Is it possible that simply changing hydraulic fluids can result in a significant reduction in energy costs or an improvement in equipment output? The use of Maximum Efficiency Hydraulic Fluid (MEHF) offers an opportunity to reduce costs and improve hydraulic performance, but how much? How can MEHF impact a specific operation?

An educational Web site has been established that offers insight into the issue of hydraulic fluid efficiency, and offers a calculator which enables an operator to model any equipment fleet. At www.mehf.com, users can test the energy savings calculator located in the energy efficiency calculator and tools section (www.mehf.com/calculator).

The Maximum Efficiency Hydraulic Fluid Web site has been developed by RohMax Oil Additives Corporation, based on years of fluid development work in state-of-the-art hydraulic pumps. A variety of commercial fluids recommended by leading equipment manufacturers and major oil companies have been studied in gear, vane and piston pumps.

It is easy to conclude that fluid viscometrics (viscosity grade, viscosity index, and stability in high-pressure applications) are key in optimizing pump efficiency. Low pump efficiency results in higher energy costs (fuel or electricity), reduced power output and slower response time.

A fluid with high viscosity index meeting the defined MEHF performance level1 will outperform standard monograde (ASTM D6158 type HM) or engine oil-type fluids. The typical performance advantage in mobile equipment is in the range of 5 to 10 percent energy savings or productivity improvement.

Every type of hydraulic pump and motor is designed to have a small amount of internal fluid leakage or recycle. This fluid is essential because it forms a lubricating film between the moving parts which prevents wear.

If pumps and motors are operated at optimum temperature and pressure conditions, the amount of leakage is minimal and the pump can operate with greater than 90 percent efficiency. However, hard-working equipment is often placed under significant stress, resulting in high oil operating temperature.

As the temperature of the oil increases, the oil viscosity drops, and higher levels of internal leakage occur. It is not uncommon for mobile equipment hydraulic systems to produce sustained operating temperatures in the 80 to 100°C (176 to 212°F) range, with temperature spikes ranging between 110 to 130°C (230 to 266°F).

Oil temperatures greater than 60°C (140°F) decrease viscosities enough to have an appreciable negative impact on volumetric pump efficiency. It is common to find pumps operating at 50 to 60 percent volumetric efficiency when the oil temperature increases to 100°C (212°F). When a pump works at 60 percent efficiency, 40 percent of the input energy is wasted and converted into heat instead of work.

There are two elements of hydraulic efficiency: volumetric efficiency and hydromechanical efficiency. Hydromechanical efficiency relates to the frictional losses within a hydraulic component and the amount of energy required to generate fluid flow. Volumetric efficiency relates to the flow losses within a hydraulic component and the degree to which internal leakage occurs. Both of these properties are highly dependent on viscosity.

Hydromechanical efficiency drops as fluid viscosity increases due to higher resistance to flow. Conversely, volumetric efficiency increases as fluid viscosity increases because of the reduction of the internal leakage. The overall efficiency of a hydraulic pump is the product of mechanical and volumetric efficiencies [Equation 1], and both factors must be considered collectively.4

Loss of volumetric efficiency causes the pump to work harder and/or longer to produce the required flow to hydraulic actuators. At the same time, high temperatures compromise volumetric efficiency as the result of low-viscosity fluid bypassing critical pump clearances. Thus, inadequate viscosity due to high temperatures creates a destructive cycle of rising temperatures, accelerated wear and increased internal leakage.

All pump manufacturers publish the maximum and minimum oil viscosity requirements for their pumps. A summary of these recommendations can be found in the National Fluid Power Association recommended practice NFPA-T2.13.13-2002, or on the MEHF Web site.6 Please consult the pump or equipment manufacturer directly for specific guidance on fluid viscosity requirements.

Maximum Efficiency Hydraulic Fluids are designed to provide increased viscosity at standard and peak operating conditions. The result is an improved ability to meet the OEM viscosity requirements over a wider range of temperature and pressure conditions, thus maintaining higher pump efficiency.

Extensive testing has demonstrated that high-viscosity index fluids provide better pump efficiency at operating conditions.(7,8,9) However, these high-performance fluids cost more than standard monograde fluids or engine oils, so what is the net benefit?

While nearly any hydraulic application can take advantage of MEHF performance, heavy-duty equipment operating at higher temperatures (greater than 60°C/ 140°F) and pressures (2,000 psi/ 138 bar) are the most significant benefit. Most mobile construction, forestry, agriculture and stationary outdoor equipment fall into this category.

In general, five to ten percent energy savings or productivity improvement may be achieved, which can mean savings of hundreds of dollars per pump every year.10 Because each system may have unique design and/or operating conditions, it is necessary to account for the differences in estimating potential benefits.

