Chemline Plastics HN Series Hydro Cyclones, designed to separate sand and other solids from surface or ground water. The design is constructed of abrasion-resistant solid plastic. HN Series operates without external power, using centrifugal force. Solids settle into attached bleed tank, which may be flushed using supplied ball valve. Applications include prefiltration on membrane water treatment systems.

The HN Series is offered in three sizes. The one-inch cone is made of glass filled polyamide (PAG), while the two- and three-inch cones are made of glass filled polypropylene (PPG). Other highlights: ends are alfa rapid grooved, MNPT, or MNPT Union; o-rings are nitrile; and bleed tank and flush valve are included.
