How the LKH UltraPure Centrifugal Pump Works

Inside the pump casing, the semi-open impeller rotates along with the pump shaft. The rotation of the impeller blades convey energy to the fluid causing it to move in a circular direction. As the liquid increases in velocity, this movement is partly converted into pressure before the fluid leaves the pump through the outlet.
Pump Range
LKH UltraPure





The LKH UltraPure pump is available in eight sizes to handle capacities up to 275 m3/h and differential pressures up to 10 bar at 50 Hz.

Unique Impeller Design
2 Unique Impeller Design LKH UltraPure centrifugal pumps feature a unique semi-open impeller with a special vane design that ensures particularly low NPSHr (Net Positive Suction Head required). This helps prevent the effects of cavitation and minimises mechanical damage risk.The semi-open impeller also features balance holes, which provide high flow all around the pump, especially behind the impeller near the shaft seal.
Optimised Shaft Seal
3 External Shaft Seal
Perfect sealing and lubrication largely depends on the flatness of the seal faces. All LKH UltraPure pumps have shaft seals that are machined according to stringent requirements and meet the flatness requirement of 3 light bands* or less. The stationary seal ring is solidly affixed to the back plate, providing perfectly aligned seal surfaces even after long periods of operation and potential pressure shocks or vibration in the system.

External Shaft Seal
4 Optimised Shaft Seal

With few wear parts, the front-loaded external shaft seal is designed for high performance and low maintenance. There is no need to disconnect or remove the pump casing for inspection or maintenance, which saves time and money and minimises downtime. Only five minutes are required to replace the shaft seal.
