C. Features
1. The inlet and outlet design ensures sufficient medium remains in the pump. Even when the suction pipe is empty, the pump still has excellent self-priming performance.
2. The pump body uses a special circular valve that opens when the outlet pressure exceeds the working pressure. This allows some fluid to return to the inlet, reducing startup torque under full pressure.
3. A synchronizer gear transfers torque from the driving screw to the driven screw, ensuring no metal contact and reliable power transmission between elements. This prevents damage during dry running.
4. The meshing screws form a sealed cavity inside the pump. As they rotate, the liquid moves axially with the cavity, delivering it steadily and continuously without pulsation.
5. The twin-screw pump comes with multiple heating structures to adapt to different media under varying temperatures.

D. Other Information
Our pumps can be customized according to customer needs: horizontal, vertical, trolley structure; explosion-proof level, protection degree, insulation level (for hazardous areas), special stainless steel for food and corrosive applications, heating chambers, safety valves, alarm sensors, etc.
Our twin-screw pumps and systems are ideal solutions for tanker terminals, oil production, and processing. They are widely used in industrial, petrochemical, marine, shipbuilding, and food and pharmaceutical industries. We can provide all relevant technical data, performance details, designs, options, principles, application advantages, and usage areas for each pump.

E. After-sales Service
Within the warranty period, we will repair or replace parts free of charge for non-artificial quality issues, excluding normal wear and tear.Horizontal Twin Screw Pump for Marine Use
