Drywall taping and texture system using bladder pump with pneumatic flip/flop logic remote control

摘要: A drywall tape and texture system for pumping fluid material from a container to work surface includes pump housing, compressed air supply, plurality of release mechanisms, an inflatable bladder mounted within the housing held between upper lower valves controlling flow material. The may be fully or partially immersed into filled with An automatic pneumatic pressure relief valve automatically cycles open closed whenever control line is by operator. When normally mechanism closed, also operator, causing inflate out housing. atmosphere opened, deflates partial vacuum created, thus refilling through valve.
