Siv 611 Single gear operated fixed monitor

Description

Siv 611 is a 3” monitor for fixed installations made of corrosion resistant bronze, with an unobstructed 3” waterway for low friction loss and high flow. Ideal for marine, offshore, industrial or other corrosive environments. It is suitable for water and foam applications both onshore and offshore. It has been approved by Lloyds register for marine use. The construction include vertical movement by worm gear that is fully enclosed from the elements. Bearings and other fittings which are vital for the correct functions, are made in stainless steel. Cast-in turning vanes for efficient flow up to 4,800lpm ,minimizes turbulence and frictional pressure losses. It has grease fittings for lubrication.

Accessories

  • Uller nozzles 1,000 to 4,800 lpm
  • Frigg aspirated foam branchpipe in stainless steel up to 4,000 lpm, with or without self-induction
  • Borghild self-oscillating unit.
  • For further information see our nozzle data sheets.

Operation

The monitor should be connected to the flange. Than the elevation, should be pre-adjusted. When the water arrives to the monitor the settings can be manually adjusted both vertical and horizontal.

Option

If used with Borghild self-oscillating unit, the monitor wil start oscillating according to the pre-settings of the Borghild oscillating unit Borghild oscillating unit can also release the oscillating function during operation and manually direct the stream.
