Hydrapulpers are designed for specific applications and are based upon furnish, capacity, and operational needs. Our rugged and reliable units are installed in over 8,800 locations across the globe and are proven in a variety of applications and on a wide range of furnishes. The DR Series is the innovative, world-class version that features the “D-style” tub for improved bale submersion and raised rotor design for better debris handling and longer rotor life.
Preferred by operators across the globe for its’ continuous operation and system stability, this energy efficient system removes contaminants intact for easy disposal. High trash levels are handled in stride regardless of input rate.
This built-to-last pulping system is the latest generation offering increased pulping efficiency in high consistency applications. With low horsepower demands that result in lower operational cost, it also offers superior ink dispersion and low contaminant attrition for very efficient pulp processing.
The newest generation in performance pulper rotors, the power-saving Vortech was developed using the latest in computational fluid dynamics, rigorous real-world testing, and years of industry-leading experience. Utilizing key face angle and lift features, this best-in-class dynamo comes sized and configured to best match your system and requirements.
The rugged heart of HydraFlow Continuous Detrashing System is this durable detrasher, capable of producing a constant output of low-density, light-weight rejects. It works with the Hydraflow Trash Pump, alongside traditional continuous pulpers, to increase pulp yield, prevent water waste, and protect downstream equipment.
An integral part of the Hydraflow Continuous Detrashing System, this high-pressure unit efficiently moves rejects onward to the detrasher for further processing. The pump’s small footprint is perfect for installation into tight locations.
Hydrapurge Detrashers are designed to extract the stock from a pulper to entrap and concentrate contaminants. The stock is passed through the detrashers extraction plate and then sent forward for further processing. Heavy and light contaminants are retained, washed, and dumped. They are available is several sizes and styles to match the needs of your pulping system.
The Scavenger removes both lightweight contaminants and heavy trash from pulpers and is available in continuous and batch processing versions. These low-maintenance units, which can replace most existing junkers, also provide additional defibering and wash useable fiber from the extracted contaminants.
This non-vibrating, low attrition tailing screen removes coarse debris and recovers water from reject loop. This rugged workhorse maximizes stock recovery and dewatering of light rejects and is excellent for both batch and continuous operation.
The slotted drum screen is a non-vibrating, low attrition tailing screen that removes debris normally found in the coarse screening loop of most fiber recycling mills. Ideally suited for processing rejects from a Kadant Float Purger™ stock cleaning system or anywhere a non-pressurized tailing screen device is used.
The UltraSorter is a non-vibrating, low attrition, totally enclosed tailing screen that removes debris normally found in the coarse screening loop of most fiber recycling mills. It is ideally suited for processing rejects from a Kadant Black Clawson Float Purger™ Stock Cleaning System. The UltraSorter can also be installed in secondary fiber, paper machine approach flow, and pulp mill screening systems.
The grapple hoist effectively removes waste material from the pulper junk tower. Constructed to provide superior performance and long service life, the grapple features individually driven tines and a rugged rotator for optimum adaptation to handling a variety of materials.
The stainless steel trashwell is available in 4-feet or 6-feet diameters.
The Ragger is designed to remove trash and bailing wire that results from slushing secondary fiber furnishes. It makes quick work of snagging sheet plastic, rags, wet strength paper, and other light trash normally encountered in waste paper furnish.
Used to chop the rag rope into shorter sections for easier disposal, this unit features a double-cylinder guillotine design with replaceable hardened steel knife blade and anvil. The hydraulic system includes a 15 HP motor and pump capable of developing 3,000 PSI pressure.
The STR valve is severe-duty stainless steel knife gate valve for use with our Liquid Cyclone Cleaner and in other high and medium density cleaning and detrashing systems such as our Hydraflow. Their rugged construction makes quick work of high concentration contaminants such as glass, sand, staples, nuts, bolts and other hard debris.
