pressures up to 15 bar.Benefits•Low pulsation and very gentle pumping, making the pump ideal for sensitive products.•Minimized shearing for protecting end-product quality.•Low maintenance, increased process uptime.•Maximized performance and minimized risk ofcontamination.Standard designAll media contacting steel components, like the rotor case, front cover, rotors and rotor nuts, are in W. 1.4404 (AISI 316L). The robust stainless steel gearbox provides maximum shaft rigidity and easy oil seal replacement. The gearbox design is universal which enables the flexibility of mounting pumps with the inlet and outlet ports in either a vertical or horizontal plane by changing the foot and its position.The standard Alfa Laval SX has four-lobe rotors rated to 150°C, facilitating use with CIP and SIP processes.Fully front-loading and fully interchangeable single, single flushed, and double mechanical shaft seals are available. All media contacting elastomers are controlled compression joints, the latest technology where static and dynamic elastomer seals are used to prevent leakage of pumped media to the atmosphere.The Alfa Laval SX can be supplied either as a bare shaft pump or mounted on a base plate complete with coupling, guard, gear motor and shroud for easy, plug-and-play installation. Working principleA gear train in the pump gearbox drives the rotors and provides accurate synchronization of the multi-lobe rotors. The movement of the counter-rotating rotors creates a partial vacuum that allows atmospheric pressure or other external pressures to force fluid into the pump chamber. As the rotors revolve, an expanding cavity forms, filling with fluid. As the blades disengage, each dwell forms a cavity. As the rotor blades engage, the cavity diminishes, and fluid is displaced into the outlet port.TECHNICAL DATAInside surface finish:Mech Ra ≤ 0.8Gearbox:Stianless steel Base plate:Stainless steel Coupling guard:Stainless steel Rotor:Four-lobe Product wetted elastomers:EPDM Other elastomers:FPMShaft seal:Single mechanical (R00)Rotary seal face:CarbonStationary seal face:Stainless steelMax flush pressure, single flush:0.5 bar Max flush pressure, double mechanical: 1 bar over product pressure Water consumption, flushed or double mechanical:0.5 l/min Flush connections:BSPT or NPTMedia contacting elastomersAll media contacting elastomers are controlled compression joints, the latest technology where static and dynamic elastomerseals are used to prevent pumped media leaking to atmosphere.1.Front cover compression joint2.Spline sealing cup seal3.Cup seal4.Squad ringFlows/Pressures/ConnectionsSX1/0070.07 1.54 1.8540 1.571001200SX2/0130.128 2.82 3.3840 1.5152151000SX2/0180.181 3.98 4.7850271001000SX3/0270.266 5.857.03502152151000SX3/0350.357.709.25652.571001000SX4/0630.6313.8616.6565 2.5101451000SX5/0820.8218.0421.6765 2.515215600SX5/115 1.1525.3030.3880310145600SX6/140 1.4030.8036.9980315215500SX6/190 1.9041.8050.20100410145500SX7/250 2.5055.0066.05100415215500SX7/380 3.8083.60100.40150610145500Note 1.

