Use our online accumulator volume sizing calculator to determine optimal capacity.
Open Volume Calculator →The SCHWERLL standard bladder accumulator series uses high-grade synthetic elastomer compounds and a special process to produce bladders with low permeability, high fatigue life, wide-range thermal endurance (-40°C to +120°C), and special material adaptability for special media.
Contact Schwerll engineering sales directly for custom volume sizing, pressure ratings (up to 207 MPa), and volume pricing.
The SCHWERLL standard bladder accumulator full series adopts high-grade synthetic elastomer compounds and is made with a special process. The bladder has low permeability, high fatigue life, wide-range thermal endurance (-40°C to +120°C), and special material adaptability for special media.
BAK series: Suitable for most working conditions, G2″ oil-side mushroom valve, maximum working flow rate 15 l/s, volume range up to 57L, maximum pressure 350bar;
BAKM series: Increased liquid-side outlet flow rate series, G2″ oil-side mushroom valve, maximum working flow rate 25 Vs, volume range up to 250L, maximum pressure up to 400bar
BAKH series: Increased liquid-side outlet size series, increased outlet flow rate, volume range up to 350L (high pressure), 570L (low pressure) pressure up to 350bar
1. System oil discharge under specified working pressure difference ΔV=V2-V1 @ P2 drop to P1
2. Bladder accumulator P2:P0≤4:1
3. PO@Tmax≤0.9*P1 (PO value see sample description, according to working conditions)
4. Liquid medium related factors: metal part corrosion and rubber base adaptability
5. Determination of selection pressure: Under normal working conditions, design pressure ≥1.1 times the maximum system working pressure
6. Bladder pressing and bonding molding, forming a plum blossom shape compression
7. Confirm that the product meets the standards required by the local government
8. Inflation valves and oil valves are all SCHWERLL company’s own products, ensuring quality
