2 GC and D Series Rotary Gear Flow Dividers Intensifier - Combiner (European and U.S. Versions) Field-proven Concentric Hydraulic Systems’ Rotary Gear Flow Dividers are providing efficient, reliable service for a wide variety of applications in agricultural, materials handling, and construction equipment. These hydraulic flow dividers provide many useful functions from a single pump source: • Synchronized operation of multiple cylinders or fluid motors. • Proportional division of pump output among several circuits. • Intensified pressure when pressure higher than pump capacity is needed. WHY ROTARY GEAR FLOW DIVIDERS INSTEAD OF SPOOL TYPE DIVIDERS? Connected within the hydraulic circuit, rotary gear flow dividers operate automatically and only when needed. They require no maintenance. In a rotary gear divider, horsepower-in is equal to horsepower-out with very small efficiency losses. Consequently, it does not generate heat. Since the efficiency of the unit is a function of the pressure drop across the section, efficiencies approaching 98 percent are not uncommon. This enhances the overall system effectiveness. Spool type dividers require a significant pressure drop just to operate. Heat is designed in when spool type dividers are incorporated in an application. Much care has to be taken to accommodate the inherent inefficiencies of spool type dividers when sizing them for an application. Rotary gear flow dividers are also more tolerant of contamination and more rugged than spool type flow dividers. Spool type dividers can be accurate and exhibit little internal leakage but their cost is generally as much as 25% greater than comparable rotary gear dividers. DIFFERENTIAL RELIEF VALVES Our modular design allows us to add differential relief valves in each section of our flow dividers. These valves are not system relief valves. They are commonly used in applications where cylinders must be synchronized. They also serve to protect the flow divider against excessive differential pressure in the divider which could be caused by actuators becoming stalled or restricted. APPLICATION OF A ROTARY GEAR FLOW DIVIDER IN A CYLINDER CIRCUIT Rotary Gear Flow Dividers are designed to synchronize hydraulic cylinders (bring them to equal stroke length) in one direction only. This needs to be in a direction where the cylinders bottom out (go to the end of their stroke). The synchronizing is accomplished because excess fluid is bled off over the flow divider’s internal relief valves to feed the cylinder that is late getting to the end of it’s stroke. Reversing the direction of the cylinders, the Rotary Gear Flow Divider will act as a combiner with the same efficiency as a divider. Please note that a combiner doesn’t regulate cylinder speed, so a flow control is required to limit maximum flow. ROTARY GEAR FLOW DIVIDER USED AS AN INTENSIFIER Press and clamping circuits that require high flow at low pressure and low flow at high pressure are good applications for Rotary Gear Flow Dividers to intensify pressure. High flow from the outputs of the divider are combined until high pressure is required, then one or more of the divider outputs are dumped to tank giving high pressure in the intensified circuit. Caution is required so that the pressure does not exceed the rating of the flow divider. WHAT’S NEW AND INNOVATIVE ABOUT CONCENTRIC ROTARY GEAR FLOW DIVIDERS? We have earned a reputation over the last 80 years as innovators and systems specialists. We go beyond the basic requirements for hydraulic components to analyze the total system goals. In doing this, many times we find that we can help solve a customer’s system problem by doing something different to our product. The following are examples of how we have done this with flow dividers: SOLENOID ACTUATED 2-WAY VALVES FOR FLUID MOTOR DRIVE APPLICATIONS This feature provides operator selection between a positive traction drive or differential drive on turf care vehicles, small utility vehicles and various mobile lift devices. This feature is available in 2, 3 or 4 section dividers. ADJUSTABLE NEEDLE VALVE BETWEEN SECTIONS to allow only the set amount of flow providing the desired differential effect for drive motors. It can also be adjusted for varying tire ratios. WHY CONCENTRIC VS. OTHER ROTARY GEAR FLOW DIVIDERS? Concentric GC series flow dividers are of cast iron construction with 1/2” diameter shaft and needle bearings for high pressure operation. The gear bores are held to extremely close tolerances to provide maximum efficiency. They are lighter weight than many competitors because no interface plates are required between sections. This feature also insures better shaft alignment and fewer leakage paths. Seal plates between each section provide additional insurance against leakage. The modular design easily accommodates multiple gear width combinations and multiple porting options. Concentric D series flow dividers incorporate the above features but substitute a 5/8” diameter shaft and needle bearings. The D series also substitutes o-ring seals between each section for enhanced sealing. INSIDE THIS CATALOG ...

