Venturi Sludge Extractor Heads. Turns a pressure washer in to a high volume discharge pump. Water flows through the high pressure nozzle creating a powerful venturi suction that vacuums up dirt, sand, algae, sludge and even stones up to a diameter of 20mm.

The sludge pump is particularly suitable for removing water from basements, gulleys, construction sites or ponds. Its tremendous flexibility also makes it ideal for emptying poorly accessible tanks or catch basins with small inspection openings.
