LSN and HYDROVAR
Operating Options
By optimizing the pump performance according to system
demand high potential of savings are achievable.
m Energy savings up to 70%.
m Increasing reliability and improved life time due to con-
trolled operating conditions avoid dry run, head losses
and cavitation.
m Reduced hydraulic forces improve bearing and mechanical
seal life time.
m Lower installation costs due to elimination of control
valves as well as panels and controllers.
m Patented microprocessor based pump controller for
variable speed operation, specifically developed for
pump operation.
m Easy start up, without programming, simplyfies installation.
m Hydrovar Smart: Hydrovar function and features without
power limitation, combination with all standard frequency
inverters possible.
