Communication Methods: We use a combination of on-site interviews, online meetings, and blueprint verification. If the client’s project site is under construction, we go to the site to meet with the project manager and operations team face-to-face. For remote clients, we use high-definition video calls to share project layouts and process flow diagrams, ensuring no information is lost.
Needs Analysis: We not only clarify basic operating parameters (e.g., conveying medium type: slurry / sewage / clear water / mud; medium concentration, particle size, temperature, corrosiveness; required flow, head, continuous operation time, start-stop frequency), but also focus on understanding application constraints (e.g., installation space, load-bearing capacity, power specifications, noise/vibration restrictions). We also identify implicit needs (e.g., energy-saving goals, ease of future maintenance, expected equipment lifespan) to create a 'Customer Needs Checklist.' After client confirmation, this list becomes the core basis for all subsequent work.

Solution Development: We draw on experience from over 100 similar projects (e.g., mining slurry transport, municipal sewage treatment, industrial circulating water systems) and refer to national standards like the 'Design Specifications for Industrial Pumps' and other advanced industry standards. We use CAD 3D modeling and CFD fluid dynamics simulation software to pre-run pump performance, avoiding issues of oversized pumps wasting energy or undersized pumps failing to meet demands.
Core Solution Content: We specify the pump model (e.g., a high-chrome alloy impeller slurry pump for high-abrasion slurry, or a double suction pump for high-flow drainage), and core components (e.g., corrosion-resistant seals, IE3 high-efficiency motors). We also provide a 'Technical Advantage Description' (e.g., 'this configuration can reduce energy consumption by 15% and extend service life by 2 years'), a cost estimate (including unit price, installation materials, and long-term maintenance costs), and 1-2 alternative options (e.g., a cost-effective option for limited budgets, or a high-end option for long-term benefits). We thoroughly explain the solution logic to the client and refine it based on feedback, culminating in a 'Product Configuration Confirmation Sheet.'

Key Clause Details:
Product Specifications: We specify critical parameters like pump model, materials (pump body/impeller), motor power, dimensions, and weight, with a product parameter sheet as an appendix.
Technical Requirements: We agree on standards (e.g., GB/T 5657-2013 'Technical Conditions for Centrifugal Pumps'), performance indicators (e.g., efficiency not less than 95% of design value, noise ≤85dB), and environmental requirements (e.g., compliant with national environmental standards, no harmful emissions).
Delivery Timeline: We specify production start and end times, logistics methods (e.g., land/sea/air transport, with special packaging if needed), and arrival time. We also state that 'in case of force majeure (e.g., raw material shortages), we will provide 72 hours of written notice to the client and negotiate adjustments.'
After-Sales Clauses: We define the warranty period (e.g., 1-year free warranty, with core components extended to 2 years), service response mechanism (24-hour free technical consultation, on-site service within 48 hours for emergencies), and repair/replacement rules (free replacement of parts for non-human damage within the warranty period).
Additional Agreements: We clarify acceptance standards (e.g., clients must count and accept goods within 3 working days after arrival, and sign an 'Acceptance Certificate' after installation and commissioning) and payment terms (e.g., 30% advance deposit, 50% before shipment, 20% after acceptance) to prevent future disputes.

Raw Material Control: All materials (e.g., steel, motors, seals) are procured from certified suppliers. Upon arrival, we verify material analysis reports and certificates. Key components (e.g., impellers, pump shafts) undergo random inspections (e.g., hardness tests, composition analysis), and non-conforming materials are rejected.
Production Process Control: We adopt a 'standardized procedure + regular inspection' model. We create 'Production Operation Manuals' that specify operational norms for each step (e.g., impeller casting temperature controlled at 1500-1550℃, machining tolerance ≤±0.05mm; seal compression controlled at 2-3mm during pump body assembly). Quality inspectors sign off after each step, and critical steps (e.g., impeller dynamic balance testing, pump body pressure testing) have a 'double-check' system.
Progress Tracking: We use a production management system (MES) to provide real-time updates. We send weekly 'Production Progress Reports' to clients. If there are delays (e.g., parts are late), we immediately activate an emergency plan (e.g., adjust production schedules, coordinate backup parts) to ensure on-time delivery.
Eco-Friendly Production: Our production process uses water-recycling cooling systems and dust collectors to reduce wastewater and exhaust gas emissions. Scrap materials are centrally recycled, ensuring compliance with national environmental regulations.

