NOTE: National Line™ 30 and 65 P.S.I.G. Strainers are certified by NSF International to ANSI / NSF Standard 50 for both pool and spa applications at flow rates of 50 to 2,4000 U.S. GPM with 0 P.S.I.G. head loss when operated at rated flow with a clean strainer basket.

ENGINEERING NOTES: National Line™ Strainer dimensions should not be used for construction or installation purposes unless confirmed by Nemato Engineering Staff.

NATIONAL SERIES STRAINER ELEMENT FLOW

CHARACTERISTICS

TMATIONAL LINE


EMATO CORP.

NATIONAL SERIES STRAINERS

NATIONAL SERIES STRAINER BASKET

100% Open Basket Flow Flow is evenly balanced with minimal head loss in the element and body. The water velocity is below the settling rate of some of the debris.

75% Open Basket FlowFlow is concentrated in 75% of element with minimal head loss in the element and body. The bottom of the element has plugged first due to settling of debris. Flow velocity is accelerating in upper half and decreasing in lower half of the body.

50% Open Basket FlowFlow is concentrated in 50% of

element with minimal head loss in the element. Head loss starting to

rise due to increased flow in the upper half of the body.

25% Open Basket FlowFlow is concentrated in 25% of element with a rise in head loss

in the element. Head loss is high in the body due to a

concentrated flow in the upper half of the body.

Vent plug

Through the use of a proprietary vertically pleated corrosion resistant non-welded strainer basket, the strainer produces 0-P.S.I.G. head loss when operating at designed flow rates. The strainer basket consists of food grade FRP end caps, 16- gauge stainless steel straining element with 1/8” perforated holes and stainless steel connecting rods. All strainer baskets have a minimum of a 4 to 1 open area ratio of the strainer basket to influent flange connection. The vertically pleated strainer element acts as a flow baffle providing for full use of the open area in the strainer basket, which results in longer operation without excessive cleaning.

Removal of the strainer basket is simplified through a proprietary design allowing for drainage of water, while maintaining strained debris retention, during lifting of the basket. All strainer baskets are self aligning during installation and come with a molded flow indication arrow to insure proper flow direction.

NATIONAL SERIES 30 P.S.I.G. STRAINERS

NATIONAL SERIES 65 P.S.I.G. STRAINERS

TMNational Line 30 P.S.I.G. strainers are constructed of food grade Fiberglass Reinforced Isophthalic or Vinylester Resin (F.R.P.), PVC and stainless steel material. The strainers are totally non-corrosive and have a high gloss gel-coat finish with UV protection. The strainers are manufactured utilizing a patented process that provides mechanical properties that are two to five times greater than traditional F.R.P. manufacturing processes or eight times higher than traditional PVC materials. The strainers are designed for working pressures up to 30 P.S.I.G. and a vacuum service up to 20” of mercury. A proprietary interlocking design between the strainer body and lid as well as a food grade EPDM square ring provides manual opening as well as hand tightened sealing of the lid to the body at 45 P.S.I.G.

All National strainer designs come with 2” to 14” integrally molded influent/ effluent vanstone flange connections, F.R.P. cover with clear acrylic viewing window, stainless steel j-bolt fastening hardware and drain/ vent plugs. The strainers come in three body diameters (6”, 10”, and 16”) with straight or reducing pipe configurations. NSF International certifies all National 30 P.S.I.G. strainers to ANSI/ NSF Standard 50 for both pool and spa applications.

National 65 P.S.I.G. strainers are constructed of food grade Fiberglass Reinforced Isophthalic or Vinylester Resin (F.R.P.), PVC and stainless steel material. The strainers are totally non-corrosive and have a high gloss gel-coat finish with UV protection. The strainers are manufactured to ASTM and ASME standards utilizing a patented process that provides mechanical properties that are two to five times greater than traditional F.R.P. manufacturing processes or eight times higher than traditional PVC materials. The strainers are designed for working pressures up to 65 P.S.I.G. and a vacuum service up to 20” of mercury. A proprietary interlocking design between the strainer body and lid as well as a food grade EPDM square ring provides manual opening as well as hand tightened sealing of the lid to the body at 100 P.S.I.G.