It is possible to model a simple system with one hydraulic pump (for example, a wheel loader), or a complex piece of equipment with multiple pumps and rotary motors (for example, a heavy-duty excavator). One can also model a small or large fleet if there is an accurate count and differentiation between the different types of pumps (gear, vane, and piston)and motors in service (Figure 1).

The referenced calculator will compute the total energy input requirement necessary to run the hydraulic systems only. It does not consider energy used to move the equipment with a standard transmission or other auxiliary equipment (air conditioning, electrical systems, etc.).

The user must input the total number of gear, vane, piston pumps and motors in service, the typical number of hours per day and days per year that they operate at full load. The calculator assumes that each pump is medium sized, and operates at typical temperature and pressure conditions.

The use of a single average operating condition assumes that actual conditions are milder for 20 percent of the time and more severe for 20 percent of the time. Typical fluid operating temperatures were derived from a year-long observation of forestry and construction equipment(3), as well as from guidance received from multiple pump and equipment OEMs.

The model assumes that the gear pump operates at 207 bar (~3,000 psi), the vane pump operates at 200 bar (~2,900 psi), and the piston pump operates at 350 bar (~5,000 psi), when at full load.

Total oil consumption is based on the assumption that the volume of the sump is 1.5 times the flow rate of the pump with the fluid changed annually. Every piece of equipment has a different rate of oil loss (through line/coupling leakage, hose breaks or evaporation), and therefore the calculator asks for an estimate of the annual top-up rate.

The calculator assumes that the pipes and hoses are standard diameter and that the total length of piping does not lead to a significant difference in hydromechanical efficiency between the fluids being compared.

Viscosity grade is a critical factor in determining the difference in overall pump efficiency. The user is asked to input the current type of fluid in use and its cost per gallon or liter.

The possible fluid options include the typical ISO viscosity grades (22, 32, 46 and 68) in monograde (type HM) and multigrade (type HV), as well as the widely recommended options of 10W engine oil and ATF. The same fluid may be selected for all-season use, or different fluids can be used for winter/summer rotation.

The viscosity/temperature profile of each fluid determines the actual pump flow rate at operating pressure. The actual flow rate of each pump as a function of oil temperature, viscosity and operating pressure is known.

Data for pump flow rates as a function of temperature, pressure and viscosity were taken from the pump suppliers’ product literature, and have been verified with test data measured in previous studies.(6,7,8) Internal pump leakage at the operating pressure determines how much the actual flow rate (Qa) varies from the nominal (Qn) flow rate.

Pump efficiency is the ratio of actual flowrate to nominal flow rate. The pump requires a constant amount of input energy to turn at a constant speed. The pump efficiency determines how much of the input energy is converted into fluid flow and useable work. All input energy that is not converted into pump output is transformed into heat.

This energy is absorbed by the fluid trapped in the pump and causes the temperature of the fluid to increase, which also leads to further reduction in viscosity. The calculator compares the actual flowrate and input power requirements of the pump using the fluid options selected by the user. It is possible to calculate the difference in energy consumption required to do the same amount of work according to the following formula:

Based on the pumps selected and total annual hours of operation, the calculator can determine the total number of kilowatt hours required to run the hydraulic system with the current reference fluid. The ratio from the equation above determines how much energy can be conserved to perform the same amount of work with the MEHF.

The decision to change oil seasonally will have a significant impact on maintenance costs. The user is asked to estimate the time and labor costs for an oil change and indicate if hydraulic system downtime leads to a cost for lost production. In some operations like forestry or mining, machinery that is out of service for maintenance will cause a reduction in output or productivity that costs the company money. The calculator can add in these factors if it is relevant to the operation.

The final step in the comparison process is the selection of an MEHF. A Maximum Efficiency Hydraulic Fluid is characterized by high viscosity index (>150) and good shear stability. The user can select an MEHF candidate with an ISO viscosity grade of 22, 32, 46 or 68 and a viscosity index of 160, 180 or 200.

Many controlled studies have concluded that hydraulic fluid viscometrics are the key to achieving good pump efficiency. Choosing a fluid with high viscosity index and good shear stability will enable hard-working systems to minimize fuel or electricity consumption and improve productivity. This performance advantage can typically afford the operator a five to ten percent reduction in operating costs.

A simple-to-use energy savings calculator is now available at www.mehf.com/calculator, which enables the equipment owner or operator to model his specific piece of equipment or entire operation. Basic information about pump types, hours of operation and fluid selection allows the calculator to estimate total energy demand.

For instance, differences in engine maintenance will influence nascent efficiency, which may appreciably influence the accuracy of the final estimate. This must be considered, as well as the tool used to guide the decision-making process.

The MEHF performance level definition, extensive pump operation data and MEHF Web site have been developed by RohMax Oil Additives as a service to the lubricants industry.

