Self-cleaning Stainless Steel Water Intake Screens

KleenScreen Orbitor

Self Cleaning Intake Screens to protect pumps and systems from organic and inorganic debris.

Benefits

Energy Saving

With a small portion (1.8% - 3.75%) of pumped water backwashing and rotating the screen, it is continuously
cleaned.

This maintains the pumping efficiency of the system at optimum, thereby reducing power consumption.

Repairs and Maintenance

The small screen holes (20 mesh 0.9mm, 30 mesh 0.56mm), filter water entering system. This can
significantly reduce the wear on pump and other system components.

Labour Saving

By reducing major causes of water supply problems, ie screen blockage, loss of prime, and wear on pump the labour required to maintain the system is reduced significantly.

Durable

Stainless steel and thermoplastic components ensure rugged construction and long operational life.

Environmentally Friendly

Satisfies Environmental Council requirements for screen hole size, and intake velocity.

Components

Components Diagram

Uniformity Baffle

This baffle ensures uniform intake velocity across the screen. by stopping any hotspots of high velocity occurring. These hotspots can cause a buildup of debris and the entrapment of fish.

No electrolysis

All materials are stainless steel or plastic, which prevents a corrosive situation with dissimilar metals. The gasket and bolt bushes ensure there is no contact with the intake pipe.

Servicability

The screen can be easily serviced, no tools are required to remove the screen cage for internal maintenance.

Standard connection

The flanges have standard AS 2129 Table E hole dimensions.

Specification Table

Installation Notes:

  • The KleenScreen must be able to rotate.
    Sufficient clearance (100mm) under the screen is required.
  • At least 50mm is required between water surface and top of screen.
  • The recommended position in a stream/river,isto have a 90º bend at end of intake pipe, with the screen facing downstream.The backwash nozzles should be facing the opposite bank of the stream, at a 45º angle up from horizontal. This is the most effective position to flush any debris away from the screen.
  • A screen retrieval system is required to lift the screen out of the water for servicing, and periods of inactivity.
  • It is recommended to lift the screen out of the water when not in use. This prevents the build up of silt and trash around the screen and the growth of algae on the screen.
  • The KS Universal Joint is recommended to provide the flexibility to lift the intake pipe and swing it around to the bank.
  • The backwash line should be plumbed into the discharge of the pump before the valve.
  • The recommended pressure range for backwashing is 40-60 m (60 – 90 psi). If pressure is below this a booster pump is required, or if above a pressure reducing valve.
  • An inline filter with 16 mesh (1.2mm) is required on the backwash line.
