Inner structure: 


1. Adopting external bearing which lubricated individually, so can deliver various medium no matter lubricating or non-lubricating. 
2. Adopting timing gear, there is on metallic contact between rotating parts, so a long service life is ensured. And there is no dangerous even dry running in a short time. 
3. Adopting circular valve, when outlet pressure is higher than working pressure and the circular valve will be open, some medium through the circular valve and come back the inlet of the pump or saving can. At the same time, the twin screw pump work in all pressure for bringing down torque. 
4. When working, drive screws, driven screws form sealed chamber together with the surrounding pump casing, the medium in the sealed chamber is shifted axially and completely continuously from the suction side to delivery side of the pump as the shafts turn. Because the capacity of the seal casing doesn't change in working, the pump transfers liquid without pulsation. 

 

Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff Valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
