Product Description

>>>The advantage of the twin-screw pump
1. Transporting the liquid smoothly without any disturbing and pulsation, no impulse, with less vibration and low noise.
2. It has strong selr-suction performance, when multiphase mixed transporting, the gas content can not over 80%, and the san content can not over 500G/M3.
3. Outboard bearing structure which qdopt independently lubricate, so aoo kinds of nonlubricate medium can be transported.
4. It adopts synchronous gear drinving, between the two totors there is no touch at all, ecen though idling for short term is no problem.
5. The pump body has heating jacket, so it can transport all kinds of clean or low viscosity or high viscosity mediuum which contain the particulate solids. (the diameter of the particulate is usually less than 0.12-0.2mm)
6. If selecting the material correctly, some corrosive medium can be transported.
7. Double-suction structure, and there is no axial force on the rotor.
8. The shaft ends adopt mechanical seal or corrugated pipe mechanical seal, it has the characteristic of long-life, less leak, wide scope of application.

>>>Performance scope
1. The highest pressure 4.0MPa
2. Capacity range 1~1000m3/h
3. Temperature range -20~120 Deg C.
4. Thee ciscosity of the medium 1~3000mm2/s, when lower the speed of the rotation it can be up to 106mm2/s
