Product Name: Best Preice LPG Fuel Vane Pump Rotary Vane Pump Structure: Outer Slide Transmission: Belt Transmission Theory: Gas-hydraulic Hybrid Type Air Engine Type: Diesel Engine Type: Self-priming Pump With Inner Recirculation Usage: Oil, Air Pump Application: Metering Certificates: ISO9001 Fuel: Gasoline Voltage: 12V/24V/220V/380V Warranty: 1 Year Color: Customer Specifications Standard or Nonstandard: Standard Trademark: aistar Transport Package: Individual Boxed Specification: 1 pcs/ carton Origin: China Product Description Advantage:1.Durable pumps for fast and quiet operation.2.Sliding vane design provides sustained performance and trouble free operation, high reliability.3.Adjustable relief valve protects pump from excessive pressure.4.T-type strainers are available to protect pumping system from damage caused by welding slag and other matter in the piping and tanks.Maximum Operating LimitNominal FlowrateGPM80157270505LPM3005941,0221900Rated SpeedRPM640640640500ViscositySSU20,000Cp4,250Differential PressurePSI125Bar8.6Working PressurePSI175Bar12.1Temperature0F300ºC149PowerHP351025KW2.247.518.5Advantage:1.A cost effective alternative to submersible designs.2.Meeting multiple demands for LPG application.Whether a low or high flow rate with a high differential pressure, by underground and aboveground tank application3. LWB-150 pump is an idea pump for two dual hose LPG dispensers4. Continuous duty design.5. Serviceability is simple and cost effective.Technical SpecificationInlet1½"Outlet1"Speed60Hz 3450 RPM or 50Hz 2880 RPMMax.Working Pressure27.6 bar(400PSI)Max.Differential Pressure17.2bar(250PSI)Max./Min.Temperature-32ºC~107ºCPower of Motor15KwAdvantage:The pump is used for transferring LPG,especially it is high differentialpressure,low NPSH and the gas of LPG up to 50%when pumping LPG from underground tank.Technical Specificationdirection of rotationanti-clockwise facing the end of of the pump drive shaft.Max. pressure40bars at 120°Cspeed1450rpmpower380V,50Hz,4KWambient temperature20°C-+60°Cclass6connecting flangesDIN2501,PN40bearingsslip bearing at the pump end.ball bearing at the drive endlubricationThe slip bearing at the pump end lubricated by the pump liquid drive the ball bearing to self lubricate.Advantage:1.The close-coupled design is convenient to install and can save space.2.The bearings are all used the imported products with brand name of NTN or NSK3.The standard seals are all used the John Crane mechanical seals, eliminating leakage, easy maintenance4.2BV series products have the cavitation protection port.When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump.5.Aluminum bronze impeller is of high intensity and wearing well.The erosive-proof capacity of the pump can be improved by using it.If the parts where the liquid flows are made of the stainless steel,the pumps can be used under the more rigorous condition.6.The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the 2BV vacuum pump.The motors are all adopted Y2 series products.The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.(normal is B).7.2BVwater ring vacuum pump can achieve all of the PTFE flexible seal, which can greatly extend the working life in more demanding conditionsRunning smoothly, the noise can be as low as 62 db.
