Gear Pump

Features

- As an external gear coated with special rubber and an internal gear made of MC Nylon, Teflon, PP, or PE are used, the gears don’t easily wear out making it last longer.

- No noise and vibration when the shaft rotates with high speed.

- Little space is required for installation and it is easy to be moved as the motor and the pump are directly connected.

- Wide range of fluids from the low viscous liquid such as water to the high viscous liquid can be transferred with high pressure.

- Chemicals containing sludge and mixture with sands can be also transferred with high speed.

- The mechanical seals can be mounted in pair.

- When making it as a multistage pump, the liquid containing much sludge can be transferred with constant pressure and flow rate for a long period.

Applications

- Inviscid liquid: water, seawater, water supply in a high-rise, high pressure cleaning machine, fountain, golf course, sprinkler, crop spraying, filter press dehydration, etc.

- Viscous liquid: lubricant, gear fluid, hydraulic oil, bunker fuel oil C, waste oil, cutting oil, grease, paint, varnish, sealant, glue, etc.

- Oil: petroleum, gasoline, light oil, thinner, solvent, toluene, alcohol, benzol, acetone, methanol, rolling oil, etc.

- Chemical: hydrochloric acid, sulfuric acid, nitric acid, acetic acid, phosphoric acid, chloric acid, sodium hydroxide, ferrous chloride, ferric chloride, ferrous sulfate, cupric sulfate, copper chloride, etc.

-Food: pastes, soy sauce, cooking oil, sesame oil, honey, curry sauces, cream, mayonnaise, ketchup, tofu, fruit juices, beer, etc.

How It Works

- Liquid enters the suction port between the rotor (large exterior gear) and idler (small interior gear) teeth.

- Liquid travels through the pump between the teeth of the "gear-within-a-gear" principle. The crescent shape divides the liquid and acts as a seal between the suction and discharge ports.

- The pump head is now nearly flooded, just prior to forcing the liquid out of the discharge port.? Intermeshing gears of the idler and rotor form locked pockets of the liquid which assures volume control.

- Rotor and idler teeth mesh completely to form a seal equidistant from the discharge and suction ports. This seal forces the liquid out of the discharge port.
