Positive Displacement Pumps For Diverse Applications

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.

Efficient and Robust Industrial Pumps for Difficult Applications

Roto Pumps is one of the leading Air Operated Double Diaphragm Pump (AODD Pump) manufacturers and suppliers. These pumps are used for pumping applications requiring smooth and non-pulsating flow of fluids. These kinds of pumps are extremely easy to operate and maintain, so they don’t need any specialized expertise to be run. They are also highly cost-effective. A feature that sets these pumps apart from other kinds of pumps is that they can function with the assistance of compressed air instead of an electric motor. AODD pumps are self-priming in nature, i.e. they have the ability to transform an air or water mixture into a pumpable liquid. They are also capable of handling operations involving irregular suction conditions by being able to run dry.  Roto’s AODD Pumps are available in a variety of materials including aluminum, PVDF, ductile iron, stainless steel and Teflon.

Roto Pumps is also one of the topmost Chemical Dosing Pump manufacturers. It is a kind of a Positive Displacement Pump. The Chemical Dosing Pumps are compact in size. They are built and designed to handle precise dosing applications. These pumps are also used to facilitate the infusion of specific chemicals into liquids, steam and gas. These pumps also take care of dispensing of chemicals through an automated procedure.

Slurry Pumps are another kind of efficient pumps provided by Roto Pumps. A Slurry Pump is a pump that is heavy-duty in nature as it is meant to handle the transportation of corrosive and abrasive liquids containing solid constituents of varied shapes and sizes and varying compositions; also known as slurry. That’s why their bodies are constructed with strong and sturdy material to avoid any wear and tear caused due to the nature of the materials handled by these kinds of pumps.  An important factor contributing to the efficient working of these low maintenance and easy-to-use pumps is their easily replaceable parts.
