New Diaphragm Pump Offers Minimum Format With Maximum Efficiency
New Pump Easily Handles Air Sensitive, Crystallising Fluids
Fluid Metering (USA) announces their new 'Low Volume Valveless Metering Pump' for precision dispensing of air sensitive, crystal forming fluids.
FMI’s miniature “H” Series Pump Heads are now available with an isolation gland to provide a fluid barrier between the pumped process fluid and atmosphere. These pumps are ideal for maintenance-free dispensing of saline based reagents, buffers & wash fluids, slurries, abrasive fluids, fluids with particulates, inks, pigments, anaerobic fluids, dialysate used for hemodialysis, and much more.
Isolation gland pumps have a pair of extra ports which are connected to a fluid source (either liquid or gas). The fluid flowing through the gland ports provides a barrier which isolates the pumped process fluid from the seal area and atmosphere. The isolation gland is easily connected to the “barrier” liquid or gas source via barbed fittings.
The dual model of the SP 100 EC miniature pump from Schwarzer Precision (Germany) offers pump technology at the highest level.
With the world’s smallest diaphragm pump SP 100 EC as dual model 100 EC-DU Schwarzer Precision offers first-class miniature pump technology in its most compact format.
The light-weight of 15 g with a size of only 13 x 22 x 32 mm finds it use especially were condensed design is very important. As all eccentric diaphragm pumps of the SP 100 series the SP 100 EC- DU distinguishes itself through lowest current consumption and is therefore especially suited for portable analysis devices.
Two of the latest technical innovations from Schwarzer Precision make the pump a top product: Maximum flow rates and flow- optimised delivery channels in the pump head are achieved with the TN technology („No Turbulence Technology”). The active balancing system IBE (Individually Balanced Eccentric) provides extreme quietness of running as it is otherwise found only with much larger pumps.
Utilising the opposing plunger principle the dual pump allows delivery of two different media in parallel. It is equipped with two identical pump heads each of which is operated by the same shaft end of the motor. This means optimal utilisation of the design volume and thus minimum space for dual pump performance.
The modular design of the SP 100 EC pumps permits the exact configuration of the SP 100 EC-DU with a wide variety of diaphragms, valves and motors according to application-specific aspects. Thus it represents an optimal and economic pump solution for all individual customer demands. In its current version with electronically commutating motor it is also the smallest brushless pump worldwide. Its integrated electronics makes separate selection electronics obsolete.

The success of Retsch Technology’s (Germany) CAMSIZER XT has exceeded all expectations. The analyser, which extends the application range of the well-proven CAMSIZER towards smaller particle sizes and agglomerating materials, has been enthusiastically received by the market. Many new customers in Germany and other countries are using the CAMSIZER XT for applications from a wide range of areas such as construction materials, food or pharmaceutical products. The possibility to analyze not only the particle size (in a range from 1 µm to 3 mm) but also the particle shape is perceived as an important benefit. The various convenient dispersion options allow for perfect adaptation of the analyser to the user’s requirements. The new CAMSIZER XT is characterised by: Precision (Dynamic Image Analysis with wide measuring range from 1 µm to 3 mm, Simultaneous determination of particle size and particle shape, Sensitive detection of oversized and undersized particles), Efficiency (Short measurement times from 1 to 3 min, Measurement results 100% compatible to sieve analysis, Extensive reporting at the push of a button) and Flexibility (Modular design, Dispersion options include air pressure, gravity and liquids and Quick and easy change of measuring module)

Wind Turbines: An Expensive Asset that can Require a Lot of Maintenance
Bearing or gear oil failure can lead to catastrophic failure and older technologies only detected damage after it occurred. The new WearSens from cmc Instruments GmbH (Germany) does just that.
Gearbox damage is the end result of a series of events. The beginning is hairline crack formation and this can be initiated by a number of different factors, too much load, turbine imbalance, transmitted vibration and simply the passage of roller bearings over time.
Once the hairline crack develops, oil then enters this crack, heat and vibration within the crack cause it to degrade into acids and hydrogen, inter alia. The hydrogen then causes embrittlement of the surface around the crack leading to shearing of particles, pitting of the roller bearing and subsequent damage. Corroded bearings, sheared particles and oil quality deterioration contribute to the damage.
Omega’s (UK) new MWTC-D Series of Miniature Portable Wireless Thermocouple Connectors and data logger records over 65,000 process temperature data points and are available in standard J, K, T, E, R, S, B, C, or N thermocouple calibration. Each battery powered, compact connector transmits and/or records process & ambient temperature data back to a mating wireless receiver up to 90 m (300’) away. All readings are displayed on your PC screen in real time using the free provided software. The recording can begin either at power up, or at a pre-set time & date. Multiple wireless connectors (up to 48 units) can transmit to one MWTC-REC receiver. This product is used in chemical, automotive and oil & gas industries to monitor and log temperature process data.

WearSens detects these changes long before the damage occurs. It is a unique condition monitor, online and continuous. WearSens can be used to optimise load versus damage, accurately show additive consumption and predict the need for timely preventative maintenance instead of rigid inspection intervals. Savings result from reduced downtime, accurate oil changes and reduction in abrasive wear.
Applications for the WearSens include wind turbines, high voltage transformers, large gearboxes and lubricant analysis in automotive and marine test benches .
