DIFFERENTIAL PRESSURE INDICATORS
- Mounts
directly to the strainer body and visually indicates when the baskets require
cleaning. Preset at a differential pressure of 10 PSI with an option for
settings of 5 and 15 PSI.
DIN ELECTRICAL PROBES
(32k
PDF files) - For use with the above
differential pressure indicator. Provides an electrical signal when the pre-set
maximum differential pressure is reached.
BASKETS - Screens available in sizes ranging from 300 mesh to 1/4"
perforations.
MAGNETIC INSERTS - Mounted to the strainer baskets to collect metallic
particles.
100% SHUT-OFF - Achieved through the use of special seals within the
change-over mechanism to eliminate leakage between chambers.
AIR ELIMINATORS - Automatically vents air from basket chambers. (ex.
After basket cleaning).
MOUNTING STUDS / BRACKETS - Allowing the strainer to be independently
supported.
HEATING JACKETS - Used to maintain the temperature of the process fluid
inside the strainer. Mounted permanently to the strainer body allowing a supply
of steam or hot water to pass around the body.
PRESSURE EQUALIZING VALVES - Standard on the 5, 6, and 8 IN. strainers,
these may be fitted to other sizes upon request.
SPECIAL SEALING MATERIALS - EPDM, PTFE, Viton. Others upon request.
BODY AND INTERNALS - Available in other material combinations, consult
