4 General Information Overview The TurollaOCG Group 3 is a range of peak performance fixed-displacement gear pumps. Constructed of a high-strength extruded aluminum body with aluminum cover and flange, all pumps are pressure-balanced for exceptional efficiency.

5 General Information Pump design SEP3NN The SEP3NN gear pump is available in a limited displacement range from 22. to 44.1 cm 3 /rev [from 1.34 to 2.69 in 3 /rev]. Suitable for applications where the pressure is lower than 21 bar [345 psi], the SEP3NN range is released into SE and European configurations. The overall length is reduced by 12 mm [.47 in] in respect of the SNP3NN. SNP3NN The SNP3NN is available in the full displacement range from 22. to 88.2 cm 3 /rev [from 1.34 to 5.38 in 3 /rev], and with higher pressure ratings than the SEP3NN. This is due to the pressure balance on each side of the gears obtained with pressure-balance plates made in antifriction alloy that contribute to high volumetric efficiency and maximum sealing as well.

10 System Requirements Pressure The inlet vacuum must be controlled in order to realize expected pump life and performance. The system design must meet inlet pressure requirements during all modes of operation. Expect lower inlet pressures during cold start. It should improve quickly as the fluid warms. Peak pressure is the highest intermittent pressure allowed. The relief valve overshoot (reaction time) determines peak pressure. It is assumed to occur for less than 1 ms. The illustration to the right shows peak pressure in relation to rated pressure and reaction time (1 ms maximum). Rated pressure is the average, regularly occurring, operating pressure that should yield satisfactory product life. The maximum machine load demand determines rated pressure. For all systems, the load should move below this pressure. Inlet pressure Max. continuous vacuum.8 [23.6] bar abs. Max. intermittent vacuum.6 [17.7] [in. Hg] Max. pressure 3. [88.5] Time versus pressure Pressure Peak pressure Rated pressure Reaction time (1 ms max) Time System pressure is the differential of pressure between the outlet and inlet ports. It is a dominant operating variable affecting hydraulic unit life. High system pressure, resulting from high load, reduces expected life. System pressure must remain at, or below, rated pressure during normal operation to achieve expected life. Speed Maximum speed is the limit recommended by TurollaOCG for a particular gear pump when operating at rated pressure. It is the highest speed at which normal life can be expected. Speed versus pressure Rated The lower limit of operating speed is the minimum speed. It is the lowest speed at which normal life can be expected. The minimum speed increases as operating pressure increases. When operating under higher pressures, a higher minimum speed must be maintained, as illustrated to the right.

11 System Requirements Hydraulic fluids Ratings and data for SNP3NN and SEP3NN gear pumps are based on operating with premium hydraulic fluids containing oxidation, rust, and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion, and corrosion of internal components. They include: Hydraulic fluids following DIN 51524, part 2 (HLP) and part 3 (HVLP) specifications PI CD engine oils conforming to SE J183 M2C33F or G automatic transmission fluids Certain agricultural tractor fluids Use only clean fluid in the pump and hydraulic circuit. C Caution Never mix hydraulic fluids. Please see TurollaOCG publication Hydraulic Fluids and Lubricants Technical Information, L for more information. Temperature and Viscosity Temperature and viscosity requirements must be concurrently satisfied. Use petroleum / mineral-based fluids. High temperature limits apply at the inlet port to the pump. The pump should run at or below the maximum continuous temperature. The peak temperature is based on material properties. Don t exceed it. Cold oil, generally, doesn t affect the durability of pump components. It may affect the ability of oil to flow and transmit power. For this reason, keep the temperature at 16 C [6 F] above the pour point of the hydraulic fluid. Minimum (cold start) temperature relates to the physical properties of component materials. Minimum viscosity occurs only during brief occasions of maximum ambient temperature and severe duty cycle operation. You will encounter maximum viscosity only at cold start. During this condition, limit speeds until the system warms up. Size heat exchangers to keep the fluid within these limits. Test regularly to verify that these temperatures and viscosity limits aren t exceeded. For maximum unit efficiency and bearing life, keep the fluid viscosity in the recommended viscosity range. Fluid viscosity Maximum (cold start) 1 [46] mm 2 /s Recommended range 12-6 [66-29] [SUS] Minimum 1 [6] Temperature Minimum (cold start) -2 [-4] C Maximum continuous 8 [176] [ F] Peak (intermittent) 9 [194] L February 211 Rev B 11

12 System Requirements Filtration Filters Use a filter that conforms to Class 22/18/13 of ISO 446 (or better). It may be on the pump outlet (pressure filtration), inlet (suction filtration), or reservoir return (return-line filtration). Selecting a filter When selecting a filter, please consider: contaminant ingression rate (determined by factors such as the number of actuators used in the system) generation of contaminants in the system required fluid cleanliness desired maintenance interval filtration requirements of other system components Measure filter efficiency with a Beta ratio (β X ). For: suction filtration, with controlled reservoir ingression, use a β = 75 filter return or pressure filtration, use a pressure filtration with an efficiency of β 1 = 75. β x ratio is a measure of filter efficiency defined by ISO It is the ratio of the number of particles greater than a given diameter ( X in microns) upstream of the filter to the number of these particles downstream of the filter. Fluid cleanliness level and β x ratio Fluid cleanliness level (per ISO 446) Class 22/18/13 or better β x ratio (suction filtration) β = 75 and β 1 = 2 β x ratio (pressure or return filtration) β 1 = 75 Recommended inlet screen size µm [.4-.5 in] The filtration requirements for each system are unique. Evaluate filtration system capacity by monitoring and testing prototypes. 12 L February 211 Rev B

