With its powerful macerator, Groco’s Hydromatic strainers eliminate inconvenient shut-downs when the basket becomes blocked with debris. There is no need in shutting down the connecting device as debris is automatically pumped overboard. See the chart below to determine which Hydromatic strainer is right for you. Select 12 or 24 Volts.
Provides filtered water to a single 1-1/2″ or 2″ device. Debris is pumped out through a 3/4″ NPT port.
Details:
• 30-second cleaning cycle automatically operates at user-selected intervals.
• Optional interface begins cleaning cycle when the flow is reduced.
• Powerful macerator grinds debris and expels it overboard below the waterline.
• Can be installed horizontal or vertical (flooded inlet required)
• Submersible
• C84400 bronze construction
• UPC-A: 12v -742985138087

“Extensive bio-fouling of titanium has been observed after only 800 hours of immersion in sea water. This is because titanium has no toxicity towards marine organism; it is an environmentally friendly alloy…”
“In applications where flow velocities need to be less than 8 ft/sec (2.4 m/sec), it is recommended that chlorine be added to the system. Chlorine has been found to be very effective and as little as 0.5 parts per million can successfully maintain a thermally clean system and prevent hard fouling organisms…”
“Titanium is a very noble metal. When coupled to other metals, titanium will be the cathode and the other metal will be the anode and corrode. This galvanic effect may create excessive hydrogen and be absorbed by the titanium, which is a concern because the material can become brittle and eventually break. If dissimilar metals have to be coupled, it is best to utilize insulation products.”

Variable speed units are indeed more efficient and will save you about twenty bucks a month in electricity, however they are a LOT more complex, have many more printed circuit boards and are considerably more expensive to buy. The “boards” may be free with some manufacturers, but the service calls are not $$$$.
VFDs will reduce/eliminate the start up surge & flickering TVs and you can control the speed of the compressor, so most of the benefits of variable speed units are reaped with a very reliable, time tested and relatively inexpensive over the counter VFD controller. If you have single phase 220 our VFD units will have three phase compressors in addition to the VFD, so the surcharge is relatively small.
