2. Hard suction hose - Wikipedia

   en.wikipedia.org/wiki/Hard_suction_hose

   Flexible suction hose, also known as a suction hose, is a specific type of rigid fire hose used in drafting operations. When using this technique, the fire engine draws water for fire fighting from an unpressurized supply, such as a portable water tank, pool, or other static water source, instead of drawing water from a pressurized water supply, such as a fire hydrant.

   Suction hose A large, semi-flexible and non collapsible hose used to move water from a static source such as a pond, pool or storage tank to a fire pump by means of suction. The whole process is often known as "drafting". Should not be used to connect pressurized hydrants to pumps. Sunila tool

4. Draft (water) - Wikipedia

   en.wikipedia.org/wiki/Draft_(water)

   A rural fire department or farmer might draft water from a pond as the first step in moving the water elsewhere. A suction pump creates a partial vacuum (a "draft") and the atmospheric pressure on the water's surface forces the water into the pump, usually via a rigid pipe (sometimes called a dry hydrant) or a semi-rigid hard suction hose.

   Attack hose is a fabric-covered, flexible hose used to bring water from the fire pumper to the nozzle. This hose ranges in nominal inside diameter from 1.5 to 3 in (38 to 76 mm) and is designed to operate at pressures up to about 400 psi (2,760 kPa). The standard length is 50 ft (15.24 m).

6. Peristaltic pump - Wikipedia

   en.wikipedia.org/wiki/Peristaltic_pump

   This class of pump is often called a "hose pump". The biggest advantage with the hose pumps over the roller pumps is the high operating pressure of up to 16 bar. With rollers, max pressure can arrive up to 12 bar (170 psi) without any problem. If the high operating pressure is not required, a tubing pump is a better option than a hose pump if ...
