Replacing submersible pump-best company/model?

[berriman]

My first pump lasted 10 years. In the past 4 years, I have had to replace my pond pump twice. Once due to total pump failure and once due to electrical issue (keeps triggering GFCI). I have always selected a pump that met the specs for my pond (total pond approximately 5000 gallons, Head Pressure approximately 18, spillway 3000 gph).

I am currently looking at:
--Tsurumi 8PM
--Tidalwave A21
--Aquascape Pro 7500
--Easypro TH 7502
--Shinmaywa 50CR2.75S

However, I need some expert advice on reliability. I am tired of replacing this pump.

Late reply. I have always have good results with Easy Pro.
