Granch Enterprise engineering milestones and industrial filtration portfolio

Established in Taiwan, Granch Enterprise Co., Ltd. traces its operational origins to 1971 when founder Lai Dengxiong formed Mingshan Enterprise, pioneering metal fabrication and building the first hydraulic folding unit in Taichung.

In 2002, the enterprise restructured under current leadership to inaugurate dedicated fluid purification engineering operations.

A defining technical breakthrough occurred in 2004 with the introduction of PRF70K high pressure filters for coolant through spindle tooling.

Today the Granch portfolio encompasses operating pressures up to 1000 bar, filtration fineness from 0.03 to 1000 um, and flow rates to 1000 L/min, providing complete protection for CNC machine hydraulics and cutting tool assemblies.

Engineering specifications of PRF70K high pressure through-spindle filters

Granch PRF70K high pressure filters are engineered specifically for demanding coolant-through-spindle fluid circuits on high-speed CNC milling and boring machines.

The robust metallic housing withstands continuous hydraulic flow surges, damping pressure oscillations and safeguarding rotary joints and microscopic internal tool coolant holes from abrasive wear.

The internal PRF70K filter element tolerates differential pressures up to 7.0 bar without media rupture.

The unit features an integrated visual differential indicator displaying a red warning at 3.0 bar alongside an internal safety bypass mechanism calibrated to 4.0 bar, preventing fluid starvation and tool thermal damage during peak particulate loading.

PRD70K series duplex switchable high pressure filter assemblies

For round-the-clock continuous production lines, Granch provides the PRD70K duplex filtration series. The assembly integrates two parallel filter chambers interconnected through a heavy-duty three-way diverter valve fitted with durable seals.

This arrangement directs the fluid stream through the active bowl while keeping the secondary unit in standby reserve.

When allowable differential pressure limits are reached, the machine operator rotates the selector handle without shutting down high pressure coolant pumps or pausing cutting execution.

Element changeout within the isolated chamber proceeds quickly and safely, eliminating downtime and preserving surface finish consistency on machined workpieces.

Automated GMP backwash systems and TCM3P coolant delivery equipment

Automated Granch GMP filtration stations and TCM3P pump packages continuously purge fine solid particulates from metalworking cutting fluids.

The systems incorporate patented reverse-pulsing tubular core technology protected by Taiwan patents M473271, M340096, M470694, and China patent ZL 2013 2 0746147.6.

When differential pressure triggers, automated controls activate a momentary reverse fluid burst, sloughing off filter cake and dense particulate sludge into an evacuation hopper.

TCM3P systems feature a space-saving skid design aligned with European CE safety standards, utilizing integrated GSV and GLSV shuttle valves for smooth fluid pressure control.

GFC mobile fluid conditioning carts and EOC electrostatic purifiers

To preserve operational lubrication properties across industrial power units and hydraulic systems, Granch manufactures GFC mobile filtration carts and EOC electrostatic purifiers.

Portable GFC units incorporate multi-stage high-efficiency filter elements for rapid offline reservoir conditioning, fluid transfer, and routine system maintenance.

The EOC electrostatic systems deploy high-voltage electrostatic fields to capture submicron fluid degradation compounds, dissolved resins, and varnish residues.

Submicron fluid conditioning eliminates spool sticking inside proportional and servo valves, reducing friction wear across hydraulic components and significantly extending lubricant drain intervals.

GDC cyclone separators, GPF flat-bed filters, and GMC magnetic units

Grinding and high-speed milling lines benefit from Granch GDC series hydrocyclone separators.

Centrifugal cyclone fluid dynamics isolate dense metal chips and abrasive grinding fines without consumable paper rolls, lessening pump wear and prolonging the working life of downstream high-pressure fine filtration elements.

For separating non-magnetic debris, GPF flat-bed gravity filters and GDF drum units feature automated indexing of non-woven filter paper rolls.

The product range is rounded out by GMC magnetic separators for capturing ferrous sludge and GFW-620 pneumatic oil skimmers that reclaim up to ninety percent of floating tramp oil.
