LKH UltraPure

Product Description

Alfa LKH UltraPure pharmaceutical pumps (certified to EHEDG) use a combination of optimised inlets and advanced impeller design to give unobstructed product flow, very low NPSH requirements and excellent hydraulic efficiency to keep your process running smoothly. They are designed for CIP and available in capacities of up to 500 m3/h and pressures of up to 190 m (19 bar).

Highly efficient and economical centrifugal pump that meets the requirements of hygienic processes

  • Low contamination risk – hygienic design with pharma-grade SiC+ seals, pre-defined compression elastomers and low-delta ferrite impeller
  • Maximized uptime and reduced maintenance costs – robust mechanical design and ease of maintenance with modular front-loading seals
  • Increased yield – comes with full material traceability and USP Class VI elastomers to reduce risk of process contamination from extractables
  • Energy and cleaning efficient – precise hydraulic design energy costs and CO2/waste chemical emissions to boost yields and process sustainability
  • Smooth qualification, validation and process control – material traceability, and pump supplied with Alfa Laval’s Q-Doc package in line with GDP

The vane design of the semi-open impeller ensures a low Net Positive Suction Head required and prevents the effects of cavitation. The impeller balance holes help circulate the process fluid in the shaft seal area reducing axial force and wear on the seal and motor bearings. The high flow around the pump, especially behind the impeller near the shaft seal, makes cleaning easy and enhances the lubrication/ cooling of the seal to prolong life.

It is also available with a wide range of options for:  

  • Shaft seals 
  • Flushing arrangements 
  • Elastomers 
  • Surface finishes 
  • Drain options 
  • Passivation 
  • Hydrostatic testing 

How it works

The LKH UltraPure centrifugal pump consists of a motor, impeller, pump casing, back plate, mechanical seal, legs, pump shaft/connections and adaptor. We use the same shaft seal for all UltraPure centrifugal pumps, regardless of size or model. This standardization reduces inventory and makes wear parts replacement quick and easy.

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

All LKH UltraPure pump shaft seals are machined to stringent requirements and meet the flatness requirement of 3 light bands* or less. The stationary seal ring is fixed to the back plate providing perfectly aligned seal surfaces even after long periods of operation/vibration and can withstand potential pressure shocks.

The balanced design and use of spring force contribute to pressure equalization within the shaft seal area. This minimizes the risk of opening during unforeseen events, such as pressure shock.
