stainer is equipped with a blow-down valve.The strainer
is a 16 mesh (approximately 1 mm) material.
Figure 106. Water strainer - Y type
For maximum efficiency, a differential pressure gauge
installed across the inlet and outlet will indicate pressure
loss due to clogging and may be used as a guide to
determine when cleaning is required.The taps for the
pressure gauges are included as standard from the factory.
Normally when differential pressure reaches 5-10psi, the
screen must be cleaned.The strainer is equipped with a
blow-down valve on the cover plate.To clean open and
flush out until any sediment is removed.

Pump Package Maintenance

Rust Prevention
Pumps not immediately placed into service, or removed
from service and stored, must be properly prepared to
prevent excessive rusting.
• Pump port protection plates must not be removed until
the pump is ready to connect to the piping.
• Rotate the shaft periodically (at least monthly) to keep
rotating element free and bearings fully functional.
• For long term storage (3 months or longer), prevent
internal rust buildup and possibility of freezing by
performing the following steps:
• Remove the plugs at the top and bottom of the
casing.
• Drain or blow out all water.
• As an optional step, it is acceptable to rustproof
or pack the casing with moisture absorbing
material and cover the flanges.
When returning pumps to service
• Remove drying agent from the pump, if used.
• Reinstall plugs at the top and bottom of the casing.
