Rotary Gear Pump, Gear Pump - Rotary Pump Manufacturer in India

Rotofluidpumps is a Leading Manufacturer and Supplier of Rotary Gear Pump, Gear Pump, and Foam Rotary Gear Pump in India. it is widely used in the chemical plants and at all the other places where the viscous and semi-liquids are utilized.

Fluid Tech Systems offer “ROTOFLUID” brand Rotary gear pump Model “FT” (Rotary Gear Pump) which is self priming, foot mounting type positive displacement Rotary Gear Pump. Model “FT” having simple two pieces Cast Iron construction which is single helical modified profile carton steel gear shrink fitted on alloy steel hardened and grind finished shaft as gear firmly supported 4 nos. of self lubricated sintered bronze bush bearing which ensure smooth running. Rotary Gear Pumps can be run in either direction with change in inlet-outlet port position. The relief valve operations can be reversed by simply changing the R.V. parts on opposite side.

The suction and delivery connections are available in 1/4" to 3" sizes. Rotary Gear Pumps can be operated up to pressure of 10 kg/cm² with 5 LPM to 500 LPM flow capacity. Rotary Gear Pumps are designed to run at 1440 RPM up to viscosity of 50,000 to 1,00,000 SSU and maximum temperature up to 200ºc. It is desirable to reduce speed for size above 1½" performance at low speed is always advantageous as it improves efficiency, reduce noise level and enhances operational life. The capacity will reduce in proportion to the speed.

FAQ

A positive displacement pump which also known as rotary gear pump uses the meshing of gears to pump fluid by displacement. As the gears rotate, it develops a liquid seal and creates suction at the inlet. As a result, fluid is drawn into the pump, and then the space between the rotating gears expels the fluid via the discharge port. The design of a rotary gear pump can handle high temperatures and high-pressure applications.

Method of classification is various but some of the basic gear pump designs are classified into two types internal gear pumps & External gear pumps.

External Gear Pump: These pumps are simple and solid in design and are sufficient to distribute high capacity of fluid. It manage all kind of pressure like low, medium and high.

Internal gear pumps: compare to external gear pump this can be run for a small phase and net positive suction head requirement is very low.

Some other types are
Lobe Pump
Screw Pump

Service and maintenance is very simple for gear pumps. Cavitation are less sensitive, easy to reconstruct and output is controllable.
Cost-effective option
Easy to use and maintain
Insensitive to fluid viscosity and density

Gear pumps are chosen for a high force o/p is necessary and are usually used for
Bitumen and tar
Chocolates, fats, and oils
Soap and personal care products
Resins and polymers
Fuel and lubricants
Solvents etc.

internal and external pumps are commonly used in different fuel, lube oils, solvents and alcohols The external pumps are used in chemical preservative, polymer metering, mixing and blending of chemical, agriculture, industrial, and mobile hydraulic applications.
