KNF IP65 UFEM 1.10 FT.18S2 Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to suit (more) most laboratory liquid metering and dosing needs. The UFEM 1.10 FT.18S2 version has a liquid transfer flow rate of 1 – 100 mL/min and discreet dosing volumes of 1 – 999 mL. It is constructed with the following chemically-resistant fluoropolymer flow path materials: PTFE head, PTFE covered diaphragm, and FFKM valves. The easy-to-read display combined with a touch control knob makes programming and access of all functions very intuitive. All SIMDOS pumps are simple and intuitive to operate, compact, and quiet, making them a welcome addition to any business or academic lab. They are effective against pressures of up to 85 psig and transfer viscous media up to 500 centistokes (reduced flow rate above 150 cSt). The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. With a durable and IP65 splash-proof design, these pumps are maintenance free, and provide trouble-free ±2% accuracy and ±1% repeatability performance. SIMDOS 10 pumps are self-priming up to 9.8 feet of water, and can run dry indefinitely without damage. Also, unlike peristaltic pumps, there are no troublesome tubing to break or fatigue.
