Alfa Laval LKH Multistage Centrifugal Pump

Alfa Laval LKH Multistage Centrifugal Pump

The multistage centrifugal pump is a high-efficiency solution engineered for demanding hygienic environments where precision and reliability are non-negotiable. Designed to replace multiple booster pumps in a single line, this unit excels in high-pressure, low-capacity applications, significantly reducing your physical footprint and energy overhead. Whether you are managing complex filtration or high-head transfers, this stainless steel sanitary pump provides the robust performance required for sensitive processing tasks. Its advanced impeller design and tight internal tolerances minimize recirculation, ensuring every watt of energy is used effectively to move your product safely through the line.

How does a multistage centrifugal pump improve process efficiency?

The LKH Multistage series is specifically designed to handle extreme pressure requirements that would typically require several individual pumps installed in series. By utilizing up to four stages within a single unit, this pump can withstand system pressures up to 40 bar and deliver differential pressures up to 19 bar at 50 Hz. This consolidated design not only saves valuable floor space but also reduces the total cost of ownership by lowering energy consumption and simplifying the spare parts inventory needed for your facility.

Hygienic design for filtration and sensitive media

Construction materials are critical in sanitary environments, which is why all media-contacting steel components, including the pump casing, impellers, and backplate, are manufactured from W. 1.4404 (AISI 316L) stainless steel. The unit is designed for full CIP cleanability, ensuring that even the most stringent hygiene standards are met. The balanced shaft seal design is a key safety feature, minimizing the risk of seal opening during unforeseen pressure shocks, which protects both the equipment and the integrity of your product.

Simplified maintenance with front-loading seals

To maximize uptime, these pumps feature a front-loading shaft seal design. This allows maintenance teams to replace the seal in just a few minutes without extensive disassembly of the unit. For the most demanding high-pressure scenarios, P-models are available with reinforced backplates and special motor bearings, ensuring the pump remains stable and performs reliably under continuous heavy-duty cycles.

Yes, because it is available in two-, three-, or four-stage models, it can deliver high differential pressures (up to 19 bar) that typically require multiple pumps in series. This consolidation saves installation space and reduces total energy consumption across your process line.

Standard models handle significant inlet pressures, but special P-model versions with reinforced backplates are designed for inlet pressures up to 30 bar or higher depending on temperature. The overall system is engineered to withstand total pressures up to 40 bar.

Maintenance is fast and inexpensive due to the front-loading shaft seal design, which allows for replacement in just a few minutes. You can also specify a flushed shaft seal option for applications involving high temperatures or media that could crystallize.
