Pump Protection Separators

Installation Guide

LAKOS Pump Protection Separators come in a variety of
sizes. They can be used with either turbine pumps or large
submersible pumps. They may be shipped in a variety of ways.
Most often, each unit is strapped onto a wooden skid. Before
installation, remove all labels, decals and shipping instructions
from each unit to avoid plugging the inlet slots. LAKOS Pump
Protection Separators are designed to continuously ush
separated particles back into the source water.

For Turbine pumps:

LAKOS Turbine Separators are manufactured with a standard
M.N.P.T. riser (note General Specications chart on next
page). Should this riser not match the connection to your
pump’s bowl assembly, you’ll need to arrange for the proper
connection (i.e. reducer, etc.). Lifting lugs are provided on the
riser of all models size “E” through “K” for ease of installation.
Connect the separator to the bowl assembly, then install
the apper valve as shown on page 3. At this point, you may

proceed with your customary routine for installing the pump.

FOR

SUBMERSIBLE

PUMPS

For Submersible pumps:

To allow LAKOS Pump Protection Separators to remove sand
prior to the pump intake, the water must rst be directed
to rst pass through the separator. To achieve this with a
submersible pump, LAKOS provides a pump enclosure shell
or shell kit (see page 4). The submersible pump is positioned
within this shell and then attached directly to the separator
outlet. With the pump properly secured in the shell, the riser
is now attached directly to the column pipe. Installation may

now proceed as normal for submersible pumps.

Once installed, LAKOS Pump Protection Separators require
no routine maintenance. Should you ever need to pull your
pump, always take the opportunity to inspect the separator
and purge assembly.

Sand is
centrifugally
separated from
water and tossed
to perimeter
of chamber.

Flapper Valve Closed
Sand accumulates
in separator.

Flapper Valve Open
Sand discharges
deep into well.

Sandy water is
drawn through
tangential inlet
slots into

chamber.

Sand-free water
is drawn to
center of
separator and up
through vortex
outlet to pump’s
suction.

Sand particles
fall downward,

single-letter designations

(i.e. D, E, F, etc.) require a

minimum submergence of
