Huanggong Stainless Steel Fuel Oil Two Spindle Screw Pump

A. Application Area
Twin screw pumps are ideal for use as Fuel Oil pumps, Diesel Oil pumps, Heavy Oil Transfer pumps, Lube Oil pumps, Lubricating Oil pumps, or Chemical pumps. They can transfer various non-solid-containing fluid media or extremely high-viscosity media. These pumps offer wide availability and high reliability for both lubricating and non-lubricating media, as well as corrosive media or gas-liquid mixtures.

B. Application Areas
1. Petrochemical Industry: Transfer pump for various lubricating oil, crude oil, residual oil, heavy oil, bitumen, diesel oil, gasoline, etc.
2. Shipbuilding Industry: Transfer pump, cargo oil pump, booster pump, stripping pump, and engine lubricating pump for various fuel oil, lubricating oil, waste oil, bilge sludge, and sea water, etc.
3. Chemical Industry: Transfer pump for various acid, alkali, salt solution, resin, glycerin, olefin, polymers, and various cosmetics emulsions.
4. Paint Industry: Transfer pump for various printing ink, paint, oil paint, dope, etc.
5. Food Industry: Transfer pump for various high-viscosity medium like alcohol, beverage, honey, sugar juice, toothpaste, milk, soy sauce, animal oil, vegetable, and chocolate, etc.
6. Storage & Transfer Industry: Loading and unloading oil goods for oil stations, ships, and tankers.

C. Key Features
1. The inlet-outlet design ensures sufficient medium is retained in the pump. Even when the suction pipe is completely drained, the pump still has excellent self-suction performance.

2. The pump body uses a special circular valve that opens when the outlet pressure exceeds the working pressure. This allows some medium to return to the inlet or be redirected, enabling the pump to start under full pressure conditions, significantly reducing torque.

3. Synchronizer gears transfer torque from the drive screw to the idler screw, ensuring no metal contact and smooth power transmission between components. This increases reliability for all types of media and protects against damage during dry running.

4. The meshing screws create sealed cavities within the pump body. As the screws rotate, the liquid moves axially with the cavity, delivering it steadily and continuously to the outlet. Since the cavity volume remains constant, there is no pulsation during operation.

5. The twin-screw pump body offers multiple heating structure options to adapt to different media at varying temperatures.

D. Additional Information
Our pumps can be customized based on customer needs: Horizontal, Vertical, Trolley structure; Explosion-proof level, Protection rating, insulation level (for hazardous areas), special stainless steel (for food industry, corrosive liquids, etc.), heating chamber, safety valve, alarm sensor, etc.
Our pumps (mainly twin-screw pumps) and systems are ideal solutions for tanker terminals, oil production, and processing. They are widely used in industrial, petrochemical, marine, shipbuilding, food, and pharmaceutical industries. You can request technical data, performance details, designs, options, principles, application advantages, and more for each pump type.
