Description

H. MONITOR - VARUN 643 BZ (STAINLESS STEEL)
H. MONITOR – VARUN 643 BZ (STAINLESS STEEL)

Corrosion resistant stainless steel monitor Model VARUN 643 BZ is durable manual controlled low profile monitor for fixed installation as well as trailer mounted unit. The monitor is generally used for protection of flammable liquid storage tanks, loading racks, dykes marine and many other Industrial applications. The Monitor possess several design features that provides ease of operation, minimum maintenance and resistance to normally destructive environments. The monitor is used with aspirating, non-aspirating and water nozzles with flow range upto 3300 GPM (12500 LPM).
The monitor has welded stainless steel 6 inch (150 MM) water way. The vertical and horizontal rotation is through bronze swiveling joints with double row of stainless steel ball bearing. Both vertical and  horizontal movements are controlled with handwheel driven fully enclosed worm gear.
The monitor has large flow capability and can be manually operated by a single fire fighter. The design ensures to prevent jet reaction forces from effecting the horizontal and vertical position of the monitor. The monitor has the ability for 360 deg. continuous horizontal rotation and angle of elevation is adjustable with fix stop from 90 deg. above horizontal to 65 deg. below horizontal. The water vanes in discharge tube reduces the
turbulence and friction loss, thus increasing the nozzle performance to achieve greater range. To ensure desired performance, the friction loss through
monitor must be considered while selecting the nozzle and the flow through the monitor with reference to available base pressure at inlet of the monitor. For flow and jet reach data refer monitor nozzle data sheet.
