Marine Stainless Steel Twin Screw Pump for Chemical Tanker

Certification: ISO9001:2000, CE, CCS, BV, NK, KR, ABS, RINA, GL, etc.


A. Application Scope
Twin screw pumps are ideal for use as Fuel Oil Pumps, Diesel Oil Pumps, Heavy Oil Transfer Pumps, Lubricating Oil Pumps, or Chemical Pumps. They can handle a wide range of non-solid-containing fluids and high-viscosity media, offering reliable performance for both lubricating and non-lubricating substances, as well as corrosive or gas-liquid mixtures.


Medium: Various types of lubricants and fuels.
Construction: Horizontal, vertical, portable, with heating chamber options.
Safety Features: Explosion-proof, water-resistant, equipped with safety valves and alarm sensors.


B. Application Fields
1. Petrochemical Industry: For transferring various oils including crude oil, residual oil, heavy oil, bitumen, diesel, and gasoline.
2. Shipbuilding Industry: Used in cargo oil transfer, booster pumps, stripping pumps, and engine lubrication systems for fuel, lubricants, waste oil, bilge sludge, and seawater.
3. Chemical Industry: Suitable for acid, alkali, salt solutions, resins, glycerin, olefins, polymers, and cosmetic emulsions.
4. Paint Industry: Ideal for printing inks, paints, oil-based coatings, and dyes.
5. Food Industry: Efficient for high-viscosity liquids such as alcohol, beverages, honey, syrup, toothpaste, milk, soy sauce, animal and vegetable oils, and chocolate.
6. Oil Transportation: Used for loading and unloading at oil stations, ships, and tankers.


C. Key Features
1. The inlet and outlet design ensures sufficient medium is retained in the pump, allowing excellent self-priming even when the suction line is completely empty.
2. The pump body uses a special circular valve that opens when the outlet pressure exceeds the working pressure, allowing some fluid to return to the inlet, reducing starting torque and enabling operation under full pressure.
3. Synchronizer gears transfer torque from the driving to the idler screw, ensuring no metal contact and reliable power transmission, protecting the pump from damage during dry running.
4. The meshing screws create a sealed cavity that moves axially as the screws rotate, delivering fluid smoothly and continuously without pulsation due to constant cavity volume.
5. The pump offers multiple heating options to suit different operating temperatures and media conditions.
