Positive Displacement Pumps to Handle Varied Media

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. 

Robust Industrial Pumps and Retrofit Spare Parts

Roto Pumps produces and supplies one of the best quality industrial pumps and retrofit spare parts in the market. They provide interchangeable rotors, stators, shafts, coupling rods and universal joint kits. Among several high-quality pumps provided by Roto, Wastewater Pumps and External Gear Pumps are known to be highly efficient and durable.

Roto Pumps is one of the leading Wastewater Pumps manufacturers. As their name suggests, Wastewater or Sewage Pumps are used to handle the transportation of dirty and contaminated fluids such as waste water, sewage and sludge. These kinds of applications are required in several projects such as to transfer industrial waste water, to treat the waste water to be reused, to treat the waste in sewers, to handle municipal water, to control and manage excess water due to floods and dewatering. The body and machinery of these pumps are made of robust material as the fluids usually handled by these kinds of pumps is highly corrosive and aggressive. The electric motor helps to run the pump. The pump is also equipped with a chopper impeller that rotates and lifts the materials inside the pump. This impeller is fitted with sharp blades that keep on chopping down the solid waste among the sewage to avoid blockage and assure the perfect functioning of the pumps. The impeller is fixed inside a casing whose surface is lined with tough material to prevent any damage to the body of the pump.

An External Gear Pump is a Positive Displacement Pump that operates with the help of two gears, hence its name. Both the gears are fixed inside a casing with interlocked teeth. A motor is used in these kinds of pumps as well to run the pump. The energy provided by the motor helps to move one of the gears. The movement of this gear compels the other gear to move in the opposite direction. This movement helps to lift the liquid inside the pump and makes it moves axially before discharging it from the other end of the pump.
