Screw Pump

G type screw pump is a closed screw pump with internal meshing, which is a rotor type positive displacement pump. The screw pump has strong adaptability to the medium. stable flow, small pressure pulsation, good suction performance, and can transport all kinds of flow able media. ln addition, it can also transport highly viscous media, media containing hard suspended particles on solid particles, and media containing fibers. It has good adjustment performance, wide range and high efficiency. Therefore it is used in environmental protection, petroleum, medicine, and daily chemicals, food, brewing, construction, mining, chemistry, printing, paper making, power plants, boilers and other industries are widely used.

STRUCTURE

Screw Pump Composition

DETAILS

Pump body castings
Self-produced molds, thickened castings, Optional cast iron, stainless steel material Precise control of installation dimensions, complete drawings
Stator Optional
Standard nitrile rubber or natural rubber stator, The following materials are available: Nitrile rubber Natural rubber stator Silicone stator Viton stator White nitrile rubber stator
Copper Motor
Full copper wire configuration, stable bass operation, Corresponding to different working conditions, it can be replaced with different motor adjustments such as explosion-proof, frequency conversion, stepless speed regulation, gear reduction, etc.
Stainless Steel Screw Shaft
The screw shaft is 304 stainless steel, Does not rust and prolongs service life.

WORKING CONDITIONS

Precautions for use:

1. The direction must be determined before turning on the machine, and no reversal is allowed: 2. It is strictly forbidden to run dry without medium to avoid damage to the stator; 3. The pump that is newly installed or stopped for several days cannot be started immediately. You should inject a proper amount of oil or soapy water into the pump body, and then use a pipe wrench for a few turns before starting; 4. After transporting high-viscosity or particle-containing and corrosive media, water or solvent should be used for flushing to prevent blockage, so as to avoid difficulty in starting next time; 5. In winter, the effusion should be removed to prevent freezing and cracking; 6. Lubricating oil should be added to the bearing seat regularly during use, and if there is leakage at the shaft end, the oil seal should be treated or replaced in time; 7. If an abnormal situation is found during operation, stop immediately to check the cause and eliminate the fault.
