EQ Series Pump Installation and User’s Guide

Section 5

Maintenance

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.

WARNING — 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 100 feet or more. These components could

cause severe personal injury or death if they were to strike a person.

WARNING — 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.

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.

WARNING — 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 feet or more.

These components could cause severe personal injury or death if they were to strike a person.
