PL modes (PL/PS/PR/RL)
Operating principle: The pressure differential required to
generate fertilizer suction via the Venturis is produced by a
booster pump integrated in the FertiKit
TM
.
These modes of operation, where the lower manifold is under
low pressure (around 0 bars/PSI), permits the use of high-efficiency
Venturis with high suction capacity and low motive flow consumption.
Flow rate: 20 - 700 m³/h (85 - 3000 GPM)
Suitable for main line pressure:
PL
: 2.5 - 6.5 bars (36 - 94 PSI).
PR with PRV
27
: 6.5 - 8.5 bars (94 - 123 PSI)
PS with PSV
26
: Based on cavitation risk.
RL with PRV
27
and PSV
26
: 2.5 - 8.5 bars (36 - 123 PSI)
Dosing channels:
Accommodates a wide variety of dosing channels for fertilizer
and concentrated/diluted acid:
