Speck Porpoise Pool Pump Mechanical Shaft Seal
Speck Porpoise swimming pool pump mechanical shaft seal.
This seal fits on all the 90 series swimming pool pumps 90/10, 90/16 and 90/22.
The mechanical pool pump shaft seal prevents water going through to the electrical motor side of your pool pump and must never be allowed to run without water in the swimming pool pump.
If this should happen the pool pump shaft seal will get hot and get damaged.
