off input

• Level sensor input (pre-empty)

• Level sensor input (empty)

• Leakage detector input

• Flow detector input

• Pressure sensor input

• Serial port RS-485 ModBus

• 4-20mA output for register and monitoring

• Pulse output for register, monitoring and

2nd pump control

• Alarm output (relay)

• Level alarm output (relay)

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 throated to the diaphragm or the piston (E). The return movement is

made by the 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 according to the operation mode selected in the

Advanced Control Unit, the dosing pump adjusts the flow to the required value

within the range from 10 to 100% of the rated flow.
