Bought this Recently. Model 1.9 Item# 40120 115 VAC 60 Hz, 19 watts, 0.3 Amps. Dimensions 3-7/16” L x 2-1/8” W x 3-5/16” H, “includes the Threaded output.“ 180 GPH @ 1ft. 160 GPH @ 2ft. 140 GPH @ 3ft 130 GPH @ 4ft. Shutoff appears to be at 6.5ft. Inlet 3/8” MPT, Outlet 1/4” MPT. Without using an adapter a 1/2” ID Hose will fit over this fitting secured with a Vinyl Plastic Ratchet Clamp, available from ACE Hardware. Pump came with a Strainer Cover, a thin Foam filter inside the cover, more for protecting the pump, than Biological. Also has a non-removable volume valve on the pump outlet. Pump is Quiet enough I can’t hear it running** Puts out a good volume of water, but I did not measure the output. My other Danner pumps, put out the rated volumes, or slightly above when measured. All Parts are available, for this pump, and they do have accessory filters. They appear to be more suited for ponds. For Extra filtration, I’d recommend adapting someone else’s sponge filter, to the inlet. ** When I first started the pump, it had a rattle due to trapped air in the pump.
