Many of KNF's larger pumps are offered with KNF's patented dynamic balancing system and an IP-44 TEFC AC motor. These pumps reach 1.5 Torr end vacuum in only 2 stages. Models are also available in full-PTFE wetted materials.

KNF's N816 and N836 pump series satisfy the requirements of steam sterilization and vacuum drying such as autoclaves. The pump heads are made of PPS, and condensate-repellant surfaces optimized liquid flow paths and fast drying. Shown at left is model N816.3.

NOTES: Standard continuous performance ratings listed on this KNF website and on KNF datasheets are based on technical data and test results of nominal units at sea level, measured with an ambient temperature of 70°F (21°C), and nominal electrical supply as listed above, and are for reference only.Multiple-head models, different performance models, cost-effective OEM modifications, and a variety of motor options and different materials of construction are also available. Certified drawings are available upon request. Specifications subject to change without notice. You should always check corrosion resistance charts for compatibility with the medium you intend to pump.
