We are a manufacturer of filter press machines. These are used to transfer the sludge under pressure to the filter press to form a filter cake with a low acid content. By using these pumps, customers can save purified/sterilized water that cannot be saved with centrifugal pumps due to high pressure (see image on last page). Our customers who use our pump will make the cake even better. The fluid head is designed to handle a variety of chemicals/sludges.
