38 • ROCK products • September 2017 EQUIPMENT & TECHNOLOGY PUMPS & MOTORS Baldor Electric Co. announced the expansion of the Raptor tire coupling product line, designed to deliver up to 5.9 times longer coupling life, to include sizes E100, E120 and E140, with a max- imum torque rating of 340,340 in.-lb. The Raptor coupling utilizes patented WingLock technology, an optimized elastomeric element designed to pro - vide longer driven equipment life and increased reliability. This technology increases surface area at the most crit- ical regions of the element, resulting in higher bond strength, improved fatigue resistance, and significantly longer coupling life than competitive urethane designs, according to the company. A non-lubricated natural rubber element results in lower stiffness, improved vibration damping and indus- try leading misalignment capabilities. For reduced maintenance, the Raptor offers a split element for easy replace- ment without having to move or re-align connected equipment. Slotted clamp ring holes offer extra clearance for mounting hardware, resulting in a noticeably easier installation. Suitable for a broad range of industrial applications, Dodge Raptor couplings are third party ATEX certified for use in hazardous environments. Raptor ele- ments are also available as an armored element that exceeds ASTM 1149-07 rubber deterioration standards for use in extreme environments. Available in both close-coupled and spacer designs for a wide range of ANSI and ISO shaft gaps, Raptor couplings are offered with Taper-Lock and QD bushed or finished bore hubs, with bore sizes up to 9 in. and a torque range up to 340,340 in.-lb. Every Dodge Raptor cou- pling is backed by an industry leading five-year warranty. Baldor, BJM Pumps Built for Most Difficult Pumping Challenges High-capacity hard metal submers- ible slurry pumps with agitator by BJM Pumps are a perfect choice for industries that face the most difficult pumping challenges. The KZE Series of pumps feature: •  Sealing System – Oil cooled and lubri- cated double mechanical seal design with SiC vs. SiC faces and Buna N elastomers. Seal chamber protected from pumpage by labyrinth rings and lipseal. Seal Minder leak-detection probe. • Bearing System – Permanently lubri- cated upper and lower bearings with high temperature grease to extend life. Upper radial bearing is roller bearing design. Lower radial and axial thrust bearing is double row angular contact design. •  Impeller – Semi-open hard metal slurry type impeller capable of pass- ing 1-in. solids to accommodate heavy slurry loading. • Agitator – Hard metal agitator keeps heavy solids from settling and allows them to be pumped away. • Pump Materials of Construction – 28 percent high chrome iron wear parts (volute, impeller, wear plate). - 403SS shaft and impeller key. - 304SS hardware & fasteners. - Cast iron motor housing. - High chrome iron agitator. Motor Features: • Power Cable – 50-ft. length standard, GGC cable with Zener diode for use with ground check controls. Conduc- tor size AWG #6 (50 hp) and AWG #4 (75 hp). •  Sensor Cable – 50-ft. length for Seal Minder moisture sensing probe and motor thermal sensors. •  Cable Entry Sealing System – Com- pression fitting with Buna N grommet. Individually isolated and potted leads to prevent moisture intrusion and wicking. • Class H insulation. • 1.15 Service factor. •  104 F (40 C) max liquid temperature. • 4 pole motor speed.
