Pressure and suction hoses work with pumps to both efficiently
remove unneeded materials, such as water or chemical buildup, as
well as to transport solid media, such as sand or wood chips.
Suction hoses are used under negative pressure to remove materials,
while pressure hoses operate under positive pressure to discharge
materials. These hoses are made from various polymers, such as
polyvinyl chloride (PVC) and polyurethane (PU). The hose is then
strengthened by a support coil running along the tube. This coil
can be made from a variety of materials, including PVC or steel.
Figure 1 shows a light-green PVC hose with a PVC support coil
running throughout the hose.