Authorized to carry the 3-A symbol, they are suitable for both CIP (cleaning-in-place), SIP (sterilization-in-place) and manual cleaning. LKH UltraPure pumps are also available with either a 20 Ra or 15 Ra finish, flushed seal kit and a comprehensive Q-doc documentation package to smooth the qualification and validation process.LKHThe LKH is a highly efficient and economical centrifugal pump range, which meets the requirements of sanitary processes for gentle product treatment, hygiene and chemical resistance. Its front-loaded design makes quick, effective maintenance possible, thereby contributing to more production time and low cost of ownership. Available in 13 sizes, the LKH features efficient drives which make it possible to optimize performance for the selected duty as well as comply with 3-A, CE and EHEDG requirements.LKH-75Designed for high flow rates with very gentle product treatment, the LKH-75 is ideally suited for high volume milk receiving required by the largest dairies. Like the entire LKH series, the LKH-75 features enlarged inlets combined with an advanced impeller design, resulting in unobstructed product flow and very low NPSH requirements. The pump has a capacity of up to 800 GPM and pressures of 180 feet of water and operates at a gentle 1800 RPM, and features low power consumption and noise emission levels. This translates to high flow rates withextremely gentle product treatment which are critical to maintain the taste and value drivers of high volume milk production.8LKH MultistageDesigned to 3-A standards and available in two, three or four-stage models, LKH Multistage pumps save space and energy by replacing up to three booster pumps in a line. Used primarily in high-pressure applications with low capacity, they deliver boost pressures up to 900 feet (390 PSI). This makes them suitable for, but not limited to, many types of filtration applications.LKH-PF High PressurePumps in the LKH-PF High Pressure series feature a reinforced pump casing and backplate, as well as high pressure internal seals and multiple heavy-duty studs. This enables them to handle inlet pressures as high as 600 PSI, making them ideal for the most demanding filtration applications. Their seals can be removed in a matter of seconds, without removal of the back plate.LKH-90The LKH-90 extends the LKH range flow rate to 2,200 GPM, making it an ideal solution for today’s high volume applications. Specifically, the LKH-90 has proven to be the pump of choice for filtration system builders. It utilizes the same front-loading seal as the LKH-75 and is available in a variety of connection types.Only one size of shaft seal is required for all LKH standard models (LKH 5–60) and SolidC (SolidC 1–4), which makes keeping the right parts in inventory simple and inexpensive.

阿尔法拉夫双扁平泵介绍说明书
pulse-free, the pump provides smooth and gentle operation,making it an excellent choice for handling sensitive products.Two-in-one operation provides easy handling of process media of varying viscosities as well as CIP fluids. This simplifies piping and pump control, cutting costs and minimizing contamination risks.Superior suction performance with excellent lift capability and low NPSHr provides installation flexibility and increases product recovery.The Alfa Laval Twin Screw Pump is available in twelve models based on four frame sizes. Each frame size is available with three different screw profiles for varying pressure, flow and solids-handling capabilities.Benefits•Greater process flexibility.•Ease of service, increased process uptime.•Robust reliable design, reducing cost of ownership andincreasing process uptime.•Improved product quality.•Exceptional hygiene and cleanability.Standard designAll media contacting steel components, like pump casing, front cover and feed screws are in W. 1.4404 (AISI 316L). Furthermore, the pump casing is diffusion hardened. A stainless steel gearbox, end cover and foot ensure increased life and assist in washdown.The gearbox is designed with the timing gears located between the bearing sets, rather than external to them. This allows the bearing location to be optimized in order to provide maximum support to the shaft assembly, thereby providing a robust rigid design. The internal gearcase design optimizes oil circulation to both sets of bearings and the timing gears with an oil sump design. This improves the lubrication effect on both bearings and timing gears, minimizing the energy produced due to friction and thereby reducing heat generation within the pump gearbox.The front-loading, self-setting cartridge design makes it easy to replace the shaft seal while the pump is in place. Single, single flush and double mechanical cartridge seals are available. All options are fully front-loading and interchangeable.The Alfa Laval Twin Screw Pump can be supplied either as a bare shaft pump or mounted on a base plate complete with coupling, guard, shroud and a direct coupled motor or a gear motor for easy, plug-and-play installation.Working principleThe Alfa Laval Twin Screw Pump is a positive displacement pump. As the pump rotates, the intermeshing of the two contra-rotating screws, along with the pump casing, form volumetric chambers. These chambers fill with the pumped fluid and move the fluid axially from the suction side of the pump to the higher pressure discharge side.TECHNICAL DATAScrews, front cover, seal housing:W. 1.4404 (316L)Inside surface finish:Mech Ra ≤ 0.8Gear box:Stainless steel Base plate:Stainless steel Coupling guard:Stainless steel Product wetted elastomers:EPDM Other elastomers:FPMShaft seal:Single flush Rotary seal face:Silicon Carbide Stationary seal face:Silicon CarbideMax. flush pressure, single flush:0.5 bar Max. flush pressure, double mechanical:16 bar (max. 6 bar over product pressure)Water consumption, single flush and double mechanical:0.5 l/min.Flush connections, OS12-36:G 1/4" or NPT 1/4"Flush connections, OS42-46:G 1/2" or NPT 1/2"Max. discharge pressure:16 barMax.
