Millennium Series

Heavy Duty Progressive Cavity Pumps

Millennium Series Icon The Millennium Heavy-Duty Progressive Cavity Pumps are designed for the most difficult positive displacement pumping applications like heavy and abrasive sludges, greases and slurries in sewage and reclamation processes as well as Return Activated Sludge (RAS), Thickened Waste Activated Sludge transfer (TWAS) and sludge dewatering and chopper transfer pumping in wastewater facilities. The Millennium series is well suited for the waste-oil and crude oil reclamation and transfer industry.

All Millennium Series parts such as Rotors and Stators or Wetted parts such as Connecting Rods and Seals dimensionally interchange as aftermarket replacements with other popular manufacturers pump models like the Moyno® 2000 Series and the Tarby® Century V Series, and the Continental® CG Series of Progressive Cavity Pumps potentially saving you and your facility thousands of dollars in replacement part costs yearly.

Over 500 wastewater, waste-transfer, and dewatering facilites in North America currently use Millennium parts in their daily service with little to no appreciable loss in performance vs. OEM competitors with a yearly savings averaging 35% over OEM prices for replacement pumps and parts.

The Millennium series starts with a heavy-duty cast iron bearing frame with large bearings to transmit heavy work loads easily and provide long service life. The pumps positive sealed universal joints are heavy-duty gear joints that keep the lubricant in and dirt and other foreign contaminants out during operation.

Pump rotors for the Millennium Series are milled from hardened tool steel or corrosion-resistant stainless steel and then coated with hard chrome plating for increased durability and abrasives resistance. Special wear coatings like titanium or other exotic coatings are available upon request.

Pump stators are injection molded rubber which is available in many specialized compounds depending upon your pumping application. We manufacture stators in buna nitrile for general applications and Viton® for additional chemical compatibility at high temperatures. Other rubber compounds such as natural rubber and EPDM are available upon request.

We stock all pumps and replacement parts at Liberty Process Equipment for immediate shipment to your location.