Factory Inspection: All products must pass a 'Triple Inspection':
Performance Testing: We conduct real-world tests on a dedicated test bench to verify that flow, head, efficiency, and NPSH meet design requirements. We record data and generate a 'Performance Test Report.'
Sealing Test: We pressure-test the pump body and pipe connections (at 1.2 times the working pressure for 30 minutes) to check for leaks.
Appearance and Safety Inspection: We check for uniform, scratch-free paint finishes, secure component connections, and standard motor grounding and insulation performance, and attach an 'Appearance Inspection Record.' Only after passing all inspections is a 'Product Qualification Certificate' issued, allowing the product to leave the factory.
Delivery Process:
Packaging Protection: We use customized packaging (e.g., wooden pallets + shock-proof foam, labeled 'Fragile' and 'This Side Up') based on product size and transport method.
Inventory Handover: Before shipping, we confirm product and accessory quantities with the client (including user manuals, maintenance guides, wear part spares, and special tools) and issue a 'Shipping Manifest.'
Logistics Tracking: We use our long-term logistics partners, provide tracking numbers, and give clients real-time updates on their shipment's location. Upon arrival, we assist with unloading and, after confirming no transport damage, have the client sign a 'Delivery Confirmation.'

Preparation: Three working days before installation, we confirm site conditions with the client (e.g., power connection, pre-embedded pipes in place, and a clean installation area). Our engineers arrive on-site with an 'Installation and Commissioning Manual,' specialized instruments (e.g., pressure gauges, flow meters, tachometers), and spare parts.
Installation Guidance: Based on the installation drawings, we guide the client's team or complete the equipment positioning ourselves (ensuring a horizontal error of ≤0.1mm/m), pipe connection (proper seal installation to prevent leaks), and motor wiring (verifying power parameters to prevent reverse connections). During the process, we explain key installation points and safety precautions to the client's operators.
Commissioning and Operation:
No-Load Test: We check motor direction, bearing temperature rise, and noise levels for normalcy. If any issues arise (e.g., excessive noise), we troubleshoot immediately (e.g., adjust motor wiring, replace bearings).
Load Test: We gradually adjust flow and head according to the client's needs, record operational parameters, and ensure they meet production requirements. After 24 hours of stable, fault-free operation, we invite the client to verify on-site.
Operational Training: We demonstrate equipment startup, parameter adjustment, daily checks (e.g., lubricant level, seal leak inspection), and simple troubleshooting methods to the client's operators, ensuring they can operate independently. Finally, a 'Certificate of Installation and Commissioning' is signed, confirming normal equipment operation.

Customer Profile Management: We create a dedicated electronic file for each client, recording a 'Product Information Sheet' (model, parameters, installation date), a 'Service Record' (installation/commissioning notes, maintenance history), and an 'Operation Data Log' (client-provided performance data) to facilitate precise service.
Regular Follow-ups: We have a 'Tiered Follow-up Plan':
Short-term: A phone call within 1 week of installation to confirm equipment status and answer operational questions.
Mid-term: An on-site inspection every 3 months to check equipment wear (e.g., impeller wear, seal aging), clean oil and debris, and calibrate operational parameters.
Long-term: A comprehensive maintenance visit once a year to replace wear parts (e.g., rings, bearings), evaluate equipment efficiency, and provide energy-saving suggestions (e.g., adjusting operating frequency).
Needs Response: When a client reports a fault or a new need, we respond within 24 hours. If it can be solved by phone (e.g., parameter adjustments), we provide immediate guidance. For on-site issues, we dispatch an engineer within 48 hours and follow up for 1 week after repair to confirm no recurrence. We also use client feedback to optimize our product design (e.g., upgrading impeller materials for specific conditions) or service processes (e.g., shortening follow-up intervals) to continuously improve the customer experience.
