Application

The HydroPur filter system is a fleece filter for cleaning the cooling lubricant (KSS) in machining processes. It is used as an independent cleaning unit (e.g., when grinding) or as a supplement to chip transport systems (e.g., when milling).

Properties	Benefits
Higher hydrostatic pressure compared to flat bed filters	• Higher volume flow • Less fleece consumption • Better level of purity
Build-up of a homogeneous filter cake, especially when grinding	• Good filter quality • Short delivery time
Standardized construction	Favourable price-performance ratio
Modular design with configurable functional units	Optimal coverage of customer requirements
Plug-and-Play via universal, digital interface	Quick installation and start-up
Control with KNOLL SmartConnect	Simple operation and monitoring, also with a smartphone or tablet

Description

Filtration process

The dirty coolant goes from the machine tool into the filter trough
Due to the hydrostatic pressure, the liquid flows through the filter fleece, which holds back the dirt particles
The dirt particles form a filter cake that separates even the smallest particles
The clean liquid flows into the filter chamber and collects in the clean tank
Supply pumps supply the machine tool with cleaned coolant as required

Regeneration process

The growing filter cake increases the flow resistance
The liquid level in the filter trough increases
The belt drive switches on at a defined level
The carrier belt transports a piece of clean filter fleece onto the filter surface
The level of the liquid decreases again
A sludge container or a take-up unit takes up the dirty filter fleece
