PRODUCTS / INDUSTRIAL HOSE / WATER HOSE / FLEXIBLE LAYFLAT WATER DISCHARGE HOSE
APPLICATION
Flexible Layflat Water Discharge Hose
WELLMAN 300 flexible layflat riser hose for submersible pumps, supplied in one continuous length to the pump setting with no joints except at the pump and headworks. All-synthetic: polyurethane lining and cover resistant to hydrocarbon fuels, many chemicals, ozone, UV, abrasion and microbial attack; the textile reinforcement swells up to 15 % under pressure to cut friction loss. Working pressure is 50 % of burst (2:1) for non-hazardous, non-flammable liquids.
CONSTRUCTION
Single-length woven riser, zero-corrosion synthetic build
TUBE
High grade polyurethane lining
REINFORCEMENT
Woven synthetic textile, engineered to swell up to 15% under pressure
COVER
Polyurethane, resistant to hydrocarbons, ozone, UV and microbial attack
