6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform personnel about the technical data.
6.1 Technical data
The LKH Evap pump is highly efficient and econominal centrifugal pump, which meets the requirements of sanitary and gently
product treatment and chemical resistsnce. LKH Evap is available in the following sizes LKH Evap -10, -15, -20, -25, -35, -40,
-50, -60, -70 and -75. The instruction manual is part of the delivery. Study the instructions carefully. The large pump sizes are
very heavy. Alfa Laval therefore recommends the use of a lifting crane when handling the pump.
