Filter Press Shutdown

Proper shutdown directly affects the filter press’s service life and subsequent working efficiency, so shutdown procedures must never be neglected. Maintenance is mandatory right after shutdown.
The equipment cannot be left unattended after filtration. Our company recommends the following steps after power-off to guarantee smooth restart next time.

First, drain all residual filtrate inside the machine. Remaining liquid will dry and harden into solids while standing, clogging key components, causing startup faults or filter cloth rupture. Flush leftover filtrate fully to avoid solidification or chemical deterioration.

Keep filter cloth moist after use. High pressure and filtrate alter cloth structure; dry cloth shrinks severely, reducing solid retention performance and accelerating damage. Carry out cloth maintenance promptly upon shutdown.

In addition, prevent water ingress into the hydraulic station to avoid hydraulic oil deterioration. Inspect and maintain hydraulic seals after every shutdown.
