Installation

Provide for a purge of inert gas when you shut down the pumping system, to dilute dangerous gases to safe
concentrations. A suitable gas-ballast control valve for introduction of purge gas into the pump is available
as an accessory (refer to
Section 7.5.15 ).
3.3 Unpack and inspect
1. Remove all packing materials and protective covers and check the pump. If the pump is damaged, notify your
supplier and the carrier in writing within three days; state the Item Number of the pump together with your
order number and your supplier's invoice number. Retain all packing materials for inspection. Do not use the
pump if it is damaged.
2. Check that your package contains the items listed in Table 7 . If any of these items are missing, notify your
supplier within 3 days.
If the pump is not to be used immediately, replace the protective covers. Store the pump in suitable conditions, as
described in
Section 6.1 .
3.4 Locate the pump
The pump can be either free-standing on its box section skids, or be fixed by bolts through the four fixing holes in
the box section skids, or be used with vibration isolators. For the locations of the fixing holes in the box section skids,
refer to
Figure 2 .
Provide a firm, level platform for the pump. Locate the pump so that the oil-level sight-glass is visible and the oil
filler-plug, oil drain-plugs and gas -ballast control are accessible.
If your pump will be located inside an enclosure, make sure that there is adequate ventilation at both ends of the
pump, so that the ambient temperature around the pump does not exceed 40 °C. There must be a minimum space
of 25 mm between the pump and the enclosure walls.
