Dosing pumps

Dosing pumps

Dosing pumps can be used in almost all industries to transfer precisely at very low capacity. These pumps are suitable for pumping with low volatility for the transport of diluted materials to highly viscous materials with solid particles or chemicals that have chemical corrosivity.

Capacity: from 1 lit / h to 1000 lit / h (more capacities are custom made).
Pressure: Up to 20 bar (additional pressures are custom made).
These pumps are made of small size car with a motor and gearbox.

The actuators of these pumps are electrically powered (electromotor), solar (electromagnetic), hydraulic or pneumatic.
It is important to note that in the centrifugal pumps, the pressure changes, the discharge also changes, so it is not suitable for use as a dosing pump.


Dosing Pump Equipment and accessories 

Most dosing pumps have a safe valve for protection, which act at an outlet pressure when the excess is exceeded.

Pulse Dampers

dosing pumps are positive displacement pumps and thus output pulses. By these modulators (dampers), the flow of the output becomes closer to the linear and constant state.

Back Pressure valves

            In cases where difference in pressure and discharging pressure is less than 1.5 times, it is used. This type of valve causes the fluid to flow out due to the low pressure of the thrust line.


At the beginning, the pump is installed and prevents the introduction of particles and contaminants to the pump.
