Product Details

WaCS  variable  speed  pump  controllers  are  the  ideal  solution  for  automatic  on-demand  water  supply  in multiple  outlet  applications.  Working  on  the  inverter  principle  pump  motor  speed  is  varied  with  demand thus  regulating  pump  output  to  a  preset  outlet  pressure.  This  provides  the  following  operational benefits:-

  • Constant  outlet  pressure  up  to  the  pump’s  maximum  capacity  providing  consistent,  even  supply .
  •  Up  to  50%  reduced  energy  consumption  as  pump  output  is  matched  to  site  demand.
  •  Silent  operation  without  the  start  and  stop  pressure  shocks  of  fixed  speed  systems.
  •  Elimination  of  pressure  vessels.
  •  Eliminates  starting  current  peaks.

The  revolutionary  WaCS  controller  is  a  technology  leading  control  unit  specially  developed  for  all  small scale  water supply  applications. It  is  installed  in-line  on the  pump outlet, an in-built  pressure sensor regulating  the  inverter  which  provides  variable  frequency  power  to  the  pump  motor .  Various  models are
available  for  a  wide  variety  of  pump  applications,  all  offering  the  following  advantages  and  features:-

  • Simple  to  install  and  can  be  used  for  most  types  of  pumps.
  •  Adjustable  for  outlet  pressure  and  motor  current.
  •  Flow  switch  provided  for  run  dry  protection.
  •  In-built  protection  for  high  and  low  voltage,  motor overload and  phase  failure  (three  phase  input
    supply).
  •  Provides  for  economical  installations  as  piping  is  simplified  and  requirement  for  switches,  control
    panels  and  pressure  tanks  is  eliminated.

Variable  speed  is  the  modern  way  to  optimise  automatic  on-demand  water  supply  and  WaCS  controllers are  high  performance  products  incorporating  this  technology .  Together  with  their  additional  control features  and  simplified  installation,  they  provide  the  best  solution  for  multiple  outlet  demand installations.
