911 & 970 Series
Hydromatic® Self-Cleaning Strainers
US PATENT NO. 5,830,366

For as long as raw water strainers have been made, and as long as they perform their intended function, they become clogged with sea grass or jellyfish, become excessively restrictive, and require system shutdown for filter basket maitnenance and cleaning.

The installation of a Hydromatic® strainer will eliminate the nuisance of unwanted and untimely system shut-downs, and because Hydromatic® can function as a sea-chest it can replace multiple seacocks, traditional strainers, thru-hull fittings and related plumbing, thus reducing the cost of new or retrofit installations.

A 30-second filter basket cleaning cycle is automatically performed at intervals selected by the user.
Purge option overrides selected cleaning interval.
A macerator grinds and discharges accumulated debris overboard.
“Ignition Protected” permanent magnet motor is submersible.
Installation may be horizontal or vertical (flooded inlet is required).

911-1000 Series is intended to provide filtered water to a single-consumer (air conditioning system, for example). It has 1” NPT ports for raw water-in, filtered water-out and macerated debris discharge.
970-1500 Series is intended to provide filtered water to multiple consumers (multi-unit air conditioner system vessels, for example). It has a 1-1/2” NPT inlet and one 1/2” and two 3/4” NPT outlets, and a 3/4” macerated debris discharge.
970-1515 and 970-2020 Series are intended to provide filtered water to a single large consumer (a main engine, for example). Each has the same NPT size raw water inlet as filtered water outlet, and a 3/4” NPT macerated debris discharge.
