The latest blower package available from Aerzen USA features a three-lobe design that makes possible a patented pulsation cancellation technology capable of eliminating 97% of pulsations right at the source. This design reduces piping noise and vibrations typical of water/wastewater treatment plant blowers. The new blower package are distinguished by compactness and accessibility to all components. They employ automatic belt tensioning without an operator interface or spring adjustment. Standard packages range from 25 to 8,500 cfm. Each is performance tested. Most are available for delivery from stock. All are warranted and backed with full technical support.

Brunel Safety Element Torque Limiters provide immediate disconnection from the driving side of a chain and flight system during jams and periods of excessive loading. This can prevent damage and destruction of the drive chain and flight bars. The torque limiter features 316 stainless steel construction and improved sealing capabilities, which provides an unlimited life on the non-wearing components. The wearing components are hardened to a minimum of 62 R/C providing an extended life to the wearing components. The safety element offers a torque range from 338 lb in to 60,000 lb in with a bore size range from 1'' to 3.75'' on the standard sizes. The torque limiters are offered in three different styles. The internally adjustable safety element is tamperproof. The externally adjustable safety element can be field adjusted. The disconnect cam safety element allows for manual disconnection, replacing the need for a jaw clutch.

The Flowserve Mark 100 globe control valve delivers higher capacity in a smaller valve than similar conventional valves in sizes 6"-16" and pressure classes 150-600 psi. A wide, streamlined gallery increases capacity an average of 15% over competing valves (e.g., tested capacity for 10" Mark 100 comparable to catalog capacity of others' 12" valves). Available with a full range of noise and cavitation reduction severe service trims, the valve is applicable to a range of industries. It uses longer strokes than any competing solution, enabling precise flow — even under rigorous demands.
