Chemical Dosing Pumps

EZIDOS K Series Pumps

Our EZIDOS K series solenoid driven diaphragm metering pumps provide you with a wide choice of dosing application. These pumps can be supplied as either manual-venting or self-venting. When being used to dose chemicals that have a tendency to gas off we recommend the self-venting models.

The self-venting models siphon around 20% of the delivery back into the chemical drum so consequently they deliver slightly less than the manual venting models.

Pumps within this range are all foot mounted. If you require wall mounted models see our V series range instead. However, we do supply pump brackets for the K series that allow mounting on a wall.

Each model in the range is available for duties between 1L/Hr and 18L/Hr and for pressures between 1Bar up to 20Bar.

Our stock models include;
1L/Hr - 20 bar
2L/Hr - 18 bar
5L/Hr - 10 bar
8L/Hr - 8bar
10L/Hr - 5 bar
18L/Hr - 2 bar
20L/Hr - 1 bar

EZIDOS V Series Pumps
The EZIDOS V series solenoid-driven metering pumps are the perfect solution for medium dosage need.
Wall mounted, they are equipped with microprocessor technology and stroke speed adjustment. All liquid ends are in PVDF, but pump head and accessories in PP and EPDM and hose in PE are available on request.

Pump head is available with manual or self venting option.

Our stock models include;
1L/Hr - 20 bar
4L/Hr - 15 bar
6L/Hr -   7 bar
10L/Hr - 3 bar
16L/Hr - 1 bar

EZIDOS AMS Series Pumps

The EZIDOS AMS range of chemical dosing pumps are constant or proportional dosing pumps with level control for chemical feeding into water.
In Constant dosing mode pump doses a constant quantity regularly as configured by the user.
In Proportional dosing mode pump doses a quantity proportionally to an input signal, digital (voltage free contact) or current (mA).

Working modes available:
• constant
• constant with 1-10 pulses divider
• multiplier with 1-10 pulses divider
• divider with 1-10 pulses divider
• divider with 1-100 pulses divider
• divider with 1-1000 pulses divider
• mA current signal (0/4 mA = 0 pulses: 20mA = max pulses)

Flow rate is determined by the stroke length and by the stroke speed. The stroke length is adjustable from 0 to 100% using the stroke length adjustment knob. However dosing accuracy is guaranteed within an adjustment range from 30% to 100%.  

Our stock models include;
5 l/h at 25 bar
10 l/h at 15 bar
15 l/h at 10 bar
20 l/h at 7 bar
40 l/h at 3 bar
60 l/h at 2 bar


AMS CO PLUS works in constant mode. The pump can be set to work in
• constant
• constant with 1-10 speed reducer.


The AMS CL PLUS works in constant mode and has got level control. The pump can be set to work in • constant • constant with 1-10 speed reducer.


The AMSPLUS Range are solenoid-driven metering pumps that are a perfect solution for high-dosage need.

They are foot mounted and equipped with microprocessor technology and manual stroke length adjustment. All liquid ends are in PVDF, but pump head and accessories in PP and hose in PE are available on request. The pump head is available with manual or self venting.

AMS PLUS, with constant/proportional dosing system, has level control, digital signal, current signal and the following working modes:
constant/constant with 1-10 divider,
1-10 pulses multiplier,
1-10 pulses divider,
10-100 pulses divider,
100-1000 pulses divider
and mA current signal (0/4 mA = 0 pulses: 20mA=max pulses).

In terms of delivery this range will deliver from 5 litres / hour at 25 bar up to 60 litres / hour at 2 bar. The self-venting models deliver around 20% less than the manual venting models as a result of the venting process.


AMSA is the AMS version with self-venting pump head. A self-venting pump head must be used when using chemicals that produce gas (i.e. hydrogen peroxide, ammonium, sodium hypochlorite in particular conditions). 

Multifunction motor-driven pumps

Our range of multifunction motor driven pumps are designed for industrial dosing needs.

The PRIUS MF line, available with membrane or piston, has an electronic unit that can control and manage the dosing process according to
10 different working modes.

The electronic unit can be mounted in two positions: frontal or rotated. Different pump heads enable the pump to handle the most aggressive
chemical agents. The display and the graphical interface simplify pump programming and management.

These pumps are also available in a high pressure version enabling a wider range of applications.
