Safety relays
Phoenix Contact now offers PSR safety relay modules specially designed for process applications with optimized startup behavior approved to SIL3 / IEC 61508. Until now, conventional safety relay modules have had a very high startup current that the control system interprets as a short circuit. The PSR modules provide two safely isolated redundant normally open contacts and one normally closed contact that can switch up to 250 vAC/6A in a 22.5 mm housing. These compact safety relays are used to electrically isolate field applications from the control system or to adjust the voltage or power. In addition to being used in safety-oriented control systems, these relays form an integral part of the safety chain for electrical and electronic applications in process technology and mechanical engineering.

Centrifugal pumps
Magnatex Pumps offers its MMP Series Pumps, designed specifically for low-flow, low-head applications. These magnetically driven, sealless centrifugal pumps provide efficient, leak-free pumping of flows from 1/2 to 20 gpm, heads to 90 feet and pressures to 85 psig. The pumps use the company's exclusive "straddle bearing" design which reduces shaft load and bearing wear. They are furnished with shaft, thrust ring, sleeves and bushings made of Beta sintered silicon carbide material.

Pressure transmitter
Viatran has launched the WW517 submersible pressure transducer for wastewater applications. The unit is a 316L liquid level transmitter with a 3" diameter opened faced Teflon coated sensor. It is designed for instances where the media is "sludgy." It features all welded transmitter construction and ranges down to 27" WC. The transmitter can be calibrated remotely using the optional HART protocol. The all-welded sensor design eliminates the need for an O-Ring seal, thereby eliminating potential leak paths.

Redesigned pump
LMI Milton Roy has redesigned its Series A pump. Maintaining the same size footprint of previous models, the new pump offers a number of enhancements. The newly redesigned housing improves the drive's heat transfer properties, as it generates heat farther away from the electronic components to maintain the long-term integrity of the PC Board. Electrical connector attachments have been repositioned to the front of the pump for access.

Oil/water separator
ecoSep®, from Royal Environmental, is a below grade oil/water separation unit that can help keep water clean from oil contaminants. The unit permanently separates oil from water and allows virtually no oil emulsion formations to develop. The system is designed for use in point-source and industrial stormwater applications and requires no external energy supply. Full access to all major components allows for cleaning and maintenance. An automatic shutoff valve (ecoStop) provides protection against unexpected spills or maintenance neglect when maximum oil storage capacity is reached or when a certain liquid level is exceeded.
