    • Explosion-proof peristaltic pump is driven by AC gear explosion-proof motor, split design, and the driver is separated from the frequency converter.
    • Explosion-proof peristaltic pump must be used in conjunction with the frequency converter. It has the functions such as start/stop, forward/reverse, speed regulation, and communication.
    • Planetary reduction mechanism design. Stepless variable speed, adjustment resolution 0.1Hz.
    • Explosion-proof peristaltic pump has IP55 high protection grade, suitable for complex industrial environment.
    • If the explosion-proof peristaltic pump needs to be placed in a dangerous industrial environment, an explosion-proof converter should be selected.

    Tips: Pipeline configuration and precautions of explosion-proof peristaltic pump.

    The reason why the explosion-proof peristaltic pump can transport all kinds of liquids and various foods with abrasive, corrosive, and oxygen-sensitive characteristics is mainly because the peristaltic pump has a superior pipeline configuration.

    1. The suction hose of explosion-proof peristaltic pump is 1 to 3 levels larger than the inlet diameter or equal.
    2. In order to facilitate maintenance and use, the suction tubing should be equipped with a shut-off valve and be as close as possible to the pump inlet, with the same diameter as the tubing diameter.
    3. To protect the explosion-proof peristaltic pump from being damaged, a filter is installed immediately downstream of the pump suction pipeline and the shut-off valve, usually a T-type filter.
    4. A safety valve is set between the outlet of explosion-proof peristaltic pump and the first valve.
    5. The outlet of explosion-proof peristaltic pump is equipped with a pressure gauge, which is located on the straight pipe section between the pump and the first valve at the outlet.
    6. On the outlet pipeline of explosion-proof peristaltic pump, set a drain valve between the first valve and the pump.
