EnviroGear® E Series Pump Your Seal-Less, Leak-Free Solution

Take your pump performance to the next level with EnviroGear® E Series Magnetically Coupled Seal-less Internal Gear Pumps. Innovative, durable and environmentally-friendly, E Series 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. In addition, no other mag drive internal gear pump offers a lower upfront cost, lower total cost of ownership or more reliability than the E Series.

Features

Between-the-Bearing Support System

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

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-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

Simple Design

The need for only seven primary components improves reliability and reduces system complexity while easing maintenance and repair.

Competitor Pump Interchangeability

Competitor Pump Interchangeability

Interchangeable with up to 95% of the packed, mechanically sealed and seal-less internal gear pumps in use today, with no need for piping, driver, baseplate or coupling modifications.

Affordable Upfront Solution

Affordable Upfront Solution

Due to the simple, seven primary-component part design, E Series pumps have a much lower investment cost than competitors’ mag drive pumps.
