Enhancing Strainer Efficiency
Targeted modifications can enhance the performance of automatic self-cleaning scraper strainers, says Robert Presser, President of Acme Engineering Products

For industrial plant managers, automatic scraper strainers are among the closest solutions to a true “set-and-forget” system, effectively removing both large and fine suspended solids from industrial water, cooling tower water, liquids, and slurries.

The basic design represents an efficient and cost-effective industrial self-cleaning strainer. The motorised unit is engineered for minimal maintenance and operator involvement and can remove solids as small as 75 microns. These strainers allow for continuous, uninterrupted flow, including during blowdown cycles.

Cleaning is performed by a spring-loaded blade and brush system controlled by a fully automatic control unit. The two blades and two brushes rotate at 8rpm, producing an effective cleaning rate of 32 passes per minute. The scraper brushes penetrate the wedge-wire slots to dislodge stubborn particulates and adhered solids.
