Screw Pump for Liquid (2W. W)

Screw Pump for Liquid (2W. W)
Overview
The double-entry twin-screw pump is self-designed by Shanghai Yinuo. The viscosity can be 1~3000cSt, which can be expanded to 100000cSt when reduces the pump speed. For muti-phase, the gas content shall be less than 80%, and sediment concentration shall be no more than 500g/m3.Feature
1. Low pulsation, low noise, and compact structure;
2. Heat-tracing function with heat conducting oil to ensure the transportation of high-density oil;
3. Motor drive the pump directly without any reduction gear, which is easy to maintain;
4. To meet user's request for different pressure and flow rate by changing the thread pitch of bush;
5. Double mechanical seal, forced rinsing/lubricating, and cooling system are to ensure the sealing in long working term;
6. In all working condition, the double-helix bushes design will make axial thrust spreading evenly on screw rod;
7. Shaft and bush are independent of optional material, which makes the pump suitable for different fields;
8. Bearing span is very short that is to reduce the deviation of screw roads, and ensure safety operation under high voltage, its delicate and compact inner structure contributes to its max. effciency;
9. Special design for pump inner casing gives enough space for liquid and separated path for gas during working, which makes the pump running smoothly with 80% gas in the pipe.Characteristic 1Shaft: Using the high strength stainless steelor alloy steel for the longer lifetime2Housing: Weld & cast type, many kinds of material availablefor different medium3Using circulating valveto prevent overload.4Rotary cover:separatestructure, different material for different medium.

Application
Why Yinuo
(1) For electronic products, we have automatic chip mounter (SMT) production line and high/low temp. testing equipment.
(2) For mechanical products, we have advantage on casting, machining, and welding.
(3) For calibration, we have calibration facilities approved by China government for oil, water and gas.
(4) For flowmeter, we are Top leaders in China for both of Coriolis Mass Flowmeter & PD flowmeter, which be approved the UL, CE, CCS (China) and BV certificate (France) for marine market.
(5) For pump, we combined Russian military technology with China low cost to manufacture for large capacity transportation of oil, chemical, water, and wastewater even if contain some participles and we also design and produce twin-screw pump for high pressure, high viscosity liquid with multiphase.
(6) For SCADA loading & metering/ Skid Mount System, we also have much experience in China and in Afghanistan, Angola, Equatorial Guinea, Myanmar and are trying to promote in all over the world.
