Professional FAQ: 175QJR Deep Well Submersible Pump

What materials are used in 175QJR Deep Well Submersible Pump construction?

Core wetted parts: Stainless steel (SS304/316) for casings and impellers; cast iron or bronze for support and reinforcement. All materials exceed ISO 2858 corrosion/abrasion test standards.

How does the double mechanical seal system work?

It comprises two precision-balanced seals (Primary: SiC/SiC, Secondary: Graphite/Ceramic), creating dual barriers against fluid ingress and extending pump operational life, even under dry-run conditions.

What is the typical installation depth and cable standard?

Standard models are rated for immersion up to 140 meters (API 610), using strictly IEC 60245-compliant waterproof cables with a PU or rubber sheath, resistant to abrasion and hydrolysis.

Which international certifications do the pumps possess?

All 175QJR Deep Well Submersible Pump products are manufactured under ISO 9001, ISO 9906, CE, and relevant IEC standards, ensuring global compatibility and safety.

What are the motor protection features?

Each motor offers IP68 ingress protection, Class F insulation, integrated thermal overload sensors, and is tested against IEC 60034/IEC 61800 requirements for electrical safety and efficiency.

What are the standard warranty and after-sales services?

All pumps come with a 24-month warranty (with extension up to 36 months for bulk/OEM orders). Post-sale support includes installation guidance, field commissioning, and 24/7 technical hotline.

Can the pump be customized for aggressive/acidic water?

Yes. Options include Duplex stainless steel, titanium alloy, or specialized coatings, with seal and cable upgrades to guarantee performance in high-chloride or acidic conditions.
