I want to upgrade from a otp3000nw to a bubble blaster 3000. This is hooked uo to a DNW2000.

Can this be done and what is needed?

Thanks

No, it cannot be done. You can only upgrade to the HY3000S pump if you have the OTP3000GT pump. OTP-GT pumps have a larger output than the NW pumps. Reducing the output of the HY3000S pump would defeat the purpose of having the larger pump.

Yes, the larger adapter on the Aquatrance pump can be removed.

Lou, I apologize for this. You cannot upgrade to a larger pump if your skimmer has the older OTP3000NW pump. I just double checked with a fellow rep who has been here longer and he just corrected me.

I am sorry about the mistake. Unfortunately you cannot upgrade your skimmer to a different pump if your skimmer came with an NW type of OTP pump.

Please use the "Submit a Ticket" option on the right and I may be able to offer you another option.

We do not have any other pump, except for the OTP3000NW that will fit the skimmer you have. The OTP3000NW adapter has been discontinued for years and no skimmer is now made with that size input.

I said as a input pump not a recirculating pump....so air going in the input and the air from the recirculating pump.

The question is this/ too much air for the body. (2 otp300 one feeding / one recirculating ....2 x 770 cfm = 14000cfm)

In terms of the feeding pump, as long as you use a pump that does not exceed 790 gph, you will be fine. 790 gph is the max amount of water the skimmer can handle without overflowing. More than that and you will be pushing in more water than the skimmer to push out.

For this skimmer, we would recommend 1 to 1.5 times the system volute BUT not exceeding 790 gph.
