DESCRIPTION

Telescopic Bellmouths are used extensively in wastewater purification works to draw off surface fluids and scum. A Bellmouth consists of a lower outer tube which is connected to a drain pipe, and an upper inner tube which slides up and down to vary the fluid level as required. Seals are fitted between the inner and outer tubes to prevent leakages. Telescoping valves are also used to regulate fluid levels, either by draining one tank into another or filling an adjacent tank with a higher water level.

Operation is generally manual by means of hand wheel and spindle connected to the inner tube.
