The Best Bearing Seal For Ahlstrom APT 4 Pump: Isomag Bearing Isolators

September 5, 2018

The Ahlstrom APT-4 pump is an extremely popular pump found in paper mills across the United States. This horizontal single stage pump is most commonly used in low pressure, high flow rate transfers involving low viscosity fluids such as water. These pumps have proven to be robust and reliable in paper mills.

 

What are the features of Isomag bearing isolators and why are they so beneficial to your Ahlstrom APT 4?  

 

The benefits of an Isomag bearing isolator are:

  • Magnetic Closing Force – “Magnetic energy is used to create a closing force keeping the seal faces in positive contact.”

  • Seals in all positions: horizontal, vertical, angled, rock and roll

  • Seals in all types of bearing lubrication: splash, flooded, forced, oil mist

  • Seals during stand-by

  • Reduces stray mist from oil mist systems

  • Enables use of closed-loop oil mist systems

  • Easily installed by hand

  • Removable without damage to the isolator or equipment

  • Face seal that rotates with the shaft

Your Ahlstrom APT 4 will benefit from Isomag bearing isolators by providing a positive seal that prevents leakage, protects against the ingress of internal contamination, and provides years of reliable service. As the pioneers in the magnetic bearing isolator market, Isomag continues to bring innovation and technology in an effort to extend rotating equipment life.
