The Future of Hydraulics is Electrifying
In recent years, the mobile hydraulics industry has been revolutionized by the development and proliferation of electric hydraulic systems. Among other inherent benefits, electric hydraulic systems could also be dramatically more energy efficient compared to traditional hydraulic systems.
How is this possible? Unlike traditional hydraulic systems, electric hydraulic motor-pump units only operate when flow and pressure are required to perform the working task at hand.
When there is no flow or pressure required, the electric hydraulic motor-pump unit switches to zero energy-mode, saving the consumption of energy and increasing the system’s efficiency. This is what we call energy efficiency.
Energy Efficiency through Electric Hydraulics
Energy efficiency, put simply, is when less energy is needed for a system to get the job done. This can be achieved by lowering the amount of energy consumed to accomplish an equivalent output (e.g. halt of use when not in operation).
Think about some of the newer car models in the market today.
Some higher-end models shut down every time the car stops at a stop light. Since the car is in idle at that stop light, why would the car continue to place tension and wear the performing components when they’re not performing their sole duty: driving?
This way of thinking is slowly creeping into hydraulics too. Experts are now looking at ways to incorporate these (and other) types of electric energy to power hydraulic machines. This is called electric hydraulics.
Electric Hydraulic Advantages
Electric hydraulic systems have some major advantages over their traditional hydraulic counterparts. The key advantages of electro-hydraulic motor pump units are:
- Up to 70% more efficient than standard hydraulic counterparts
- CO2 reduction = less fluid being used in the system
- Component lifespan increased, especially with bearings and seals
- Ability to control direction & amount of hydraulic flow by controlling direction/speed of the electric motor.
- Injection molding machine systems eliminate the need for directional and proportional valves in the motion axis.
- Fewer, less complicated components also simplifies troubleshooting.
- Quieter run times, reducing noise decibel readings
- Save space and reduce weight with lighter, more compact electric systems
- Integrated electrohydraulic packages are now available. These packages include an electric motor, controller, and hydraulic pump combined into one compact unit to lower total cost of ownership.
With the rising trend of electric drive vehicles and utilizing efficient energy throughputs, there is now a need to reduce power consumption and extend the battery life through increased hydraulic efficiency. How do we capitalize on saving energy and becoming more efficient in electric hydraulic systems?
The answer: minimize the pressure drop
Electric Drive Savings Through Pressure Drop Reduction
All energy has a price, and wasting it means wasting meaningful dollars. It is desirable to have as much energy that is inputted into a system available to do useful work. In hydraulic systems, we tend to look at differential pressure across the entire system. Differential Pressure describes the loss of energy available in a hydraulic system—however, the energy is not lost, but converted into thermal energy, which is unavailable to perform useful work.
For example, a small pressure drop effects high horsepower systems, as the pump/motor group must make up for that loss of energy and operate much harder, costing more money and shortening component life. Take a look at the figure below to see an example of how much money can be saved by lowering the pressure drop by a few psi:
So how do we lower the overall pressure drop in an electric hydraulic system? That is where Schroeder’s Electric Drive media can help.
Schroeder’s Electric Drive Media
The use of Schroeder’s GREEN, Electric Drive (E-Drive) Media filtration technology guarantees safe and reliable equipment operation, all-while conserving the use of energy.
Part of Schroeder’s Energy Saver initiative, filter elements made using the all-new E-Drive Media are characterized by a low pressure drop, making them suitable for low energy requirements compared to conventional hydraulic elements under the same ambient conditions.
In certain applications, the E-Drive Media can lower the pressure drop to a point where consumers may be able to size down their horsepower requirements on their current motor and save even more overall!
E-Drive filter elements are made using an all-new specialty formulated, high efficiency, low differential pressure media and are the perfect choice for use in electric hydraulic drive motor-pump units. Use them for conserving energy bills and wherever high viscosity fluids are employed – especially at low temperatures that produce a cold start behavior.

Fluid Contamination Control: What You Need to Know
Over 70% of all system failures are caused by contaminants in the fluid. Even when no immediate failures are apparent, high contamination levels can be present and sharply decrease hydraulic controls in the blink of an eye.
