Two-lobe Rotary Lobe Pumps This type of rotors are superior to other rotors when tranfering material with high viscosity and large powder, especially stiff particles. Output liquid cause less pulses and components will not be destroyed. Working Principle Rotary lobe pump is a positive displacement pump, which has two rotors in the pump head. The two rotors fixed on two shafts and rotate syn-chronically in counter direction. The rotation creats vacuum volume on the inlet side. The liquid is sucked into the pump head and travels around in the chamber between the rotor and the pump head casing, and is forced out on the outlet side. Applications Rotary lobe pumps are widely used in the following industries:●Food industry: milk, yoghourt, butter, ice-cream, chocolate, jelly, jam, syrup, beer, soft drinks, fruit juice, pudding, tomato sauce, sesame, peanut butter, condiment, edible oil, cheese blocks, whey, wort, yeast,etc.●Daily chemicals: face cream, shampoo, detergent, hand sanitizer, skin gel, detergent, cosmetics, skin cream, toothpaste, hair dye, soap, shoe polish, glycerol, fatty alcohol, hair gel, etc.●Chemical industry:gasoline, diesel, kerosene, crude oil, sludge, asphalt, paint, pigment, dyes, coating material, catalyzer, leather, fat, solvents, resins, silicone oil, adhesives, latex, colloidal material, and other colloidal subst, etc.●Pharmacy industry:health care products, pharmaceutical, vaccine, biological products, syrup, slurry, protein, royal jelly, extracts, emulsions, pills slurry, fish meal, pollen, etc.Features of LGP Rotary Lobe Pumps: 1. All parts of the pump in contact with transported materials are made of Stainless Steel and meet sanitation standards. 2. Easy for cleaning. It has good CIP (clean-in-place) and SIP (steam-in-place) feature. 3. High efficiency, reliability, corrosion resistance and can transfer liquid with particles and viscoisty up to 1,000,000 cps. 4. Output flow is constant and stable. 5. All models with mechanical seal flushing. 6. Different materials for the balance mechanical seals: SiC-Tungsten Carbide, SiC-SiC, Tungsten Carbide-Tungsten Carbide.
