Alfa Laval LKH70 Centrifugal pump

• Transferring liquid food products such as milk, juices, and sauces within processing lines.
• Circulating cleaning-in-place (CIP) solutions in hygienic process systems.
• Handling pharmaceutical and cosmetic liquids requiring gentle and sanitary pumping.
• Moving brewing and beverage ingredients like wort, beer, and soft drinks.
• General liquid transfer in hygienic industrial environments.

Typical capacity

For this class of centrifugal pump, capacities typically range from 50 to 200 cubic metres per hour, depending on head and specific model configuration.

Power supply

Units of this type commonly operate on a 3-phase electrical supply, typically 400V, 50Hz, with motor power for an LKH70 often around 18.5kW to 22kW.

Materials of construction

Wetted parts are typically manufactured from AISI 316L stainless steel for hygiene and corrosion resistance.

Connections

Commonly features hygienic connections such as DIN, SMS, or Clamp, with sizes typically ranging from DN65 to DN100.

Seal type
