Sodium Hypochlorite Systems

Grayledge supplies turnkey Sodium Hypochlorite Metering Skid
Systems that are built for the real world. For instance, the
system below involves a main and back up peristaltic pump for
metering. Why peristaltic? Answer: They are sealless, have no
metallic wetted parts to corrode, do not get air bound/loose
prime and contain no check valves to hang up.
Barnant has a
short write up on
Optimizing Sodium Hypochlorite Feed.
Other features of the system are:
  • Non-corrosive yet durable polyethylene construction
  • Secondary containment with provisions for drainage
    upon extreme high level
  • Pumps are protected from spills by being elevated on
    pedestals
  • Pumps are controlled by digital display controllers that
    accept 4-20mA as well as 0-10 VDC Input Control
    Signals. Pumps can be operated in manual or automatic
    modes
  • Leak detection/no-flow detection with automatic primary
    pump shut off, secondary pump activation and contact
    closures for annunciation or to call an auto dialer.
  • Hoses are securely integrated to the PVC hard piping
    though the use of compression fittings.
