A reciprocating pump-also known as a piston or plunger pump-is a positive displacement device that delivers precise, high-pressure fluid transfer via cyclic piston motion. Renowned for volumetric efficiency above 90%, far exceeding centrifugal pumps under variable loads, it stands as the backbone for high-pressure, low-flow applications across oil and gas, chemical processing, power generation, and cryogenic industries.
China's reciprocating pump sector has undergone remarkable transformation over the past two decades. Fueled by industrialization, energy infrastructure expansion, and technological self-reliance policies, the nation has evolved into a global manufacturing powerhouse for reciprocating pumps. In 2023, China's reciprocating pump market reached USD 1,293.6 million, projected to grow at a 5.8% CAGR through 2030, driven by demand for high-pressure cryogenic pumps, oilfield injection pumps, and chemical dosing pumps.
