ACME - Model ACRS Series - Automatic Scraper Strainer
From ACME - Strainers
The ACME Automatic Scraper Strainer has been designed to remove solids from 150mm in size down to 75-micron particles. The general literature piece describes the various connection options available as well as the advantages of a scraper strainer over a backwash strainer. These strainers are available with connections from 1″ up to 48″ in fabricated carbon steel, stainless steel, and various alloys such as Alloy 20 and Monel.

Products Details
All internal components, including the wedge wire screen, are constructed of SS316L or other alloys for durability and longevity. Special designs are available for viscous fluids, suction-side installations, and jacketed vessels. All strainers are fabricated to the exact design requirements of each client and are still cost-competitive with cast-vessel backwash strainers from Acme's main competitors.
ACRS strainers can now be ordered with FRP vessels for maximum corrosion resistance in seawater or process applications.

- Fused circuit and magnetic starter with overload for the scraper motor.
- Adjustable cycle timer for the scraper motor and blowdown valve operation.
- Differential pressure switch for scraper motor operation.
- Blowdown valve –electrically or pneumatically actuated.
- Integral audible and visual alarm circuit with contacts for remote supervision.
Options:
- 230V, 380V, 440V, 575V, 1 PH or 3 PH, 50 or 60Hz.
- Disconnect switch, door interlocked.
- Control of other ?ltration system components, such as pumps, ?lter presses, automatic
- valves, associated controls, etc, all to be incorporated into a single ACME control system.
- PLC control of the complete system as above.
- Pneumatic interface for valve actuation or other pneumatic items included in the above.
- Control of isolating knife gate valves and ?ushing solenoid valves associated with waste collector systems attached to the scraper-strainer.
- Control of vacuum pumps in the drain line for ACME Scraper-Strainers installed on the suction side of main system pumps
