Lewa: Hermetically tight 170 °C high-temperature pumps for production

Wednesday, December 17th, 2014 by admin Posted in Chemical, In Gerneral, Metering Pumps, Pump Applications

Wacker_freiIn the existing chemical installation in a Wacker Chemie plant, the safety-related design of the relevant pump systems had to be thoroughly renovated. One of the basic requirements for the redesign was that diaphragm pumps themselves had to remain absolutely hermetically tight, even at high working temperatures of +170 °C during normal operations and brief peaks as high as +200 °C. As a result, Lewa developed an individual solution to meet the specific customer requirements.

“As an additional security measure, the pressure-free hydraulic reservoir behind the diaphragm is blanketed with nitrogen as a protective gas”, explains Lewa project lead Rainer Sonnenfroh.

WEG: New frequency inverter for decentralised motor and wall installation

Wednesday, November 26th, 2014 by admin Posted in In Gerneral

WEG2110_Bild1The MW500 frequency inverter with decentralised design has been developed for space-saving solutions, such as directly motor mounted or adjacent to the motor on the wall. As a result, the need for lengthy cables and switch cabinets is eliminated. MW500 is robust with an IP66 protection rating. It can withstand high overloading of 150% for 60 seconds every 10 minutes, and operate in temperatures up to 40°C (wall installation) and 50°C (motor installation). With increased ruggedness compared to alternative technologies, it provides reliable operation over a long service life. The inverter is designed to operate asynchronous motors in the power range 0.75 to 7.5 kW, and is offered as three variants for a mains voltage of 380 to 400V (A: 1.1 to 1.5 kW, B: 2.2 – 4 kW and C: 5.5 – 7.5 kW), and for 200 to 240V, as variant A (0.75 to 1.1 kW). It is ideal for many pump applications.

Mitsubishi: IP55 variant added to inverter series

Wednesday, November 26th, 2014 by admin Posted in Energy Efficiency, In Gerneral, Pump Drives

8-1_Mitsubishi_SPS2014_FR-A846_Next_GenerationMitsubishi Electric has added dust and splash-proof versions with an IP55 protection rating to its FR-A800 series of frequency inverters. Specially designed for harsh environments and tailored to the requirements of pumps, the drives are highly robust and ideally suited for use in industrial and commercial building automation systems as well as in heating, ventilation and air-conditioning systems.  The new FR-A846 series with an IP55 protection rating represents Mitsubishi Electric’s latest drive technology in the output range from 400 watts up to 160 kW. The drive’s EMC filter built in as standard ensures full compliance with the EMC Directive (EN 61800-3, 1st environment, category C2) while its DC reactor – also built in as standard – ensures full compliance with IEC 61000-3-12 for reducing and limiting harmonic currents so that separate certification is not required. The FR-A846 also has a built-in main switch version with locking option.
