Manually Cleaned Liquid/Solid Separating Centrifuge

Since 1992 US Centrifuge Systems has established itself as an innovative leader in centrifugal liquid / solid filtration technology. The US Centrifuge Systems Model M512 manually cleaned centrifuge is designed for a wide variety of tough processes and demanding liquid / solid separation / filtration applications where the specific gravity of the suspended solids are greater than that of the liquid. The long proven design and highly efficient operation separates small micron solids from a liquid medium for the recovery of valuable solids or recycling of industrial fluids.

The Model M512 manual clean centrifuge features a rugged heavy-duty frame design with a hinged enclosure cover and heavy duty lid clamps. The standard centrifuge-bowl is a hard-anodized precision-machined aluminum assembly that includes a stainless steel feed-cone and impeller mechanism for maximum separating efficiency. The removable standard bowl-liner is made from a durable 100-mil ABS-plastic and includes a bowl-liner lifting tool for easy removal of the separated sludge cake. Replacement plastic liners are affordably priced making spares an economical solution for faster clean outs and less down time. Spare bowl-lid SHCS and hex-key tool included.

Model M512 Machine Specifications

The Model M512 centrifuge is designed and built for safe, quiet, operation and years of reliable use in the most demanding applications yet requires relatively no day-to-day maintenance other than proper routine clean-out. The machines are American made with all engineering, manufacturing, service, and sales activities located under one roof in Indianapolis, IN for the convenience of our customers.

How the Manual Clean Unit Works

Process Cycle The dirty liquid continuously feeds through the 1′ NPT inlet / feed-tube and into the spinning bowl. The incoming liquid travels under the feed cone and into the bowl chamber where four impeller blades accelerate and maintain the liquid @ full rotational speed. The liquid then travels vertically up-ward through the bowl. Particles heavier than the liquid separate and move to the perimeter of the centrifuge-bowl depositing on the inside wall of the bowl-liner forming a dense solids cake that becomes relatively moisture free under accelerated gravitational force. The clarified liquid exits through the center hole in the bowl-lid and into the bowl-enclosure where it collects and drains out through the 3′ outlet fitting.

Clean Cycle After an elapsed time period of process time the bowl-liner reaches it solids holding capacity and the machine is turned off coasting to a stop. The hinged enclosure cover is unlatched and opened. The bowl-lid is removed from the bowl-bottom after unscrewing the four SHCS using the provided hex-key tool. Using the provided bowl-liner lifting tool, the liner is removed from the bowl- bottom. The solids are then scraped from the bowl-liner, which is then cleaned out and put back into the unit to resume operation.

The M512 manual clean centrifuge offers many advantages not found on competitive manual clean units:

• Rugged frame and integrated centrifuge-bowl enclosure designed and manufactured for maximum durability and longer working life.
• Hinged centrifuge-bowl enclosure lid secured by heavy duty clamps during operation and make opening the lid to access the centrifuge-bowl for cleaning quick and easy.
• Standard hard-anodized aluminum centrifuge-bowl surface finish for added durability and corrosion resistant
• Centrifuge bowls include a stainless steel feed cone and impeller assembly for improved separation efficiency.
• Easy to remove bowl-liners and included liner lifting tool make centrifuge-bowl clean outs quick and simple. All tools and a set of spare bowl lid screws are included with storage locations on the front of the machine.
• The spindle and centrifuge-bowl seat feature a tapered fit for smooth concentric operation. The spindle bearing-housing and centrifuge-bowl assembly can be easily and quickly removed from the machine frame as one unit for convenient and simplified maintenance when bearing replacement is necessary.
• A variety of standard options and system accessories allow a customer to tailor an M512 for their specific application and / or facility requirements

Complete Custom Systems:

Use as a portable unit to serve multiple fluid reservoirs or permanently locate the machine to serve a single dedicated fluid reservoir. The M512 can also be supplied as part of a complete pre-engineered system customized to suit a specific application and / or customer facility requirements. A variety of tanks, pumps, valves, piping, machine platforms, and system controls are available.

The standard machine features a carbon steel powder-coated frame with an aluminum bowl-shell, and precision carbon steel bearing housing assembly. The machine is also available with a complete stainless steel rotating assembly and or all wetted surfaces constructed from 316L stainless steel.

Standard XP unit configuration is available for screen print solvent recovery applications.

The M512 manual clean centrifuge is ideal for fluid clarification / liquid recycling applications where other filtration methods fail. And, the M512 can handle tough, abrasive, sticky, and hard packing materials with minimal wear and tear on the centrifuge. A sample of successful applications include: Solvent Recovery, Carbide cutting oils, Glass and ceramic grinding coolants, Machining coolants, Parts washing fluids, Cold heading machine lubrication, Die lube, ECM EDM fluids, Ophthalmic lense grinding coolants, Phosphate solutions, Quench oils, Screw machine oil, Thread and rolling oils, UF pre-treatment, Used oil clarification, Vibratory finishing, Industrial wastewater, Water wash Paint booths, and many more.

General application benefits include:

• Operation requires minimal time and attention
• Cleaner working fluids equal improved product quality
• Extended process liquid, media, and tool life
• Reduced production equipment downtime for maintenance and clean outs
• Minimized waste volumes with relatively dry drip free sludge and no consumable filter elements
• Environmental compliance
