Thank you for your interest in our pumps. Below is a brief introduction of this product. Feel free to contact us for more technical details or the latest pricing information.1. Brief Introduction of Twin Screw Type Marine Cargo Pump
   This large-capacity heavy oil pump is a twin-screw type pump. It operates by using a shaft that meshes with the spiral sleeve and the pump body to create a sealed cavity. As the screw rotates, the medium is transported from the inlet to the outlet, achieving continuous and stable pumping. The twin-screw pump has two types: sealed and non-sealed. Based on the media intake direction, it can be classified into single-suction and double-suction structures. This particular model is a non-sealed twin-screw pump. One end of the active screw is driven by the prime mover, while the driven screw is powered through a synchronous gear. This design ensures no metal-to-metal contact between the screws, making the pump highly reliable even under harsh conditions.
2. Structural Characteristics of Twin Screw Type Marine Cargo Pump
   Â

   The inlet and outlet are specially designed to ensure sufficient medium remains in the pump. Even when the suction pipe is completely empty, the pump still maintains good self-priming capability. The pump body features a special circular valve that opens when the outlet pressure exceeds the working pressure, allowing some medium to return to the inlet or bypass, reducing startup torque. A synchronizer gear transfers torque from the driving screw to the driven one, ensuring no metal contact and high reliability. During operation, the meshing screws form a sealed chamber, enabling smooth and continuous liquid transfer without pulsation.
