Alfa Laval LKH UltraPure Centrifugal pumps Introduction The Alfa Laval LKH UltraPure Centrifugal Pump is designed for use in high-purity applications where high efficiency, exceptional cleanability, contamination safety, robust design and low maintenance are of paramount importance. With verified cleanability, these pumps provide unobstructed product flow, very low NPSH requirements and excellent hydraulic efficiency. Precision-engineered, the LKH UltraPure pump delivers greater energy efficiency than similar pumps. Its optimized design, premium motor, tight tolerances and advanced impeller design minimize recirculation and reduce energy consumption. Applications The Alfa Laval LKH UltraPure pump is designed to meet the stringent demands and regulations of high-purity applications across the biotechnology and pharmaceutical industries which require equipment with the highest material integrity. All pumps are delivered with a complete Alfa Laval Q-doc package. Q-doc provides easier validation, proof of origin and compliance for inspection according to Good Manufacturing Practice (GMP) and ASME BPE requirements. The LKH UltraPure pump is available in eight sizes to handle capacities up to 1300 USGPM and differential pressures up to 500 feet at 60 Hz. Benefits • Energy efficient: superior efficiency resulting in reduced energy consumption and CO2 footprint. • Maximized uptime and reduced maintenance costs: robust mechanical design and ease of maintenance with modular front-loading seals. • Low contamination risk: comes with full material traceability and USP Class VI elastomers to reduce risk of process contamination from extractables. • Smooth qualification, validation and process control: material traceability, and pump supplied with the Alfa Laval Q-doc package in line with Good Documentation Practice (GDP). Standard design All media contacting steel components like pump casing, impeller, impeller nut and backplate are in AISI 316L with material traceability 3.1 according to EN 10204. Product wetted elastomers are specified to USP Class VI, 249.8°F, Chapter 88 and Chapter 87. Four adjustable stainless steel legs support the complete unit. A compression coupling securely attaches the stub shaft to the motor shaft with precision alignment, and the semi-open impeller with a special vane design ensures efficient and gentle handling of the product as it moves through the pump. As standard, the LKH UltraPure pump is equipped with a single mechanical shaft seal but is also available with a double mechanical shaft seal. The front-loading shaft seal, with the spring and washers mounted on the atmospheric side, makes maintenance fast, easy and inexpensive. It takes just a few minutes to replace the shaft seal. In addition, the balanced 55
