Literature and Documents

  • Simplifies the installation and removal of a submersible pump from a basin.
  • Economical - reduces time and cost of removing pump from basins less than 8' (2 m) deep
  • Safety - keeps personnel out of pits and out of contact with contaminants
  • Inspections made fast and easy


Z-RAIL® DISCONNECT SYSTEMS (1-1/4" to 3" vertical discharge):

  • Used with threaded vertical discharge pumps
  • Ductile iron stationary disconnect, rail plate and guide and upper rail support
  • 304 stainless steel hardware
  • Positively seated with a Buna-N seal ring
  • 3/4" guide rails (not included) direct the pump to its proper seating location
  • Non-sparking design for Class I Division 1 Group C & D locations
  • Intermediate stabilizer bracket recommended for basins greater than 12' (3.6 m) deep

P/N 10-0789 lifting bails are required on 6160, 6180, 6280, 6290, 7010 and 7020/7021 models to balance pump and rail plate evenly. Other models already include proper lifting device.
Stainless steel lifting cables available.


SQUARE GUIDE RAIL SYSTEMS (1-1/4", 1-1/2", 2" discharge):

  • Single, rigid stainless steel square rail design
  • Stainless steel rail, nuts, bolts, fasteners and lifting bail
  • Cast iron pump guide bracket
  • Galvanized piping, stainless steel optional
  • Red brass disconnect fittings with Teflon coated Buna O-ring seal
  • PVC ball valve
  • Cast iron check valve
  • Stainless pull rods and lifting cable available
  • Available in prepackaged fiberglass basins

For tanks deeper than 72" (182 cm), a second angle arm bracket (P/N 39-0070) is required. Sch. 40, galvanized or stainless steel pipe is used for extending the rail length.


FLANGED RAIL SYSTEMS (2-1/2" to 6" horizontal discharge):
 

  • Used with flanged horizontal discharge pumps
  • An ANSI flange pattern for universal adaptability to most submersible pumps
  • Robust Class 30 cast iron construction
  • Powder coated epoxy protection
  • 304 stainless steel hardware and rail guides
  • Positively seated with a Buna-N seal ring
  • 2" (5 cm) guide rails (not included) direct the pump to its proper seating location

1/4" (6 mm) lifting cable not included. See ZM1328 for correct cable.
One intermediate guide rail bracket is required for every 20' (6 m) for 3" (76 mm) system, or 15' (5 m) for 4" (102 mm) system, of basin depth.


3", 4", 6" FLYGT GUIDE RAIL SYSTEM ADAPTERS

  • For retrofitting 3", 4" or 6" horizontal discharge pumps to existing Flygt rail systems.
  • Cast iron construction
  • Flange conforms to ANSI B16.10 fully flat/MSS SP-6
  • For use with all 6400, 61 HD and 6700 series pumps with 3", 4" or 6" discharges and 2" NPT rail pipe
  • Flange gasket and stainless steel bolts included


DISCONNECT SYSTEMS

Reduces time and cost of removing a pump. Disconnect only (1-1/4", 1-1/2" and 2" discharge).
  • Disconnect fitting used for shallow systems where guide rails are not necessary.
  • Pull rod not included.
