Take your pump performance to the next level with Blackmer seal-less E Series Gear Pumps. Innovative, durable and environmentally friendly, E Series Gear Pumps have been engineered to be a cut above the competition thanks to a revolutionary design with a patented between-the-bearing support system. This one-of-a-kind design eliminates leaks and reduces mechanical wear, helping increase the safety of site personnel and the environment. Material of construction options of ductile iron, carbon steel and stainless steel allow for a wide range of chemical compatibility. In addition, no other magnetically coupled pump offers a lower upfront cost, lower total cost of ownership or more reliability than the E Series Gear Pump.

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