BLADDER ACCUMULATORS DETAILS
SFP Hydraulics’ bladder accumulators are pivotal components in hydraulic systems, storing energy under pressure and smoothly releasing it to ensure system efficiency. These accumulators come in several material choices and sizes, with operating temperatures tailored to a wide range of industrial applications. This ensures compatibility with various fluids and systems. Highly adaptable, they serve crucial roles in die-casting machinery, automotive suspension, emergency valve closing, and wind energy applications. They are distinguished by their superior shell construction of chrome molybdenum high-strength carbon steel and the optimized rubber compounds that constitute the bladder, offering enhanced physical properties and resistance to extreme temperatures and fluids. These accumulators provide improved system performance, contamination tolerance, and substantial lifespan while being light in weight and field-repairable.
Additional information
- Available in different bladder compounds, including Standard Nitrile, Ethylene Propylene, Butyl, and Fluoroelastomer, to suit a variety of operating environments.
- Operating temperature ranges from -61°F to +284°F, depending on the chosen bladder material.
- Designed according to rigorous international standards such as ASTM D-47, NF ISO 2782, and NF ISO 812.
- Features include excellent permeation resistance of Nitrogen gas and optimal compound mix for physical property enhancement.
- Suitable for high-pressure applications up to 10,000 PSI.
- The bladder accumulators are available in both bottom and top repairable designs for ease of maintenance.
- Tested and qualified for severe industrial applications, ensuring reliability in demanding conditions.
- Excellent shelf life with special compounds and sizes available for varied industrial needs.
- The detailed design and specifications of the bladder accumulators are provided, including the size, gas volume, dimensions, and weight, to assist in selecting the appropriate model for specific applications.

From our customers
I have been using SFP Hydraulics for my bladder accumulator needs for the last 7-8 years. In that time I have reached out to them on a number of items for which I have needed technical expertise for unique applications or commercial information, and without fail they have always come through and been able to get me on the right track. I rely on them for all of my bladder accumulator needs, and would recommend them highly to anyone.
Sean P. Carroll- Hydraulic Division Manager
I have been dealing with SFP since their formation in 2014. However, our relationship started well before that when the Core Group was with Oil Air. SFP’s products as well as their Product and Customer Service is always top notch. In the 10 years that I’ve been using SFP Products on a daily basis, SFP and their product lines have been a steadfast, reliable and resilient force in the Energy Sector. As I work in the Canadian Oilfield where temperatures range from +35 C (95 F) and above, to -40 C (-40 F) and below, resiliency is crucial. SFP is always up to the challenge.
