EQUIPMENT & SERVICES << LIQUID HANDLING PUMPS END NEED FOR REFILL CYCLES The Cheminert Model M6 and M50 liquid handling pumps are a new generation of positive-displacement pumps for precision handling of liquids and/or gases, producing a bidirectional pulseless flow with a range of over six orders of magnitude (10 µL/min to 10 mL/min for the M6 Pump; 50 µL/min to 50 mL/min for the M50 Pump). Suitable as replacements for syringe pumps, the pumps reportedly offer peak performance and eliminate the need for refill cycles and syringe changes. RS-232 and RS-485 communication protocols are incorporated into the microprocessor-driven controller. USB interface requires an adapter. Valco Instruments Co., Inc. (800) 367-8424 www.vici.com DIAPHRAGM SEALS PROTECT SENSORS PUMP OFFERS DURABILITY AND FLEXIBILITY The high-performance PowerFlow pump offers versatility and performance ruggedness. The pump features a cast iron body and A 2 tool steel pumping elements or, for corrosive applications, 17-4 pH stainless steel pumping elements. The pump also features the Power Seal, with standard 316 SS construction, Viton O-rings and hard silicon carbide faces, or optional tungsten carbide faces and O-rings of nitrile, EPDM or Kalrez. It can handle flows to 400 GPM and differential pressures to 1,500 psi, temperatures up to 350°F standard (with up to 500°F optional) and up to 40% by weight of solids. Moyno Inc. (877) 4UMOYNO www.moyno.com These threaded, off-line diaphragm seals isolate sensors from the process media, extending instrument life. They can be used with a variety of instrumentation as well as lend themselves well to complex seal assemblies. These seals have a large diaphragm, which increases accuracy and allows for low pressure readings. They have welded diaphragms, allowing the lower housing to be removed for easy cleaning without losing fill. There are a variety of process connections available, including ¼-in., ½-in., ¾-in., and 1-in. NPTF. The standard diaphragm and lower housing material is 316 SS with other materials available REOTEMP Instruments (800) 648-7737 www.reotemp.com TUBULAR MEMBRANES LOWER OPERATING COSTS Inducor and Inducor-G tubular modules for ultrafiltration of process streams and wastewater have high packing density and require less power than traditional tubular membranes, resulting in systems with a smaller footprint and reduced capital and operating costs. The modules use the same proven KMS PVDF ultrafiltration membrane that has been used with the FEG tubes and ultra-Cor modules. The membrane is compatible with most industrial wastewater streams and is especially well suited for the treatment of oily wastes and metal hydroxide wastes. Inducor modules are configured with ½-in. diameter tubules and Inducor-G modules have 1-in. diameter tubules.
