Internal Gear Pumps have seal-less design.

Press Release Summary:

Designed for critical fluids transfer, EnviroGear® Seal-less Internal Gear Pumps come in ductile-iron, carbon steel, and stainless steel. Seal-less design with between-the-bearing support system eliminates leaks and mechanical wear. Also, magnets mounted directly to rotor eliminate adapter plate and allow for single-fluid chamber. This provides short, simple flow path and allows pump to handle fluids with viscosities up to 50,000 cSt while increasing bearing life and cleanability.

PSG's Maag Industrial Pumps Introduces EnviroGear®Seal-less Internal Gear Pumps

Designed for the safe and efficient transfer of critical fluids

Oakbrook Terrace, IL, USA –PSG’s Maag Industrial Pumps, the global leader in positive displacement pumpsand systems,is pleased to announce the addition of EnviroGear® Seal-less Internal Gear Pumps to its product portfolio.

The EnviroGear Seal-less Internal Gear Pump line is now part of PSG’s newly created Maag Industrial Pumpsplatform. Maag Industrial Pumps will feature a new brand image and pump technologies targeting general industrial applications. The combination of PSG’s product portfolio of gear and screw pump technology along with Maag’s strong brand reputation of quality, innovation and customized solutions will strengthen EnviroGear’s global position. PSG will use its global manufacturing facilities, engineering capabilities, as well as its pump and systems expertise to deliver value-added solutions to EnviroGear customers.

The EnviroGear pump features a revolutionary seal-less design with patented between-the-bearing support system, which effectively eliminates leaks and mechanical wear, making it one of the safest and most reliable gear pumps in the industry. Its design also uses magnets mounted directly to the rotor, eliminating the adapter plate, which, in turn, allows 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 cSt while increasing bearing life and cleanability.

EnviroGear Seal-less Internal Gear pumps are available in ductile-iron, carbon-steel and stainless-steel construction with differential pressures from 1.4 to 13.8 bar (20 to 200 psi) for ductile-iron and carbon-steel models, and 1.4 to 10.3 bar (20 to 150 psi) for stainless-steel units. All pumps are available for temperatures from -40ºC (-40ºF) to 260°C (500°F).
