Hydraulic Tank Accessories

Hydraulic tank accessories are essential components used to improve the functionality, safety, maintenance, and performance of hydraulic reservoirs. Properly selected tank accessories help control hydraulic fluid contamination, monitor oil level and temperature, support proper tank ventilation, and simplify filling, draining, and maintenance operations.

Hidroman provides a wide range of hydraulic reservoir accessories for mobile machinery, industrial equipment, agricultural machinery, construction equipment, mining applications, hydraulic power units, and OEM hydraulic systems.

Our engineering approach helps customers select the right tank components according to reservoir size, hydraulic fluid, operating conditions, filtration requirements, and machine design.

What Are Hydraulic Tank Accessories?

A hydraulic tank, also known as a hydraulic reservoir, is more than a container for hydraulic oil. It plays an important role in fluid storage, heat dissipation, air separation, contamination control, and overall hydraulic system performance.

Hydraulic tank accessories support these functions and may include components such as:

• Hydraulic tank breathers
• Oil level indicators
• Oil level gauges
• Temperature indicators
• Filler breathers
• Filler caps
• Hydraulic tank filters
• Suction strainers
• Return-line filters
• Drain plugs
• Magnetic drain plugs
• Tank inspection covers
• Clean-out covers
• Tank mounting accessories
• Seals and gaskets
• Oil filling components
• Hydraulic reservoir fittings

The correct combination depends on the hydraulic system design and operating conditions.

Hydraulic Reservoir Accessories from Hidroman

Hidroman offers hydraulic reservoir components designed for different hydraulic applications and tank configurations.

Rather than selecting individual components only by size, the complete hydraulic reservoir design should be considered, including fluid volume, filtration, temperature, contamination control, and maintenance requirements.

Hydraulic Tank Breathers

A hydraulic tank breather allows the reservoir to exchange air as the hydraulic fluid level changes.

The breather helps prevent excessive pressure or vacuum from developing inside the reservoir and can also reduce the amount of airborne contamination entering the hydraulic tank.

For demanding hydraulic systems, selecting the appropriate breather filtration level can be an important part of contamination control.

Oil Level Indicators

Hydraulic oil level indicators allow operators and maintenance personnel to visually check the fluid level inside the reservoir.

Maintaining the correct hydraulic oil level is important for proper pump operation, heat dissipation, and system reliability.

Depending on the tank design, level indicators may be available in different sizes, configurations, and mounting arrangements.

Oil Level and Temperature Indicators

Combined oil level and temperature indicators provide two important pieces of information from a single component.

Monitoring both oil level and temperature can help maintenance teams identify abnormal operating conditions before they develop into more serious hydraulic problems.

Hydraulic Tank Filler Breathers

A hydraulic filler breather combines the filling function with air filtration and is commonly installed on the top of a hydraulic reservoir.

A properly selected filler breather helps reduce contamination entering the reservoir during normal operation while providing a convenient point for adding hydraulic fluid.

Suction Strainers

Hydraulic suction strainers are installed in the suction circuit between the reservoir and hydraulic pump.

Their purpose is to prevent larger particles from entering sensitive hydraulic components.

Suction strainers must be correctly sized to avoid excessive restriction or cavitation risk at the pump inlet.

Hydraulic Return Filters

Return-line filters remove contamination from hydraulic fluid before it returns to the reservoir.

Proper return filtration is an important part of hydraulic contamination control and can help extend the service life of pumps, valves, cylinders, and other hydraulic components.

Drain Plugs and Magnetic Drain Plugs

Drain plugs provide a practical method for removing hydraulic fluid during maintenance.

Magnetic drain plugs can also help collect ferrous particles from the hydraulic reservoir, providing an additional indication of potential wear inside the hydraulic system.

Tank Inspection and Clean-Out Covers

Inspection covers provide access to the inside of a hydraulic reservoir for cleaning, inspection, and maintenance.

They are particularly useful for larger hydraulic tanks and industrial hydraulic systems where internal contamination must be controlled.

Why Are Hydraulic Tank Accessories Important?

Hydraulic oil contamination, incorrect oil levels, excessive temperature, and poor reservoir ventilation can negatively affect hydraulic system performance.

