EnviroGear

  • EnviroGear®, part of Dover Corporation’s Pump Solution Group (PSG®), is proud to offer this innovative, durable and environmentally friendly positive displacement gear pump. EnviroGear Internal Gear Pumps save you money by providing a low initial cost, high performance, and low maintenance costs. Our revolutionary seal-less design with patented between-the-bearing support system effectively eliminates leaks and mechanical wear, helping to increase personnel and environmental 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.
     
    ♦ Patented between-the-bearing support system technology
    ♦ Increased environmental and fluid handling safety
    ♦ High reliability and durability
    ♦ Single-fluid-chamber seal-less design eliminates leaks
    ♦ 50% reduction in maintenance costs
    ♦ Interchangeable with mechanically sealed and packed gear pumps
    ♦ Lowest overall cost of ownership
     

     
    Between-the-Bearing Support System For Increased Durability
     
    Other Pumps Technologies
    Traditional internal gear pumps support the rotor and idler gears using a performance-robbing, one-sided  support found in cantile-vered-load design.
     
    The EnviroGear Design
    The patented EnviroGear Design supports the roter and idler gears at three crucial locations.
     
     
    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. Materials are 4140 carbon steel or 17-4 PH stainless steel.
     
    Larger, long radial bushings support the entire length of the rotating element, which spreads out the hydraulic forces and allows the bushings to last longer.
     
    One-Fluid-Chamber For Enhanced Reliability, Fluid Safety
     
    Other Pumps Technologies
    Traditional magnetically-coupled positive displacement pumps are disigned with two fluid chambers separated by an adapter plate, resulting in product entrapment and poor reliability when moving high viscosity fluids.
     
    The EnviroGear Design
    EnviroGear uses magnets mounted directly to the rotor, eliminating the adapter plate, allowing for a single fluid chamber. This single-fluid-chamber design results in a much shorter, simpler flow path and allows the pump to easily handle fluids with high viscosities up to 50,000 cps while increasing bearing life and clean-ability.

     
    Interchangability Allows Upgrading Existing
    Gear Pumps With Minimal Installation Costs
     
    EnviroGear pumps have been designed to be interchangeable with up to 95% of the internal gear pumps that 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.
