Sea Recovery Ultra Whisper Rev. A
6. Feed Pump supplies a
positive pressure
through the
Prefiltration [7, 13, &
14], and into the
Energy Transfer
Device [17] (ETD).
The Feed Pump Flow and Pressure causes the
ETD [17] to function.
7. Plankton Filter *** This filter
assembly contains a cleanable ultra
fine monel mesh screen. The mesh
screen removes suspended solids or
biological growth such as plankton
and provides reduced maintenance
costs and longer life to the Pre-
filter Elements [13 & 14].
8. Inline Pressure Pick-Up Tee
for delivers line pressure to the
low pressure manifold [9].
9. Low Pressure Manifold
connects the Feed Pump
outlet pressure to the Low
Pressure Switch [10], the
High Pressure Switch [11],
and the Prefilter Inlet
Pressure Gauge [12].
10. Low Pressure Switch (see illustration above) shuts
the System off automatically when the Feed
Pump fails or when the suction line prior to the
Feed Pump Inlet becomes blocked causing an
abnormal vacuum to the Feed Pump Inlet.
The Low Pressure Switch is a Normally Open
Switch that Closes at or above 40 PSI to keep the
System in operation. The Low Pressure Switch is
attached to the Compact Frame or the Modular
Prefilter bracket.
11. High Pressure Switch (see illustration above) is a
safety device that stops the system if the Feed
Pump outlet pressure exceeds 190 PSI. The High
Pressure Switch is a Normally Closed Switch that
Opens at 190 PSI to shut the system off. The Low
Pressure Switch is attached to the Compact Frame
or the Modular Prefilter bracket.

Control Panel and monitors the pressure from the
Outlet of the Feed Pump [6] entering the Inlet of
the Prefiltration [13]. This Gauge is used along
with the Prefilter Outlet Gauge [16] to determine
the condition of the Prefilter Elements.

13. Pre-Filter 25 mμ This filter removes suspended
solids 25 Microns and larger to prolong the life of
the final 5 Micron Prefilter.[14] element.
14. Pre-Filter 5 mμ This filter removes suspended
solids 5 Microns and larger to prolong the life of
and protect the Reverse Osmosis Membrane [20]
from fouling.
WARNING: Do not use third party prefilter
elements, use only Sea Recovery Prefilter
Elements. Third party prefilter elements on the
market do not properly fit, the seams fall apart
resulting in damage to the ETD, and they will
allow by-pass resulting in premature fouling of the
R.O. Membrane Element.
CAUTION: Do not use "string wound" or "fiber"
prefilter elements. These type of elements are
designed for the Photographic Film Developing
industry. When used in sea water they will plug
up rapidly in 1/10th or less the time causing
frequent shut down of the system and very
frequent changing resulting in very high cost of
maintenance.
