Magnetic Liquid Traps Specifications
Powerful Rare Earth Separation
All Bunting® Cartridge-Style Liquid Traps are equipped with our Neodymium High-Intensity – NHI – Magnetic Cartridges, which lead the industry in their ability to attract and hold ferrous and weakly magnetic particles. These traps utilize a double-row of NHI cartridges oriented in the direction of product flow. This design offers three distinct performance advantages.
- Cartridges cover the entire flow yet are more closely spaced to create closer product contact with the magnetic field.
- With two rows of cartridges, the product flow is exposed to a backup row to collect tramp that might evade the first row.
- As the liquid product weaves through the cartridge grid, the inertia of ferrous tramp tends to keep it flowing on a straight course. With two closely spaced cartridge rows, there is no direct path by which ferrous particles can avoid contacting a cartridge surface, where the magnetic fields are strongest.
Mounting Location and Position
Thoughtful location and positioning of liquid traps can prevent maintenance problems and enhance overall performance. Their versatility and simple design help make it easy to locate traps in areas that are readily accessible for maintenance and cleaning. To protect against the greatest number of contaminant sources, install liquid traps in lines just before the next contaminant-sensitive operation, such as mixing, packaging, inspection, etc. To prevent damage to traps from overpressure, they should be installed on the suction side of pumps or as far away as practical on the discharge side.
In most cases, traps can be installed at any angle without affecting magnetic separation. For convenience, liquid traps should always be mounted vertically when used in a CIP, clean-in-place, system, so that the housing will drain itself of all liquids. Mount other units horizontally with the magnetic lid at the top at 90 degrees for most convenient cleaning or with the lid on the side at 0 or 180 degrees to facilitate purging or frequent manual cleaning of the housing interior.
How to Select Bunting® Magnetic Liquid Traps
Cartridge-Style Liquid Traps are the right choice for use with non-fibrous fluids that do not clog or contain solids larger than 0.5’‘ in diameter. For liquids that are fibrous or contain large solids, Plate-Style Liquid Traps should be used. Once you have chosen the style and model you need based on the products you handle, you need to address sizing and select options compatible with your application.
Match Your Line Size and Flow Rate Bunting® Magnetic Liquid Traps are engineered and sized to provide ample magnetic protection at typical pipe flow rates. Using the table below, find the liquid traps that match both the line size of your new or existing pipe or tubing and your flow rate requirements
Choose Magnets Matched to Your Operating Temperatures The standard magnet for Cartridge-Style MLT’s is the Neodymium High-Intensity, NHI, load. This magnet is intended for use in temperatures up to 180 degree° F. For high-temperature processing or where clean-in-place, CIP, systems might expose traps to elevated temperatures, specify our optional NHIT heat-resistant load. This Neodymium High-Intensity load is specially designed to operate in temperatures up to 300°F.
Plate-Style Liquid Traps come with N35UH magnets, which can handle temperature environments as high as 300° F.
Gasket Options All BMC Liquid Traps use sanitary gasketing which is certifiable to Dairy 3-A and FDA standards. Buna-N, nitrile, is supplied as the standard gasket material with EPDM and Viton® available as off-the-shelf alternatives. A replacement gasket is supplied with each trap. Keep extras on hand to prevent unnecessary downtime. Use the chart below to select the best gasket material for your application.
Fitting Options
All MLTs are supplied with two clamp fittings as standard equipment. But other fittings can be substituted to match your requirements. Choose from clamp, threaded bevel seat, and weld and pipe fittings in sizes 3/4’‘ thru 4’‘.
