Application guide
All purpose chemical suction and discharge hose
flexCHEM™ 300 is the EPDM chemical, water and liquid-waste option. Its suitability depends on the exact fluid; the EPDM designation does not establish universal chemical or petroleum compatibility. Use 300GR for an identified liquid-dominant stream requiring EPDM compatibility.
Heavy-duty abrasion resistant chemical suction and discharge hose
flexCHEM™ 220 is the SBR liquid-waste and vacuum-truck option. Its smooth outside diameter supports handling, while its construction suits compatible waste streams and suspended solids. Use 220RS where its compatible liquid-waste construction and smooth exterior control selection.
Heavy-duty abrasion resistant suction and discharge hose
flexVAC™ 180 AR is the heavy-duty abrasion-resistant SBR material-handling option. It provides strong suction capability in a broad size range, but it does not contain a hose-grounding wire.
Heavy-duty reinforced chemical suction and discharge hose
Use for: Reinforced EPDM pressure transfer.
flexCHEM™ 390 adds synthetic reinforcement and higher working-pressure capability for compatible EPDM service. Its listed diameters extend through 3 inches; this is a pressure-transfer upgrade, not an automatic vacuum-pickup upgrade.
Notes: The Best Value selection covers identified SBR-compatible mixed-solids recovery. Liquid-dominant EPDM service and reinforced pressure transfer remain distinct duties.
Distinction: flexCHEM™ 300 suits compatible liquid-dominant EPDM service. flexCHEM™ 220 addresses compatible sludge and suspended solids. flexVAC™ 180 AR addresses SBR-compatible recovery where abrasive grit and debris dominate. The flexCHEM™ 390 alternative is for reinforced EPDM pressure transfer.
Warning: Sludge may contain acids, alkalis, oils, solvents, biological waste and treatment chemicals. Identify the liquid phase, solids concentration, temperature and contaminants. Verify compatibility of hose, fittings and seals and the selected diameter’s pressure, vacuum and bend-radius limits.
