Eriez HydroFlow has introduced the Deep Bed Gravity Filter. This innovative rolled media gravity bed filter provides significant operational advantages over typical gravity filters.
The advanced design of Deep Bed Gravity Filters offers long lead in and flow out of disposable media to eliminate dirty coolant by-pass around media. State-of-the-art features include wide sealing edges with heavy duty chain to secure side seals, deep bed to provide additional head to force liquid through media and heavy hot-rolled steel bar flights with flat edge to maintain media seal and ensure proper media tracking and advance.
"The key to success of the Deep Bed is the effective side seal and travel of the media and liquid depth to assist liquid permeation through the media, trapping the fine solid debris," said Tom Cassese, Director-Sales, Eriez HydroFlow.
Heavy-duty construction throughout these units prevents bed flexing, welds cracking or structural failures. For easy maintenance, flushing and cleaning, the gasket and bolted clean out port are positioned at the side of the clean tank.
Deep Bed Gravity Filters are engineered for straightforward, trouble-free operation. Electrical controls, with relays, push buttons and press-to-test pilot lights included, allow simple start-up of pumps and conveyor and provide a constant visual of coolant tank levels, pump pressures and coolant temperature. Heavy-duty chain and flight deep bed mechanical conveyors ensure maximum conveyor up-time for the continuous removal of swarf and solids contaminant.
The experts at Eriez HydroFlow work with customers to design the ideal system to meet their unique needs. Pumps are selected for respective flow and pressure from best available pumps. A variety of optional equipment is also offered to complement Deep Bed Gravity Filters, including a Magnetic Coolant Cleaner, Cartridge Filters, Recirculation Pumps and Drop-in Style Coil Chillers.
Deep Bed Gravity Filters are typically utilized for CNC grinding applications and achieve an average clarity level of 20-30µm with flows up to 90 gpm.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- swarf
swarf
Metal fines and grinding wheel particles generated during grinding.
