Marine 2hm Two Spindle Screw Pump with Ex-Proof Motor

Here is a rewritten and improved version of the provided content in English, ensuring it's more natural, well-structured, and exceeds 500 characters: --- A. Application Range
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 various non-solid fluid media or extremely high viscosity fluids. These pumps offer wide availability and high reliability for both lubricating and non-lubricating media, as well as for corrosive substances and gas-liquid mixtures. Medium: Various lubricating oils and fuel oils.

Certificate: ISO9001:2000, CE, CCS, BV, NK, KR, ABS, RINA, GL, etc.
Construction: Horizontal, vertical, portable structure, heating chamber.
Safety: Explosion-proof, water-proof, safety valve, alarm sensor.

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

C. Key Features
1. The inlet and outlet design ensures sufficient medium remains in the pump, even when the suction pipe is empty, providing excellent self-priming performance.
2. The pump body uses a special circular valve that opens when outlet pressure exceeds working pressure, allowing some medium to return to the inlet, reducing starting torque.
3. Synchronizer gears transfer torque from the driving to the driven screw, eliminating metal contact and ensuring reliable operation for any medium.
4. The meshing screws form sealed cavities, enabling smooth and continuous liquid transfer without pulsation.
5. Multiple heating structures are available to suit different media under varying temperatures.
