Cleaning of the Strainer Basket
1. The pump is designed to be maintenance free with the exception of requiring a periodic cleaning of the
strainer basket.
2. A routine inspection should be done by visually looking through strainer lid for debris while the pump is in
operation. The strainer basket should be cleaned when approximately 25% blocked. Allowing the strainer
basket to become excessively blocked will diminish water flow, reduce pump efficiency, cause cavitation and
may damage the basket or other pump components.
3. Disconnect power to the pump before cleaning the basket.
4. Close isolation valves on the suction and discharge lines if necessary to prevent flooding.
The strainer pot may be at a pressure that is higher or lower than the atmospheric pressure. Always open the
drain plug on the strainer pot and allow for the pressure to equalize before removing the locking ring. Attempting
to remove the locking ring before the pressure is equalized may result in a rapid exchange of pressure. This instantaneous release
of energy can cause components to be accelerated to high velocities and to travel distances of or 100 ft (30.5 m) or more. These
components could cause severe personal injury or death if they were to strike a person.
If the pump has been energized for a period greater than 45 minutes without water flowing through the pump for any
reason, the water in the strainer pot may be hot. Attempting to remove the locking ring without removing the drain
plug in the pot and allowing the pressure to equalize may result in the hot water rapidly escaping and causing severe personal injury.
5. Open the drain plug in the strainer pot and allow the pressure to completely stabilize.
6. Remove the locking ring and the clear lid from the strainer pot.
7. Remove the basket and dispose of the debris. Use a water hose
and soft brush to remove debris blocking the openings in the basket
if required.
8. Replace the basket making sure it is properly oriented.
9. Replace the lid, by aligning the four tabs with the tabs on the
strainer pot and making sure the O-ring is clean and is properly
located in the groove of the lid.
Note: The lid must be properly aligned before the locking ring
will seat completely. Ensure that the notch in the lid is properly
aligned with the tab in the strainer pot, (see Figure 7). Also
ensure that the locking ring is aligned properly before tightening.
If the locking ring is misaligned, the handles will interfere with
the pump before the locking ring is completely locked, (see
Figure 8 on page 10).
10. Secure the lid in place by tightening the locking ring hand tight
only. Do not over tighten the locking ring as that will make removal
difficult.
It is recommended that only water and a soft cloth be used to clean the lid and other pump components. Cleaners
may contain chemicals that could damage or weaken pump components causing them to fail and allowing an
instantaneous release of energy. This instantaneous release of energy can cause components to be accelerated to high velocities
and to travel distances of 100 ft (30.5 m) or more. These components could cause severe personal injury or death if they were to
strike a person.
