What is a Dosing Pump
Dosing pumps deliver a very precise flow rate of an additive into a flow of water, steam or gas. This dosing application is generally used to change the chemical charactoristics of a fluid.
Applications for Dosing Pumps
Dosing pumps are implemented across a number of industries including (but not limited to): Drinking water treatment, Wastewater treatment, Cooling water treatment, Washing systems, Process water treatment and the Chemical industry.
Classes of Dosing Pumps
Diaphragm Pump Electric
A Diaphragm Pump driven by an electric motor is a more energy efficient and low maintenance solution as compared to air operated diaphragm pumps. They are ideal for applications that require low pulsation and a smooth flow.
Diaphragm pumps are a class of positive displacement pump.
Dosing pumps can be set to discharge exactly the quantity of dosing liquid required for the required application.
Applications include drinking and waste water treatment, industrial applications and the food and beverage industry.
A gear pump employs a system of meshing of gears to move fluids. Because of the mechanism involved gear pumps qualify as positive displacement pumps. For every revolution the gears in a gear pump make the same amount of fluid is moved.
Due to their design, gear pumps are often used for transporting high viscosity fluids, especially in the chemical industry.
Helical Rotor Pump
The helical rotor pump is a class of positive displacement pump that works by the rotation of a helical rotor pushing discrete quantities of liquids through the pump.
A corkscrew-like action provides a pulse free flow where an accurate flow rate is determined by the rotor speed allowing for the helical rotor pump to also be used as a dosing pump.
Peristaltic pumps are a class of positive displacement pumps that used for products that are too corrosive, abrasive or viscous for other pumps. They have no seals, valves or glands and are economical to maintain.
Self Priming Pump
A Self-Priming pump is a type of pump that is designed to be able to lift fluid from below its suction without the need of a foot valve, or hydraulic column of fluid in the suction line.
The pump operates with the aid of fluid in the pump volute.
