3.3 Locate the pump
3.3.1 General requirements
You must operate the pump with its inlet-flange
horizontal and at the top.
If the pump will be free-standing, you must support
the backing pipeline to stabilize the pump.
WARNING
Use suitable lifting equipment to
move the pump. If you do not, you
can injure yourself or damage the
pump. Refer to Section 2.3 for the
mass of the pump.
WARNING
You must remove the foam heater
support from the base of the pump. If
you do not, the heater support may
catch fire when you operate the
pump.
WARNING
During operation, surfaces of the
pump are very hot and can cause
injury to people and damage to
equipment. Install the pump so that
people cannot accidentally touch hot
surfaces of the pump.
CAUTION
Ensure that you do not damage the terminal box
when you locate the pump in its operating location.
CAUTION
Ensure that there is a clearance of at least 70 mm
between the pump mounting feet and the nearest
object/surface. Avoid contact between the pump
and combustible materials, plastic materials and
electrical cables. Surfaces of the pump are very hot
and can cause damage to equipment.
Pipelines connected to the pump inlet and outlet
must be self-supporting. Where this is not possible,
ensure that the pipelines impose as small a load as
possible on the inlet and outlet flanges.
Locate the pump at a practical distance from suitable
electrical and cooling-water supplies and so that you
can easily access the dipstick and other components.
Ensure that you leave sufficient access space
(Figure 3, item 6) under the pump, so that you can
replace a heater without having to lift the pump.
Note that surfaces of the pump can get very hot
during operation. Ensure that people cannot
accidentally touch the hot surfaces of the pump. If
necessary, fit guard rails.
3.3.2 Installation on a vacuum system
Note: The centre of mass of the pump on its pallet is
not at the centre of the pallet itself.
1. Refer to Figure 1. Inspect the pump inlet (1) and
outlet (16), ‘O’ rings and ‘O’ ring grooves and
refinish if necessary: refer to Section 3.4.1.
2. Use a wide-track pallet truck or fork-lift to
carefully and slowly move the pump (on its
pallet) under its required operating location.
Ensure that the pump does not topple when
you move it.
3. Use the pallet truck or fork-lift to raise the
pump until the inlet locates onto your vacuum
system flange, then secure the pump inlet to the
vacuum system flange: refer to Section 3.4.2.
4. Undo and remove the bolts, nuts and washers
(fitted through the fixing holes: Figure 3, items
13) which secure the pump to the pallet. Retain
the bolts, nuts and washers for future use (for
example, if you need to move the pump for
maintenance).
5. Lower the pallet clear of the pump. Retain the
pallet for future use.
6. Ensure that the foam heater support remains
attached to the pallet. If necessary, remove the
heater support from the pump.
