The double-entry twin-screw pump is self-designed by, with multiple independent intellectual properties. The pumps have been sold to Russia, United States, etc. The pump is widely used in petroleum, chemical, shipbuilding, food and other industries. It is used to transport medium clean or with including medium of low/high/sharply changing viscosity, such as crude oil, heavy oil, fuel oil, diesel oil, coal tar, lubricating oil, sea water, different acid/alkali, vegetable oil, fruit juice etc. The viscosity can be *****0cSt, which can be expanded to ******0cSt while reducing the pump speed. For multi-phase, the gas content shall be less than *0%, and sediment concentration shall be no more than **0g/m3.

Features
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 users 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 make axial thrust spreading evenly on screw rod;
7. Shaft and bush are independent of optional material, which make the pump suitable different fields;
8. Bearing span is very short that is to reduce the deviation of screw rods, and ensure safety operation under high voltage; its delicate and compact inner structure contributes to its maximum efficiency;
9. Synchronous gear movement transfer the moment of torque from power screw to idler screw without any force transmission or metal-touch between medium units, which ensures the bushes reliability for long term using;
*0. Special design for pump inner casing enough space for liquid and separate path for gas during working which makes the pump run smoothly with *0% gas in the pipe.
Working conditions
Flow range: *****0m3/h
Pressure range: **6.4MPa (customized for higher)
Suction height: 8m
Pump efficiency can be up to *0%
