EQUIPMENT FOCUS CONVEYING MATERIAL HANDLING PUMPS Replaceable tips reduce waste save time In a move designed to reduce landfill waste from worn out conveyor belt cleaners while reducing the labor time and safety risks associated with blade changeouts Martin Engineering has launched a new family of replaceable tips to maximize the amount of usable material on each cleaner blade The tips were introduced in direct response to customer input They have increased wear life in secondary cleaners by as much as 50 percent while cutting replacement labor time roughly in half Because the new tips are pinned in position and require no hammers or other tools to remove and replace the risk of injury during service is significantly reduced The blade mounting system also underwent a redesign with a single pin configuration to simplify replacement The new tips can be replaced by hand without tools improving safety and cutting the service time to just 15 minutes the company says Pumps engineered for harsh environments The STS Series pumps by Franklin Electric are designed for harsh environments offering durability and abrasion resistance in every application A submersible turbine pump STS offers premium ductile iron bowls discharges motor brackets investment cast 304SS impellers lengthened bronze discharge bearing bronze motor bracket bearing and other custom options The STS Series units are designed for irrigation industrial commercial or municipal submersible water pumping applications www franklinwater com New brake designed to come through in a clutch Force Control Industries Size 30 Posidyne clutch brake with oil shear technology can be operated as a clutch only for applications such as pumps or fans or as a clutch brake for cycling or indexing applications This smooth and quiet brake dynamically accelerates or decelerates high inertia loads without wear on friction discs the company says The unit consists of seven basic components including the input shaft which is connected to the motor or engine the output shaft which is connected to the load a clutch and brake stack consisting of multiple alternating friction discs and drive plates and a centrally located piston between the brake and clutch that will engage either the clutch or the brake but will never overlap to engage both at the same time www forcecontrol com www martin eng com Pulleys made with natural rubber Baldor Electric Co s Dodge D LAG conveyor pulleys utilize a natural rubber compound that is 73 percent more resistant to wear than standard styrene butadiene rubber the company says The lagging is 100 percent vulcanized for pulley bonding and strength making it resistant to cuts and gouges Two pulley styles are available D LAG heavy duty drum pulleys from 10 in to 24 in in diameter and D LAG MDX mine duty drum pulleys from 12 in to 24 in in diameter www baldor com Pumps designed for energy efficiency Wildens Pro Flo Shift air distribution system is designed for use in Advanced Series bolted and Original Series clamped AODD pumps The systems design does not require any additional bolted on equipment or bulky electronics It is available in 15 in 2 in and 3 in sizes and features maximum discharge pressures to 125 per square in gauge maximum flows to 243 gallons per minute and a maximum solid handling size to 05 in www wildenpump com 58 PIT QUARRY April 2014 www pitandquarry com
