Flow Characteristics Of Masterstream 1250; Flow Characteristics Of Masterstream 2000 & Masterstream 4000 - Task Force Tips MASTERSTREAM Series Instructions For Safe Operation And Maintenance

3.1 FLOW CHARACTERISTICS OF MASTERSTREAM 1250

Within its flow range, the Masterstream 1250 automatic nozzles operate at the nominal pressure of 100 PSI (7 BAR, 700 KPA).
Figures 2 shows typical performance of this nozzle.
WARNING
An inadequate supply of nozzle
pressure and/or flow will cause
an ineffective stream and can
result in injury, death or loss of
property.
3.2 FLOW CHARACTERISTICS OF MASTERSTREAM 2000 and MASTERSTREAM 4000
The Masterstream 2000 and 4000's
nozzle pressure is user adjustable
from 80 to 120 PSI (5.5-8.3 BAR,
5 5 0 - 8 3 0 K P A ) . P r e s s u r e
adjustment is made by turning a
knob, on the front of the nozzle, to
the desired pressure setting. The
Masterstream 2000 will operate at
the set pressure anywhere within its
flow range of 300 to 2000 GPM
(1100 to 7600 LPM). Figure 3A
shows typical performance of the
Masterstream 2000 nozzle. The
Masterstream 4000 will operate at
the set pressure anywhere within its
flow range of 600 to 4000 GPM
(2300-15000 LPM). Figure 3B
shows typical performance of the
Masterstream 4000 nozzle.
