4 4 shhark GROUP 2 I TECHNICL INFORMTION shhark Low Noise technology The standard technology currently used in low noise gear pumps is based on double-flank contact. This solution reduces the peak-to-peak flow pulsation by 75% compared to a single-flank contact gear pump with the same number of teeth. Turolla shhark aims to the same reduction of flow pulsation, but in a totally different way. s illustrated below, for the same outer diameter, shhark gear features almost twice as many teeth of a standard pump gear, thanks to a revolutionary design of asymmetric tooth profile. Moreover, the shhark teeth are also slightly helical; the small helix angle does not generate any additional axial load but makes the flow characteristic smoother, further reducing the flow pulsation. Standard Gear Pump (11T) Turolla shhark standard gears vs shhark The comparison between the flow characteristic of Turolla SKP2 (11-teeth) and shhark (19-teeth) is illustrated in the plot below: the reduction of peak-to-peak flow pulsation is 78%. In addition, the average flow per unit width of shhark is approximately 2.7% higher than SKP2; this means that for the exact same pump s dimensions, shhark delivers more flow. Flow characteristics of Turolla shhark vs SKP2

5 shhark GROUP 2 I TECHNICL INFORMTION 5 dvantage of shhark vs the double-flank contact technology The effectiveness of double-flank contact is very likely to decrease throughout the pump s life, because external gear units often work at high pressure with high level of contaminants in the hydraulic fluid. In such conditions the critical components of the rotating kit slowly wear out, with a progressive loss of the double-flank contact condition and with it, the low noise performance. shhark does not rely on any short-lived condition as double-flank contact, because the reduction of flow pulsation is achieved through the increased number of teeth. The clearances associated with the meshing of shhark gears are of the same order of magnitude of standard gear pumps. Therefore the noise performance of shhark remains constant throughout the pump s life. Pump design In terms of rated operating range (speed, pressure and temperature), overall dimensions and available configurations shhark has been design to be essentially a low noise version of SKP2. The 2 mm shaft can accommodate any type of drive end, such as S(SE 9T-16/32), SB(SE 11T-16/32), (Taper 1:5), B(Taper 1:8), G(Parallel SE Ø15.875), C(Tang 8x17.8). s for SKP2, the hydrostatic compensation system is on the bearing blocks, to ensure high efficiency and also more compact tandem combinations and higher flexibility to distribution.

17 shhark GROUP 2 I TECHNICL INFORMTION 17 System requirements Inlet pressure Inlet vacuum must be controlled in order to preserve expected pump's life and performance. The system design must meet inlet pressure requirements during all operation modes. Expected lower inlet pressures during cold start will be improved as soon as the fluid warms. Inlet pressure Max. continuous vacuum bar abs..7 [2.7] Max. pressure [in. Hg] 4. [118.1] Time versus pressure Peak pressure is the highest intermittent pressure allowed at the pump's outlet. Peak pressure depens on the relif valve over shoot (reaction time). The illustration to the right shows peak pressure in relation to rated pressure and reaction time (1 ms maximum). Pressure Peak pressure Rated pressure Rated pressure is the max continous operating pressure. The maximum machine load demand determines rated pressure. Reaction time (1 ms max) Time Speed Maximum speed is the limit recommended by Turolla 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 P 2 Rated pressure 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. Pressure P 1 Operating Envelope N 1 N 2 N 3 Speed Where: Max Where: N 1 = Minimum speed at 1 bar N 2 = Minimum speed at 18 bar N 3 = Minimum speed at rated pressure

18 18 shhark GROUP 2 I TECHNICL INFORMTION Hydraulic fluids Ratings and data for shhark are guaranteed when the hydraulic pump works with premium hydraulic fluids containing oxidation, rust, and foam inhibitors. These fluids have to work with 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 Please see Turolla publication Hydraulic Fluids and Lubricants Technical Information, L for more information. Caution Never mix hydraulic fluids. Temperature and viscosity Temperature and viscosity requirements must be concurrently satisfied. Use petroleum / mineralbased fluids. High temperature limit apply at the inlet port of 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 viscosity It occurs only during brief occasions of maximum ambient temperature and severe duty cycle operation. Maximum viscosity It occurs 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]

19 shhark GROUP 2 I TECHNICL INFORMTION 19 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). Recommendations and remarks 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. βx 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 βx 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.

20 2 shhark GROUP 2 I TECHNICL INFORMTION Reservoir The reservoir provides clean fluid, dissipates heat, removes entrained air, and allows 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 de-aeration 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 line 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 speed 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 inlet vacuum conditions the oil releases the dissolved air. Moreover, when inlet vacuum is particularly severe, the hydraulic fluid may cavitate, 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.

21 shhark GROUP 2 I TECHNICL INFORMTION 21 Pump drive Shaft options for shhark Group 2 gear pump include tapered, tang, 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] Caution In order to avoid spline shaft damages it is recommended to use carburized 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. Use a tapered input shaft; 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 Turolla if continuously applied external radial or thrust loads occur.

23 shhark GROUP 2 I TECHNICL INFORMTION 23 Pump life Pump life is a function of speed, system pressure, and other system parameters (such as fluid quality and cleanliness). ll Turolla 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. Sound levels Fluid power systems are inherent generators of noise. s with many high power density devices, noise is an unwanted side effect. However, there are many techniques available to minimize noise associated with 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 high to low 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 response of one circuit component 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 SHHP2NN and SKP2NN pumps (with SE flange and spline shaft) expressed in db() at 1 m [3.28 ft] from the unit. Data were taken using ISO VG46 petroleum /mineral based fluid at 5 C (viscosity at 28 mm2/s [cst]). Contact your Turolla representative for assistance with system noise control.

Contact your Turolla representative for availability. Caution Shaft torque capability may limit allowable pressure. Torque ratings assume no external radial loading. pplied torque must not exceed these limits, regardless of stated pressure parameters. Maximum torque ratings are based on shaft torsional fatigue strength. The second section torque limit is equal to 7Nm. Other configuration with higher rated torque are available upon request.

30 3 shhark GROUP 2 I TECHNICL INFORMTION Pumps with integral relief valve SHHP2EN and SHHP2IN Group 2 pumps are offered with an optional integral relief valve in the rear cover. This valve can have an internal (SHHP2IN) or external (SHHP2EN) drain. This valve opens directing all flow from the pump outlet to the internal or external drain when the pressure at the outlet reaches the valve setting. This valve can be ordered preset to the pressures shown in the table below. Valve performance curve, rear cover cross-section and schematics are shown below. Please contact Turolla Engineering Department for further information Caution When the relief valve is operating in bypass condition, rapid heat generation occurs. If this bypass condition continues, the pump prematurely fails. The reason for this is that it is a rule, not an exception. When frequent operation is required, external drain option (SHHP2EN) must be used.
