Trademark: HUANGGONG
Transport Package: Wooden Crate
Specification: 2HM280, 560, 800, 1400, 2500, 4200, 7000, 18000
Origin: China
HS Code: 8413
Product Description
Certification: ISO9001:2000, CE, CCS, BV, NK, KR, ABS, RINA, GL, etc.
Application Range
The twin screw pump is an ideal choice for use as a Fuel Oil Pump, Diesel Oil Pump, Heavy Oil Transfer Pump, Lube Oil Pump, or Chemical Pump. These pumps are designed to handle various non-solid containing fluids or high-viscosity media. They are reliable for both lubricating and non-lubricating substances, as well as corrosive materials and gas-liquid mixtures.
Medium Types
- Various lubricating oils and fuel oils
Construction Options
- Horizontal, vertical, portable structures
- Heating chamber available
Safety Features
- Explosion-proof design
- Water protection
- Safety valve and alarm sensor
Industries of Use
1. Petrochemical Industry: Transfer of lubricating oil, crude oil, heavy oil, bitumen, diesel, gasoline, etc.
2. Shipbuilding Industry: Cargo oil pumps, booster pumps, stripping pumps, engine lubricating pumps for fuel, lubricant, waste oil, bilge sludge, and seawater.
3. Chemical Industry: Transfer of acids, alkalis, salt solutions, resins, glycerin, olefins, polymers, and cosmetic emulsions.
4. Paint Industry: Transfer of inks, paints, oil-based paints, and dyes.
5. Food Industry: Handling of high-viscosity media such as alcohol, beverages, honey, sugar juice, toothpaste, milk, soy sauce, animal oil, vegetable oil, and chocolate.
6. Oil Transportation: Loading and unloading of oil products at stations, ships, and tankers.
Key Features
1. Unique inlet-outlet design ensures sufficient medium remains in the pump, even when suction pipes are fully emptied, providing excellent self-priming performance.
2. Special circular valve in the pump body opens when outlet pressure exceeds working pressure, allowing some fluid to return to the inlet, reducing starting torque and enabling operation under full pressure.
3. Synchronizer gear transfers torque from the drive screw to the idler screw, eliminating metal contact and ensuring smooth power transmission. This enhances reliability and prevents damage from dry running.
4. Sealed cavities formed by meshing screws allow for continuous and steady liquid transfer without pulsation due to constant cavity volume.
5. Multiple heating structure options available to suit different operating temperatures and media types.
Customization Options
Our pumps can be tailored to meet specific customer requirements, including: - Horizontal or vertical mounting - Explosion-proof levels and IP ratings - Insulation for hazardous areas - Special Stainless Steel for food or corrosive applications - Heating chambers, safety valves, and alarm sensors
Our twin-screw pumps are ideal for use in oil terminals, production facilities, and industrial sectors like petrochemicals, marine, food, and pharmaceuticals. We provide comprehensive technical data, performance details, and application information upon request.
