Chemical Dosing Pumps Manufacturers


Rising from the category of positive displacement pumps, Chemical Dosing Pumps are the most popular option for a variety of industrial needs. They have a diverse and crucial role to play in the functioning of the dosing system used by a wide range of industries including wastewater treatment. With the major benefit displayed with the displacer forming the vacuum along with the relative pressure applied in the front of automatic suction, they are known for their airtight and dry running performance. An extremely useful feature of these pumps is seen with the precise metering working upto the pressure range of 1200 bars to 3500 bars at the maximum.

Chemical Dosing Pumps – The best choice for precise metering applications

Designed and built to handle a smooth and non-pulsating flow, Dosing pumps are the best choice to ensure high accuracies and repeatability. If you are looking for pumps most suitable for low-flow applications, then these kinds of pumps are your best option as they can handle the capacity of a minimum flow of 0.68 LPH. The maximum flow that these pumps can handle is 500 LPH. They can handle the pressure up to 24 bar. They are also the best choice for precise dosing applications. Chemical Dosing Pumps ensure both intermittent and continuous dosing duties and proportionate dosing of media. They are best suited for transferring clean and clear fluids.

Dry Running Protection Device:
To prevent the stator damage due to dry running specially developed temperature sensor is screwed into the stator wall to monitor the operating temperature. Due to any reason if the pump runs dry, the stator temperature will increase. Roto DRP would switch off the pump at preset temperature.

Pressure Switch:
To prevent the pump from damage due to over pressurization in the discharge as well as low pressures beyond the capability of the pump. This system trips the pump and protects the pump as well as the system.

Gauges (Pressure, Vacuum, and Differential):
These devices are especially important for the system with dynamic working characteristics, that require constant monitoring. The selection of gauge requires consideration of process, environment, accuracy, dial size, connection & mounting. It is advised to limit the normal working pressure to 25-75% of the scale of the gauge.


Relief Valves:
In addition to relieving excess pressure from closed-top vessels or piping systems, these normally closed valves provide system control benefits. It is versatile and widely utilized valve. Its compact size, ease of setting, readjustment and repeatability, all contribute to its popularity. The pressure setting is done manually.


A Strainer is an inexpensive “insurance” for protecting pumps. There is often unwanted matter present which can cause serious problems. Dust, foreign matter, or even clumps of product itself, can clog or damage critical & expensive equipment. Another factor to consider is the cost of downtime.
