2GC type twin-screw pump
Model: 2GC4.0-26
Material: Carbon Steel
Uses: used oil, shipbuilding, power plant, food industry, etc.
 
Advantages
1, the transmission fluid smooth , pulseless , without stirring ,vibration, low noise.
2 , has a strong self-absorption properties, when multiphasetransport , gas rate is not higher than 80% , sedimentconcentration is not higher than 500g/m3.
3 , external bearing structure , using an independent lubrication,can transport a variety of non -lubricating media.
Using synchronous gear drive between the two rotors do not touch ,even if short-term idling anyway.
5 , the body with a heating jacket , you can transport all kinds ofclean or contain low viscosity or high viscosity medium small solidparticles ( particle diameter is generally less than 0.12-0.2mm).
6 , the correct choice of materials , can be transported even manycorrosive media.
7 , double -suction structure , no axial force on the rotor.
8 , shaft mechanical seal or bellows mechanical seal , with a longlife , less leakage , for a wide range of features.
Performance range
A maximum working pressure of 4.0MPa
2 , flow range 1 ~ 1000m3 / h
3, the temperature range of -20 ~ 120 ℃
4 , the viscosity of the medium 1 ~ 3000mm2 / s, lower speed canreach 106mm2 / s
Medium viscosity performance on a large twin-screw pump , the pumpdisplacement is the nominal displacement under specific conditionsthe viscosity , in order to ensure the pump to operate at highefficiency when the test is not sufficient , it is recommended toselect the following viscosities speed:
Medium viscosity cSt speed r / min
< 4001500
400 ~ 12001000
1200 - 3600750
For higher viscosity media , which should be used for speed andmotor power , please contact the manufacturer .
Applications
1 , oilas oil, gas , water, solid-phase micro- fine particles ofMultiphase Pump and oil pump.
2 , the shipbuilding industryas a marine loading pump , bilgestripping and sewage treatment , the host lubrication pumps , fuelpumps.
3 , petroleum chemical industryas a variety of resins , pigments ,waxes , paints, inks , latex , all kinds of oil , crude oil, heavyoil and other loading and transport pumps.
4 , thermal power plantsas heavy oil, oil pump, oil pump hosts .
5, the food industryas a sprinkle fine, honey , syrup , fruitjuice, animal and vegetable oils , milk, pulp oil pump. HW140-50F工业泵黄山-lng装车泵操作规程说明————螺杆泵就找杜工，专注螺杆泵15年，省心高效.—,
