Positive Displacement Pumps to Handle Varied Media

by Sandeep Pandey Blogger

Positive Displacement Pumps are the most common types of pumps and are used for a varied range of applications. These kinds of pumps are extremely versatile and can be used to handle both smooth and aggressive media. These pumps work on the principle of positive displacement, according to which the flow rate is generated when the space during an application is reduced and increased. One of the best quality Positive Displacement Pumps available in the market are provided by Roto Pumps. Roto Pumps are among the top ten Positive Displacement Pumps manufacturers in the world. One of the best kinds of PD pumps provided by Roto are the External Gear Pumps.

 

External Gear Pumps provided by Roto are simple and compact. They are capable of generating high pressures and are available in a simple four-piece design. An ideal External Gear Pump can be chosen for an individual application as they are provided in a variety of materials like cast steel, cast iron and duplex steel. These pumps are capable of handling the transfer of highly viscous and abrasive liquids in an efficient manner. Several industries use these pumps in their day-to-day applications such as oil, chemical and FMCG industries. These pumps use the movement of two gears located inside a casing to pull the liquid inside the pump. Once inside, the liquid is directed towards the discharge end of the pump through the vacuum created between the intermeshing teeth of the two gears and the casing.

 

Roto Pumps is also one of the leading Wastewater Pumps manufacturers. Roto’s Wastewater Pumps are used to transfer unclean liquids with solid elements such as sewage and sludge. That’s why these pumps are also known as Sewage Pumps. The solid elements contained in these kinds of media can be organic or inorganic. This makes this media highly aggressive to be transported. Due to the need for transporting this media regularly, the body of the wastewater pumps needs to be extremely strong. This makes these PD pumps highly efficient and useful for difficult applications like the treatment of sewage or wastewater treatment and transportation. They are also used in mining and construction industries among others.

 

Besides External Gear Pumps and Wastewater Pumps, Roto Pumps are also known to be one of the best Air Operated Diaphragm Pump manufacturers in the market. AODD Pumps is one of the most efficient Positive Displacement Pumps. These kinds of pumps are known to ensure a smooth and low-pulsating flow of liquids. They are extremely low-maintenance and can function with the help of compressed air instead of an electric motor. Roto’s AODD Pumps are available in aluminum, PVDF, ductile iron, stainless steel and Teflon.
