Our 100mm (4 inch) suction and delivery hose is a large-bore option for high-volume work, matched to the 4 inch ports on big dewatering, trash and engine-driven pumps. At this size the suction load is significant, so the nylon spiral-helix reinforcement is essential: it keeps the full bore open under heavy vacuum so the pump achieves its rated flow rather than starving against a collapsed hose.
It is built for serious site and flood-response duty, moving large volumes from excavations, lagoons, watercourses and major basement floods. The heavy-duty PVC wall withstands traffic, abrasion and permanent burial, and serves on both suction and delivery sides. At 2.22 kg per metre it is best handled in shorter working lengths. Rated to 3.5 bar and supplied in 6m, 10m, 15m, 20m and 30m coils.

Layflat hose is very affordable but can kink. Depending on your use, you may be better using a reinforced suction delivery hose for your needs.
Suction delivery hose is ideal for pumping up stairs or over obstacles.
