Cleaners of in-situ and onshore fish farming pen nets require reliable, effective water jet cleaning systems to remove algae, waste matter and other organic growth that restrict water flow and water quality, affecting fish health, growth and harvest yield.
NLB’s 225 and 325 Series water jetting pumps are specifically designed for the demanding rigors of net cleaning in the harshest of environments. Extremely reliable, proven pump systems provide up to 4,000 psi (275 bar) of trouble-free, low-maintenance performance. These units can be easily integrated with many existing net cleaning head systems.

Easily integrated with industry-leading cleaning head systems
Commonality of system components between horsepower ranges
The Tassie Devil Tracker 4000 is designed to clean all cage netting irrespective of net inclination and degree of fouling in a single strike.
The cleaning system comprises a remotely operated vehicle (ROV), hydraulic hoses and drive unit. The ROV receives its power hydraulically from the drive unit located on the service craft.
The Tracker 4000 is manoeuvred via a controller much like an Xbox game controller to provide familiarity to the operator. The ROVs motion is relayed by camera to a pair of LCD monitors situated on the service craft.
Net cleaning is achieved via the patented high torque, slow action scrubbing blades on the ROV which may be configured to optimise net cleaning for various environments.
The Tassie Devil 4000 is operated by winch and complements the Tassie Devil Tracker 4000 by cleaning external cage netting in the heavy fouling zone 6-8 metres before the hard line. The Tassie Devil 4000 possesses much of the patented componentry observed in the Tracker 4000 but with the net cleaner winched from the service craft rather than remotely operated. Like the Tracker 4000, net cleaning is achieved via the patented high torque, slow action scrubbing blades on the ROV.
