Kerrick's Venturi Sludge Pump attaches to pressure washers turning them into an output pump. Water flows through the high pressure nozzle creating a powerful venturi suction that vacuums up liquids and slurry.
Liquids are vacuumed up at a flow rate of approximately 1:11 for example using 2 l/min will produce and output of 22 l/min. This system is small compact and easy to use, not to mention highly cost effective, making it ideal for use emptying animals troughs, flood clean ups, pools and car wash pits.
A video demonstration of the system sucking up water and then pumping it back into the same trough can be seen below:
