Chemical resistance & effective
Applied with PTFE-coated diaphragm and pump head with FKM valves, Rocker 300C pumps are adequate to work in milder chemical gases and be cost-effective at the same time.

Oil-free & care-free
Rocker 300C pumps are driven by diaphragm that needs no lubricant, making them maintenance-free and oil-mist-free.

Minimized vibration & quiet
Superior weight distribution and assemblies minimize the vibration and noises and maximize stability.

Overheat protection
Rocker 300C pumps are equipped with overheat protection device that shuts down when overheated and resumes once cooled down, making the pumps safer and long-lasting.
