How Gear Pump Works? In Gear Pumps, two gears working together are mounted in a body. The gear connected to the drive shaft drives the idler gear. The vacuum formed by the movement of the gears working with each other at the small tolerances of the body carries the fluid into the pump. The fluid that fills into the gear cavities proceeds towards the pump outlet under the pressure created by the sliding rolling motion of the gears with each other. Gear pumps can operate in both directions. Transfered Liquids: Alkyd, Asphalt, Acids, Honey, Vegetable Oils, Bitumen, Paint, Glass Water, Chocolate, Detergent, Melted Rubber, Fuel-Oıl, Glucose, Glycerine, Gress, Animal Oils, Isocionate, Gel, Gelatin, Cocoa Yağo, Tar, Caustics , Cream, Mineral Oils, Printing Ink, Molasses, Diesel Oil, Naphtha, Paraffin, Petroleum Products, Poiol, Polyester, Resin, Soap Raw Material, Hot Oils, Solvents, Shampoo, Syrups, Sweeteners, Toluene, Glue, Varnish, Wax, Olive Oil . Gear Pump General Features: Flow rate: 0,5 - 200 m³ / h Pressure: 0 - 15 BAR Performance: With positive displacement, the pump pressure increases and the flow decreases slightly. The flow increases as the pump speed increases. NPSH: 0 - 6 meters Fluid: In all viscous fluids that do not contain hard particles Noise: Quiet with helical gear design. Power: Power increases with increasing Speed and Pressure. Discharge Line: By-pass is absolutely necessary in Discharge lines that may be closed. Temperature: Carbon Mattresses (-40 / 300 ° C) - Bronze Mattresses (-40 / 180 ° C) Viscosity: max. 100,000 SSU Sealing: Graphite, Teflon, Braided Seals - Mechanical Seal Production Types: By rusty - Without rust With steam jacket - Without steam jacket Bearing Plain Bed Outboard Bearing External Slip Bed All machinable metals Gear Pumps Installation and Commissioning Coupling adjustment should be checked. The suction pipe must be airtightly connected and the pump must be protected from dirt using a suitable filter. The suction line is 15 m. In fluids with a length exceeding 10000 SSU; suction pipe, pump, one or two pipe sizes should be larger. Compensator should be placed in suitable places to prevent additional load on the pump due to the installation. When braided graphite packing is used; seal pressure should be adjusted to flow 15-20 drops per minute. The suction circuit must be filled with fluid at the first start. During the first start of the pump; The pump shaft is turned by hand several times. Although they work in both directions, they work quietly in the OK direction. Pumps with By-Pas must be operated in the direction of OK. For this reason, the direction of rotation should be checked. Coupling adjustment should be checked The valves on the pipeline should be open. The pump is ready for operation if the above conditions are met.
