Positive Displacement Pumps For Diverse Applications


Helical Rotor Pump
The Positive Displacement Pumps are versatile pumps that operate on the principle of positive displacement, i.e. holding a fixed amount of liquid in the expanding cavity and moving it through the shrinking cavity.

A range of PD Pumps follows this principle in their working.  

A Chemical Dosing Pump is one such pump. The Chemical Dosing Pump is a compact pump that is widely used to facilitate precise dosing. These pumps are primarily used to dispense chemicals, and inject the chemicals into water, gas or steam. An electric motor powers these pumps. A controller also forms a part of their machinery. It helps to control the flow rate of the liquid and turns the pump on and off.

One of the best Chemical Dosing Pump manufacturers is Roto Pumps whose Dosing pumps can successfully deal with applications with the minimum flow of up to 0.68 LPH. The highest flow handled by these pumps is 500 LPH. They can easily handle the pressure up to 24 bar.

Another kind of efficient PD pump manufactured and supplied by Roto are Helical Rotor Pumps which are used to transfer difficult media. A Helical Rotor Pump is known for its exceptional hydraulic capabilities. These pumps are highly popular owing to their ability to generate high pressures at low speed. They are widely used to handle shear-sensitive media as they can transport fluids without negatively affecting their quality and nature. This feature makes them highly suitable for the food industry. These pumps are extremely robust and work with the help of a helical rotor and a rubber helix stator.

The High Pressure Slurry Pump is another kind of PD pump that is used to handle the transport of difficult media. However, unlike Helical Rotor Pumps, they are used to transport unclean semi-liquids known as slurry. These pumps are powerful in their built as the nature of the media they are used for is highly aggressive.

The Slurry Pumps manufactured by Roto are incredibly economical and low-maintenance. They function with the help of a steel or elastomer impeller and a robust outer casing.

Qualitative PD Pumps for Clean and Unclean Media


Positive Displacement Pump
The 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 help 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.
