Compressors/Blowers

Bladder Type Accumulator

These standard bladder accumulators are manufactured based on years of experience and proven performance. Bladders are replaceable and available in various sizes up to large-volume ones. Their extensive applications include general industrial machineries, construction machineries, power plants and chemical plants.

NF941

Single seal with double seal function Non-contacting from static to high speed condition Balanced Independent of direction of rotation Stationary multiple springs

DGS

Wear and contact free operation Self cleaning 3-D gas grooves High gas film stiffness Safe cupped retainer for rotating ring Available in various materials for optimized chemical resistance Proven, reliable and economical solution

PDGS

High quality components make this a universal seal for a wide range of applications and the ideal solution for standardization. The universal gas seal for centrifugal compressors; resistant to chemicals.

MDGS

The rotating ductile ring with a high　performance coating is the main distinctive feature to other dry gas seals. It offers outstanding wear resistance in low speed conditions e.g. coast down or turning where contacting of seal faces is inevitable. The required radial space of this seal is smaller than existing Dry Gas Seals and the seal fi ts into small seal cavities, as you fi nd them in process gas screw compressors, without making any compromise with regard to seal reliability. The stationary spring loaded unit is supplied as a sub cartridge in combination with a rotating ductile seat integrating secondary functions such as centring and secondary sealing by means of an O-Ring allow the use of this seal as a component seal.

NF953

Gas-lubricated Independent of direction of rotation Single, double, tandem, tandem with intermediate labyrinth available

LEK777

Mechanical Seals for Pumps Pusher Seals Suitable for higher speeds Good followability due to no influence from run-out, squareness or vibration of the shaft Compact design Low heat generation and power consumption due to narrow seal face width Longer seal life Pressure-balanced design prevents mating ring being forced out under reverse pressure No damage to shaft sleeve as dynamic O-Ring is not in direct contact with the sleeve

QS300

Three-segmented seal The segmented structure ensures superb followability in the radial direction. The floating structure achieves superb durability, eliminating the need for cooling. Precision machining minimizes leakage to levels comparable to those of contact type segment seals. Compared with conventional segment seals, this seal consists of a smaller number of parts and is therefore robust. The shaft is hardly subject to wear, and does not require hardening treatment. The unit structure allows easy installation and handling. A cartridge structure including a sleeve is also available. Flammable gas and toxic gas can be completely sealed by using two sets of QS300 in a double seal arrangement (QS310) and a buffer gas.

分割構造で、径方向への追随性に優れています。フローティング構造により、優れた耐久性を発揮し、冷却が不要です。精密加工をすることにより、接触式セグメントシールに匹敵する低漏洩を実現しました。 従来のセグメントシールと比較して部品点数が少なく堅牢で、軸の摩耗が殆どなく軸の硬化処理も不要です。 ユニット構造のため取付け・取扱いが簡単で、スリーブを含めたカｰトリッジ構造も可能です。 また、ダブルシールQS310としてバッファガスを併用すれば、可燃性ガスや有毒ガスを完全にシールできます。

EA111

Rotating-shaft seal designed exclusively for refrigerator compressors Helps eliminate CFC leakage causing global warming Sliding materials made of special cast iron and carbon components suitable for CFCs and refrigerator oil No specific direction of rotation, requiring no anti-rotation mechanisms Compensates for eccentricity and misalignment
