VACUUBRAND MD 4 VARIO Select Diaphragm Pump Ultimate Vacuum 1 mbar (0.75 Torr) Maximum Pumping Spee (more)d 3.4 CFM at 60Hz Number of Heads/Stages 4/3 Features - VACUU-SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory - Extraordinary diaphragm life for minimum operational and servicing costs - Contamination-free pumping and evacuation - Excellent ultimate vacuum and TURBO-MODE for use as backing pump for turbo pumps This three-stage diaphragm pump is an excellent solution for continuous, oil-free pumping of non-corrosive gases to a vacuum level as deep as 1 mbar. All wetted parts are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of applications with non-corrosive gases. The MD 4 VARIO select continuously adapts its motor speed to hold the desired vacuum level. That means the pump is whisper-quiet and generates ultra-low vibrations and has high leak tightness. The highly flexible fabric reinforced double FKM diaphragm is ideal for extended operating life. The VARIO design includes the variable speed pump and the VACUU·SELECT vacuum controller with external gauge head. The demand-responsive motor speed control on VARIO models further extends the already long lifetimes of diaphragms and valves. These three-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases at demanding vacuum conditions. They are especially suitable for applications requiring high volume flow in physics and analytics. The low ultimate vacuum makes these an attractive alternative to rotary vane pumps. Typical uses are as backing (roughing) pumps for turbomolecular drag pumps, for degassing of viscous media, as well as for exhaust gas analytics. Additionally, the VARIO model provides vacuum control by precise adjustment of the diaphragm pump´s motor speed to process requirements. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. For equipment manufacturers customized versions are available. Depending on the application, the demand-responsive motor speed control of VARIO models further extends the long diaphragm life for which VACUUBRAND pumps are well-known. In addition, it provides an even higher pumping speed and enables precise vacuum control. INCLUDED: The VACUUBRAND MD 4 VARIO Select Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

KNF IP65 UFEM 1.10 KT.18S2 Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to sui (more)t most laboratory liquid metering and dosing needs. The UFEM 1.10 KT.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 flow path materials: PP 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.
