Why Choose the LKH Evap Centrifugal Pump for Evaporation?

The LKH Evap centrifugal pump is precision-engineered to deliver greater energy efficiency than standard models. Its optimized design features tight tolerances and a premium motor that work in tandem to lower the total cost of ownership. By reducing the CO2 footprint and energy usage, it supports sustainable manufacturing goals without compromising on powerful hydraulic performance. The inclusion of a tailored vacuum curve package allows engineers to integrate the pump into complex evaporation systems with complete confidence in its performance parameters.

High Solids Handling with ClearFlow Impeller

One of the primary challenges in evaporation is product buildup. This pump addresses that problem with the optional ClearFlow scraper impeller. This specialized design is intended for high solids applications where a hard layer of product might otherwise form between the impeller and the backplate. By preventing this buildup, the pump prolongs production time between cleaning cycles, directly increasing plant uptime. The semi-open impeller further ensures gentle product handling, maintaining the integrity of sensitive media during transfer.

Hygienic Design and Maintenance Efficiency

Constructed with W. 1.4404 (AISI 316L) stainless steel for all media-contacting parts, the pump meets the most stringent hygienic standards. Maintenance is streamlined through a front-loading shaft seal design. Because the spring and washers are mounted on the atmospheric side, technicians can replace the seal in just a few minutes without complex teardowns. The balanced seal design also protects the unit against unforeseen pressure shocks, ensuring a robust mechanical life in rigorous industrial environments.
