Unique Operating Features

The Hellan Strainer design provides solids removal without interrupting fluid flow. Instead of trapping solids in a basket which then must be removed for frequent clean outs, the Hellan Strainer removes the solids from fluid without stopping the flow or disassembling the strainer.

Operating features that provide real benefits

  • Eliminate downtime for solids removal
    The Hellan Strainer allows users to eliminate solids and debris from fluids without stopping the the flow of the fluid. Processes requiring the fluid continue uninterrupted. 
     
  • Employees are not exposed to possible contaminates
    Debris that may include contaminates and hazardous materials is removed from the fluid flow without disassembly of the strainer. Maintenance personnel and other employees do not come in contact with this debris. 
     
  • Minimum labor requirements for solids removal
    The Hellan Strainer reduces the time required to remove solids from the fluid flow. Manually opearted models require only a periodic turning of the handwheel to remove solids. Labor and cleaning time is usually less than 30 seconds. Labor requirements can be completely eliminated 
The sequence of operation is listed below: 
  1. Fluid passes into the strainer and through a screen. BACK 
  2. A deflection rib protects the screen from large objects. BACK 
  3. The screened fluid flows out of strainer and into service. BACK 
  4. Rotating the screen either by handwheel or motor, moves the outer screen surface against the scraper bar. The scraper bar removes collected debris from the screens outer surface. BACK 
  5. Debris moves into the sump area of the strainer where it is removed by periodic flushing. BACK 
Special Features provide convenience and high performance.  
  1. Large O-ring sealed inspection ports permit easy external adjustment of the scraper bar. Multiple screen models size 4" and larger, plus 3" single screen models. BACK 
  2. O - rings at the screen cover plate provide a tight seal while allowing operation at low torque. BACK