13 System Requirements Reservoir The reservoir provides clean fluid, dissipates heat, removes entrained air, and allows for fluid volume changes associated with fluid expansion and cylinder differential volumes. correctly sized reservoir accommodates maximum volume changes during all system operating modes. It promotes deaeration of the fluid as it passes through, and accommodates a fluid dwell-time between 6 and 18 seconds, allowing entrained air to escape. Minimum reservoir capacity depends on the volume required to cool and hold the oil from all retracted cylinders, allowing for expansion due to temperature changes. fluid volume of 1 to 3 times the pump output flow (per minute) is satisfactory. The minimum reservoir capacity is 125% of the fluid volume. Install the suction line above the bottom of the reservoir to take advantage of gravity separation and prevent large foreign particles from entering the line. Cover the line with a micron screen. The pump should be below the lowest expected fluid level. Put the return-line below the lowest expected fluid level to allow discharge into the reservoir for maximum dwell and efficient deaeration. baffle (or baffles) between the return and suction lines promotes deaeration and reduces fluid surges. Line sizing Choose pipe sizes that accommodate minimum fluid velocity to reduce system noise, pressure drops, and overheating. This maximizes system life and performance. Design inlet piping that maintains continuous pump inlet pressure above.8 bar absolute during normal operation. The line velocity should not exceed the values in this table: Maximum line velocity Inlet 2.5 [8.2] Outlet m/s [ft/sec] 5. [16.4] Return 3. [9.8] Most systems use hydraulic oil containing 1% dissolved air by volume. Under high inlet vacuum conditions the oil releases bubbles. They collapse when subjected to pressure, resulting in cavitation, causing adjacent metal surfaces to erode. Over-aeration is the result of air leaks on the inlet side of the pump, and flow-line restrictions. These include inadequate pipe sizes, sharp bends, or elbow fittings, causing a reduction of flow line cross sectional area. This problem will not occur if inlet vacuum and rated speed requirements are maintained, and reservoir size and location are adequate. L February 211 Rev B 13

14 System Requirements Pump drive Shaft options for Group 3 gear pumps include tapered, splined, or parallel shafts. They are suitable for a wide range of direct and indirect drive applications for radial and thrust loads. Plug-in drives, acceptable only with a splined shaft, can impose severe radial loads when the mating spline is rigidly supported. Increasing spline clearance does not alleviate this condition. Pilot cavity Mating spline Use plug-in drives if the concentricity between the mating spline and pilot diameter is within.1 mm [.4 in]. Lubricate the drive by flooding it with oil. 3-piece coupling minimizes radial or thrust shaft loads. Ø.1 [.4] P11 2E CCaution In order to avoid spline shaft damages it is recommended to use carburised and hardened steel couplings with 8-82 HR surface hardness. llowable radial shaft loads are a function of the load position, load orientation, and operating pressure of the hydraulic pump. ll external shaft loads have an effect on bearing life, and may affect pump performance. In applications where external shaft loads can t be avoided, minimize the impact on the pump by optimizing the orientation and magnitude of the load. Don t use splined shafts for belt or gear drive applications. spring-loaded belt tension-device is recommended for belt drive applications to avoid excessive tension. void thrust loads in either direction. Contact TurollaOCG if continuously applied external radial or thrust loads occur. 14 L February 211 Rev B

16 System Requirements Pump life Pump life is a function of speed, system pressure, and other system parameters (such as fluid quality and cleanliness). ll TurollaOCG gear pumps use hydrodynamic journal bearings that have an oil film maintained between the gear / shaft and bearing surfaces at all times. If the oil film is sufficiently sustained through proper system maintenance and operating within recommended limits, long life can be expected. B 1 life expectancy number is generally associated with rolling element bearings. It does not exist for hydrodynamic bearings. High pressure, resulting from high loads, impacts pump life. When submitting an application for review, provide machine duty cycle data that includes percentages of time at various loads and speeds. We strongly recommend a prototype testing program to verify operating parameters and their impact on life expectancy before finalizing any system design. 16 L February 211 Rev B

17 System Requirements Sound levels Fluid power systems are inherent generators of noise. s with many high power density devices, noise is an unwanted side affect. However, there are many techniques available to minimize noise from fluid power systems. To apply these methods effectively, it is necessary to understand how the noise is generated and how it reaches the listener. The noise energy can be transmitted away from its source as either fluid borne noise (pressure ripple) or as structure borne noise. Pressure ripple is the result of the number of pumping elements (gear teeth) delivering oil to the outlet and the pump s ability to gradually change the volume of each pumping element from low to high pressure. In addition, the pressure ripple is affected by the compressibility of the oil as each pumping element discharges into the outlet of the pump. Pressure pulsations will travel along the hydraulic lines at the speed of sound (about 14 m/s in oil) until affected by a change in the system such as an elbow fitting. Thus the pressure pulsation amplitude varies with overall line length and position. Structure borne noise may be transmitted wherever the pump casing is connected to the rest of the system. The manner in which one circuit component responds to excitation depends on its size, form, and manner in which it is mounted or supported. Because of this excitation, a system line may actually have a greater noise level than the pump. To reduce this excitation, use flexible hoses in place of steel plumbing. If steel plumbing must be used, clamping of lines is recommended. To minimize other structure borne noise, use flexible (rubber) mounts. The accompanying graph shows typical sound pressure levels for SNP3NN pumps (with SE flange, and spline shaft in plug in drive) measured in db () at 1 m [3.28 ft] from the unit in a semi-anechoic chamber. nechoic levels can be estimated by subtracting 3 db () from these values.
