Mounting Foot Securing
Some pumps within the range are fitted with plastic mounting feet. If there is a
requirement to secure the pump via the mounting feet, the following points should be
noted.
The pump should be mounted only in the horizontal position.
Floor mounting is the preferred
orientation but wall mounting is
possible providing all fixing
holes provided are used.
*Air locking possible. Special care
required to vent the pump casing
of air with this orientation.
The mounting bolts
used to secure the
pump must be fitted
with a plain washer to
distribute clamping
load evenly across
load bearing face of
foot.
Pump Mounted Above Liquid Source (Suction Lift)
The pumps can be used in a suction lift installation providing the height of lift is within the
limits specified in the limits of application section (Fig. 8).
A footvalve and strainer must always be used (except X201 when used on a self priming
installation) and the suction pipework size must match the pump.
Lay the suction piping over the shortest possible distance and ensure there is a constant
rise from the liquid source to the pump. Any high spots will cause air pockets to form,
reducing system efficiency.
Ensure all joints in suction pipework
are completely airtight. Failure to
comply will result in loss of prime.
The intake of the footvalve/strainer
should be positioned such that it cannot
be blocked with debris or silt that are
frequently found in the bottom of sumps
and wells.
When a footvalve is installed on
installations that incorporate automatic
pump control, it is recommended that a
suitable pressure relief valve be fitted in
the discharge (outlet) pipework from the
pump.
