Suction Strainer – A hydraulic power pack is the heart of many industrial machines, supplying pressurized fluid to drive cylinders, motors, and actuators. However, the efficiency of a power pack depends heavily on the cleanliness of its hydraulic fluid. One of the simplest yet most important components ensuring this cleanliness is the suction strainer.
At Unimarshal Technologies, we manufacture suction strainers designed specifically for hydraulic power packs, delivering durability, protection, and efficiency.
What is a Suction Strainer in a Hydraulic Power Pack?
A suction strainer is installed on the suction line of the hydraulic power pack pump. Its role is to:
- Prevent large contaminants like metal chips, dust, or debris from entering the pump.
- Protect the pump from cavitation and premature wear.
- Reduce load on downstream filters.
By capturing coarse particles at the entry point, suction strainers keep the entire hydraulic power pack running smoothly.
Why Are Suction Strainers Critical in Hydraulic Power Packs?
- Pump Protection – Prevents scoring, wear, and pump failure.
- Consistent Performance – Ensures uninterrupted hydraulic fluid flow.
- Lower Maintenance Costs – Extends the life of fine filters and pumps.
- System Reliability – Minimizes downtime in critical applications.
Applications of Suction Strainers in Hydraulic Power Packs
- Industrial Machinery – Press machines, injection molding, material handling systems.
- Construction Equipment – Hydraulic cranes, loaders, excavators powered by hydraulic packs.
- Automotive Industry – Test rigs, robotic arms, and precision hydraulic equipment.
- Mining & Drilling – Power packs used in rugged and dusty environments.
- Agriculture – Tractors, harvesters, and irrigation systems powered by hydraulic packs.
Technical Considerations for Choosing the Right Suction Strainer
When selecting a suction strainer for a hydraulic power pack, factors to consider include:
- Micron Rating: Typically 75–200 microns to avoid pump starvation.
- Flow Rate: Strainer area should be 3–4 times the pipe cross-section to prevent pressure drop.
- Material of Construction: Stainless Steel 304/316 for corrosion resistance, Duplex Steel for heavy-duty conditions.
- Mounting Style: Tank top strainers or inline suction strainers depending on the system design.
- Cleanability: Reusable mesh strainers allow easy maintenance.
Maintenance Best Practices
- Inspect suction strainers during regular hydraulic power pack servicing.
- Clean strainers to prevent clogging and pump cavitation.
- Replace damaged or worn-out strainers immediately.
- Always follow OEM recommendations for inspection intervals.
