The Knapp Nova-Cast Pig is a custom-designed, all-urethane, one-piece, composite pipeline pig made to accommodate special pipeline configurations with virtually limitless combinations of discs and cups of varying urethane hardnesses. The Nova-Cast is available in configurations that allow the pig to pass through multiple-diameter piping while retaining the ability to scrape paraffin or remove liquids.

This pig is a solid-cast polyurethane pig available for 2” through 8” pipe. It is a bi-directional pig ideal for use in plant and industrial applications. The 8 sealing discs making it very effective in removing liquids in wet gas systems and liquid lines, as well as ideal for product batching, line displacement, and product evacuation.

This pig is a solid-cast polyurethane pig for 2” through 36” pipe. It is available in up to three different durometers for varying projects. The 5 sealing discs and a rear cup design is extremely effective in removing liquids in wet gas systems and liquid lines. The hollow core makes the pig lightweight and uses the line pressure to expand the pig helping to create a superior long lasting seal. This superior sealing capability make it ideal for product batching, line displacement, and product evacuation. Wire Brushes may be added when more aggressive pigging is required as well as transmitters for pig tracking.

This solid-cast polyurethane pig is designed for 2" through 30" pipe and available in up to three different durometers. The unique cup design allows smooth transition with full wall seal through tees, check valves and full opening valves. The hollow core allows expansion while under pressure for maximum performance at all times and may be used to house transmitters for pig tracking. Bolt on wire brushes are available when more aggressive cleaning is required. The Turbo Magnum is effective in removing liquids from wet gas systems and liquid pipelines. Also used to control paraffin build up in crude oil lines, separation of refined products, pipeline commissioning and product evacuation.

This pig is a solid-cast polyurethane pig available for 2" through 8" pipe and is designed to be used with the Argus Pig valve. The disc-cup design combines the effective wiping action of the disc with the superior sealing capabilities of the cup. This pig is effective in removing liquids from wet gas systems and liquid pipelines. It is also used to control paraffin build up in crude oil lines, separation of refined products, and product evacuation.

The TUFFCAST Pig combines conical sealing cups with scraping discs providing both actions in one pig. The solid cast construction makes for a lightweight and economical general purpose cleaning pig. It is made from the same tough LN-10 urethane as our line of Super Pigs. This allows for high abrasion resistance with flexibility to maintain a positive seal in out of round sections of steel pipe.

The TUFFCAST Pig is available in different durometer hardnesses to meet specific pigging requirements. When heavy cleaning capability is needed, the TUFFCAST Pig can be fitted with carbon steel brushes or prostran brushes. The standard brush configuration on the TUFFCAST pig is two brushes, however the pig can be fitted with a single brush if requested.

The TUFFCAST Pig is designed with hollow bodies to allow for the mounting of magnets or pig tracking devices.

The Optima Cast Pig can be configured with any of S.U.N.'s scraper cup or disc designs in any desired arrangement; whether it is a cup-disc-disc-cup design, multi-size cups, or paraffin cups; in any combination desired for up to six sections. The Optima Cast Pig provides the broad range of specialty cups available on the S.U.N. Super Pig with the convenience of a single piece cast pipeline pig. The Optima Cast Pig was designed with a hollow post on all sizes making it easy to equip the pig with a magnetic cartridge for use with the Magna-Sygg Pig Detector, or with a transmitter for use with pipeline pig tracking equipment.

The S.U.N. Super Pig® allows it's users to replace components of the pig as needed. Rather than having to replace an entire pig, the user can simply replace either the cups or discs when they are considered worn out. It's all-urethane design provides a level of safety for the pipeline, as there are no metal parts to worry about. Like all of S.U.N.'s pigs, the Super Pig utilizes the highest quality LN10 formulated MDI urethane for maximum wear resistance.

Available in diameters from 2" - 12", the Super Cast Pig utilizes the same design objectives and construction material as the Super Pig.  The one piece Super Cast pipeline pig offers a logical cost alternative to poly foam pigs and is an ideal product for a broad range of applications around refineries, chemical plants, oil pipelines, gas pipelines, and municipal utility lines. Its urethane allows it to last longer than poly foam pigs and it does not have the same disposal and contamination problems. The Super Cast easily negotiates 1.5D bends, bridge valves and tees without buckling, tearing, or shredding. 

The Urecast Pig incorporates a unique cup and disc combination which provides both optimum sealing and scraping action.

The Ureflex pig is an all-urethane disc pig that can be outfitted with brushes for more aggressive cleaning.

Whether batching or scraping out debris, the BD6K can handle the job. With six urethane discs (2 guides and 4 seals), the BD6K, is a great pig for contractors and operators needing a rugged pig to get the job done. The pig can also be outfitted with gauge plates or brushes.

These steel-bodied scraper pigs are outfitted with neoprene discs instead of urethane. Neoprene has certain qualities and advantages over urethane. Although not as wear-resistant, neoprene generally has a longer shelf-life than urethane and will not crack or get brittle with exposure to the sun. This makes neoprene ideal if you have short pig runs and wish to re-use the pig over the next 3-4 years.

GBD Pigs are designed for Bidirectional operation. For batching, displacement, hydrostatic testing and paraffin removal. Available with 2, 3 or 4 polyurethane discs. Steel wire brushes optional. Pig transmitter mounting optional. GBD pigs have a Center Hole Configuration up to 16" and a bolt hole pattern for sizes larger than 16

GBC Cup pigs are for unidirectional operation. For batching, displacement, hydrostatic testing and paraffin removal. Standard with polyurethane cups.* For gauging, add aluminum or steel gauging plates. Pig transmitter mounting optional for larger diameter pigs. GBC pigs have a Center Hole Configuration up to 16" and a bolt hole pattern for sizes larger than 16".

The Enduro Dual-Diameter Pigs are designed to withstand the heavier wear due to multi-dimensional pipe. This pig provides cleaning action and has proven to hold a great seal through multi-diameter lines. Design may be varied to specific line needs; i.e. bend radius requirement, valve bowl lengths etc. and can also be outfitted with brushes specially designed for multi-diameter cleaning.

A versatile pig available with various cup and disc configurations. The metal pig is useful for cleaning, batching, purging, and paraffin removal.

Enduro's pig train employs the Pig Link concept which allows various configurations and adaptations of cups, discs, and body links. The flexibility of the polyurethane body link allows the pig to pass bend radius as small as one diameter even when attached to additional link sections.
