3. Pump Connections
Accurately align the connecting flange with the pump port before it is
tightened. To prevent problems, avoid pulling the pipeline into
alignment by tightening the flange bolts and/or couplings.
All lines surrounding the pump
must
be supported independently to
alleviate strain on the pump. Without adequate support, the lines may
cause heavy vibration, excessive seal and shaft wear, and reduce the
life of the bearings. When using hose lines, you must have adequate
support to ensure their reliability and operator safety when filled with
pressurized liquid.
4. Gauges
A majority of pumps are pre-drilled and tapped for installation of
suction vacuum and discharge pressure gauges. When adding
gauges to pumps without tapping, drill and tap both suction and
discharge lines to a minimum of 18-inches (457 mm) away from their
respective ports. Once this is done, install the lines. Avoid installing
gauges any closer to the pump, since closer installation may result in
incorrect readings.
E.
SUCTION LINES
Be sure the suction line is both short and direct to eliminate air pockets. Air
pockets may adversely affect pump priming. Operation requiring suction lift
from the source liquid being pumped
must have
a line that slopes upward
to
the pump. Should the line slope downward anywhere along the suction run,
air pockets reducing performance will occur.
1. Fittings
The pump inlet requires that suction lines are the same size as the
pump inlet. Should reducers be necessary, they must be the
eccentric type of reducers. Install eccentric reducers with the flat part
uppermost. This eliminates air pockets.
Valves are rarely used in suction lines; however, if a valve is needed,
it should be installed with the stem horizontal. This eliminates air
pockets that reduce performance.
2. Strainers
Be sure to use any strainer included with your pump since spherical
solids passing through the strainer will also move through the pump.
When no strainer is included, but you opt to install one, be sure the
complete area of the strainer openings is 3 to 4 times the suction
