The Ramparts air-operated diaphragm pump has unique features and solid characteristics that make it stand out as your best choice for handling thick and solids-laden sludges and slurries:
  • Heavy-duty construction. Ramparts air-driven diaphragm pumps are built with heavy-duty air cylinders and rugged, extra-thick casings for outstanding stability.

    The air cylinder is chrome-plated for extra-long life, and the pumps are cast from ductile iron -- some even available in stainless steel.

  • Stroke indicator rod. Ramparts pumps are built with a stroke indicator rod that allows 360° visual monitoring of pump operation.

  • Heavy-duty linings. Take your choice of linings, depending on your application needs: Hypalon®, neoprene, Nordel®, natural rubber, Nitrile®, and Vitron® are all available.

  • Superior solids-handling capacity. The Ramparts air-driven diaphragm pump can move large spherical solids without clogging -- an important feature for any plant where sludges and slurries are flowing.

  • Capacity for high solids contents. Sludges and slurries with high solids content can still move in a Ramparts air-driven diaphragm pump. The highly efficient air-driven design delivers high capacities for the long haul. Your sludge pumps and slurry pumps have to be reliable, and Ramparts pumps are the most reliable anywhere.

  • Outstanding cost efficiency. After years of trouble-free service, a Ramparts sludge or slurry pump may need to be rebuilt with new check valves or a new diaphragm. The cost of a complete rebuild is about one-fifth the price of the original pump -- meaning your Ramparts pump is an investment that will pay for itself over and over for years to come.

  • Simple, infinitely-adjustable controls. With the easy-to-use Ramparts controller, you can adjust stroke rates and pressures to fit your pumping needs exactly.

  • Packaged systems engineered at the factory. An engineered Ramparts pump system is built and packaged at the factory and delivered in a corrosion- and mildew-resistant fiberglass enclosure. A complete station comes with pumps, air compressor, controls, and internal piping ready to operate -- just add power and external piping.

  • Smooth operation. Ramparts sludge pumps can be tuned to remove sludges from a clarifier or settling basin at precisely the rate of accumulation. With a Ramparts sludge pump, your wastewater reclamation can be efficiently tuned to prevent solids re-suspension.
