Mainteno® Scrapper
Online-cleanable strainer with an internal scrapping arrangement for viscous, sticky and fouling service.
Product overview
Where back-flushing alone will not clear the screen, the Scrapper adds a mechanical element that wipes the screen face from inside the body. Available in manual, semi-automatic and automatic configurations depending on how often the duty demands it.
The problem it solves
Viscous and sticky media do not blow off a screen. They build a layer that flushing cannot shift, so the strainer is either bypassed — leaving downstream equipment unprotected — or opened repeatedly for manual cleaning.
Working principle
A scrapper element traverses the inner face of the screen, shearing the deposited layer off the mesh and dropping it into the collection chamber, from where it is discharged through the drain connection. The line stays in service throughout, and the cleaning interval can be put on a timer or a differential-pressure signal.
