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.
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.
Heavy-duty reinforced chemical suction and discharge hose
Use for: Reinforced 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 main selection is for compatible cesspool vacuum pickup. Reinforced pressure transfer is a separate duty listed under Products.
Exception: flexCHEM™ 220 remains the general waste-handling selection. flexCHEM™ 300 can be the appropriate choice when the identified waste requires compatible EPDM construction or a different available diameter. Identify the fluid, concentration, temperature, contaminants and cleaners; verify compatibility of the hose, fittings and seals and the selected diameter’s operating limits.
