Drive Sprocket
JMS drive sprockets are designed and fabricated with stainless steel sprocket hub and UHMW-PE sprocket teeth. Our component selection ensures the drive sprocket works optimally and accurately engages the drive chain.
Shaft Connections
JMS shaft connections are the standard for all flocculators. These connections utilize bored blind flanges with special welds for added strength. Each flange is grooved to the correct diameter and surface milled to parallel for strength and proper alignment.
Bearing Assembly
The JMS bearing assembly is designed to be durable and have a low life cycle cost. JMS Mega-FLOC (HPWF) uses submerged journal bearings that are manufactured with split cast stainless steal housings with UHMW-PE liners which allow for water lubrication.
A Powerful Train
In no area is JMS knowledge more evident than in the Mega-FLOC (Horizontal Paddle Wheel Flocculator) drive train with integral chain tensioning. Selection of materials of construction and use of the JMS proprietary design program optimize performance and minimize maintenance costs over the system’s life cycle. Having sold more Horizontal Paddle Wheel Flocculator than any other supplier, use of JMS know-how determines optimal gearmotor horsepower requirements using the desired velocity gradient, system efficiencies, and safety factors. The industry leading choice of SS for the drive sprocket hub, non-metallic UHMW-PE sprocket teeth, and specialized SS chain are JMS enhancements that utilize the latest in technology, for trouble free continuous operation. Drive trains are available in wet chain, dry chain, and direct coupled options.
A Look in the Shaft
Proper sizing, material selection, and internally developed manufacturing processes add to the quality of each JMS Mega-FLOC (Horizontal Paddle Wheel Flocculator). Solid 17-4 stainless steel (SS) spool shafting at the bearing points utilizes bored blind flanges with special continuous fillet welds on both sides of the flange. A minimum of four gussets are installed for additional reinforcement. Pipe shafts, between bearings, are connected with blind flanges grooved to the correct diameter for precise alignment and joined by a continuous watertight weld. Attention to detail demonstrated after fabrication by surface milling of all flanges to parallel, eliminates stress risers and cyclic fatigue.
Getting Your Bearings
The Mega-FLOC (Horizontal Paddle Wheel Flocculator) design features proprietary split cast SS journal bearings with UHMW-PE or bronze liners (for high grit applications). This component selection offers each plant the aesthetic appearance, low life cycle costs, and durability they are looking for. All bearing assemblies come mounted on a base plate with proprietary leveling assembly for accurate alignment.
