INSTALLATION
1.1 INSTALLATION AND SAFETY
RECOMMENDATIONS
In common with other items of process plant a pump
must be installed correctly to ensure satisfactory and
safe operation. The pump must also be maintained
to a suitable standard. Following these
recommendations will ensure that the safety of
personnel and satisfactory operation of the pump is
achieved.
1.2.1. GENERAL
When handling harmful or objectionable materials,
adequate ventilation must be provided in order to
disperse dangerous concentrations of vapours. It is
recommended that wherever possible, Mono pumps
should be installed with provision for adequate
lighting, thus ensuring that effective maintenance
can be carried out in satisfactory conditions. With
certain product materials, a hosing down facility with
adequate draining will simplify maintenance and
prolong the life of pump components.
1.2.2. SYSTEM DESIGN & INSTALLATION
At the system design stage, consideration must be
given to provision of filler plugs, and the
installation
of non-return and/or isolating valves. Pumps cannot
be reliably used as non-return valves. Pumps in
parallel and those with high static discharge head
must be fitted with non-return valves.
The pumps must also be protected by suitable
devices against over pressure and dry running.
i. HORIZONTAL MOUNTING
All ranges excluding P Range Mono pumps are
normally installed in a horizontal position with
baseplates mounted on a flat surface, grouted in
and bolted, thus ensuring firm fixing and a reduction
in noise and vibration.
The unit should be checked after bolting down to
ensure that the alignment of the pump to its prime
mover is correct.
ii. VERTICAL MOUNTING
P Range Pumps Only
The P range pumps are intended for vertical
installation. Care must be taken when lifting the
pump into the vertical position.
Normally 'P' range pumps will be designed with a
sole plate that will be bolted
to the customers
framework.
If the pump is to be mounted in any way other than
described above, confirmation of the installation
must be agreed with Mono Pumps Limited. All the
pipework should be independently supported.
1.3.1 HANDLING
During installation and maintenance, attention must
be paid to the safe handling of all items. Where a
pump or its components weigh in excess of 20 kg
(45lb) it is recommended that suitable lifting tackle
should be used to ensure that personal injury or
damage to components does not occur.
For safe handling of both bareshaft pumps and
pump units (pump/ gearbox/motor etc.) slings should
be used. The position of the slings will depend upon
the specific pump/unit construction and should be
carried out by personnel with the relevant
experience to ensure that the pump is not damaged
and injury to personnel does not occur.
If eyebolts do exist then these should only be used
for lifting the individual com
ponents for which they
are supplied.
1.3.2 STORAGE AND INFREQUENT OPERATION
The situation where a pump is used infrequently is
also covered by the instructions in this section.
SHORT TERM STORAGE
Where a pump has to be stored for 6 months or
less then the following steps are advised:-
1. Store pump inside wherever possible or if this is not
feasible then provide protective covering. Do not
allow moisture to collect around the pump.
2. Remove the drain plug, if fitted. Any inspection
plates fitted should also be removed to ensure that
the suction housing can drain and dry completely.
3. Loosen the packed gland and inject sufficient grease
into the stuffing box. Tighten the gland nut hand
tight. If a water flush system is to be used do not
grease, a small amount of light oil is recommended
for these.
4. See Manufacturers Instructions for
motor/gearbox/drive instructions for storage
procedures.

Installation, Operation & Maintenance Instructions
Pumps operating on high temperature duties
should be allowed to cool sufficiently before any
maintenance is carried out.
