Need to replace a little giant 4-MDQ-SC

[bbehring]

I have 3 pumps which are all little Giant 4-MDQ-SC will need to be replaced. All are plumbed outside the sump, under the tank, within the stand, with bulkheads through the base front side of the sump. Although these pumps have stood the test of time (14 years) (1 - supply from the sump to the chiller and returned to the tank; 1 - supply from the sump to the tank (recirc flow only; and 1 - supply from sump through ocean clear filter and back to tank). Recommendations appreciated.

If I was replacing them, I would replace them with GenX mak 4 pumps. They have very similar flow rates, the plumbing is a little different 3/4 in and out verses the 1 inch in and 1/2 out. But they are quieter, and use less electricity. They are pretty close to the same price also.

Are you looking for a didderent brand of pump? Why? Don't think you could ask for better.
