Rotofluidpumps is a Leading Manufacturer and Supplier of Rotary Gear Pump, Gear Pump, Rotary Gear Pumps, and Rotary 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.
An internal rotary gear pump is a positive displacement pump that employs a rotor and idler gear assembly to generate its flow. The assembly is offset, using a crescent adjacent to the inner gear, all within an outer gear. As the rotary gear pumps drive the idler gear pump, the space caused by the crescent offsetting the gear pump and the meshing of the gear teeth displaces the fluid, expelling it to the discharge port.
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.
