Jiangsu Haifa Machinery Manufacturing Co., Ltd.

Chemical pumps are not only core equipment in petrochemical, coal chemical, fine chemical, environmental water treatment, and high-temperature high-pressure conveying systems, but also impact the safety, continuity, and energy consumption of plant operations. Jiangsu Haifa Machinery Manufacturing Co., Ltd., through years of technical accumulation and service system development, has focused on products such as API610 chemical process pumps, API685 magnetic drive pumps, high-temperature thermal oil pumps, corrosion-resistant chemical pumps, vertical barrel pumps, continuously enhancing its pre-sale, in-sale, and after-sale service capabilities. In accordance with the requirements GB/T 27922-2011 "Evaluation System for Commodity After-Sale Service," the company steadily improved its customer service processes, traceability mechanisms, on-site response capabilities As a manufacturer deeply rooted in the chemical pump industry, we understand that what customers purchase is not just a pump, but a conveying solution capable of stable operation.

During the pre-sale, Jiangsu Haifa professional selection and technical confirmation based on provided by the customer, including medium name, flow rate, head, temperature, density, viscosity, inlet pressure, net positive suction head available (NPSHa), corrosiveness, particle content, and explosion-proof rating. For high-temperature oils, acid-alkaline corrosive media, flammable and explosive media, and low NPSH conditions, we professional factors such as performance, NPSH margin, mechanical seal plan, and material compatibility to help mitigate selection risks.

During in-sale phase, the places strong emphasis on contract review production progress tracking, quality inspection, and delivery management. Each pump is manufactured in accordance with design drawings process documents, and inspection specifications, with control over key items such as impeller balancing, pump casing hydrostatic testing, assembly concentricity, bearing temperature rise, vibration values, and seal reliability. For key products like API610 chemical process pumps, high-temperature pumps, and magnetic drive pumps, we pay extra attention to operational stability, seal safety, and of subsequent maintenance, ensuring goodability before equipment delivery.

During the after-sale phase, Jiangsu Haifa continuously improves its rapid response mechanism, offering customers services such as installation guidance commissioning, fault diagnosis, spare parts supply, maintenance and repair, technical modifications, and operational optimization. For common on-site issues, such as mechanical seal leakage, excessive bearing temperature rise, abnormal pump vibration, cavitation, insufficient flow, or head deviation, the company's technical personnel can analyze the situation based on on-site data and propose corrective solutions. When necessary, they can assist customers in optimizing seal flushing, adjusting operating conditions, upgrading material configurations, or energy-saving modifications for pump units.

At Jiangsu Haifa Machinery Manufacturing Co., Ltd., we generally believe in service management that the competitiveness of industrial equipment companies stems not only from the itself but also from lifecycle service capabilities, lifecycle service, preventive maintenance, reliability management, and customer satisfaction improvement. Based on this philosophy, Jiangsu Ha has gradually upgraded its after-sale service from "pass repair" to a service model of "proactive prevention, rapid response, and continuous improvement."

In the, Jiangsu Haifa Machinery Manufacturing Co., Ltd. will to reference the GB/T 27922-2011 evaluation system, steadily enhancing the standardization,, and internationalization of its chemical pump product services, providing more reliable products and service support for domestic and international petrochemical refining, environmental protection, new energy, and high-temperature high-pressure fluid conveying projects.