The curve shows speed vs. flow per section. For equal sized sections: Assume four section dividers with a total flow of 12 GPM (45.4 L/M) in and 3 GPM (11.4 L/M) per section out. From the chart, an order code 12 or 20 would be suitable for this flow. However, the nearer the mid-range, the better the efficiency. From the curve, order code 16 crosses the 3 GPM (11.4 L/M) line at 2750 RPM. The best selection is the order code 16 gear section. For proportional flow, the curve is used as follows: Assume a four section divider with an input flow of 19 GPM (71.9 L/M) and an outlet flow of 7 GPM (26.5 L/M) , 5 GPM (18.9 L/M), 4 GPM (15.1 L/M), and 3 GPM (11.4 L/M). With a straight edge on the 3000 RPM line, proper flow for 7 GPM (26.5 L/M) is given with an order code 32 gear section, 5 GPM (18.9 L/M) with an order code 24 gear section, 4 GPM (15.1 L/M) with an order code 20 gear section and 3 GPM (11.4 L/M) with an order code 16 gear section. The chart above also shows the allowable differential pressures. The differential relief valve setting is determined by the maximum pressure needed by the circuit minus the inlet pressure without exceeding the allowable differential pressure. Either the continuous or intermittent differential pressures are used, depending on the circuit requirement.

4 The curve on the left and the chart above can be useful in selecting the proper size flow divider sections. The curve shows speed vs. flow per section. For equal sized sections: Assume two section dividers with a total flow of 16 GPM (60.6 L/M) in and 8 GPM (30.3 L/M) per section out. From the chart, an order code 16, 20, 24 or 28 would be suitable for this flow. However, the nearer the mid-range, the better the efficiency. From the curve, order code 20 crosses the 8 GPM (30.3 L/M) line at 3200 RPM. The best selection is the order code 20 gear section. For proportional flow, the curve is used as follows: Assume a three section divider with an input flow of 20 GPM (75.7 L/M) and an outlet flow of 10 GPM (37.9 L/M), 7 GPM (26.5 L/M), and 3 GPM (11.4 L/M). With a straight edge on the RPM line, note the 10 GPM (37.9 L/M) line at 2800 RPM gives the proper flow with an order code 28 gear section, an order code 20 gear section and an order code 08 gear section. The chart above also shows the allowable differential pressures. The differential relief valve setting is determined by the maximum pressure needed by the circuit minus the inlet pressure without exceeding the allowable differential pressure. Either the continuous or intermittent differential pressures are used, depending on the circuit requirement. The differential relief valve is adjustable through a range of 500 - 1000 PSI (34.5 - 69 BAR). Our standard setting for the differential relief valves is 750 PSI (51.7 BAR).

Pump shaft alignment is key to preventing unnecessary wear and damage to the pump shaft seal and bearing. Improper alignment may lead to premature pump failure. Also to be considered are unwanted torsional resonant frequencies in the system which can quickly cause damage to components in the drivetrain and reduce system life and performance. Improper pump installation can lead to premature failure, increased maintenance costs and reduced production levels of final product. jbj Techniques can advise on the correct installation of into Industrial / hydraulic pumps mobile / marine / machine tool / agricultural / offshore industries and can specify complete driveline systems from their extensive range of components which are available from stock or manufactured to order, albeit simple or complex, standard or bespoke. Electric Motor – Hydraulic Pump Adaptors (safe area) jbj Techniques Limited offer the most comprehensive range of in Europe. bellhousings Designed to connect electric motors with frame size IEC D56 - D400 (0.06kW – 750kW) and can be compatible with electric motor 'B5' or 'B14' flange configurations.

Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level. With a vast array of components to select from, jbj are well placed to provide all required components to support the required cooling system.
