Paper Pulp Transfer Rotary Lobe Pump with High Efficiency and High Quality

Paper Pulp Transfer Rotary Lobe Pump With High Efficiency and  High QualityDifferent structure and material of mechanical seal for paper coating, can extend service life of seal.Paper making lobe pumps are widely used to transfer PAM, starch slurry, liquid rosin, rosin gum. paper slurry, dry-strength agent, wet-strength agent, sizing agent, defoaming agent, coloring starch, coating and so on.We have more than 60 domestic and foreign paper industry users, more than three thousand rotary pumps are procured for use in paper making industry. Such as UPM, ECOLAB, GAW, Stora Enso, Kemira, ASIA Symbol, Nine Dragons Paper, OJI paper, Lee & Man paper, APP paper...... Now, we have a very mature R & D technology and application technology,Lobe pump is very well used in the industry and it has gradually replaced the screw pump in many working conditions of paper making industry. Lobe pump maily used following positions.Preparation of starch glue and feeding and conveying of starch.----S.S. lobe pumpCoating preparation and coating feeding and transportation.----S.S. lobe pumpChemical unloading and chemical addition.----S.S. lobe pump  Product features:1. Gap is kept between the rotors and rotors & pump body, no friction, long using-life.  2. Simple assembling and disassembling, easy to maintenance and clean, less easily-damaged parts.  3. High efficiency and energy-saving, low failure, reliable sealing and low noise.   4. In the same type pump, different type rotor can be interchanged.5. Capable to pmp the viscous medium from 1cp to 2million cps.  6. Capable of pumping mixture of gas, fluid and solid medium.  7. Equipped with inverter, the flow can be adjusted as requirement of end-user.   8. Flange, screw or clamp connection can be selected as required.  9. Higher hygienic grade, support CIP, SIP. The surface roughness is 0.2--0.8um, got 3A, FDA certification.  10. Hygienic safety valve is built-in structure.   Structure drawing and main material      DescriptionMaterialQuantityPump cover304 /304L /316 /316L1Pump body304 /304L /316 /316L1RotorRubber /304 /304L /316 /316L2Main shaft316-316L /42CrMo1Sub-shaft316-316L /42CrMo1Mechanical seal seat304 /304L /316 /316L2Mechanical sealSIC /Tungsten carbide2O-ringFKM /FFKM/ EPDM /TFE /PTFE,etc.1Rotor lock nut304 /304L /316 /316L2Lip sealNBR /FKM3Working Principle of Lobe PumpTwin-Rotary pumps are multi-functional and bi-directional positive displacement pumps, produced with fine technology. The manufacturing engineering and precision of the pumps approach the advanced level of the world. Rotary pumps use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium.    Technical parametersTypeCapacity fortri-imepller rotor(L/r)Rotation speed(r/min)Flow(m3/h)Discharge Pressure(MPa)Standard I& O DN(mm)Enlarged I& O DN(mm)WeightBare pump(kgs)15TLS12-0.5C0.0410-7200.51.215253025TLS12-2C0.1510-72021.225404040TLS12-5C0.3210-50051.240505050TLS12-10C0.6510-500101.250658060TLS12-15C1.110-500151.2658012065TLS12-20C1.7410-500201.2658020075TLS12-30C2.610-500301.28010023080TLS12-40C3.6510-500401.2100125260100TLS12-60C5.210-500601.2125150400125TLS12-80C6.810-500801.2125150450140TLS12-120C9.810-4001201.2150200600150TLS12-150C12.810-4001501.2150200680200TLS12-200C1610-3002001.2200250780250TLS12-300C2010-3003001.2250300900300TLS12-400C3010-3004001.23003501100........................   Installation drawing and weightHorizontalTypeAAABBBCDEFMNstandard sealwater flush seal15TLS12-0.5C1401706799.541.5 Φ17209251425TLS12-2C18522010814450.561.5Φ225098618.540TLS12-5C210240114154.56071Φ285011182450TLS12-10C2462841251757182Φ385013010
