Mainteno® Inverted
Inverted suction strainer with a sparger arrangement that allows inline cleaning on the suction side.
Product overview
An inverted or suction-side strainer arranged so that the screen can be cleaned in line through a sparger, protecting a pump without introducing a component that has to be isolated every time it chokes.
The problem it solves
Suction-side strainers are the most awkward to clean and the most damaging when they choke. A partially blocked suction screen starves the pump, drops NPSH available and leads to cavitation long before anyone thinks to look at the strainer.
Working principle
The inverted geometry collects debris where it can be purged rather than where it sits against the flow path. A sparger arrangement directs cleaning flow across the screen so the collected solids are lifted and discharged without lifting the element out of the body.
Applications
- Pump suction protection on condensate and water circuits
- Suction-side duties where NPSH margin is tight
- Tank outlet and recirculation lines
- Applications where suction strainer cleaning has caused repeat pump damage
