Protect Your Pumped Water Systems From Unwanted Sand

LAKOS: Experienced in the waterworks industry
With capabilities for working with engineering firms, private water companies and public agencies, LAKOS has
the expertise for both simple and challenging systems. We know and understand the typical specifications.
We supply the needed documentations. We have the products that meet the demands of this industry.
NSF standards. Low-lead certifications. ASME Code option. Third-party performance testing. Trust
LAKOS for your water system protection needs.
Perhaps you no longer consider the use of filtration, given the downside when applying most of
the common techniques. Downtime, cleaning routines, replacement parts, duplicate hardware and
bypass piping. LAKOS is the unique alternative that you can apply with confidence.

Instead of screens & strainers – A LAKOS Sand Separator removes sand & grit as small as
200 mesh (74 microns) and can handle particle concentrations up to 1,000 parts per million.
• No clogged screens, cleaning routines or excessive replacement parts.
• No downtime or maintenance/servicing routines.
• No backwashing or excessive water loss.
Instead of hydrocyclones – Though similar to LAKOS Sand Separators (employing centrifugal
action for performance), this technology has limited model sizes and typically demands high
pressure loss and a continuous underflow to evacuate solids. Its conical design encourages wear to
the cone, often requiring a replaceable liner. LAKOS, instead, offers a better way.
• Low pressure loss
• Periodic purging for minimal water loss
• No cone or replaceable liner
Increase the life of filter cartridges & membranes – When finer filtration demands
such filters, a LAKOS Sand Separator as a pre-filter can remove the bulk of the larger unwanted
solids, allowing finer filters to perform better and longer.
• Saves on replacements
• Reduces downtime & labor for replacements
• Controls cartridge waste volume

Protect Your Pumped Water
Systems From Unwanted Sand,
Grit & Other Particle Matter
LAKOS: A world leader in filtration
Founded in 1972 by Claude Laval III, LAKOS Separators first earned a reputation by protecting water well
pumps and irrigation systems from abrasive sand. Over time, applications in food processing, HVAC, industrial
processing and municipal water systems expanded the company’s capabilities to a multitude of other
applications, augmented further by the addition of complete filtration packages and state-of-the-art sand
media filtration & self-cleaning pump intake screens. Today, our singular focus on filtration is supported by
technical expertise and solution-oriented customer service.
Continuous operation • Maintenance-free
performance • Minimal water loss
Protect water treatment & sand media filtration – A LAKOS Sand Separator and/or
Pump Intake Screen can keep larger particle matter from fouling such equipment, eliminating vast
amounts of backwash water and keeping make-up water & chemical replenishment to a minimum.
Instead of intake water sieves or stationary screens – A LAKOS Self-Cleaning Pump
Intake Screen continuously cleans the rotating screen and keeps unwanted debris from clogging
or damaging the pump. No debris handling is required because the screen cleaning occurs in the
water source; no debris collection bins or awkward waste-handling routines.
Canal Water Intake
New Zealand
For variable (VFD) & on-demand flows – Instead of suffering the downtime & cleaning of
a large screen filter, two or more LAKOS Separators may be manifolded and combined with pressure
& valve control to accommodate virtually any flow range.

Solving filtration problems throughout your waterworks systems
Water wells
Rivers, canals & open water intakes
Groundwater formations often yield sand. This could be due to
over pumping an aquifer, drought/drawdown or old casings.
Earthquakes and changing aquifer conditions also can occur.
A LAKOS Sand Separator on the pump’s discharge is a great
solution. Alternatively, a LAKOS Pump Protection Separator can
keep troublesome sand from prematurely wearing a pump to low
efficiency. Reduced pump repairs/replacements and increased
energy efficiency for reduced costs overall.
Pumping from open water sources often draws unwanted particle
matter into the pump and the water system. Sand & silt are
common in moving water, especially at higher flows and/or after
Pressure gauges
rainstorms. Pumps suffer damage & lost efficiency,
increasing

maintenance and energy costs. Static screens become
clogged,
to monitor proper

requiring maintenance & cleaning routines. Instead,
LAKOS SelfCleaning Pump Intake Screens keep such debris & particle matter
from being drawn into the pump, thereby protecting both the
pump and the downstream equipment fed by the pump.
Inlet 1
Landscape irrigation
Parks, road medians and other greenbelts are typically irrigated
with automated sprinkler systems. If sand gets into the automatic
valves, that can cause the valves to fail in the open or closed
position, thereby overwatering the landscape (flooding & wasting
water) or underwatering (killing the plants). Similarly, spray nozzles
can become worn (overwatering) or clogged (underwatering).
This puts a burden on maintenance operations to inspect & service
the irrigation systems and may result in excessive parts or plants
replacements at added expense.

LAKOS for your water system protection needs.
Perhaps you no longer consider the use of filtration, given the downside when applying most of
the common techniques. Downtime, cleaning routines, replacement parts, duplicate hardware and
bypass piping. LAKOS is the unique alternative that you can apply with confidence.

Instead of screens & strainers – A LAKOS Sand Separator removes sand & grit as small as
200 mesh (74 microns) and can handle particle concentrations up to 1,000 parts per million.
• No clogged screens, cleaning routines or excessive replacement parts.
• No downtime or maintenance/servicing routines.
• No backwashing or excessive water loss.
Instead of hydrocyclones – Though similar to LAKOS Sand Separators (employing centrifugal
action for performance), this technology has limited model sizes and typically demands high
pressure loss and a continuous underflow to evacuate solids. Its conical design encourages wear to
the cone, often requiring a replaceable liner. LAKOS, instead, offers a better way.
• Low pressure loss
• Periodic purging for minimal water loss
• No cone or replaceable liner
Increase the life of filter cartridges & membranes – When finer filtration demands
such filters, a LAKOS Sand Separator as a pre-filter can remove the bulk of the larger unwanted
solids, allowing finer filters to perform better and longer.
• Saves on replacements
• Reduces downtime & labor for replacements
• Controls cartridge waste volume

Protect Your Pumped Water
Systems From Unwanted Sand,
Grit & Other Particle Matter
LAKOS: A world leader in filtration
Founded in 1972 by Claude Laval III, LAKOS Separators first earned a reputation by protecting water well
pumps and irrigation systems from abrasive sand. Over time, applications in food processing, HVAC, industrial
processing and municipal water systems expanded the company’s capabilities to a multitude of other
applications, augmented further by the addition of complete filtration packages and state-of-the-art sand
media filtration & self-cleaning pump intake screens. Today, our singular focus on filtration is supported by
technical expertise and solution-oriented customer service.
Continuous operation • Maintenance-free
performance • Minimal water loss
Protect water treatment & sand media filtration – A LAKOS Sand Separator and/or
Pump Intake Screen can keep larger particle matter from fouling such equipment, eliminating vast
amounts of backwash water and keeping make-up water & chemical replenishment to a minimum.
Instead of intake water sieves or stationary screens – A LAKOS Self-Cleaning Pump
Intake Screen continuously cleans the rotating screen and keeps unwanted debris from clogging
or damaging the pump. No debris handling is required because the screen cleaning occurs in the
water source; no debris collection bins or awkward waste-handling routines.

For variable (VFD) & on-demand flows – Instead of suffering the downtime & cleaning of
a large screen filter, two or more LAKOS Separators may be manifolded and combined with pressure
& valve control to accommodate virtually any flow range.
