I think they are 1/2 HP, plastic 2900-3500?
I'm not sure, they aren't anything special around $100.00
Get the 1 1/2 to 2 inch threaded nipple from your distributor. It threads into the discharge of the pump and then you set for 2-inch hose.
Years ago we bought a gas fired trash pump but didn't use it enough, when we did need it we couldn't get it started. :x
After that we just rented, the rental store has bigger if needed and theirs always runs. :wink:
