What are the 1.2 in the picture? Is it the exhaust port?
1 is the water injection port, 2 is the pump bearing oil port! Yours is a sewage lift pump.
Self-priming pump 1, filling hole 2, oil filling hole
1 is the exhaust hole of the filling pump. It is recommended to install 1/2 of the 316 stainless steel ball valve to facilitate the use of exhaust during operation. 2 is the filling hole for filling the pump bearing box with lubricating oil. This is a horizontal single-machine self-priming centrifugal pump, which belongs to the category of cantilever pumps and self-priming pumps.
You’re welcome, thumbs up for you who are studious and eager to ask questions
It is a self-priming pump, but the design of the pump body is fierce and the volume is a bit large. Port 1 is the water filling port before starting for the first time, and port 2 is the oil filling port of the bearing box.