Proper tank accessories help support:

• Hydraulic fluid cleanliness
• Oil level monitoring
• Temperature monitoring
• Reservoir ventilation
• Contamination control
• Easier hydraulic oil filling
• Faster maintenance
• Reservoir inspection
• Hydraulic system reliability
• Longer component service life

A properly designed reservoir should therefore be considered an active part of the hydraulic system rather than simply an oil storage container.

Hydraulic Tank Accessories for OEM Applications

For OEM hydraulic systems, tank accessories should be selected during the hydraulic system design stage.

The reservoir and its accessories need to work correctly with:

• Hydraulic pumps
• Hydraulic motors
• Hydraulic cylinders
• Hydraulic valves
• Hydraulic filters
• Hydraulic coolers
• Hydraulic hoses
• Hydraulic power units
• Hydraulic manifolds
• Hydraulic control systems

For example, a high-flow hydraulic system may require different suction, return, and breather arrangements than a compact mobile hydraulic power unit.

Hidroman evaluates these requirements as part of the complete hydraulic system rather than treating the reservoir accessories as independent components.

Hydraulic Reservoir Accessories for Mobile Equipment

Mobile hydraulic equipment operates under demanding conditions including vibration, temperature changes, dust, shock loads, and frequent hydraulic cycle changes.

For this reason, hydraulic reservoir accessories used on mobile equipment should be selected according to the actual operating environment.

Typical applications include:

• Excavators
• Wheel loaders
• Agricultural machinery
• Tractors
• Forestry equipment
• Mining machinery
• Construction equipment
• Truck-mounted equipment
• Hydraulic lifting systems
• Mobile hydraulic power units

Compact and correctly specified tank components can help simplify installation while supporting reliable hydraulic system operation.

Hydraulic Tank Accessories for Industrial Hydraulic Systems

Industrial hydraulic systems often operate continuously and may require higher levels of contamination control and maintenance accessibility.

Hydraulic tank accessories can be used in:

• Hydraulic power units
• Press systems
• Steel production equipment
• Mining equipment
• Material handling machinery
• Manufacturing machinery
• Special-purpose machinery
• Automated hydraulic systems

For industrial applications, reservoir design should consider oil volume, heat dissipation, filtration, fluid cleanliness, maintenance access, and operating temperature.

How to Select Hydraulic Tank Accessories

Choosing the correct hydraulic reservoir accessories requires consideration of the complete hydraulic system.

1. Reservoir Capacity

Tank accessory dimensions and configurations should be compatible with the hydraulic reservoir.

2. Hydraulic Flow Rate

Suction strainers, return filters, and other flow-related components must be sized according to the actual hydraulic flow.

3. Operating Temperature

Temperature indicators, seals, breathers, and other components should be suitable for the expected operating temperature range.

4. Hydraulic Fluid

Materials and seals must be compatible with the hydraulic oil or fluid used in the system.

5. Contamination Level

The required filtration level should be determined according to the hydraulic components and cleanliness requirements of the system.

6. Installation Method

Thread type, mounting dimensions, port configuration, and available installation space should be checked before selecting the component.

7. Maintenance Requirements

If frequent inspection, filling, draining, or cleaning is required, tank accessories should be selected to make maintenance as practical as possible.

Hydraulic Tank Accessories and Contamination Control

Contamination is one of the most important factors affecting hydraulic component life.

Particles entering through the reservoir can circulate through pumps, valves, motors, and cylinders. Properly selected breathers, filling filters, suction strainers, and return filters can form an important part of the system's overall contamination-control strategy.

Hidroman also provides hydraulic filtration and fluid-conditioning solutions designed to support hydraulic system cleanliness and reliability.

For demanding systems, reservoir design, filtration, flushing, and oil cleanliness should be evaluated together.

Hydraulic Tank Accessories for Hydraulic Power Units

Hydraulic power units often require compact and carefully integrated reservoir components.

Depending on the HPU design, the tank may incorporate:

• Filler breather
• Oil level indicator
• Temperature indicator
• Suction connection
• Return connection
• Return filter
• Suction strainer
• Drain connection
• Inspection cover
• Magnetic components

Proper integration helps reduce installation complexity and makes maintenance easier.
