Maggie Magnetic Separator

The ZGF Magnetic Separator (“Maggie”), is an innovative and patented technology. The fully automatic, in-line, high intensity, self-cleaning, patented magnetic separator is the best available technology for separating magnetic contaminants from process fluids. Maggie can remove particles down to 1 micron without damaging critical process fluids such as machining coolants, cleaning / degreasing solutions or polymer quench fluids.

Zero Gravity Filter’s Maggie is an effective, efficient and environmentally responsible solution that can optimize life-cycle cost and minimize the environmental footprint of industrial operations where ferrous (magnetic) contaminants are present/introduced.

High-Intensity Magnetic Separator Optimizes Contaminant Capture

Media filters such as cartridge filters and roll media create a physical barrier which captures all particles larger than the micron opening. You don’t want to remove everything! For example, you don’t want to remove defoamer particles, surfactant micelles or emulsion droplets. You want to remove the contaminants, the ferrous fines and particles that deteriorate the process fluids, negatively impact quality and productivity, and drive up maintenance costs.

Take two minutes and watch the video below to better understand how the best-in-class Maggie Magnetic Separator technology works. After watching the video, we are sure you will be thinking of many processes and applications in your facility where ZGF magnetic separation technology could provide significant value.

Magnetic Separation Technology Design & Fabrication

Maggie’s stainless-steel body houses our proprietary magnetic cores. The magnetic cores are thin walled, seamless stainless tubes that seal magnetic shuttle assemblies. Each magnetic core contains several magnet/pole combinations that generate a magnetic field greater than 10,000 Gauss at the surface of the tube. The magnetic cores are assembled into different Maggie sizes/models to best accommodate the flow and loading characteristics of the application/process.

All of Maggie’s wetted components (other than elastomers) are stainless steel. Maggie is compatible with a wide range of liquids and operating conditions up to 200oF and 100 psi. Maggie is available with four valve seat materials (Viton, Buna, EPDM and Teflon) and four O-ring materials (Viton, Buna, EPDM and ETP). Valve Seat and O-ring material selection is based upon compatibility with the process fluid.

The five Maggie models are designed to handle flow rates from 1 gpm to 250 gpm. Multiple Maggie's can be assembled in a manifold arrangement to meet any flow requirement.

Magnetic Separation Technology Control Options

Three different types of Maggie controls provide an easy and convenient way to program Maggie to your exact specifications. All control system options feature automatic purge (i.e. self-cleaning cycle) based on time interval and manual override functionality. The Maggie Control options include:


  • Analog Timer – for use with MG100, MG300 & MG600. ZGF’s most basic control system. The analog timer has minute dial for setting the purge interval and second dial for setting the purge duration. The timer is also equipped with a push button for initiating a manual purge. The analog timer is mounted directly on the Maggie valve assembly. There is no control enclosure to mount.
  • Proprietary, Solid-State, Printed Circuit Board (PCB) control system – for use with all stand-alone, individual models, and when an individual Maggie is used in conjunction with Smart Drum or Smart Drum PLUS. The PCB controls are housed in a NEMA 4, painted steel enclosure with a membrane keypad and LCD display that allows the user to configure timers and displays operational status.
  • Logic Module (Siemens LOGO!) – for use with any single Maggie, multiple Maggie systems, when adding Maggie Watch, or when the operator requires greater range of control. The controls are housed in a NEMA 4, painted steel enclosure or a NEMA 4X stainless steel enclosure. A door mounted user-interface allows the user to configure timers and displays operational status. An LED stack light provides system status (i.e. power on, purge and fault / alarm). The LOGO! controls also provide some interface capability with other control systems.

Maggie Watch: Magnetic Separation Fault Monitoring System

The Maggie Watch allows for continuous monitoring and immediate notification should one or more Maggie’s experience a fault. The system provides capability for local and remote monitoring and alarm notification. Detection and early action will make the repairs much easier and prevent damage to Maggie components and downstream components.

Maggie Watch continuously monitors for all potential Maggie faults, including:

  • Low or loss of air pressure,
  • Magnetic Shuttle does not move,
  • Magnetic Shuttle Air Leak (Internal Air Leak Detection),
  • Tube Seal Leak (Internal Process Fluid Leak Detection),
  • Purge and/or discharge valve does not open or close.

Maggie is the Premier Magnetic Separation Technology for the Removal of Ferrous Contaminants and Particles

Maggie is the best technology for removing ferrous contaminants from process fluids. The Maggie Magnetic Separator also maintains the lowest 10-year lifecycle cost and is extremely environmentally friendly; Maggie’s environmentally responsible design is the “green standard” and is highly respected throughout the industry.

Maggie – Filter Mode

  • Dirty fluid enters in top
  • Magnetic shuttle assembly in lower position
  • Particles are trapped on the outside wall of tube
  • Clean fluid is discharged through the outlet port
  • Purge port closed, discharge port normally open

Maggie – Purge Mode

  • Dirty Fluid enters in top
  • The discharge port is closed, purge port is opened
  • Using compressed air, the magnets are shuttled to the upper position
  • The solids have nothing to cling to and are easily washed away through the purge port

The purge (automatic, self-cleaning) process is:

Quick: 4 to 6 seconds

Efficient: < 0.50% of the process volume

Effective: 100% clean with each purge

Simple: No mechanical scrapers or wipers. No media. Compressed moves the magnetic shuttles up and down
