W Type Single Stage Vortex Pump
DARUI Electric recommends:
W Type Single Stage Vortex Pumpis used for pumping clean water and liquids with physical and chemical properties similar to water, the liquid temperature should not exceed 60℃, commonly used in boiler feed water supporting, used in shipbuilding, textile, chemical, metallurgy, machinery manufacturing, aquaculture, fixed fire protection pressure stabilization, heat exchange units, brewing, refrigeration, water heating installation pressure testing, high-rise building water tower flushing, construction maintenance, agricultural remote sprinkler irrigation and other industrial and agricultural sectors have extensive use. If equipped with frequency conversion device, it can be used as metering pump.
1. More compact structure, adopting integrated pump and motor, higher precision.
2. Adopting mechanical seal, maintenance-free, drip-free, improving efficiency and more environmentally friendly.
3. More convenient maintenance, only one stage impeller, one mechanical seal, those with a little knowledge of pumps can replace parts.
4. Strong interchangeability, can replace 1.5DB-0.7 pump without changing interface position.
5. Compared with the old type of material pump, efficiency is improved by about 20%.
6. The impeller material adopts alloy wear-resistant copper, greatly improving service life.
7. Instantaneous head can be above 160m.
The above points are incomparable to the old type pump.
II. Structure Description of W Type Single Stage Direct-connected Vortex Pump
This pump adopts direct connection structure of pump and motor, its water inlet is horizontal, and the outlet is vertically upward. Viewed from the pump end, the pump rotates counterclockwise. The impeller can slide freely on the cantilever shaft, and during operation, it can automatically adjust the clearance on both sides of the impeller. The outer partition can be removed together with the impeller by using the two screw holes on the impeller.
The inner partition adopts 9-4 aluminum iron bronze, the shaft adopts stainless steel, and the packing adopts flexible graphite sealing material.
