Slurrpy Venturi Sand Pump

The SLURRPY pump is a water-operated venturi pump which can be operated by a garden hose or conventional mechanical pump to be able to pump solids, liquid and air, or all three at once.

The operating jet water mixes with, and goes out with, the waste that is being pumped. The garden hose (No.2) model pumps, which click onto a garden hose, will pump up to 70 litres per minute on an average tap pressure, and solids and stone up to 9mm in diameter. The model No.7 bore sinking pump operates from any high pressure pump such as a fire-fighting pump, and will pump approximately 450 litres per minute or more (depending on the horsepower of the fire-fighting pump), and pump solids and stones up to 31mm. in diameter.

How the SLURRPY Pump works

The pump body is fitted with a stainless steel or polyester venturi sleeve. A venturi is similar to two aeroplane wings which have been inverted and this shape is formed into a round tube. When high speed water or air from the pump jet is passed over the airfoil shape, it creates a low pressure (or vacuum) at the throat. The surrounding atmospheric pressure then pushes the waste water, sand, gravel, air, etc, into the venturi sleeve. The length, shape and diameter of this sleeve in relationship to the diameter of the high speed water jet, plus the pressure of the jet stream, determine how high it will support the column of waste water.

The flow rate is determined by the diameter and is varied by the height of the column of waste and the resistance caused by diameter and/or length of the pipe or hose being used to transport the waste - the high pressure jet water mixes with, and goes out with, the waste. With a 25mm discharge hose about 3m long attached to the pump it will work on a ratio of approximately 4 to 1 at a one metre head when operated with a water supply pressure of 550kPa at the pump and will use about 16.6 litres per minute from the garden hose supply. It will pump approx-imately 60 to 70 litres/minute of waste. With 50mm. discharge about 80L/min.