Hydraulic pumps come in different forms to accommodate a range of application requirements, from industrial die presses to heavy-duty off road equipment. One hydraulic system can vary greatly from another. For one system, a hydraulic piston pump may be the best solution, while a hydraulic gear pump may be better suited for a different one.

Powered by a hydraulic drive, a piston pump has a reciprocating positive displacement design to manage fluid flow. Pistons, or cylindrical elements within a cylinder block, create a vacuum, generated by a drive mechanism, that draws in fluid. The cylindrical chamber is pressurised by distributing energy into the fluid, compressing and forcing it towards the pump’s outlet.

Basic designs can generate about 4,000 psi, but pumps with up to 14,500 psi operating pressure are available. There are many different models that can displace a specific amount of fluid. Some allow you to adjust the displacement per revolution, which can make them more energy efficient. Piston pumps are relatively complex in design and expensive, but practical in energy-efficient applications that require high pressures and effective oil flow control.

A hydraulic gear pump is a lower-cost option, but it is quite durable, with many options available. The typical pressure rating is about 3,000 psi, but many displacement sizes and pressures can be found. Some gear pumps are rated as high as 4,500 psi, although additional valves will be needed in systems that require regular flow adjustments.

Gear pumps function by drawing fluid between their meshing gears. The adjacent gear teeth form chambers that are enclosed within the housing and pressure plates. A partial vacuum forms at the inlet where the gear teeth unmesh, allowing fluid to fill the space and be moved along the outer edge of the gears; as the gear teeth mesh again, fluid is forced out of the pump.

Both pumps use hydraulic fluid to transfer energy or generate mechanical force. Hydraulic piston pumps rely on reciprocating motion. Rotational forces are generated along an axis. Fixed and variable displacement pumps are available, as are different types, including axial, inline, bent-axis, plunger, and radial pumps, each with its own unique method of pushing fluid.

On the other hand, gear pumps move fluid via tightly aligned cogs that create suction to draw in and discharge fluid. Pumps with internal or external gears can be used, depending on the application requirements. Lobe, screw, and vane pumps are just some available types. A downside of using gear pumps is that additional devices are needed to control the desired amount of displacement, as they operate on fixed displacement only.

While gear pumps are available in a wide range of displacement sizes and pressures, and they suit various machinery applications, piston pumps offer the benefits of higher pressure ratings and are variable displacement and energy efficient. Rapid cooling means each pump is ready for the next operating cycle and can be serviced soon after shut-off.

Gear pumps typically don’t move more than 50 gallons per minute of fluid. On the other hand, some piston pumps can move hundreds of gallons per minute. Either one has advantages, depending on your hydraulic application.

Hydraulic pumps are available in different types, sizes, pressure ratings, and other specifications. It is important to choose the right pump for your hydraulic system. Gear pumps are suited for various types of machinery. Piston pumps are often found in oil field and agricultural applications, as well as in heavy-duty construction equipment. They are reliable and efficient, and they resist leakage at high speeds and pressures.

If you’re a pump sprayer operator and you’re performing a soft wash application on a two-story residential home to remove lichen or mold, how do you get the spray pattern to reach the eaves of the home and provide even coverage without having to climb a ladder?

There’s a common misconception that to achieve a broader vertical or horizontal spray pattern, you simply need a pump that puts out more pressure. On the contrary, increasing the flow rate is often the key.

It’s not uncommon to hear pump operators complain that their sprayer doesn’t have enough pressure when, in fact, the issue is the flow rate. In fact, some people use the two terms interchangeably, as though they’re the same thing. They’re not, and knowing the difference and the role each plays is the key to achieving proper pump performance.

A pump’s job is not to deliver pressure; rather, it is to deliver a rate of flow, pumping a certain amount of liquid over a given amount of time from a tank or reservoir to the outlet. Flow rates are often referred to in gallons per minute or GPM. There are some smaller pumps that rate flow at gallons per hour or even gallons per day, outputting extremely small amounts of fluid over a given time.

Pump pressure, however, is a measure of resistance to flow. Without flow, there is no pressure. In a positive displacement pump, such as a plunger pump, the rating in pounds per square inch, or PSI, outlines how much resistance the pump is designed to withstand.

A pump’s PSI rating is important because it indicates that the pump was manufactured out of materials and designed to handle a certain amount of pressure. But for pump operators, they should be equally concerned with a pump’s flow rate which determines how much you want to dispense, spray, or inject.

In general, when pump pressure increases, flow will decrease. Take, for example, a misting pump that needs to produce an ultra-fine mist for cooling or dust suppression. Many misting pumps are rated at 1,000 PSI, yet their flow rate is quite low at .25 GPM.

