Reef Octopus BH-2000 Skimmer Question

[wil-yuhm]

Few days ago I purchased a used BH-2000. The pump varies physically and appears more bulkier than current model BH-2000 listed/offered. Last night the pump after two days of operation was noticeably louder/vibrating. This morning I disassembled the pump and found debris in the pinwheel impeller. Cleaned up the impeller assembly reinstalled and the noise/vibration ceased. My question is whether older BH-2000 models used different pumps and if parts/impellers offered are different between 2000 and 2000s? The pump model number on the casing, "2000" whereas I observe current replacement pump and impeller assemblies are "Aquatrance 2000S." If anyone could clarify whether later Aquatrance 2000S pumps are direct replacement for the larger older style pump/motor protein skimmer housing/plumbing and whether impellers offered for the Aquatrance 2000S can be used as direct replacement for the "2000" BH-2000 pump?

I have no need for an impeller or pump at this time but the information might be helpful should the pump/impeller fail in the future rather than waiting then for any helpful answer.
Thanks!
W.T.

hi, do not think impellers are same ??
on your older model pump, normally just broken ceramic shaft is impeller problem .
can be a lil finicky to start, prime well.

I do not know :)

The old motors look more "heavy duty."

I was curious if I had to replace the pump for a newer aged model Aquatrance 2000S whether complete assembly might be direct replacement?

Of course I'd rather purchase a simple impeller for the older style pump if available and less expensive.

I do not have a newer Aquatrance 2000S impeller to compare. Suppose I could order an impeller and compare and if not the same return for a refund.
