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.
