SELF-CLEANING STRAINERS
The installation of a Hydromatic strainer will eliminate the nuisance of unwanted
and untimely system shut-downs. Because Hydromatic can function as a sea chest it
can replace multiple seacocks, strainers and related fittings and hose, thus reducing
the cost of new or retrofit installations.
• A 30-second filter basket cleaning cycle is performed at intervals selected by the
user. The choices are every 5 minutes, 15 minutes, 30 minutes or 60 minutes.
• Macerator grinds and discharges sea grass, jellyfish and debris that commonly
clog ordinary raw water strainers.
• DC motor is submersible
• Operator panel allows you to monitor and adjust system operation.

GROCO
911 / 970 Series
Commercial duty self-cleaning strainers
The HSEF Series is similar in function to the 970 series, but it is intended for
commercial or industrial applications that requires 4”, 5” or 6” plumbing and
have an ac power source. Debris and ice that accumulates within the filter basket
is automatically macerated and discharged through a 1” plumbing line. System
shut-down for filter cleaning is thus eliminated, as is the need for heavier, larger,
and more expensive strainers.
