Frequently Asked Questions

What is the working principle of a filter press?

A filter press works by pumping slurry into chambers formed by filter plates. Pressure forces liquid through filter cloths, retaining solids as cake. Once filled, the press opens and cakes are discharged.

How often should filter cloths be replaced?

Filter cloth life depends on application, but typically lasts 3–12 months. Regular inspection and proper cleaning extend service life.

Can Longone provide turnkey solutions?

Yes, we offer complete turnkey projects including design, equipment supply, installation, and commissioning support.

Do you offer after-sales service?

Yes, we provide technical support, spare parts, maintenance training, and remote troubleshooting assistance globally.
