Custom rotational molding, accessory fittings and custom colors are available. 888/357-3181; www.assmann-usa.com.

BinMaster Introduces Extended Rotary

Extended rotaries for top-of-bin mounting from BinMaster Level Controls are designed for use as a high-level alarm for level detection in bins, tanks and silos. The BMRX and MAXIMA+ genuine fail-safe rotaries feature a de-energized operation that shuts down the motor when material is present to reduce wear and operating temperature for prolonged motor life. 800/278-4241; www.binmaster.com.

Wilden Introduces H400 High-Pressure Pump

The H400 high-pressure, air-operated, double-diaphragm pump from Wilden is designed to transfer viscous, solid-laden slurries at high head pressures. The 1 1/2-inch pump is available with simplex technology to generate up to 250 psig. During operation, only one liquid chamber is used to pump fluid while the other is used as a pressure-amplification chamber, enabling the pump to have a flow rate of 64 gpm with a maximum suction lift of 10.1 feet and the ability to pass solids as large a 5/16 inches. 909/422-1730; www.wildenpump.com.

Trojan Introduces Open Channel UV System

The TrojanUVSigna open channel wastewater UV disinfection system from Trojan Technologies is designed for large-scale disinfection applications. Features include 1000W TrojanUV Solo Lamp Technology, Solo Lamp Driver, staggered inclined lamp arrangement, ActiClean chemical/mechanical sleeve cleaning and built-in module lifting device. 519/457-3400; www.trojanuv.com.

Greyline Offers Differential Level Controller

The DLT 2.0 differential level controller and open channel flow meter from Greyline Instruments Inc. features two non-contacting ultrasonic sensors. One sensor is installed upstream from the bar screen and a second downstream for differential level control. The second sensor also can be installed in a flume to control and transmit differential level control plus flow. The controller includes relays for bar screen rake and level control as well as three 4-20 mA outputs. A backlit LCD display shows level, differential level, flow and total flow. Intrinsically safe sensors and data logger are optional. 888/473-9546; www.greyline.com.

Sodimate Introduces Dust Emission Reducer

The Sodimix dust emission reducer from Sodimate uses powder-activated carbon to eliminate dust created from screw conveyors to slurry tanks. Dry chemical from the outlet chute drops into a wetting/agitation chamber to increase turbidity. Supply water passes through a T-shaped educator and creates a negative pressure that vacuums suspended dust from the outlet chute. On cleaning mode, a valve diverts the supply water through a reversible air/water filter connected to the conveyor outlet. The water cleans the filter and continues to the wetting/agitation chamber. The dust-free system can be mounted on existing systems. 773/665-8800; www.sodimate-inc.com.

Thompson Introduces OVT Pump Series

OVT (oil-less vacuum technology) priming system series pumps from Thompson Pump feature non-contacting internal rotors for greater reliability and longevity. The dry-running pump eliminates the need for oil and associated pollutants and requires maintenance once every 20,000 hours. It also provides flows to 11,000 gpm, high heads to 350 feet and large solids handling up to four inches. The pump is available with electric or diesel drive. 800/767-7310; www.thompsonpump.com.

Electro Static Introduces Bearing Protection Ring

The AEGIS iPRO bearing protection ring from Electro Static Technology is engineered to extend the life of medium-voltage motors and improve system reliability by safely channeling harmful electrical currents away from bearings to ground.
