Materials :
Fabricated to carbon steel as standred.
Size :
From 6’’ N.B. to 20” N.B.
Standard features of these filters are that these are fabricated from carbon steel with bolted cover. The number of basket depends on flow rates and pressure drop requirements.
Baskets are available in stainless steel or plated with dull nickel with 3mm dia perforation and 20 S.W.G. as standard.
These strainers are for temporary installation during the commissioning or start up phase of systems to protect equipment from damage caused by the passage of construction, fabrication debries.
Standard Features :
• Straight through flow passage resulting in low flange pressure loss.
• Custom designed to suit specific applications.
• Idealy suited to pump suction duties and high velocity applications such as Turbine meter protection duties.
• Compact light-weight design lends itself readily to offshore installations where space and weight are critical.
• Sizes available from 4” bore up to 60” bore pipelines (larger sizes available on request).
• Units available for any pressure rating from ANSI 150lb up to ANSI 2500lb (BS table, DIN or other flange standards
available on request).
• Designed in accordance with ANSI B31.3,ANSI B31.4,ASMEVIII Div 1 or BS 5500 design codes.(Other codes available on
request).
• Units available with bolted or quick-release covers.
• Body available in carbon steel, lined or unlined, stainless steel or cupronickel material.(other materials available on
request).
• Screen material available in mild steel, stainless steel or Monel.
• Filtration normaly 3mm perforations down to 80 mesh (200microns).
The motorized, automatic, self-cleaning strainer, provides continuous debris removal from fluid piping systems that demand full time uninterrupted flow.
Sequence of operation :
• Debris laden fluid enters through inlet to inner chamber.
• Dirty fluid flows upward and outward through the strainer element (A).
• Debris is retained on the flat face of the strainer element, while strained fluid continuous to outer chamber and exits
through strainer outlet.
• During backwash or cleaning cycle, the motor/gear reducer (B) is engaged and drives the hollow drive shaft (C) and
hollow port (D) around the inner circumference of the strainer element.
• The backwash assembly (E) is opened to atmospheric pressure by opening the backwash control valve (Electricaly
Operated).
• Flow reversal occurs at the port/straining element (F) interface because of the pressure differential.
• Debris is effectively vacuumed from the full length of the straining element by a vigorous reverse fluid flow and into the
hollow port; down the hollow drive shaft and out the backwash outlet (G).
• The hollow port continues to sweep the full length of the strainer element until the cleaning cycle has ended.
• The strainer will provide continuous uninterrupted fluid flow during the cleaning operation.
• The cleaning cycle can be set for continuous or intermittent backwash.
The general purpose of these size of “Single Basket” filters with quick release cover are for easy maintenance. The design does not require special tools or knowledge and results in a minimum down time, suitable for both liquid gas.
Materials :
Cast iron ,cast steel, Stainless Steel fitted wiyh stainless steel/mild steel basket. Depending upon the degree of filtration and pressure drop required, the replaceable inserts are fitted.
Application :
Single basket filters and strainers are used where ‘flow’ can be interrupted to allow removal of elements for cleaning. These types of filters/strainers provide necessary protection for efficient operation of pumps, meters, heat-exchangers, control valves etc.
