Dirty Water – Vortex Pumps
Dirty water is classified as water that has suspended solids larger than 1mm in diameter or long stringy matter (such as hair) suspended in it.
A normal drainage pump with a standard closed impeller will not be able to handle this. That is why heavy duty, rugged, drainage pumps from ClayTech have been designed to meet almost any need. Made for our harsh Australian conditions.
Recognised for their reliability and performance BlueVort 7 has an open vortex design and can handle pumping soft solids up to 15mm. It has been designed as a multi-purpose submersible pump also suited for drainage and water transfer applications. The BVP is a heavy duty all-purpose, reinforced polypropylene vortex pump. This pump is tough! It has been trialled, and survived, the pumping of debris from construction pits. BlueVort 9 has an open vortex design and can handle pumping soft solids up to 25m min size making it suitable for grey water tank and final pumping from domestic water treatment systems. It has been designed as a multi-purpose submersible pump also suited for drainage and water transfer applications.