Contamination is defined as any substance foreign to the manufacturing equipment and damaging to its performance. If not controlled, contaminated hydraulic fluid can impact hydraulic system efficiency, reduce the lifespan of machine components, or even cause a catastrophic failure of hydraulic equipment, among other issues. Proper preventative measures, namely filtration, are critical.
There are four primary types of fluid contamination, each of which contribute to machine and component wear in their own ways. Each type of contamination can have a cascading effect which contributes to the other types.
Contamination can also act as a catalyst to accelerate oxidation of the fluid and spur the chemical breakdown of its constituents.

Trust the Experts of Process Filtration
Proper filtration in treatment processes such as process water, wastewater discharge, or reuse is critical.
Moving liquids or gases from somewhere like a refinery, food/beverage, steel, automotive, pulp and paper or oil produced water application requires pre-filtration due to high amounts of suspended solids in these typical applications.
In fact, there are usually several filtration and treatment steps in these applications to ensure that the treated water meets the required discharge or reuse standard.
In addition, filtration in treatment schemes ensures reduced operating cost on downstream polishing treatment systems.
Schroeder Industries Focuses on Your Process, Delivery Reliability and Improvements
Schroeder Industries will optimize your filtration solution based on the specific characteristics of your system, including the water source, specific application, and downstream equipment.
Poor filtration can cause a degradation of your final product or failure of downstream equipment. This can cost hundreds of thousands, or even millions of dollars in downtime or wasted product.
Schroeder Industries is here to partner with you to ensure reduced maintenance and high quality filtration designed specifically for your application.
The most important aspects of the application of filtration process include:
- System parameters
- Stable emulsions
- Water intake
- Economic impact
For instance, a very important step in a membrane treatment plant in the United States is the pretreatment of fluid to remove large particulate and biologicals.
If unmanaged, poor prefiltration can result in:
- Increased maintenance costs
- Increased energy consumption
- Damaged components (like a pump or heat exchanger)
- Reduced service times

What is a Fluid Filtration System?
A fluid filtration system is exactly what it sounds like. These systems are designed to ensure the quality of your fluid is excellent.
With a typical hydraulic application, the hydraulic filter is normally plumbed in-line with the system (or buried in-line with a hydraulic tank) and serves as an oil conditioning unit when the system is in operation.
A fluid filtration system, or oil conditioning unit, is a stand-alone unit that operates offline and away from the hydraulic application. Often times in the form of a hydraulic filter cart, it is not to replace any piece of equipment, but to enhance the maintenance team.
Equipped with a pump-motor group of its own, these do not require the power of a hydraulic machine. They are their own system.
Oil conditioning units are typically used for the conditioning of stored fluid, fluid dispensing applications and transferring processes. It is basically summed up that everywhere the fluid is not flowing through a system, it should be accompanied by a hydraulic filter cart.
What is meant by “Oil Conditioning”?
With the turn to tighter tolerances in today’s hydraulic critical assets systems, line conditioning equipment is critical.
What do we mean when we say “Oil Conditioning”?
Oil Conditioning is using fluid conditioning products, such as offline oil filtration and dehydration systems, to remove contaminates and increase the moisture removal rate in your hydraulic fluid. Removal of the contaminates and the total moisture allows the system to operate to its fullest potential. Contamination is a leading cause of hydraulic repairs and replacements, and accounts for 70 to 90% of wear and failure.
Whether your machine is new or many years old, the cleaner the oil, the better the operating condition.
When contaminants enter a hydraulic system, the manufacturer’s advertised performance of that machine is not achieved.
This adds an increased strain on components such as turbine oil filters, other line conditioning equipment, and more.
Today’s oil conditioning units have seen a shift from “Reactionary” (fix it when it breaks) to “Preventative” (fix it before it breaks), and even “Predictive” (schedule downtime to perform maintenance).
What are Diagnostics Tools?
Similar to a diagnostic OBD II scanner you have for your car, diagnostic tools are the equipment that can recognize and support a “Preventative” maintenance plan.
Bring that into the world of hydraulics and you get equipment similar to the OBD scanner mentioned above.
Only this time, these diagnostics read and report in the form of mineral oil cleanliness.
