I use it for a closed loop for a 265. Excellent flow for a closed loop, as long as there is not a lot of head loss.
I think Sequence has lowered the price of their pumps, but also lowered the quality. Most of my Sequence pumps have tiny leaks in the seals, which leaves salt creep in the motor assembly. The leaks are slow, so the ground does not get wet. Just salt creep down the shaft near the seals.
My older Sequence pump ran for 5 years with no leaks and the plastic used on the head was much stronger. I snapped the threads on my newest Barracuda by tightening it too much.
Just my experience. I currently run 9 Sequence pumps in different applications.
