Introducing Bungartz, the centrifugal pump OEM behind Chemac, Inc.’s high-quality centrifugal pumps. Bungartz offers a full range of specialty centrifugal pumps for a wide variety of industries. The product line includes pumps that can run dry and perform reliably in environments where other pumps cannot keep up. Robust designs and quality craftsmanship are the foundation of the Bungartz family legacy. This commitment to quality is why customers continue to rely on the excellent reputation of Bungartz pumps. Here is a brief overview of Bungartz.
The History of Bungartz – 75+ Years of Innovation in Special Centrifugal Pumps Paul Bungartz GmbH & Co. KG, based in Düsseldorf, Germany, traces its roots to the 1930s when Paul Bungartz developed groundbreaking ideas for frictionless centrifugal shaft sealings. The company was formally founded in 1947 and has remained a family business focused on solving the most challenging pumping problems. Over 75 years, Bungartz has specialized in centrifugal pumps with hydrodynamic shaft seals that enable dry-running capability and reliable handling of difficult media.
From early patents to modern magnetic-drive and self-regulating designs, Bungartz pumps have earned a reputation for robustness where standard pumps fail. Today, the company supplies solutions worldwide for chemical, petrochemical, power generation, and slurry-handling applications, emphasizing “Made in Germany” quality, durability, and low maintenance.
How Bungartz Hydrodynamic Shaft Seals Enable Dry-Running Centrifugal Pumps Bungartz’s signature technology is the hydrodynamic (frictionless) shaft seal. Back vanes on the impeller and a seal expeller create a dynamic pressure barrier that prevents liquid from reaching the shaft seal during operation. When the pump stops or runs dry, the seal remains protected, eliminating the need for constant liquid supply or complex auxiliary systems.
This design allows safe dry-running, handling of boiling or gas-containing liquids, and low NPSH requirements. Combined with options like mechanical seals, packing, or magnetic drives, it delivers unmatched reliability for critical processes.
The Self-Regulating V-AN Series – Bungartz’s Solution for Varying Flows and Low NPSH The V-AN vertical centrifugal pump series automatically adjusts to fluctuating inlet conditions without additional controls or level sensors. With an NPSH value approaching zero, these pumps excel at handling boiling liquids, condensates, and media near vapor pressure without cavitation.
Ideal for tanker unloading, residual emptying, condensate drainage, and vacuum applications, the V-AN reduces installation costs and improves system safety in ATEX zones.
Bungartz MOS/UMOS Horizontal Pumps for Slurries and Corrosive Media The MOS and UMOS horizontal pumps use hydrodynamic sealing plus a gland packing or mechanical seal for versatile performance with abrasive, corrosive, or gas-containing slurries. They handle media like phosphoric acid, iron oxide slurries, gypsum suspensions, and titanium dioxide effectively.
These robust pumps serve chemical, petrochemical, and fertilizer industries, offering high availability and the ability to run dry safely during interruptions.
Magnetic Drive Pumps from Bungartz – Hermetic Safety for Hazardous Liquids Bungartz MPCH and similar magnetic-drive models provide hermetic sealing for toxic, explosive, or valuable liquids. The magnetic coupling transmits torque without contact, eliminating leaks while maintaining the benefits of hydrodynamic sealing and dry-run capability.
Suitable for high-safety applications in chemical processing and pharmaceuticals, these pumps combine efficiency with maximum environmental and operator protection across ATEX zones.
Bungartz Vertical and Submersible Pumps for Challenging Installations Bungartz vertical pumps (including semi-submersible designs) address low and varying NPSHa, limited space, and difficult suction conditions. Models like MPATAN offer dry-running submerged operation with magnetic drives, perfect for sump, tank, or pit applications with boiling or solids-laden liquids.
They minimize footprint, reduce piping needs, and deliver reliable performance where horizontal pumps struggle.
Applications of Bungartz Pumps in Chemical and Fertilizer Industries Bungartz pumps master aggressive duties in chemical plants, including molten urea, ammonium nitrate, sulfuric and phosphoric acids, and fertilizer slurries. Their ability to handle crystallizing, polymerizing, and abrasive media with minimal wear makes them indispensable for continuous production.
Self-regulating and dry-running features reduce downtime, while robust materials (stainless steels, special alloys, rubber linings) ensure corrosion resistance.
Power Generation and Condensate Handling with Bungartz Technology In power plants, Bungartz V-AN and related pumps efficiently drain condensates from steam lines and handle low-NPSH duties in feedwater systems. Their cavitation-free operation near boiling points and gas-handling capability improve efficiency and reliability in thermal power stations.
Innovations and Recent Developments at Bungartz At ACHEMA 2022 and beyond, Bungartz repositioned proven technologies like the MOR/UMOR slurry pumps and introduced enhancements for even higher availability. Focus areas include magnetic drives for dry-running, ATEX compliance, and solutions for extreme viscosities or shear-sensitive media.
Ongoing R&D emphasizes sustainability through energy efficiency and reduced maintenance in green chemistry and recycling processes.
Maintenance Advantages and Longevity of Bungartz Centrifugal Pumps Bungartz pumps minimize lifecycle costs with few wear parts, no mechanical seal flush systems in many configurations, and proven dry-run tolerance. Hydrodynamic seals and robust construction lead to high MTBF (mean time between failures) even with solids or boiling media. Routine maintenance focuses on simple inspections rather than frequent seal replacements.
Operators benefit from lower spare parts inventory and reduced downtime, making Bungartz the choice for mission-critical, difficult pumping tasks.
