Head Loss: Typically, 9-14 feet (2.74-4.27m), except models with optional tail pipes, which will experience a notably greater head
loss. Consult factory for details.
Maximum Particle Size: 1/4 inch (6.3mm)
Maximum Particle Concentration: 1,000 ppm
*Optional tail pipe in place of the flapper valve

Pump Protection Separators Installation Guide
Flapper Valve Open
Sand discharges
deep into well.
Sand is
centrifugally
separated from
water and tossed
to perimeter
of chamber.
Flapper Valve Closed
Sand accumulates
in separator.
Sandy water is
drawn through
tangential inlet
slots into
separation
chamber.
Sand-free water
is drawn to
center of
separator and up
through vortex
outlet to pump’s
suction.
Sand particles
fall downward,
along perimeter,
to bottom
of separator.

IMPORTANT:
Separator models with
single-letter designations
(i.e. D, E, F, etc.) require a
minimum submergence of
30 ft (9.2m) below the
drawdown water level.
Models with three-letter
designations require 60 ft
(18.3m) submergence.
Minimum clearance below
separator’s purge discharge:
30 ft (9.2m)
