Product Description

Parameter	Value/Description	Unit/Note
Model	QT-APV	Single/double mechanical seals designed for APV pump series (e.g., C-Pump, Mixproof)
Seal Type	- Hygienic Single Seal (for clean media) - Double Mechanical Seal (for dual-containment applications)	Single seal for non-hazardous fluids; double seal with barrier fluid for high-risk environments
Face Materials	- Primary: Silicon Carbide (SiC) - Secondary: Carbon Graphite with PTFE Impregnation	SiC offers high wear resistance; graphite ensures low friction in sanitary setups
Housing Material	Stainless Steel 316L (Electropolished)	Surface roughness: Ra ≤0.6 μm, compliant with EHEDG and 3-A standards
Pressure Range	- Single: 0 - 1.2 - Double: 0 - 2.0	MPa	Double seal supports higher differential pressures for containment
Shaft Diameter Range	20 mm - 80 mm	Matches APV pump shaft dimensions (check model-specific compatibility)
Maximum Rotational Speed	5000	RPM	Suitable for high-speed pumping in dairy and chemical processes
Temperature Range	-20°C ~ 150°C (Standard) - Up to 200°C (with FFKM elastomers)	EPDM elastomers (standard) for food-grade use; FFKM for steam sterilization (SIP/CIP)
Leakage Rate	≤0.3 ml/h (Single) ≤0.05 ml/h (Double)	Exceeds ISO 21049 and FDA 21 CFR Part 177 requirements for hygiene
Installation Type	Cartridge-Ready (Clamp-Fit Design)	Tool-free installation for quick replacement in hygienic pipelines
Elastomer Material	EPDM (FDA-compliant, standard) - FFKM	EPDM: pH 2-12 compatibility; FFKM: Resistant to aggressive chemicals (pH 0-14)
Standards Compliance	3-A Sanitary Standard 6040-2018, EHEDG, ASME BPE, CE	Certified for use in food, beverage, and pharmaceutical industries
Key Features	- Mixproof Design (for double seals to prevent cross-contamination) - Self-Draining Geometry - Smooth Bore to Reduce Product Retention	Critical for applications requiring zero leakage (e.g., pharmaceutical mixing, allergen-free production)

Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.

Mechanical sealing adopts the principle of mechanical friction sealing, which has excellent sealing performance, which can effectively prevent leakage and protect the safety of the environment and equipment. Compared with traditional packing seals and rotary seals, the sealing effect of mechanical seals is more reliable.

Our products are made of high quality materials and manufacturing processes, with a long service life and low cost of use. It can effectively reduce the maintenance costs and operating costs of equipment .

Our mechanical seals are designed to be easy to service and replace,simply by removing the sealing components and replacing the sealing surface and sealing ring. Compared with other sealing forms, our products are more convenient to repair and replace.

Mechanical seal is suitable for high temperature, low temperature, high pressure, vacuum and corrosive media and other complex environment, to ensure the stable operation of the equipment.
