Hydraulic PumpsDelta Power Company4484 Boeing Drive - Rockford, IL 61109PH Series HIGH PERFORMANCE Hydraulic Gear PumpsDisplacements .499 to 1.403 in³/revFEATURES Pressure Balanced DesignHigh quality diecast aluminum drive and rear sides.Extruded aluminum body.Volumetric Efficiencies to 98%.Low noise levels.Used in BCV Power Units.SAE A Mtg.ShownHIGH VOLUMETRIC AND OVERALL EFFECIENCYDelta pumps produce exceptionally high efficiencies. Zero tip clearances developed during factory run-in, maintainedparallelism between sealing surfaces under all pressure conditions, and low pressure lubrication produce exceptionalvolumetric efficiency.Delta assures maximum mechanical efficiency with PTFE composite bearings in pressure balanced carriers fitted to themain gear bores, thus maintaining proper alignment and concentricity under all operating conditionsThe high mechanical and volumetric efficiencies combine to produce unequaled flow/pressure performance for DeltapumpsDESIGN LIFE/DURABILITYPTFE bearings support the journals on a hydrodynamic film of oil. The low pressure lubrication system provides aconstant flow of oil to cool and lubricate the bearings and journals whenever rotation occurs, regardless of systempressure. This design provides trouble free service when operated within parameters established for speed, pressure,temperature, oil type and cleanliness.RECOMMENDED OPERATING PARAMETERSInlet Vacuum:Hydraulic Fluid:Fluid Temperature:Fluid Velocity:Filtration:Shaft Loads:10 inches Hg maxmum.Must be chosen based on operating temperature. Use oil with viscosity of 45 SSU (6 cSt)minimum and 250 SSU ( 54 cSt) maximum continuous.14 to 176 F (-10 to 80 C)Inlet, 5 ft/sec maximum; Outlet, 20 ft/sec maximum.10 micron.Radial or axial forces on the pump driveshaft are not normally recommended.

HYDRAULIC MOTORSDelta Power Company4484 Boeing Drive - Rockford, IL 61109DM Series Hydraulic MotorDM1 thru DM8 SeriesDM21 thru DM27 Series4F17 Mtg.Shown4F17 Mtg.ShownDM Series hydraulic motors are designed with performance in mind, including: High-strength cast iron bodieswith precision machined filling and trapping grooves, and hardened alloy gears and shafts to run smoothly,special Buna-N o-ring and shaft seals to withstand up to 200 PSI return line back pressure, antifriction bearingsfor 60-70% starting torque, ball thrust bearings to withstand thrust and radial shaft loads, and integral checkvalves to permit bi-directional rotation (to eliminate the need for external case drains). And, they will turn asslow as 300 rpm or lower on low-torque applications.DM Series motors are found in material handling equipment, agricultural implements, snow removalequipment, marine gear and numerous industrial equipment and machine tools as drives for pumps, fans,compressors, mowers and other applications where moderate starting torque and moderate to high speedefficiency is needed.And, because of their design and manufacturing quality, they can be expected to add to the overallperformance and life expectancy of the equipment.Installation Notes:Hydraulic motor controls should be placed on the pressure side of the motor in order to preclude high seal orcase pressures. Return line should be straight to tank.On DM1 thru DM8 series, be especially careful since these units require that the mounting bolts are installed tocomplete the assembly. The two shipping bolts are not sufficient to make the assembly intact and care shouldbe exercised while handling in this condition. Bolt torque requirements are 13 to 17 ft-lbs.WARNING: The specifications/application data shown in our catalogs and data sheets are intended only as a general guide for the product described(herein).
