Screw Pumps

DAE Pumps Screw Pumps are designed for pumping light fuel oils such as diesel, kerosene, and biodiesel. It is also possible to pump vegetable oil, motor oil, and glycerol.  These oils have different benefits and drawbacks, making them more or less ideal for different situations.

It is a helical gear pump and a built-in by-pass valve for pumping clean viscous liquids not containing abrasive or solid particles.  This pump is ideal for many applications, including those requiring high flow rates or pressures. The pump’s unique design makes it possible to achieve a wide range of flow rates and pressures, making it an ideal choice for various applications.

DAE Pumps Screw Pumps’ gear oil pumps are suitable for transporting various oils such as petroleum, diesel, and lubricant. When using copper gears, the pumps can converfluids with low flash points such as gasoline and benzene at temperatures below 70℃. They are widely used in oil reservoirs, piers, ships, mining sites, factories, and farms. The Screw Pumps series gear oil pumps are mainly used for transporting viscous lubricants for mechanical equipment. The pumps can pump cooking oils or beverages when equipped with stainless steel gears.
