Gleitringdichtung-Direkt / Gleitringdichtung mechanical seals and spare parts

Gleitringdichtung-Direkt / Gleitringdichtung industrial mechanical shaft seals deliver dependable leakage defense across industrial pump and compressor systems.

Gleitringdichtung conical spring mechanical seals

Gleitringdichtung mechanical seals with conical helical springs are engineered for pumps handling clean and mildly contaminated liquids. The conical spring delivers rotational drive via shaft interference fit, ensuring consistent axial loading across sealing interfaces.

Direct torque transmission through spring fit without external set screws
Secondary elastomeric O-ring provides sealing along precision shaft diameters
Available in right-hand and left-hand spring coiling to match shaft rotation
Tribological faces manufactured from silicon carbide, tungsten and graphite

Gleitringdichtung elastomer bellows shaft seals

Gleitringdichtung elastomeric bellows seals are designed for pump shafts without risk of fretting wear along contact sleeves. The convoluted rubber bellows absorbs axial play and angular runout, preventing seal hang-up and safeguarding shaft surfaces during operations.

One-piece elastomer bellows eliminates fretting wear on delicate pump shafts
Effective compensation for angular misalignment and dynamic rotor end play
Non-clogging profile resistant to slurry build-up within seal housing chambers
Bellows materials include NBR, EPDM, and FKM formulated for temperature ranges

Gleitringdichtung cylindrical spring seals with rubber sleeve

Gleitringdichtung mechanical seals with parallel cylindrical springs operate independently of shaft rotational direction. An integrated protective rubber sleeve isolates spring coils from fluid contact, shielding the mechanism from fiber fouling and abrasive suspended solids.

Symmetric cylindrical spring functions reliably in either rotational direction
Protective elastomer sleeve isolates spring coils from abrasive fluid particles
Extended service intervals within wastewater, drainage, and effluent pump units
Straightforward mounting on smooth pump shafts conforming to industrial metrics

Gleitringdichtung hydraulically balanced mechanical seals

Gleitringdichtung balanced mechanical seals are engineered for process systems running under elevated system pressure. Stepped shaft geometry minimizes hydraulic closing forces across sealing faces, moderating thermal generation and mechanical wear along friction surfaces.

Reduced balance ratio tailored for steady operation under pressure to 25 bar
Diminished frictional heating and low wear rates across precision seal faces
Preserves stable hydrodynamic fluid lubricating film at elevated shaft speeds
Suited for boiler feed water pumps, chemical autoclaves, and reaction vessels

Gleitringdichtung wave spring and multi-spring compact seals

Gleitringdichtung compact mechanical seals with wave springs or multiple coil spring blocks are developed for restricted seal chambers. The multi-point spring layout distributes closing forces evenly around sealing perimeters, maintaining parallel face alignment.

Short axial length fitting standard stuffing box dimensions of DIN EN 12756
Uniform circumferential load distribution preventing localized face tipping
High fatigue endurance of wave spring alloys under dynamic cycling regimes
Available in Hastelloy and Inconel spring alloys for severe chemical streams

Gleitringdichtung stationary counter rings and clamping collars

Gleitringdichtung manufactures stationary counter rings and Klemmringe clamping collars for rotating assemblies. Precision optical lapping of sealing faces ensures leak-tight performance when paired with rotating seal rings across demanding industrial pump units.

Stationary seat profiles G6, G9, G4, and G60 with pin or O-ring anti-rotation
Optical lapping provides face flatness deviations below two light bands
Klemmringe locking collars with radial clamping screws for secure shaft hold
Elastomeric seat gaskets in oil-resistant, high-temperature fluoropolymers

Operating principles and design of Gleitringdichtung conical spring seals

Gleitringdichtung conical spring mechanical seals deliver dependable sealing across industrial centrifugal pumps handling clean and mildly contaminated liquids.

The kinematics of the helical spring rely on tight interference fit along rotating shaft surfaces, delivering drive torque without requiring external drive pins or keyways.

During assembly, matching spring coiling direction with shaft rotation is essential: under forward rotation, torque tightens the spring coils around the shaft, ensuring continuous axial seating load against stationary counter faces without slippage during startup.

Advantages of elastomer bellows mechanical seals in industrial pump applications

Elastomer bellows shaft seals from Gleitringdichtung are engineered to resolve fretting wear along pump shaft sleeves. In conventional designs, dynamic secondary O-rings slide axially during shaft end play, generating fretting grooves and shaft damage.

In this bellows configuration, the rubber collar is clamped tightly onto the shaft, while axial vibrations, runout, and angular misalignment are absorbed by flexible convolutions.

The seamless bond between bellows and seal ring carrier prevents chemical deterioration, ensuring unrestricted floating mobility of the rotating face.

Cylindrical spring configurations with elastomer protective sleeves for slurry services

Gleitringdichtung cylindrical helical spring seals equipped with protective elastomer sleeves are deployed within slurry, wastewater, and drainage pumps carrying suspended solids and fibrous particles.

The parallel spring geometry is non-directional, maintaining identical performance under bidirectional or reverse shaft rotation.

The integrated elastomeric sleeve fully shields metallic spring coils from direct exposure to the fluid flow, preventing slurry accumulation and coil clogging, which extends routine maintenance intervals across heavy industrial pumping stations.

Hydraulic balancing principles across high-pressure mechanical seal applications

For processing plants running at pressures above ten bar, Gleitringdichtung manufactures hydraulically balanced mechanical seals. In standard unbalanced assemblies, system pressure imposes excessive hydraulic load on sealing faces, disrupting lubricating fluid films and causing rapid face wear.

In balanced configurations, stepped shaft sleeves reduce the effective hydraulic area exposed to line pressure. Consequently, closing force ratios are moderated, maintaining a resilient fluid film between rotating faces while significantly decreasing frictional heat generation and power consumption.

Compact wave spring and multi-spring assemblies for standardized seal chambers

In modern pump equipment conforming to DIN EN 12756 dimensions, axial installation envelopes are compact, preventing the use of long coil springs.

For these installations, Gleitringdichtung supplies compact mechanical seals featuring wave springs or multi-point mini coil spring blocks spaced along the retainer circumference.

This layout provides a uniform axial pressure field, preventing angular tipping of rotating rings relative to the shaft axis. Wave spring alloys withstand dynamic cycling and high-frequency vibrations in severe chemical services.

Tribological face pairing selection and stationary counter seat configurations

The operating longevity of Gleitringdichtung-Direkt / Gleitringdichtung mechanical seals depends directly on tribological face material pairings and stationary seat geometries.

For clean fluids running at elevated speeds, silicon carbide against resin-impregnated synthetic carbon delivers low friction and optimal thermal conduction. For abrasive applications, hard pairings such as silicon carbide against tungsten carbide prevent erosion.

Standard stationary seats G6, G9, and G60 provide secure anti-rotation, while Klemmringe collars ensure positive shaft clamping.
