    Product Description

    product overview

     W-type vortex pump has compact structure, beautiful appearance, small size, low noise, reliable operation and convenient maintenance. Can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photographic printing and other units pumping acid, alkali, oil, rare precious liquid, venom, volatile liquid, and circulating water equipment, filter equipment. Especially easy to leak, flammable, explosive liquid pumping, choose this pump is more ideal.

    product feature

    1. More compact structure, using machine pump integration, higher precision.

    2. Mechanical seal, maintenance-free, watertight, improve efficiency and more environmentally friendly.

    3. Maintenance is more convenient, only a level of impeller, a mechanical seal, a little knowledge of the pump can be replaced accessories.

    4. Strong interchangeability, replaceable constant pressure vortex pump, no need to change the interface position.

    5. Compared with the old type packing pump, the efficiency is improved by about 2%.

    6. The impeller material is alloy and ground copper, and the service life is greatly improved. The above points are incomparable to the old pump.

    7. Instantaneous use of lift up to 160m to 250m.

    application range

    Direct vortex boiler feed water pump is used for pumping clean water and liquids with physical and chemical properties similar to water. The liquid temperature shall not exceed 90%C. 1.5DB3-0.7 is often used for boilers below 0.4MPa2T/h and below 0.7MPa1T/h. 2W12-250 is widely used in shipbuilding, textile, chemical industry, metallurgy, machinery manufacturing, aquaculture, fixed, wheel mobile fire pressure stabilization, heat exchange unit, brewing, refrigeration, plumbing installation pressure test, high-rise building water tower washing, maintenance under construction, agricultural remote sprinkler irrigation and other industrial and agricultural departments. If equipped with frequency conversion device can be used as a metering pump.

    The company mainly sells diaphragm pumps. Pneumatic diaphragm pumps can not only pump flowing liquids, but also transport some media that are difficult to flow. They have the functions of submersible pumps, self-priming pumps, impurities pumps, shielded pumps, mud pumps and many characteristics of conveying machinery. The flow is spacious and the passing performance is good, allowing passage of particles up to 10 mm. When pumping mud and impurities, there is little wear on the pump; No need for irrigation and water diversion, outlet pressure 7bar The pneumatic diaphragm pump has no rotating parts or shaft seals. The medium pumped by the diaphragm and other is completely separated from the moving parts of the pump and the workpiece media, and the medium transported will not leak out. Therefore, when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety; The pneumatic pump does not require oil lubrication, and even if it is idling, it will not have any effect on the pump. This is the characteristic of this pump.
