Blackmer E Series Magnetic Drive Gear Pump Features
|
|
|
| Between-the-Bearing Support System | One Fluid Chamber Design | High-Torque and Compact Magnetic Coupling |
| Eliminates the damaging effects of cantilevered loads that are present in competitor internal gear pumps, maximizing rotor, idler and bushing life. | Greatly improves fluid circulation through the magnetic coupling, resulting in lower operating temperatures, longer magnet life, and more effective cleaning and flushing processes. | High-strength magnetic couplings are standard to allow for more operational flexibility, with inner magnets mounted directly to the rotor for an extremely compact design. |
|
|
|
| Simple Design | Competitor Pump Interchangeability | Affordable Upfront Solution |
| The need for only seven primary components improves reliability and reduces system complexity while easing maintenance and repair. | Interchangeable with up to 95% of the packed, mechanically sealed and seal-less magnetic drive gear pumps in use today, with no need for piping, driver, baseplate or coupling modifications. | Due to the simple, seven primary-component part design, E Series Magnetic Drive Gear Pumps have a much lower investment cost than competitors’ magnetic drive gear pumps. |
