To cater to a wide spectrum of industries such as sugar, agriculture, chemicals, mining, pharma, wastewater, and many more, Roto Pumps continuously provides highly efficient and robust Positive Displacement Pumps. The Progressive Cavity Pumps and Twin Screw Pumps fall under the category of Positive Displacement Pumps.
The Progressive Cavity Pump is designed to efficiently facilitate the flow of different types of media. It can be easily customized to meet the specified requirements of the customers. The rotor in the Progressive Cavity Pump is attached to the stator. When the machine starts, the rotor that is inside the stator turns with the stator. A sealing line is formed along with the rotor. The movement of the rotor and stator creates cavities that facilitate the flow of media from suction to discharge end. The Progressive Cavity Pump can handle pressure up to 80 bar.
Roto Pumps is the leading Progressive Cavity Pump Manufacturer. High-Pressure Progressive Cavity Pump is also known as Single Screw Pump. This pump caters to various industries such as shipping, chemical, ceramic, paper, wastewater, paint, oil & gas, and many more. Some of the benefits of this pump are that it can convey abrasive, non-abrasive (with or without solid particles) media with ease. It is non – clogging, which means that it facilitates a smooth flow of media. This pump is reversible, which means that it can perform efficiently in either direction. It works on the principle of positive displacement and generates less noise.
Roto Gear Timed Dual – Flow Twin Screw Pump is dependent on the rotation of two screw spindles in a closed compartment. The timing gears are fitted at the end of the spindles that help to pull the media in from the suction end. When the motor starts the fluid enters from the suction end and gets entrapped in the bore of the pumping compartment, in the center, and the flanks of the screws. It then smoothly passes towards the discharge end. Some of the features of the Twin Screw Pump are that there is no metal to metal contact between the pumping elements. This leads to long and hassle-free service life. It has a low NPSHR due to which it provides high volumetric efficiency. It is self-priming and has a uniformed metered flow which conveys lubricating/non-lubricating and aggressive liquids. It is built to bypass 100% capacity and has an in-built valve that makes it safe to operate.
