Continuous pulpers

The Hydrapulper from Thermo Black Clawson is designed for continuous operation in high tonnage systems that require stock defibering only to the extent that it can be extracted through a given hole size. Continuous pulpers range in typical sizes from 12 in. to 27 in. in diameter (up to 5,200 ft3 stock volume) with capacities up to 1,400 tpd. All continuous Hydrapulper designs feature under-rotor extraction through a bedplate with holes that are extended beyond the outer diameter of the rotor.

Software program

The RPM AC Motor Wizard software program from Rockwell Automation is designed to perform highly complex motor selection tasks that, in the past, have only been done manually by motor design engineers. A base program contains information concerning the operating characteristics of selected motor modules/frames in the form of a reference database. The data contained in this program pertains to design criteria.

Lift trucks

The new 7-Series lift trucks from Toyota Industrial Equipment feature the revolutionary System of Active Stability (SAS). Toyota’s patented SAS improves safety and productivity through advanced technology. This advanced technology helps reduce the risk of tip-overs and spilled loads by increasing the stability of the truck. The 7-Series trucks are available in 4,000-lb to 6,500-lb capacity cushion tires and 300-lb to 6,500-lb capacity pneumatic tires.

Soy polymers

Pro-Cote soy polymers from Protein Technologies International are chemically-modified protein polymers designed for use as rheology modifiers, co-binders, and structuring agents in paper and paperboard coatings. The polymers are supplied in dry powder form and can be added directly to pigment slurries during makedown or made into a separate solution for blending into a coating. They can be used in size press, precoat, and topcoat applications with any applicator type.

Laboratory filters

Osmonics has released its new product catalog for filters, filter devices, and accessories used primarily in the laboratory industry. The comprehensive catalog features a wide range of products addressing the needs of researchers in a broad range of applications. The 90-pg. catalog details product specification and ordering information. To help in selecting the best product for an application, there are several product selection charts organized by sample volume, and products used by market/industry in specific applications.

Butterfly valves

Apollo 130/132 Series all purpose butterfly valves offer maximum flow coefficients. Model 130 valves are wafer-style; Model 132 models are companion lug designs. Both are rated 150 psig with standard stainless steel disc. They provide bubble-tight shut-off between flanges. The design isolates valve stem and body from flowing media and provides a valve with no pockets and superior abrasion resistance.

Linearization software

ExperTune’s new software provides linearization for any pH loop resulting in pH control with little or no cycling. Better pH control improves product quality, reduces reagent costs, and helps to keep pH within regulation limits. ExperTune calculates the characterizer that should be applied to both the measurement and set point of the pH loop. The linearized pH measurement can then be accurately controlled by a traditional PID controller.

Stump and log shear

The Megabyte excavator attachment from Bandit Industries is specifically designed to break down stumps and oversized logs into manageable pieces that can be more efficiently processed through waste reduction equipment. The Megabyte will also act as a stump puller that will split stumps while still in the ground, eliminating the need to dig around the stump for removal, as in the case when using a conventional backhoe bucket with a finger.

Sealless pump

Flowmotion positive displacement industrial pumps are extremely simple, as well as reliable. They are capable of pumping a wide range of materials, including high solids streams and abrasive slurries. Pump capacities range from 5 gpm to 300 gpm., and pressures range up to 300 psi.

Drain valve

The original Ram Type drain valve from Strahman Valves features a fully retractable piston that allows for free flow when opened. It extends into the vessel when closed to prevent clogging by dislodging accumulated sludge. The valve is equipped with stationary sealing rings to prevent leaking and automatically clean the piston. It also features a cast body and is available in hand, hydraulic, air, or air-motor operated models.

Bearings

Graphalloy graphite/metal alloy bushings from Graphite Metallizing are self-lubricating and work in low lubricity, corrosive and sour liquids, and high temperature conditions. Used in pumps, conveyors, duct damper flange assemblies, agitator shaft bearings, and submerged washer bearings, Graphalloy wear parts result in lower operating and repair costs and provide assurance against catastrophic failures.

Gravity filters

Nash BSW gravity filters are non-pressure devices that remove suspended solids from high flow water streams up to 4,200 gpm. They are most commonly used to remove felt hairs, fiber bundles, and process debris from recycled plant water. Nash BSW gravity filters continually lift solids out of the screen and minimize the potential for plugging.
