Comparison of head losses:
air and dirt separator to Y-strainers
Y-strainers entrap dirt within a basket made of stainless steel or brass
mesh, selected for the size of the largest particle. Particles smaller
than the mesh size may pass through. On most Y-strainers, the basket
must be removed periodically to clear the trapped debris. As the debris
collects in the basket, flow is impeded resulting in increasing pressure
drop and therefore higher head loss. The dirt separation function in the
DISCALDIRT
®
performs exactly as it does in the DIRTCAL
®
, utilizing the
low-velocity-zone principle. The flow velocity of fluid flowing into the dirt
separation chamber is greatly reduced causing the entrained dirt par-
ticles to drop due to their density.
The internal element provides surfaces that assist in separating dirt particles
and guide them downward to ultimately settle to the bottom of the
separator. The dirt separator only creates about 25% of the pressure
drop of a comparable sized, clean basket strainer, depending on mesh
size and amount of filtered debris. These head losses are not affected
by the amount of dirt collected.
Replacement parts
Drain valves (5) & (7), code 538402 FD. Drain valves (8), separator sizes
2" - 6", code NA39753; separator sizes 8" -14", code NA59600.
Insulation shells
The brass DISCALDIRT
®
5460 series can be supplied with the optional
insulated cover, code CBN546002 series (purchased separately), to
minimize heat loss.

Removing insulation and
draining impurities
1. Remove the insulation by taking off
the bottom casing of the collection
chamber first, and if necessary, the
top insulation casing later.
3. Flush out the debris by turning the
handle to open the drain valve.
4. When finished, replace the
insulationshells.
