Valve

Helical and spur gear pumps are used for the transfer of low, medium and high viscosity liquids. They are similar to pumps with internal camshafts in that the gears are intertwined and separated to ensure fluid transfer. But in these pumps, the gears are identical and rotate mutually. Since their internal cavities are narrow, a more reliable and controlled fluid flow is provided. Therefore; Suitable for sensitive transfers and metered use involving asphalt polymers, fuels and chemical additives.

Gear pumps can work with the same efficiency in both directions. When the discharge direction is changed in by-pass pumps, the by-pass direction must also be changed. Thanks to its positive displacement, it can reach high pressures even at the lowest speeds and high efficiency can be obtained at low flow rates. Since the flow rate and the speed are approximately directly proportional, the desired flow rate can be easily achieved by changing the speed. All liquids with viscosities between 38 ssu and 250,000 ssu
