Suction Filters

Suction Filters for Hydraulic Filtration

Protect hydraulic pumps and maintain cleaner hydraulic oil with Flowfit’s range of suction filters for hydraulic filtration. Designed for installation on the suction side of a hydraulic system, these filters help prevent larger particles and contaminants from reaching the pump while allowing the oil flow required for reliable system operation.

Our range includes hydraulic suction filters, suction strainers and tank side filters, providing filtration solutions for hydraulic reservoirs, power packs, mobile machinery and industrial equipment.

Correct suction-side filtration can help protect pumps from contamination, reduce unnecessary component wear and support the long-term reliability of your hydraulic system.

Hydraulic Suction Filters, Strainers & Tank Side Filters

Different hydraulic systems require different approaches to suction-side filtration. Flowfit’s range is organised into three main categories to help you find the most suitable solution.

Suction Filters
Hydraulic suction filters are installed between the reservoir and hydraulic pump to help remove contaminants from the oil before it enters the pump. They are suitable for applications where controlled suction-line filtration is required.

Suction Strainers
Hydraulic suction strainers provide coarse filtration at the pump inlet, helping prevent larger particles and debris from entering the hydraulic circuit. They are commonly fitted inside hydraulic reservoirs and provide a simple, effective first level of pump protection.

Tank Side Filters
Tank side hydraulic filters are designed for convenient installation on or around the hydraulic reservoir. Depending on the design, they can provide accessible filtration while helping simplify servicing and filter element replacement.

Why Suction Filtration Is Important

The hydraulic pump is one of the most critical components within a hydraulic system. Contaminated oil entering the pump can contribute to wear, reduced efficiency and premature component failure.

Using the correct hydraulic suction filter or strainer helps capture unwanted particles before they reach the pump and circulate through the rest of the hydraulic circuit.

Suction filtration must also be correctly sized for the required oil flow. Excessive restriction on the suction line can negatively affect pump performance, making flow capacity, filtration rating and connection size important considerations when selecting a filter.

Common Applications for Hydraulic Suction Filters

Suction filters, strainers and tank side filters are commonly used across:

• Hydraulic power packs and power units
• Hydraulic oil reservoirs and tanks
• Agricultural machinery
• Construction and plant equipment
• Mobile hydraulic systems
• Material handling equipment
• Industrial machinery
• Manufacturing equipment
• Hydraulic presses
• Machine tools
• Mobile plant and heavy equipment
• General hydraulic systems

They are particularly useful in hydraulic systems where protecting the pump inlet from larger contaminants is an important part of the overall filtration strategy.

Key Features of Suction Filters

Depending on the filter or strainer selected, key benefits can include:

• Filtration before hydraulic oil reaches the pump
• Helps protect hydraulic pumps from contamination
• Removal of larger particles and debris
• Suitable for suction-line and reservoir applications
• Options for different hydraulic flow requirements
• Range of connection sizes and configurations
• Suction strainers for in-tank installation
• Tank side filtration options
• Replaceable filter elements on selected designs
• Suitable for industrial, agricultural and mobile hydraulics
• Helps support cleaner and more reliable hydraulic systems

Choosing the Right Hydraulic Suction Filter

When selecting a hydraulic suction filter, it is important to consider the required flow rate, connection size, filtration rating, installation position and allowable pressure drop.

For reservoir-mounted applications, a hydraulic suction strainer may provide an effective solution for capturing larger contaminants at the pump inlet. Where convenient external access or reservoir mounting is required, a tank side filter may be more suitable.

Flowfit also supplies pressure filters, return line filters, hydraulic filter elements and other hydraulic filtration components, allowing you to build a complete filtration solution around your system requirements.
