Huanggong Stainless Steel Fuel Oil Two Spindle Screw Pump

A. Application Field
Twin screw pumps are an excellent choice for use as Fuel Oil pumps, Diesel Oil pumps, Heavy Oil Transfer pumps, Lube Oil pumps, Lubricating Oil pumps, or Chemical pumps.

Twin-screw pumps can transfer various non-solid containing fluid media or extremely high viscosity media. They offer wide availability and high reliability for both lubricating and non-lubricating media, as well as for corrosive media or gas-liquid mixtures.

B. Application Fields
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 oils, lubricating oils, waste oils, bilge sludge, and seawater, etc.
3. Chemical Industry: Transfer pump for various acid, alkali, salt solutions, resins, glycerin, olefins, polymers, and various cosmetics emulsions.
4. Paint Industry: Transfer pump for various printing ink, paint, oil paint, and dopes.
5. Food Industry: Transfer pump for various high-viscosity media such as alcohol, beverages, honey, sugar juice, toothpaste, milk, soy sauce, animal oil, vegetable oil, and chocolate, etc.
6. Storage & Transportation Industry: Loading and unloading of oil goods at oil stations, ships, and tankers.

C. Features
1. The inlet-outlet design is specially engineered to ensure sufficient medium remains in the pump. Even when the medium in the suction pipe is completely discharged, 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 medium to return to the pump inlet or be stored through this valve. As a result, the pump can start under full pressure, significantly reducing the torque required.

3. A synchronizer gear transfers torque from the driving screw to the idler screw, ensuring no metal contact and efficient power transmission between the elements. This ensures high reliability for any medium and prevents damage due to dry running in a short time.

4. When operating, the meshing screws form a sealed cavity in the pump body. As the screws rotate, the liquid in the sealed cavity moves axially with the cavity and is continuously transferred to the pump outlet. Since the capacity of the sealed cavity does not change during operation, there is no pulsation when the pump delivers liquid.

5. The twin screw pump body offers several different heating structures for selection, adapting to different media under varying temperatures.

D. Additional Information
