Suction Line Strainers

Suction line strainers are used to provide dependable protection against sediment filtering into pumps and equipment. Ron-Vik offers a wide variety of suction line strainers so there is a model for most applications.

The base of the suction line strainer is available in Polyvinyl Chloride (PVC) or Nylon. As the chart on the reverse shows, there is a variety of standard base fittings. Standard meshes are 20x20, 30x30, 40x36, 50x50 or 80x80 type 304 stainless steel, although Ron-Vik can customize the strainer for almost any screen including different mesh counts and T316, brass or monel mesh.

Base Materials

Nylon: Type 6/6 black nylon is used to manufacture a base that is extremely durable and offers a wide range of chemical compatibility.

PVC: Black vinyl plastisol (PVC) in a 70 durometer shore A is used to manufacture bases that are flexible yet durable and economical. Note: If the installation puts this base in direct contact with any styrene based components please advise your customer service representative as our standard material is not recommended.

Mesh Materials

Standard
Stainless Steel type 304: The basic stainless alloy (18% chrome, 8% nickel) and the most extensively used to weave wire cloth. It has excellent corrosion resistance which is satisfactory for most applications. Where no type is specified, it is assumed that type 304 is acceptable.

Optional*
Stainless Steel type 316: The same characteristics as type 304 with an additional 2% molybdenum to provide increased corrosion resistance to salts and acids. In addition it has increased strength at high temperatures.

Brass: Standard brass (copper 65%, zinc 35%) has high strength and ductility for severe cold with a mild corrosion resistance.

Monel ® alloy 400: A high nickel copper alloy which is one of the most widely used alloys for corrosion resistance. It has the strength of a mild steel and will not corrode in a great many solutions found in industrial applications. *Limited availability and lead times apply.

PVC Based

A pot-molded 70 durometer Shore A Polyvinyl Chloride base is permanently bonded to the one-piece wire cloth strainer. Common applications for PVC suction line strainers include pool and spa equipment, water softeners, floor cleaning machinery, pressure washers and car wash equipment.

Nylon Based

The injection molded nylon base is either bonded to the wire mesh by urethane adhesive or in applications where the urethane adhesive is not desirable we can adhere the screen to the base by method of induction welding*. Some of the many markets nylon suction line strainers are used for include hydraulic systems, paint spraying equipment, parts washers and chemical handling equipment.

Both PVC and nylon base suction line strainers can be easily removed for cleaning or replacement. If our standard models do not meet your needs please contact sales or customer service to discuss custom specifications and configurations.
