FLOW DIVIDERSDelta Power Company4484 Boeing Drive - Rockford, IL 61109Delta Power Rotary Flow Divider, Positive DisplacementWhere one pump operates anumber of hydraulic motors: carwash systems lubrication systems(multiple point), hydraulic motordrivenmachines,(harvestingmachinery, etc.) High-strength permanent mold cast iron housingPrecision needle bearingsPrecise machined trapping relief grooves provideconstant filling and discharging to assure quietoperation and maximum bearing life.O-ring seals between sections (Buna-N)Delta Series P geared flow dividers, accurately divide flow from a single hydraulicsource into two or more equal or proportionate circuits. In like manner, the inputpressure required will be proportional to levels of flow/pressure out of the flow divider,rather than at the highest pressure level, thereby saving what would normally bewasted energy. Proven design, stable material selection and precision machining arethe Delta keys to reliable performance you can depend on in a variety of applications.Where two or more cylinders mustbe synchronized: lift platforms,scaffolds, presses.Application Suggestions1. For greatest efficiency and accuracy, flow dividers should be used at nearmaximum rated inlet gallonage. For quieter operations, lowered RPM shouldbe considered.2. Maximum (3500) and minimum 500 RPM; inlet pressure ratings and differentialpressure ratings should be followed.3. Provide over-pressure protection (relief valves) in each circuit.Where main pump pressure must beintensified in one circuit of multiplecircuit machinery, such as wastecompactorsandotherhi-loapplications.4. When designing flow dividers into a static circuit, remember that they aredynamic devices which do nothing while static.5. Use SAE 10 through SAE 30 industrial petroleum-based hydraulic oil with 200SSU viscosity; filter to 25 microns.6. Do not use teflon tape in installation. Use plastic pipe sealant with NPTF ports.Where two or more circuits must becontrolled independently at differentpressures: presses, machine tools,etc.WARNING: The specifications/application data shown in our catalogs and data sheets are intended only as a general guide for the product described(herein).

FLOW DIVIDERSDelta Power Company4484 Boeing Drive - Rockford, IL 61109Application DataThe Delta flow divider is a positive displacement flow dividing or proportioning apparatus. It will divide the flow from onesource into two or more equal or proportionate circuits, and intensify or reduce the pressure level as required. Note thatthese flow dividers will operate in reverse in a combine mode, but in that mode, the accuracy likely would be significantlyreduced.In its basic configuration, the unit consists of a number of inter coupled gear type hydraulic pump motors. Each sectionmust be capable of performing the pumping or motoring function. The section have a common inlet and separate outlets.Fluid from a prime source, such as pump, supplies the motive power to the flow divider. No energy is added to the fluid inthe device, although each outlet may have an energy level difference than any other section. When the sections are of likesize, the function is to divide the total flow into equal increments of flow, and when the sections are of unlike size, thefunction is to divide the flow into proportionate increments relative to the chosen geometric displacements.Since the flow divider is a positive displacement machine, it will accomplish its function over a wide range of pressure ofviscosity differentials. Nevertheless, certain limits are imposed due to slip characteristics and torque losses in themachine. Therefore, the performance criteria in this paper will be developed around a unit of average tolerance allowance.The data, so derived, will be averaged. Be aware that these units can require a certain amount of break-away pressure. Itis recommended that operation at low pressures ( 100 PSI) is not attempted without consultation with the factory.General RelationshipsIn any unit, neglecting any losses, there exists the relationship thatQi Q1 Q2 . Qn;Where Qi is the flow into the unit and Q1, Q2 and Qn are the displacements out of each section. Since no energy is addedand if none were lost, it follows thatPiQi P1Q1 P2Q2 . PnQn;Where Pi is the pressure into the unit and P1, P2 and Pn are the pressure levels out of each section.In a unit consisting of any number of/or sizes of sectionsPi P1Q1 P2Q2 . PnQnQiIn any actual case, the above theoretical observations must be corrected to encompass the pressure drop and slip lossesin the flow divider. The pressure drop is primarily a function of the amount of fluid and viscosity. At the usual viscosities(100 to 300 SSU) encountered in hydraulic systems, the pressure drop Pp, can be approximated by the relationship,where n is the number of sections, PP 6Qi 25nSince the flow divider itself is a parallel circuit, the actual pressure Pia into the unit isPia P1Q1 P2Q2 .

Determine the size of the sections that will best give the required flow and pressure. The displacement from eachsection will be the fractional proportion of the sectional displacement versus the sum of the displacements of allthe sections. That fraction multiplied by the input flow gives output displaced by each section.2. Determine Pp from PP 3. Determine Pia from Pia 6Qi 25nP1 Q1 P2 Q2 . Pn Qn PPQ14.
