Suction hose usually 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, but mostly PVC. The hose is then strengthened by a support coil running along the tube. This coil is made from PVC mostly as well.
