Micro Flood Nozzle Flow Rates
Pressure (kPa)
Multotec’s Flood Nozzle design reduces downtime and ensures constant, efficient operation. Multotec Flood Nozzles are manufactured from abrasion resistant polyurethane, ensuring long life. They replace two or three conventional spray nozzles with one, by utilising a 120 degree spray angle.
The orifice diameter for standard sizes (Heavy Duty 18 mm and 10 mm) facilitates uninterrupted flow by reducing blockage problems from contaminated water.
Mounting
The Flood Nozzle can be mounted horizontally behind the pipe spray, reducing the possibility of damage or loss by positioning the nozzle out of the flow of the screen material.
The Flood Nozzle can be mounted at an angle of up to 45 degrees into the flow to tumble material and to improve screening efficiency

Super Flood Nozzles
The Multotec Super Flood Nozzle has been designed to replace conventional flood boxes.
• No more silting up of the flood boxes - better access to panels• Low pressure, high volume water curtain with no blockages• Available in two sizes - 370 x 645 mm and 250 x 420 mm

Multospray Nozzles are manufactured with a standard thread to fit a BSP 3/4” pipe socket.
• Wet screening• Ore washing• Medium recovery• Slimes removal• Conveyor belt cleaning• Cooling
• Orifices range from 5 mm to 11 mm• Corrosion and wear resistant polyurethane• Operating pressure range up to 4 bar• Uniform water curtain with high operating efficiencies• Standard fittings for easy installations
Quick release adaptors can be used in conjunction with Multospray, allowing for quick and easy installation.
3/8” to 3/4” adaptors can be supplied with the Multospray where existing installations have a BSP 3/8” socket.
Multosprays have many applications including:
