For high throughputs,
consider this dry vacuum pump
The iXL 500 (photo) is the first member of the new iXL line of dry vacuum pumps. The iXL 500 is designed primarily for load-lock applications in solar-cell and flat-panel-display manufacturing where high gas throughputs and fast pump-down times are crucial. Compared to its predecessor, the iXL 500 offers up to 60% improvement in cost of ownership, says the manufacturer. The unit has a pumping speed of 1,600 m3/h while consuming only 7 kW of power. Its low-inertia booster shortens load-lock evacuation times with faster, more efficient pumping at higher inlet pressures. — Edwards, Crawley, U.K.
This standardized canned-motor pump
has built-in protection
The newly developed HCN/HCNF range of canned motor pumps was designed for the most demanding areas of application. The HCN range is designed for aggressive, inflammable, toxic and highly volatile liquids, solvents or other substances. The HCNF range is used for liquid gases, such as ammonia, Freon, propane and carbon dioxide. The most recent development is a single-stage standardized chemical canned motor pump (photo, p. 32I-4) in accordance with EN 22858/ISO 2858. The area of application for liquids covers a temperature range from –120 to 120°C. The pump performance lies between 6 and 41 kW, with a maximum flowrate of 230 m3/h and a maximum head of 140 m. One special design feature is an integrated monitoring system for the rotation direction, which is firmly molded in the terminal box. A thermistor secured in the winding guarantees efficient protection of the motor. — Hermetic-Pumpen GmbH, Grundelfingen, Germany
A better way to make pellets
of PS and POM
The WRG range of water-ring pelletizers (photo) for making pellets of polystyrene (PS) and polyoxymethylene (POM) has the advantage that the cooling and conveying medium (water) does not come into direct contact with the die plate. The rotating knives cut the extruded strands of melts into pellets. Centrifugal action of the knives sends the still-hot pellets into the rotating water ring, which cools them and conveys them out of the pelletizer hoods. Favorable operating costs result from: the low energy requirement for the die plate and the rotor drive; the negligible wear on the knives and the die plate; and the simple and rapid startup process. A WRG 320 has been delivering 5,000 kg/h PS pellets for two years, and a 9,000 kg/h unit has recently been delivered. — Coperion GmbH, Stuttgart, Germany
track rotating equipment
The DN8033 thrust and rod drop transmitter (photo) is designed to measure shaft axial or rod position of a range of rotating equipment. The 4–20-mA loop-powered module provides easy integration with either the local machine PLC or a plant-wide DCS since it is powered through the measurement loop. The unit operates in conjunction with the company’s Senturian range of 8-mm-dia. proximity probes, offering a maximum measurement range of ±1 mm. The DIN rail-mountable unit provides two miniature multi-turn potentiometers for the setting of the gain and zero point parameters. — Sensonics Ltd., Berkhamsted, U.K.
A control valve
with faster action
Emerson Process Management
The Fisher Control-Disk valve (photo) offers excellent throttling performance and is ideal for applications that involve fast processes and varying pressure drops. The valve’s wide control range is twice that of traditional butterfly valves for better adherence to set point, which allows control closer to the target set point, regardless of process disturbances. When paired with a Fisher spring-and-diaphragm actuator and Fieldvue digital valve controller, the assembly can capture and deliver data to AMS ValveLink software, which provides an accurate picture of the valve, actuator and digital-valve-controller performance. The valve body meets PN 10 through PN 40, CL 150, and CL 300 ratings. Face-to-face and raised-face dimensions meet EN 593, API 609 and MSS-SP68 standards. — Emerson Process Management, Baar, Switzerland
Charge more than reactors
with this powder-transfer system
Dietrich Engineering Consultants
Although especially designed for safe reactor charging, the PTS powder-transfer system (photo) has proven itself in many applications of a much wider spectrum than traditional reactor charging. The PTS-System is exempt from ATEX 95, and therefore does not need an ATEX certification or confirmation. The system does not create its own ignition source and therefore is intrinsically safe. By means of active powder transfer, by a combination of vacuum and pressure, the PTS is able to replace risky open manual handling. Powders can be transferred from almost any receptacle, such as sacks, big bags, drums or storage vessels, and be discharged into any type of receiver. The system can be mounted directly on a vessel or is available as a mobile unit. The PTS is fully CIP (cleanable in place) and guarantees hygiene and complete containment. — Dietrich Engineering Consultants S.A., Ecublens, Switzerland
A peristaltic pump
