Description

B. MONITOR - VAJRA 433 (CAST BRONZE)
B. MONITOR – VAJRA 433 (CAST BRONZE)

 

Corrosion Resistant Bronze Monitor Model-VAJRA 433, is durable manual controlled 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 application.
The monitor possess several design features that provides ease of operation, minimum maintenance and  resistance to corrosive environments. The monitor is used with aspirating, non-aspirating and water nozzles with flow range upto 2000 GPM (7570 LPM). The monitor has rugged, corrosion resistant cast bronze construction. The vertical and horizontal rotation is through corrosion resistant bronze swivel joints with double row of stainless steel ball bearing. Both vertical and horizontal movements are controlled with handwheel driven fully enclosed worm gears and protected from the elements. 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 the vertical position of the monitor. The counter balance is not required to offset the weight of the nozzle. The monitor has the ability for 360 deg. continuous horizontal rotation and angle of elevation is 90 deg. above horizontal and 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.
Note: (i) Pressure Gauge is optional supply
(ii) *For flow, refer VARSHA-50 FM approved
nozzle Data Sheet No. HD173
