China's industrial maintenance and procurement calendar has a fixed rhythm. Every year, plant engineers from chemical facilities, power stations, water treatment works, and industrial processing plants across the country come to Shanghai to evaluate pump, valve, and compressor suppliers. CPVF — the China International Pump, Valve, Compressor and Pipeline Fair — is that event. It is distinct from Flowtech China in focus: where Flowtech skews toward municipal and building services applications, CPVF concentrates on the process industry — the heavy-duty, high-pressure, chemically aggressive environments where pump and valve selection decisions carry the most technical weight.

The show runs annually at the Shanghai New International Expo Centre and consistently attracts over 1,000 exhibitors across a 50,000-plus square metre footprint. The visitor base draws heavily from the petrochemical and chemical industry — SINOPEC, CNPC, and their downstream operating units send procurement and engineering teams who are specifying replacement and expansion equipment for facilities running continuously, where unplanned downtime is measured in millions of yuan per hour. Getting the pump specification wrong is not a budget problem. It is a production problem.

The Process Industry Focus

Process industry pumps are a technically demanding category. A centrifugal pump handling hot, corrosive chemical slurry at 200 bar requires seal technology, impeller metallurgy, and casing design that is fundamentally different from the same rated pump in a clean water application. CPVF concentrates the supply side for these demanding applications: magnetic drive pumps for hazardous fluid handling, canned motor pumps for leak-free service, high-temperature process pumps for refinery applications, and the multistage high-pressure pumps used in boiler feed service and reverse osmosis systems.

Hydraulic pumps appear at CPVF primarily in the context of hydraulic power units for industrial press applications, offshore platform equipment, and the hydraulic systems used in chemical plant actuator drives. The buyer community for these products overlaps with the process pump buyers — the same plant engineer responsible for a refinery's process pump fleet is often also responsible for the hydraulic systems in the refinery's cracking unit presses and lifting equipment.

Quick Reference

Compressor and Sealing Technology

Compressors at CPVF range from small reciprocating units for instrument air supply to large centrifugal and axial flow machines for process gas service. The sealing technology section — mechanical seals, gland packings, gaskets, and the seal support systems that maintain process fluid containment — is one of the show's most technically specific zones. Seal failure is the primary cause of pump unplanned downtime in process industry applications, and Chinese industrial operators have become sophisticated buyers of seal technology following decades of experience with the consequences of inadequate sealing in high-pressure, high-temperature, and chemically aggressive service.

For international hydraulic pump and component manufacturers, CPVF offers a route into the Chinese process industry that is distinct from the construction and mobile equipment markets targeted by Flowtech China and the bauma CHINA platform. The process industry buyer community attends different shows, uses different procurement channels, and evaluates products on different criteria — specifically, the ability to demonstrate long mean time between failures in continuous operation and to provide local spare parts and service support. CPVF is the most efficient annual platform for building those relationships at scale.
