Reduction for a hand pump 50mm with valve

Reduction for 50mm hand pump with INNOVATIVE TWO-WAY VALVE
- Reduction 50 x 30 mm allows you to pump material from hard to reach places,
- in the reduction mounted diaphragm permanently.
- THE DESIGN OF THE VALVE ALLOWS YOU TO HOLD THE MATERIAL IN THE PUMP
 Reduction without a valve requires the rapid return of material from the pipe.
The valve ensures that the material does not fall out!!!
The material is held in the pipe until the piston is pushed, then the material freely falls out of the pipe.
This is a sensational solution, it gives you the comfort of work, without the risk of losing your precious cargo!!!

the reduction is applied to the pump pipe. The element goes quite tight. Can be mounted permanently with a mini screw.
