4G INSTALLATION MANUAL
DESCRIPTION
BP PL mode
Bypass system for pressurized-line water source.
Operating principle:
The pressure differential required to generate fertilizer suction via the Venturis
is produced by a booster pump integrated in the NetaJet™ 4G. This mode of
operation, where the lower manifold is under low pressure (around 0 bar/PSI),
permits the use of high-efficiency Venturis with high suction capacity and low
motive flow consumption.
Suitable for main line flow rate:
20-120 m³/h (90-500 GPM)
Flow limitation depends on the fertilizer injection rate and the size of the Venturis.
Suitable for main line pressure:
• Standard: 2.5-5.8 bar (36.5-84.0 PSI)
• High pressure: 5.8-7.5 bar (84.0-108.5 PSI)
For main line pressures lower than 2.5 bar (36.5 PSI), consult Netafim™.
Dosing channels:
Accommodates a wide variety of highly accurate dosing channels for fertilizer and concentrated/diluted acid:
• Up to 5 dosing channels of various types, from 50 l/hr (13 GPH) up to 600 l/hr (158 GPH) each.
• Optional - Concentrated acid channel, 50 l/h (13 GPH)
.
Total fertilizer/acid suction capacity - up to 3000 l/h (792 GPH).
Controller:
NMC-Pro (Operation with third-party controllers is optional. Consult Netafim™.)
EC/pH:
Precise single or dual monitoring and control - selectable by customer.
