KNF often partners with equipment manufacturers to produce modified pumps for their instruments or equipment. Because these custom-manufactured pumps have been modified to match specific performance requirements, they are not "standard" KNF products and, therefore, not listed on this website. Examples of custom-manufactured, project pump model numbers include: MPU, PE, PF, PJ, PJM, PL, PM, PME, PMF, PML, PMM, and PU.
To obtain a replacement pump for your instrument:
KNF does not stock modified pumps for OEM instruments. Please contact the instrument manufacturer for complete replacement pumps. Also, please beware of substitute imitations which may damage your instrument, void a warranty, or increase risks to personal safety.