More pressure changes the velocity of the fluid, but it also decreases the flow or output. The cause of the flow decrease is due to two factors: volumetric efficiency of the pump and reduced motor speed. Volumetric efficiency is a measure of the actual flow compared to expected theoretical (calculated) flow — volumetric efficiency decreases as pressure increases. Our positive displacement plunger pumps have about 90–100% volumetric efficiency compared to centrifugal pumps that range from 0–100%. This means that plunger pumps only lose about 10% of the flow when pumping against back-pressure, while centrifugal pumps will lose all the flow when pressure climbs too high.

Reduced motor speed occurs when motors are loaded heavier. So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating.

It stands to reason, then, that increasing pump pressure will not increase flow. In the soft wash example, more pressure won’t help the operator reach the eaves of a two-story home with the same amount of coverage. The operator needs a pump motor with an ideal combination of pressure and flow.

Engineering pumps for any application requires an understanding of fluid dynamics, and each industry has varying needs. Too often, a company will choose an off-the-shelf high-pressure pump to get a job done and wonder why it doesn’t perform as expected. It’s likely because the operators lack a full understanding of the relationship between flow and pressure.

The engineering experts at Pumptec have a thorough grasp on fluid dynamics and help OEMs and pump distributors pinpoint their exact needs. They make recommendations based on scientific principles and years of experience serving multiple industries, and can even customize pumps to your application’s precise needs.

In fact, we’ve developed a Guide to GPM and PSI that provides some of those industry recommendations. Take a look through it and then contact the pump experts at Pumptec. We’ll be happy to discuss your needs and determine the right pump for your application.

Despite recent advances in predictive maintenance technologies, the maintenance professional’s ability to determine the remaining bearing life of a pump or motor, with a high degree of accuracy, remains elusive.

Deteriorating efficiency on the other hand is easy to detect. Because it typically shows itself through increased cycle times. In other words, the machine slows down. When this occurs, quantification of the efficiency loss is not always necessary. Reason being, if the machine slows to the point where its cycle time in unacceptably slow, the pump or motor is changed out. End of story.

In certain situations however, it can be helpful, even necessary, to quantify the pump or motor’s actual efficiency and compare it to the component’s native efficiency. And for this, an understanding of hydraulic pump and motor efficiency ratings is essential.

There are three categories of efficiency used to describe hydraulic pumps (and motors). Volumetric efficiency, mechanical/hydraulic efficiency and overall efficiency.

Volumetric efficiency is determined by dividing the actual flow delivered by a pump at a given pressure by its theoretical flow. Theoretical flow is calculated by multiplying the pump’s displacement per revolution by its driven speed. So if the pump has a displacement of 100 cc/rev and is being driven at 1000 RPM its theoretical flow is 100 liters/minute.

Actual flow has to be measured using a flow meter. If when tested, the above pump had an actual flow of 90 liters/minute at 207 bar (3000 PSI), we can say the pump has a volumetric efficiency of 90% at 207 bar (90 / 100 x 100 = 90%).

It’s volumetric efficiency we use most in the field to determine the condition of a hydraulic pump – based on its increase in internal leakage through wear or damage. But without reference to theoretical flow, the actual flow measured by the flow meter would be meaningless.

A pump’s mechanical/hydraulic efficiency is determined by dividing the theoretical torque required to drive it by the actual torque required to drive it. A mechanical/hydraulic efficiency of 100% would mean if the pump was delivering flow at zero pressure, no force or torque would be required to drive it. Intuitively, we know this is not possible – due to mechanical and fluid friction.

Like theoretical flow, theoretical drive torque can be calculated. For the above pump, in SI units: 100 cc/rev x 207 bar / 20 x pi = 329 Newton meters. But like actual flow, actual drive torque must be measured and this requires the use of a dynamometer. Not something we can-or need-to do in the field. For the purposes of this example though, let’s assume the actual drive torque was 360 Nm. Mechanical/hydraulic efficiency would be 91% (329 / 360 x 100 = 91%).

Overall efficiency is simply the product of volumetric and mechanical/hydraulic efficiency. So continuing with the above example, the overall efficiency of the pump is 0.9 x 0.91 x 100 = 82%. Typical overall efficiencies for different types of hydraulic pumps are shown in the table below (source: Bosch Rexroth):

Overall efficiency is used to calculate the drive power required by a pump at a given flow and pressure. For example, using the overall efficiencies from the table above, let us calculate, in SI units, the required drive power for an external gear pump and a bent axis piston pump at a flow of 90 liters/minute at 207 bar:

As you’d expect, the more efficient pump requires less drive power for the same output flow and pressure. With a little more math, we can quickly calculate the heat load of each pump:

No surprise then, that a system with gear pumps and motors requires a bigger heat exchanger (all other things equal) than an equivalent system with piston pumps and motors.
