Positive Displacement Pumps are the most commonly used industrial pumps across a number of industries. Roto Pumps is one of the top ten manufacturers and suppliers of Positive Displacement Pumps in the world. Some of the most efficient PD pumps manufactured by Roto Pumps are discussed here.
Progressive Cavity Pumps are quite common in several industries owing to the wide range of applications they can cater to. These pumps can easily handle applications involving liquids with both high and low viscosity, i.e. the thick consistency between liquids and solids. Another feature that makes these kinds of pumps suitable for a varied range of applications in terms of the rate of flow and pulsation is that these pumps can be customized to suit the needs of the individual projects. These pumps are also ideal for projects requiring large pumping applications. Roto’s Progressive Cavity Pumps are provided with small cavities, a double helix elastomer stator, and a single external helix rotor which helps the pump to operate. The water passes through the cavities to the discharge end of the pump once it is lifted through the suction end.
Another kind of efficient PD Pump provided by Roto Pumps is a Helical Rotor Pump. These pumps consist of a helical rotor and a helix rubber stator. The liquid is lifted inside the pump with the movement of the rotor inside the stator. It keeps on lubricating the rotor while moving on the surface of the stator. These pumps are very sensitive in their operation and are capable of transporting the media without affecting its quality or causing any wear and tear to the pump.
A High-Pressure Slurry Pump is also a kind of PD Pump that specializes in transporting unclean liquids with solid waste elements. Their robust bodies deal with this kind of an abrasive liquid efficiently. The parts of these pumps are also easily replaceable in case of any wear and tear. This promotes the smooth functioning of the pumps under all circumstances.
