1. The priming tank design is bases on a simple peel valve with double balls. The lower float reduces the intake diameter when the suction hose is fully primed in order to reduce turbulence in the chamber. This prevents any water from going into the vacuum pump.
There is no leverage structure in the priming tank. The peel valve is only a simple rubber, the user can replace it without purchasing from MOTION PUMP.
The priming tank is very light and compact overall. It is very easily disassembled for cleaning or repair. No parts are cast. The priming tank been tighten only by 4 rods. It can be disassembled by one person. The shell of the priming tank is make of stainless steel and the other parts are electrophoresis treated.
2. The TBL ball valve adjusts the water turbulence automatically. The water can be completed blocked out from float ball with peel valve.
