Descrição

109 Series Water Pump Seal

The 109 series mechanical seal is a core precision component designed to prevent leakage in industrial pumps, pipeline pumps, and water ring vacuum pumps. Its design combines structural robustness with operational flexibility:

Precision Mating Faces: The rotating face (driven by the shaft) and the stationary face (fixed to the pump housing) are precision‑machined. Under the combined action of spring pressure and fluid pressure, they achieve intimate contact.
Fluid Film Lubrication: An extremely thin fluid film, on the order of microns, forms between the sealing faces. This film acts as a compliant cushion to prevent liquid from escaping along the rotating shaft, while also providing lubrication and heat dissipation at high rotational speeds - significantly reducing face wear.
Elastic Compensation: The assembly incorporates high‑strength springs and secondary sealing elements that automatically compensate for axial runout and installation misalignment, ensuring long‑term sealing stability.

Product Advantages & Application Benefits

Superior Materials - Adaptable to Diverse Service Conditions

For different pumped media, we offer various material pairings:

Seal Face Materials: High‑hardness Silicon Carbide (SiC), Ceramic, or high‑lubricity Carbon (Graphite), offering excellent wear resistance and chemical corrosion resistance.
Secondary Seals: Available in NBR, EPDM, or Viton® (FKM) high‑quality elastomers, reliably handling clean water, oils, industrial wastewater, and certain acid/alkali media.

Stable Operation - Extremely Low Maintenance Costs

Compared to conventional packing (gland packing), the 109 series mechanical seal offers significant advantages:

Near‑Zero Leakage: Dramatically reduces fluid loss, environmental contamination, and energy waste caused by dripping.
Long Service Life: Reduces maintenance frequency and downtime, ensuring continuous operation in water supply, drainage, environmental protection, and chemical production lines.

Technical Specifications

Parameter	Specification	Notes
Shaft Diameter Range	10 mm - 100 mm	Covers common industrial pump shaft sizes
Operating Pressure	≤ 1.2 MPa (12 bar)	Suitable for medium‑ and low‑pressure water supply & drainage systems
Operating Temperature	-20 °C to +120 °C	Depends on elastomer material (NBR / EPDM / Viton®)
Peripheral (Surface) Velocity	≤ 10 m/s	Compatible with standard motor speeds (1450 / 2900 rpm)
Allowable Axial Shift (Compensation)	± 0.5 mm	Provides good elastic displacement compensation
Balance Type	Unbalanced design	Simple construction; easy installation and maintenance

Key Advantages

Spring unit averted from the product so no sticking and clogging of the springs
Safe operation (no fractures) because of seal face locking by square pin
Suitable for pressure reversals
Operation in vacuum without additional seat locking possible
No damage of the shaft by a dynamically loaded O-Ring
Small installation sizes
Best suitable for conversions, no adaptations of the pump
Insensitive to solid containing and abrasive media
Advantages of a balanced seal even with plain shafts
Insensitive to shaft movements because of the stationary design

Applications

Water and waste water technology
Chemical industry
Refining technology
Dirty, abrasive and solid containing media
Fugitive hydrocarbons (no API seal!)
Sticky and stringy media
Chemical standard pumps
Sewage pumps

Technical FAQ: 109 Series Mechanical Seal

Q1: How does the 109 series seal perform in the complex operating conditions of a water ring vacuum pump?

A: Water ring vacuum pumps are prone to cavitation and pressure fluctuations during operation. The 109 series utilizes the compensating capability of its single‑spring design to respond rapidly to small axial movements. Additionally, we recommend selecting silicon carbide (SiC) seal faces to withstand mechanical shocks from dry running or fine abrasives present in the pumped fluid.

Q2: Why does my mechanical seal exhibit slight leakage immediately after startup?

A: A brief "break‑in" period may occur after initial installation. As long as the fluid film stabilizes within a few minutes, the leakage will stop on its own. If leakage persists, check whether the secondary seal was damaged during installation or if foreign particles have contaminated the sealing faces.

Q3: What advantages does the 109 series mechanical seal offer over conventional packing (gland packing)?

A: The core advantages are:

No shaft wear: Packing directly rubs against the shaft sleeve, whereas in a mechanical seal, wear occurs only between the rotating and stationary faces.
Lower power consumption: The coefficient of friction of a mechanical seal is extremely low, effectively reducing motor load.
No daily adjustment: Spring compression automatically compensates for face wear, eliminating the need for frequent manual gland adjustments.
