Versatile Positive Displacement Pumps For Varied Media

Positive Displacement Pumps

Industrial pumps play a vital role in the manufacturing process of almost all industries. Every industry has its own set of requirements that the industrial pumps must comply with in order to serve the industries in an efficient manner. Industrial applications might be easy or difficult, and to ensure optimum productivity, the pumps need to be customizable and of the highest quality.

Roto Pumps is a well-known industrial pump manufacturer with more than 50 years of experience in providing quality pumps to a range of industries including paper, food & beverages, paint, sugar, wastewater among others. It reins dominance across five continents and several countries including India, Australia, Germany, UK, USA, South Africa, and Malaysia. These pumps are especially popular as one of the top ten global producers of Positive Displacement Pumps.

As their name suggests, Positive Displacement Pumps or PD Pumps operate on the principle of positive displacement, i.e., trapping a fixed amount of fluid and moving it from the expanding to the shrinking cavities on the suction and discharge ends of the pump respectively. Among Roto’s PD Pumps, the ones that remain in high demand are Twin Screw Pumps, Cavity Pumps, and Food and Beverage Pumps.
Twin Screw Pumps operate with the help of a motor, two screw spindles, timing gears, and a cylindrical compartment. These pumps are used for handling a variety of fluids ranging from lubricated, non-lubricated, and aggressive. Due to no direct metal to metal contact, these pumps have a long and trouble-free life. These pumps are self- priming and are extremely safe to operate owing to their in-built relief valves.

Roto’s Cavity Pumps are built and designed to handle liquids with different viscosity levels and chemical properties. These pumps ensure a uniform, metered, and non- pulsating flow. They do not require a foot valve and can work while being on snore. These can easily handle fluids high percentage of solid elements without getting clogged.

Another distinct feature of these pumps is that they have low NPSH requirements. They facilitate silent running while creating a little noise. These pumps have separate bearing housing so that fluids can be transferred without any contamination.

Roto’s Food and Beverage Pumps are extremely heavy-duty pumps. The metallic parts of these pumps have been made with stainless steel to ensure the highest level of hygiene. These pumps are resistant to oil and fats and have closed universal joints which enables them to handle fluids with a low lubricating value like aerated water. These pumps can be customized with wide throat configuration for highly viscous liquids.
