Features:
• All of the surface for contacting the media and working are ceramic.
• Plungers are connected with metal handles mechanically, and the viscose glue is filled between them to prevent the screw from getting loose.
• The superior comparing with existent ceramic plunger are anti-pull-off, connecting reliable, strong strength
• 10 times longer working life than metal plunger and also it gives a longer service life to the sealed packing material.