Watch on YouTube “Diagnostics (IoT)” Playlist.
When you pair the elite technology found in today’s oil conditioning units with the new-age of the Internet of Things (IoT) technology in most diagnostic tools on the market today, you really step into the future in a real effort of streamlining tedious oil sampling/reporting tasks in a complete system.
The two technologies together are what we like to call proactive “Contamination Control” – taking ownership and managing the fluids you pump into your hydraulic systems day-in and day-out.
“Contamination Control” pertains to the ISO clean analysis and optimization of processes with regard to the cleanliness of components, systems and the purity of the fluids used.
“Contamination Control” is also an important part of operating and maintaining hydraulic systems, like a hydraulic filter cart.
How can Schroeder Industries help?
It starts with the identification and measurement of the different forms of contamination.
Our line of condition monitoring products include both in-line and offline sensors to measure contamination and/or total moisture levels of the hydraulic system.
If the contamination levels are at a certain degree, our end users have seen dramatically frequent equipment failure.
If monitoring is the first step, fluid conditioning products would be the second.
Our line of offline, mobile fluid handling carts are perfect for removing contaminants and increasing overall moisture removal rate from various types of hydraulic fluids.
Oil conditioning units include both mobile fluid handling carts with or without contamination monitoring units, stationary fluid conditioning products from 1.3 gpm flow rates to customizable kidney loop systems up to 140 gpm.
Each of our hydraulic filtration systems are equipped with high efficiency elements to remove solid particulates and/or free water quickly and efficiently.
Our dewatering units, both hydraulic vacuum oil dehydration and mass transfer systems, can remove both free and dissolved water from hydraulic fluids for any reservoir size at various flow rates.
Watch on YouTube “Filter Systems” Playlist.
By implementing fluid condition monitoring equipment, in conjunction with the appropriate filtration equipment, a major portion of particulate contamination introduced during manufacturing and assembly can be effectively and efficiently removed.
The result will be improved fluid condition, extended life expectancy of fluid and equipment resulting in significant cost savings, and peace of mind that your systems are functioning appropriately and efficiently.

Filter elements are the heart and soul of every high pressure fluid power system. The main job of hydraulic filtration is to clean hydraulic fluid. This is achieved by removing impurities and contaminants in the system.
They are also used to ensure that contaminants do not interfere with the hydraulic machine’s main operating functionality. Such as maximizing efficiency and offering low energy consumption.
When a hydraulic oil filter removes those contaminants from a hydraulic system, an increase in the fluid’s cleanliness level is achieved. This results in the reduction of machine downtime and maintenance costs. A hydraulic oil filter also increases hydraulic fluid and component life, such as hydraulic pumps, hydraulic motors, etc..
Why Schroeder Filters?
At Schroeder Industries, our elements:
- Remove impurities and contaminants
- Meet required cleanliness levels
- Preserve energy on system components
- Maximize overall efficiency.
Schroeder Filter Media options that can help achieve your hydraulic fluid cleanliness and system efficiency goals. With numerous micron ratings and media options, there is a solution for you!
Use of Non-Schroeder Elements in Schroeder Filter Housings:
Due to the possibility of a fit, form, and function error, Schroeder Industries does not recommend nor
guarantee that a non-Schroeder filter element can be used properly in a standard Schroeder filter housing. Other businesses have filter elements that are not controlled by Schroeder, which may cause decreased performance and system downtime.
Potential Effects of Using Non-Schroeder Elements:
- Increased and Uncontrolled ISO Counts
- Lower Beta Efficiencies
- Uncontrolled Contamination Introduced in System
- Lower Dirt Holding Capacities
- Dissimilar Component Material from Original Specifications
- Material Issues Mixing with Hydraulic Fluid
- Premature System Component Failures
- Uncontrolled System Downtime
How can I tell if my hydraulic filter is working?
Genuinely, a filter element’s performance can be measured. Such factors to watch include:
- Beta Efficiency – how well it can remove contamination through fluid conditioning
- Beta Stability – how well it can maintain its efficiency throughout its life
- Dirt Holding Capacity (DHC) – how much contamination it can hold
- Lower Pressure Drop – how restricting it is on the hydraulic system
