Alfa Laval LKH Range
Alfa Laval Centrifugal Pump LKH
Alfa Laval’s centrifugal pumps are built to perform in all areas – from process quality to overall energy efficiency. In addition to gentle product handling and a wide range of hygienic features, they provide a long and trouble-free service life that ensures low cost of ownership. The Alfa Laval centrifugal pump LKH series can be divided into two categories, premium and standard-duty. The first category comprises the various LKH series. It handle even specialized needs such as multistage, high-pressure, self-priming and high-purity applications. The second focuses on cost efficiency and includes the value-optimized SolidC pump series.
Gentle product treatment
The centrifugal pumps are renowned for their ability to move products gently and efficiently. The integrity of your product is assured, regardless whether you choose a premium or standard-duty model.
Advanced hygienic design
With emphasis on features such as optimized internal geometry and profiled o-rings, the centrifugal pumps are suitable for Cleaning In Place (CIP) and offer exceptional levels of hygiene. All have been tested in accordance with EHEDG requirements and many are authorized to carry the 3A symbol.
Advanced seal design
The Alfa Laval centrifugal pump LKH premium pumps (models 5-60) and the SolidC standard-duty pumps share the same mechanical shaft seal. This implifies maintenance and spare parts inventory. Combined with the quick and easy front-loading design, this reduces maintenance costs, increases uptime and reduces the cost of ownership.
Easy seal conversion
The external design of thecentrifugal pumps, as well as the seal’s construction, is designed to make seal conversion as fast and as simple as possible. The premium LKH pumps can be converted from single to flushed or double mechanical seals, while the standard-duty SolidC pumps can be converted from single to flushed shaft seals.
The centrifugal pump impellers are computer designed and hydraulically balanced for optimum performance. Both the impellers and their retaining screws (optional) are smooth, which keeps them from accumulating product and makes cleaning more effective.
The centrifugal pumps consume less power and exhibit low noise levels. In addition, they minimize the risk of cavitation thanks to low NPSH requirements.
Quiet but rugged, Alfa Laval’s LKH series of centrifugal pumps are the ultimate solution for gentle and efficient product handling. Through a combination of enlarged inlets and advanced impeller design, they offer an unobstructed product flow and very low NPSH requirements.
LKH pumps are designed for Cleaning In Place (CIP). Polished models are USDA approved and exceed 3A standards, so you can always be sure of the greatest possible hygiene. LKH pumps are available in capacities of up to 440 m³/h and pressures of up to 190 m (19 bar). Also different versions are available for specific applications.
LKH-UltraPure pumps are high-purity models that meet specifications for water-for-injection (WFI) and other demanding applications. Authorized to carry the 3A symbol, they are suitable for both CIP and Sterilization In Place (SIP), as well as manual cleaning. LKH-UltraPure pumps are also available with a 0.5 μm (150 grit) finish, 3.1 certification and a flushed seal kit. For all the options and features download the datasheet. For use and maintenance download the instruction manual.
Pumps in the LKHP-High Pressure series feature a reinforced pump casing and back plate, as well as high pressure internal seals and multiple heavy-duty studs. This lets them handle inlet pressures as high as 40 bar (600 PSI), making them ideal for nanofiltration and reverse osmosis filtration. Their seals can be removed in a matter of seconds, without removal of the back plate. For all the features of the high pressure pump download the datasheet. For use and maintenance download the instruction manual.
Alfa Laval centrifugal pump LKH Multistage
Designed to 3A 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 withstand system pressures up to 40 bar (600 PSI) and deliver boost pressures up to 19 bar (275 Psi). This makes them suitable for both reverse osmosis and ultra filtration. For the options, values and features of the multistage please download the datasheet or manual for use and maintenance.
Based on the LKH range, the LKH Evap is a tailored evaporator pump supported by strong and extensive documentation, including a comprehensive vacuum curve package. It features a special scraper impeller ClearFlow that solves the product build-up problem in high solids applications, which considerably can prolong production time between cleaning. To see these curves, options and features download the datasheet. For maintenance and use of the LKH Evap please download the instruction manual.
Engineered for use in potentially explosive environments, the LKHex is available in nine sizes and conforms to the provisions of ATEX directive 94/9/EC Group II, Categories 2 and 3. To see all the sizes and options download the datasheet or instruction manual for use and maintenance.
