IHB SERIES

Sample Specifications

Separator Type & Performance
The removal of specific unwanted sand from a pumped/pressurized water system shall be accomplished with a centrifugal-action vortex separator.  Sand removal efficiency is principally predicated on the difference in specific gravity between the sand and the water.   Performance is expected to be 98% removal of 74 microns and larger.   Additionally, particles finer in size will also be removed, resulting in an appreciable aggregate removal of particles (up to 75%) as fine as 5 microns.

Performance Requirement

Separator performance must be supported by published independent test results from a recognized and identified test agency.  Standard test protocol of upstream injection, downstream capture and separator purge recovery is allowed with 50-200 mesh particles to enable effective, repeatable results.  Single-pass test performance must not be less than 95% removal.  Model tested must be of the same flow-design series as specified unit.

Separator Design & Function
A tangential inlet and mutually tangential internal accelerating slots shall be employed to promote the proper velocity necessary for the removal of the separable sand.  The internal accelerating slots shall be spiral-cut for optimum flow transfer, laminar action and particle influence into the separation barrel.  The separator’s internal vortex shall allow this process to occur without wear to the accelerating slots.

Separated particle matter shall spiral downward along the perimeter of the inner separation barrel, in a manner which does not promote wear of the separation barrel, and into the solids collection chamber, located below the vortex deflector stool.

To insure maximum particle removal characteristics, the separator shall incorporate a vortex-induced pressure relief line (Vortube), drawing specific pressure and water from the separator’s solids collection chamber via the outlet flow’s vortex/venturi effect, thereby efficiently encouraging sand into the collection chamber without requiring a continuous underflow or excessive system water loss.

System water shall exit the separator by following the center vortex in the separation barrel and spiral upward to the separator outlet.

Purging
* Evacuation of separated sand shall be accomplished automatically, employing a timer-activated motorized ball valve.  The timer, programming switches and motorized actuator shall be mounted directly onto the valve.  Straight-through valve design, with bronze valve body (also available optionally as a stainless steel valve body) and stainless steel ball in a teflon seat.  NEMA 4 housing for indoor or outdoor installation.  Valve size:  ________

Separator Details
A. Inlet & outlet shall be grooved couplings, size: _____
B. Purge outlet shall be threaded, size: _____
C. The separator shall operate within a flow range of: __________
D. Pressure loss shall be between 3-12 psi (0.2-0.8 bar), consistent with the above flow range.

Separator Construction
The separator shall be of unishell construction with SA-36, SA-53B or equivalent quality carbon steel, minimum thickness of .25 inches (6.35 mm).  Maximum operating pressure shall be 150 psi (10.3 bar), unless specified otherwise.

Paint coating shall be acrylic urethane, spray-on, gloss green.

As a specified option only:  The separator shall be constructed in accordance with the standards of the American Society of Mechanical Engineers (ASME), Section VIII, Division 1 for pressure vessels.  Certification shall be confirmed with the registered “U-stamp” on the body of the separator.

Separator Source & Identification
The separator shall be manufactured by LAKOS Filtration Systems, a division of Claude Laval Corportation in Fresno, California USA.  Specific model designation is: __________________
