**Applications**
1. **Petrochemical Industry:** Transfer of lubricating oil, crude oil, residual oil, heavy oil, bitumen, diesel, and gasoline.
2. **Shipbuilding Industry:** Used as cargo oil pumps, booster pumps, stripping pumps, and engine lubricating pumps for fuel, lubricating oil, waste oil, bilge sludge, and seawater.
3. **Chemical Industry:** Transfer of acids, alkalis, salt solutions, resins, glycerin, olefins, polymers, and cosmetics emulsions.
4. **Paint Industry:** Transfer of inks, paints, oil-based paints, and dopes.
5. **Food Industry:** Transfer of high-viscosity media such as alcohol, beverages, honey, syrup, toothpaste, milk, soy sauce, animal oils, vegetable oils, and chocolate.
6. **Oil Storage & Transportation:** Loading and unloading of oil products at stations, ships, and tankers.
**Key Features**
1. The inlet and outlet design ensures sufficient medium remains in the pump, allowing excellent self-suction even when the suction pipe is empty.
2. A special circular valve is used in the pump body, which opens when the outlet pressure exceeds the working pressure, allowing some fluid to return to the inlet and reducing starting torque.
3. Synchronizer gears transfer torque from the drive screw to the idler screw, ensuring no metal contact and smooth power transmission. This enhances reliability and prevents damage from dry running.
4. The meshing screws form a sealed cavity that moves axially with the rotation of the screws, delivering fluid steadily without pulsation.
5. The pump body offers multiple heating structure options to adapt to different temperatures and media conditions.
**Additional Information**
Our pumps can be customized according to specific customer needs, including horizontal/vertical mounting, explosion-proof designs, protection ratings, insulation for hazardous areas, special stainless steel for food or corrosive applications, heating chambers, safety valves, and alarm sensors.
Our twin-screw pumps and systems are ideal solutions for tanker terminals, oil production, and processing. They are widely used in industries such as petrochemical, marine, shipbuilding, food, and pharmaceutical. We provide comprehensive technical data, performance details, design options, application advantages, and more upon request.
