Research & Development

GFS cares customers experience, has heavily invested in research and development department within the fields of hydraulic cylinder, oil and gas equipment (API 6A & 6D), high-speed rotary sealing solutions and etc since 2005.
 
In application, our goal is to minimize end-user care of  machinery  hydraulic system and let our customers focusing to get the job done.  To do this, We strictly  tested our products from the laboratory, we cooperated with  hydraulic machinery  manufacturers from design to production  and traced back the end-user using experiences for years.  Continually to improve our sealing products and provides detailed user guideline from R&D experiences to maximize the long-lasting & effective sealing goal.

    Among the sealing performance test levels of oil industry import devices, PR2 is the highest standard required by the American Petroleum Institute。
    Currently, domestic and foreign sealing manufacturers can only either pass the PR2 test of temperature level: PU, LU, PX, or pressure level: 5000,10000,15000 PSI. In October 2018, GFS sealing products passed the PR2 test of 3-1/16 valve, 15000PSI pressure level and KU temperature level equipped with Newell valve (Chinese gate valve Company). Only GFS passed the PR2 test among the 1 domestic and three foreign (S/C/T three international sealing solution giants) companies participating in the test.
    Note: in the above text, the letter P stands for the lowest temperature of -29℃, L stands for -46℃, K stands for -60℃, U stands for the highest temperature of 121℃, and X stands for 180℃
    The difficulties in passing the PR2 test are as follows:
    1. Great pressure change, 105MPa for high pressure and 5MPa for low pressure
    2. The test temperature changed greatly, from high temperature 121℃ to low temperature -60℃
    3. The sealing medium is nitrogen
    4. The sealing form is dynamic sealing
    5. Rigorous testing process: 160 presses at room temperature, 20 presses at high temperature, 20 presses at low temperature, 3 cycles of high and low temperature, 3 cycles of high and low pressure and high and low temperature

    Strategic Partner with Kenda, GFS is a Sealing leader of ceramic machinery industry
     KEDA Clean Energy is the world's largest ceramic machinery manufacturer  
    ceramics equipment suppliers, its main products - automatic ceramic pressure machine, cylinder diameter concentration between 800 mm to 1670 mm, because the system high pressure, high speed, large diameter, year-round work continuously (24 hours),  high requirement of the seals, the ceramic industry used import seals from foreign sealing giants   , but Kenda compressor oil leakage has been plagued by large-scale volume production.  since 2007, Kenda cooperated with GFS,  GFS targeted creative seal design, thoroughly to solve the problem of the product oil cylinder leaks, and It has reduced the cost of seals by more than 60 % and KENDA 80 % of its seals comes from GFS. which controls most of the industry's domestic market. It established GFS a leader in the ceramic machinery industry of Sealing. 
  • High-end PTFE material application in construction machinery market 
    More+
    At the past, in construction machinery, SB81 and above large diameter breaking hammer back end front 2 seals, excavator cylinder piston main seal are filled with PTFE modified products by imported brands, the most severe is the breaking hammer in mining industry. Since early 2015, GFS P4620 sealing material applied to the breaking hammer (maintenance) after market, started bulk supply the market in 2016. Supply to Yantai city, Anhui province and other places for the breaking hammer manufacturers. Now having more than 30% market share for breaking hammer, market feedback are cost-effective and durable. With application of P4620 sealing material, the costs of durable breaking hammer and excavator cylinder seals are largely dropped.
