Rocker series pumps are driven by the diaphragm, without the need of lubricant, regular oil changes, and maintenance; with no oil pollution. Rocker series pumps are equipped with Prote™ overflow protection which can prevent a large amount of liquid from being sucked into the pump. Rocker series pumps are equipped with filter cartridge in air inlet to filter particle and moisture to prolong the life of pump. Rocker series pumps are equipped with vacuum regulator to adjust the vacuum. Every motor of Rocker series pumps has a built-in thermal protection device to shut off the pump automatically when overheated and then resume working when the temperature cools down.
The PTFE-coated diaphragm and chamber can offer good resistance to a wide range of corrosive gases except for strong acid and alkali.
