6 System requirements / Requisiti del sistema Inlet pressure The inlet vacuum must be controlled within the prescribed range in order to achieve the expected pump life and performance. The system design must meet inlet pressure requirements during all modes of operation. is the highest intermittent pressure allowed. The reaction time of the pressure relief valve determines the duration of operation at pressure above the rated value. The maximum time interval is ms. The illustration to the right shows peak pressure in relation to rated pressure and reaction time ( ms maximum). Rated pressure is the average, regularly occurring, operating pressure that does not compromise the product's life and performance. System pressure is the pressure differential between the outlet and inlet ports. System pressure must remain at, or below, the rated pressure during normal operation to achieve expected life. Max. continuous vacuum.8 [23.6] bar abs. Max. intermittent vacuum.6 [7.7] [in. Hg] Max. pressure 3. [88.5] Time versus pressure Rated pressure Reaction time ( ms max) Time Hydraulic fluids Ratings and data for Continuum pumps are valid for operation 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 5524, part 2 (HLP) and part 3 (HVLP) specifications API CD engine oils conforming to SAE J83 M2C33F or G automatic transmission fluids Certain agricultural tractor fluids Use only clean fluid in the pump and hydraulic circuit. Never mix hydraulic fluids. COMER srl Via G. Rivani, Bologna Italy tel. 5/5337 fax. 5/6482

7 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 6 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) 3 [394] mm 2 /s Recommended range 32-5** [48-695] [SUS] Minimum 5 [23] Temperature Minimum (cold start) -5 [-4] C Maximum continuous 5* [22] [ F] Peak (intermittent) 9* [76] *For higher temperature than 5 C, please contact Settima. **For viscosity value out of this range, please contact Settima. Filtration Filters A Class 8/7/4 of ISO 446 (or better) filter must be used. 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 = 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 8/7/4 or better β x ratio (suction filtration) β = 75 and β = 2 β x ratio (pressure or return filtration) β = 75 Recommended inlet screen size -25 µm [.4-.5 in] The filtration requirements for each system are unique. Evaluate filtration system capacity by monitoring and testing prototypes. 8 COMER srl Via G. Rivani, Bologna Italy tel. 5/5337 fax. 5/6482

8 Reservoir The reservoir provides clean fluid, dissipates heat, removes entrained air and makes up for changes in fluid volume due to fluid expansion-contraction and flow imbalances associated with differential cylinders. A 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 8 seconds, allowing entrained air to escape. Hydraulic oil contains % of dissolved air by volume in normal conditions and the system should be design in order to avoid any over-areation of the hydraulic fluid, to limit any air release at the inlet port. 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. A fluid volume of to 3 times the pump output flow (per minute) is satisfactory. The minimum reservoir capacity is 25% of the fluid volume. The suction line shall be installed 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 -25 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. A baffle (or baffles) between the return and suction lines promotes deaeration and reduces fluid surges. COMER srl Via G. Rivani, Bologna Italy tel. 5/5337 fax. 5/6482 9

9 Pump drive Shaft options for Continuum pumps 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. Use plug-in drives if the concentricity between the mating spline and pilot diameter is within. mm [.4 in]. Lubricate the drive by flooding it with oil. A 3-piece coupling minimizes radial or thrust shaft loads. In order to avoid spline shaft damages it is recommended to use carburized and hardened steel couplings with 6-62 HRC surface hardness. Allowable radial shaft loads are a function of the load position, load orientation, and operating pressure of the hydraulic pump. All 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. A spring-loaded belt tension-device is recommended for belt drive applications to avoid excessive tension. Avoid thrust loads in either direction. Contact Settima if continuously applied external radial or thrust loads occur. Pump life Pump life is a function of speed, system pressure, and other system parameters (such as fluid quality and cleanliness). All Continuum 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 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. COMER srl Via G.

40 Tandem & multiple pumps / Pompe doppie e multiple Continuum pumps are suitable for multiple setups, whereby the drive shaft of the first pump is extended to a second and even a third Continuum pump. Each pump is connected to another by means of coupling. Each pump has its own suction port. Basically the technical specifications of single pumps apply also to multiple setups**. The maximum speed is determined by the highest pump speed rate in use. In case of multiple setup configurations, it is recommended to use the largest displacement for the first pump. The front pump may be equipped with different types of flange and shaft.
