clean to ensure that site debris is not drawn
into the pump when it is commissioned.
4.7 Discharge Pipework
Pipework should be as short and straight as
possible to reduce friction head loss.
A non-return valve is usually fitted to
prevent the pump from excessive back
pressure and reverse rotation and a
discharge valve must be fitted to regulate
the flow and allow for inspection and
maintenance on the pump.
The suction and discharge pipework must
be independently supported and positioned
such that no excessive forces and moments
are exerted on the pump flanges.
Typical Pipework
XFPIPE1.CDR
Failure to support suction and delivery
pipework may result in distortion of the
pump casing, with the possibility of early
pump failure.
4.8 Mechanical Seal Vent Pipe
The mechanical seal oil chamber is fitted
with a clear plastic vent pipe. This is to be
routed to a suitable drain point or into the
bund. It is important to be able to see any
fluid discharge from this pipe.
4.9 Baseplate and Foundations
The pump is designed to be secured to a
substantial baseplate to maintain the shaft
alignment between the driver and the pump.
The baseplate should be securely located
on level ground or mounted on foundations.
The shaft alignment should be checked
again before commissioning and putting the
pump into operation.
5. COMMISSIONING AND
OPERATION
Abrasion & Entrapment Hazard
Do NOT touch any moving or rotating parts.
Guards are provided to prevent access to
these parts, where they have been removed
for maintenance they MUST be replaced
before operating the equipment.
5.1 Commissioning Checks
These checks must be done after first
installation and after pump maintenance
that required removal of the rotating
assembly or draining of the bearing housing
and mechanical seal oil chambers.
Check the oil level in the mechanical seal oil
chamber sight glass.
Check the oil level in the bearing housing oil
chamber sight glass is at the level mark in
the centre of the glass.
Initial checks of oil level should be done
with the pump level to prevent misleading
readings.
The maximum inclination of the pump from
horizontal in any direction when running is 5
degrees
Refer to Section 6.4 - Bearing Lubrication.
Do not overfill the bearing and seal oil
chambers as this will cause overheating
and leakage.
