The New Neumo Ehrenberg Group Trademark for our
ASME BPE Compliant Biopharmaceutical Fittings

MaxPure/BioPharm

Where cleanability of fittings is the issue, every step in the production process must be carefully controlled. Our production methods ensure insure that no mechanical damage or flaws occur during manufacturing. The cleaning procedures incorporate multi-process degreasing and washing steps provided to eliminate any residues of hydrocarbons and stains, using pure 18 MO deionized water. Our procedures and process capabilities result in the formation of a stabilized passive layer and increased corrosion resistance.

Our products proudly offer:

  • Maximum Cleanability
    Cleanability defines how easily contaminants can be removed from a surface. Our process guarantees the correct finish requirements, chemical composition and passivity state, with no major physical and / or metallurgical flaws.
  • Full Traceability
    We provide full traceability for each of our products by supplying all necessary production process data. Starting from certifications and incoming inspection of raw materials, through in-process quality control, final inspection, marking and packaging. The process is also completely documented with a unique job number for each BPE process component.
  • Every Fitting is Quality Inspected
    All around quality and meticulous inspection insures that every fitting will be of the highest quality and in total compliance with all ASME-BPE standards.

  • Cleaning:
    A seven step cleaning cycle is conducted to ensure that components are free of contaminants such as stains, oil, loose particles etc. In the final stage, the fittings are double-rinsed using hot DI water.
  • Inspection Procedures:
    All fittings produced by EGMO production are 100% visually inspected for any surface finish imperfections, as mentioned in Table SF-3 in the ASME BPE specification. All dimensional characteristics are inspected 100% for tolerances listed in Table DT-5 in the ASME BPE specification.
  • Marking:
    Each BPE fitting is marked with the following:
    • Heat number
    • Job number
    • Material grade
    • Standard
    • Surface finish (SFF), as specified in ASME BPE, Part DT.
    • Brand Name
  • Packaging:
    Each fitting is capped, bagged and labeled in full compliance with the ASME BPE standard.
  • Documentation:
    Full Material Test Reports are supplied with the finished products and via an interactive internet website, using a special private code.
