Positive Displacement Pumps are the most efficient pumps used in industrial applications. These pumps are called so owing to the principle of positive displacement employed in their work. A Positive Displacement Pump contains two cavities on either of its sides. The cavity of the suction end expands while the cavity on the discharge end shrinks as it operates. Once the liquid is lifted inside the pump, it flows from the increasing cavity to the decreasing one. These pumps function with the constant repetition of this cycle. These pumps deal with a fixed amount of liquid in each of the cycles. Therefore, they produce a uniform flow of the media at the given speed, irrespective of the level of discharge pressure.
Roto Pumps is a renowned Positive Displacement Pumps manufacturer and ranks among the top ten producers of PD Pumps in the world. Their Chemical Dosing Pumps and Food Grade Pumps, both two different kinds of efficient Positive Displacement Pumps, are known for their efficient working and extreme reliability in handling the hygienic and safe transfer of media.
A Chemical Dosing Pump is widely used to handle the transfer of clean and clear fluids. These pumps are most suitable for applications demanding high accuracy and repeatability. These pumps are also known to ensure the smooth and non-pulsating flow of the liquids. Roto’s Chemical Dosing Pumps are suitable for both intermittent and continuous dosing duties. They can also efficiently handle the low flow applications with pressure as low as 0.68 LPH. Their machinery consists of Dry Running Protection Device, Pressure Switch, Gauges – Pressure, Vacuum, and Differential, Relief Valves and Strainers.
As its name suggests, A Food Grade Pump is generally used to handle the transfer of food items such as ketchup, jam, yeast, butter, etc. Roto’s Food Pumps are capable of transporting highly viscous liquids and thick pastes and food items. These shear-sensitive pumps transfer the food items without affecting their quality and edibility. The highest standards of hygiene and safety are maintained during the operations. The parts of the pumps that come in direct contact with the food items are made out of smooth finished stainless steel. The parts of these pumps are easy to clean and maintain. Roto’s Food Grade Pumps come with metal bonded aseptic food-grade elastomeric stator. The advantage of this stator is that it is resistant to oil and fats and prevents them from sticking to its surface.
