How to select the Keller Separator for your application:A Keller portable separator can clean a sump in 3 to 4 hours, and then may be moved to another sump and set up in minutes. We recommend that each sump be cleaned once per week. A separator can clean two sumps in a single shift, or 10 sumps per week in a one shift 5 day operation.
The separator model is selected based on:
the sizes of
sumps to be cleaned,
the relative
volume of tramp oil to be removed, and
the quantity
of suspended solids in the sumps.

How the Keller Separators Work:Each separator is supplied with three inlet devices (see below) which can access the surface of any sump through
an opening as small as 3" diameter. The self-priming air operated pump pulls the tramp oil/coolant mixture from
the surface of the sump via the inlet device, then through a high capacity bag filter, which removes chips from the
fluid. The oil/coolant mixture is then pumped through the patented Keller all-plastic separator elements immersed
in a separator tank. The cleaned coolant continuously returns to the sump. The oil layer collected on top of the
separator tank can be drained into a waste oil container by opening the oil drain valve occasionally, usually once
per day. No other operator attention is required.
Inlet Devices 
An inlet device draws in oily coolant from the surface of the sump
while avoiding the intake of air, which can interfere with splitting of
oil from coolant in the separator tank. One inlet device is used in
each sump. The #555-07 Floating Inlet Device (7" wide x 10" long),
the most frequently used inlet device, automatically compensates for
any changes in the level of coolant in the sump. The #555-07 may
be used in pit-type sumps with liquid levels as much as 10 feet below
floor level. The #555-05 Floating Inlet Device (2" wide x 12" long) is
used when only a narrow access space is available; for example,
next to a conveyor. The #555-06 Fixed Inlet Device requires only a
3" diameter hole for access to the sump but must be adjusted
manually if the sump level changes significantly.
Since a Keller portable separator is to be rotated among several
machines in sequence, it is most convenient to mount an inlet device
permanently in each sump, rather than moving one inlet device from
sump to sump. The connection from the inlet device to the separator
is a quick connect garden hose fitting.See
below for listing of inlet devices supplied with each unit
