On receiving
your Flojet diaphragm pump
check that the pump and model number and
motor volts/phase/Hz correspond to your
purchase order. Notify your supplier
immediately in the event of any error, or of
damage to the pump on receipt. Delay may
cause difficulty with warranty claims.
Installation.
Locate the pump in a dry
place above or below the liquid supply. The
pump will self-prime when wetted to a height
not exceeding 2 metres. The pump may be
mounted in any attitude. If mounted
vertically, the motor should be uppermost.
The drain holes in the pump body should face
downwards: if necessary, undo the 4 body
screws and rotate the pump head through 90º
or 180º. Attach the pump to a firm surface
with fixing screws through the mounting feet.
Connections.
Port adapters available are
13mm (½”) hose barb and ½” NPT threaded.
Use hose clips for hose connections and
PTFE tape for threaded connections.
Flexible hose is recommended. Inlet hose
should be at least 13mm (½”) bore, of the
reinforced type that will not deform or
collapse under suction conditions.
A ‘Pumpguard’ strainer is recommended to
prevent solid debris from entering the pump.
The strainer should be checked at intervals
and cleaned when necessary. See Cleghorn
Waring’s data sheet for details of
‘Pumpguard’ strainers and port fittings.
Make sure that the inlet and discharge pipes
and connections are airtight, to ensure
prompt self-priming and no leaks.
Electrical connection.
The unit is
complete with a standard European single
phase 3 wire lead. Check the motor plate for
the correct electrical supply and full load
current. Make sure that the motor (and
adjustable pressure switch, if fitted) are
earthed. A starter with thermal overload
protection should be used to protect the
motor. A COMPETENT ELECTRICIAN
SHOULD DO THE WIRING.
Controlling the discharge pressure
.
The maximum recommended discharge
pressure is 3.0 bar (45 p.s.i.). The pump is a
positive displacement type that can be
damaged by excessive back pressure.
