W h e r e I n n o v a t i o n F l o w s

Maag , part of Dover Corporation’s Pump Solutions Group (PSG®), is a leading global provider of innovative, high-quality industrial gear pumps for the safe and efficient transfer of liquids . Maag is proud to offer EnviroGear®, a durable and environmentally friendly positive displacement seal-less gear pump. EnviroGear pumps save you money by providing a low initial cost, high performance and low maintenance costs.

Our world-class distributor network ensures that you will have access to the pump you need when you need it. We are devoted to your business’s success, servicing your needs with world-class products, delivery and best-in-class expertise. EnviroGear combines all of this while offering some of the shortest gear pump lead times in the industry. Put us to the test today and contact your local distributor at www.maag.com

Our revolutionary seal-less design with patented between-the-bearing support system effectively eliminates leaks and mechanical wear, helping to increase personal and envi-ronmental safety. Leveraging unique patented design features, EnviroGear is not just a magnetically coupled, mechanically sealed or traditional internal gear pump. EnviroGear has completely reinvented internal gear pump technology with a true engineered solution specifically designed from the inside-out for environmentally conscious fluid handling, both for thin fluids, as well as hard-to-seal viscous fluids.

Interchangability Allows Upgrading Existing Gear Pumps With Minimal Installation CostsEnviroGear pumps have been designed to be inter-changeablewithupto95%oftheinternalgearpumpsthat are currently available in the market. That means no piping changes, no driver changes, no coupling changes, no flow-rate changes and no baseplate changes. The EnviroGear side-ported casing is also interchangeable with a number of lobe pumps.

E1-Series: EnviroGearSeal-Less Internal Gear Pump

OneFluidChamber Forenhanced Reliability,Fluid Safety

The EnviroGear DesignThe EnviroGear uses magnets mounted directly to the rotor, eliminating the adapter plate, allowing for a single-fluid cham-ber. This single fluid-chamber design results in a much shorter, simpler flow path and allows the pump to easily handle fluids with highviscositiesupto50,000cStwhileincreasingbearinglife and cleanability.

EnviroGear Eccentric Spindle(3 Support Locations)

Between-the-BearingSupport System For Increased Durability

The EnviroGear DesignThe patented EnviroGear design supports the rotor and idler gears at three crucial locations with an Eccentric Spindle that is supported in the head, the crescent location and the back of the containment canister, eliminating much of the effects of cantilevered load. Larger diameter, harder materials provide

more rigid support for less shaft deflection and bearing wear. Materialsare4140carbonsteelor17-4PHstainlesssteel.Large,longradial bushings support the entire length of the rotating element, which spreads out the hydraulic forces and allows the bushings to last longer.
