Two new NLB 3750 3-D tank cleaning heads from NLB Corp. feature a redesigned hub assembly that triples the seal life of previous models and greatly simplifies seal replacement, reducing downtime. Both deliver the 3-D cleaning action made popular by previous NLB models, with rotating high-pressure water jet nozzles mounted on a revolving head to maximize interior coverage in tanks and reactors. The NLB3750-85 operates at from 4,000 to 13,000 psi (275 to 900 bar) with a flow rate of 80 gpm (302 lpm). The NLB3750-110 operates at from 4,000 to 8,000 psi (275 to 550 bar) and 110 gpm (416 lpm). Both have stainless steel bodies for durability and ease of cleaning. High-pressure water jets remove chemical and resin build-up from tanks and reactors faster and more thoroughly than manual methods, while eliminating the need for anyone to enter a confined space. They are environmentally-friendly, since they use nothing but water. NLB offers a range of 3-D tank cleaning heads from 3,000 to 20,000 psi (210 to 1,400 bar), with a variety of arms, telescopic lances and related accessories to suit a variety of applications. NLB Corp. is a leader in high-pressure and ultra-high pressure water jet technology. The company manufactures a full line of quality water jetting systems and accessories for contractor and industrial uses, including product removal, surface preparation, tank and tube cleaning, concrete hydrodemolition, concrete and pipe cutting, and more.
