Suction Strainers

Hydraulic Suction Strainers

Flowfit’s range of hydraulic suction strainers provides a simple and effective way to protect hydraulic pumps from larger particles, debris and contamination inside the reservoir.

Commonly installed directly within a hydraulic tank or reservoir, suction strainers sit at the pump inlet and act as an initial barrier against contaminants before hydraulic oil enters the suction line.

Their straightforward design makes them a popular choice for hydraulic power packs, mobile equipment, agricultural machinery and industrial hydraulic systems where reliable pump protection is required.

In-Tank Suction Strainers for Hydraulic Reservoirs

A hydraulic tank suction strainer is generally fitted inside the reservoir and connected to the suction port leading to the hydraulic pump.

Unlike finer filtration products used elsewhere in the circuit, strainers are primarily designed to capture larger contaminants while maintaining the high oil flow required at the pump inlet.

This makes them well suited to protecting pumps against debris that may enter the hydraulic tank during filling, maintenance or normal system operation.

Common Applications for Hydraulic Suction Strainers

Hydraulic suction strainers are commonly used in:

• Hydraulic tanks and reservoirs
• Hydraulic power packs
• Agricultural equipment
• Mobile machinery
• Construction and plant equipment
• Industrial hydraulic systems
• Material handling machinery
• Manufacturing equipment
• Hydraulic presses
• Compact hydraulic power units
• General mobile hydraulics
• Reservoir-fed pump systems

Key Features of Suction Strainers

Depending on the strainer selected, benefits can include:

• Helps prevent larger contaminants reaching the pump
• Designed for installation inside hydraulic reservoirs
• Suitable for hydraulic suction lines
• Helps protect pumps from debris
• Low-restriction filtration
• Straightforward installation
• Range of thread and connection sizes
• Options for different flow requirements
• Suitable for industrial and mobile hydraulic systems
• Effective first-stage contamination protection

Choosing the Correct Hydraulic Suction Strainer

When choosing a hydraulic suction strainer, consider the pump flow rate, thread size, filtration rating, physical dimensions and position within the reservoir.

The strainer should be sized to allow sufficient oil flow to the pump without creating unnecessary suction restriction. The location within the tank should also allow an adequate oil supply during operation.

For systems requiring finer or externally accessible filtration, Flowfit also supplies hydraulic suction filters and tank side filters, together with a complete range of hydraulic filtration components.
