Dosing Pumps – The best choice for precise metering applications

These pumps are developed for low flow applications that demand high accuracies and repeatability with unique advantages of smooth and non-pulsating flow. These pumps can handle clean and clear liquids.

The pump is ideal for either intermittent or continuous dosing duties. These pumps can handle minimum flow as low as 0.68 LPH to 500 LPH & ensure proportionate dosing of media.

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.

 

Strainers:
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.
