Over Two Decades of Vacuum Expertise
Founded in Nantong, Jiangsu in 2002, Nantong Zhongtian Machinery Manufacturing Co., Ltd. has grown from a liquid ring vacuum pump specialist into a trusted global OEM supplier serving customers in over 50 countries.
Our Story
Nantong Zhongtian Machinery Manufacturing Co., Ltd. was established in 2002 in Nantong, Jiangsu Province — a city with a long tradition of precision manufacturing and industrial engineering. We started with liquid ring and water ring vacuum pumps, building deep expertise in the technology before expanding our range.
Over more than two decades, we have grown our product portfolio step by step — from liquid ring pumps into rotary vane, Roots, dry screw, and claw vacuum technologies, and ultimately into complete engineered vacuum systems. Each expansion was driven by customer demand and backed by genuine manufacturing capability.
Today, Zhongtian Pumps supplies OEM customers, distributors, and end users in over 50 countries. Our products operate in chemical plants, pharmaceutical facilities, power stations, food processing lines, and paper mills on every continent. More than 20 years of manufacturing experience is behind every pump we ship.
What We Stand For
Engineering Integrity
We design and manufacture to specification — not to price. Every pump that leaves our factory has been tested and documented.
Technical Depth
Vacuum engineering is our only business. We invest in application knowledge and engineering talent to stay at the leading edge of vacuum pump technology.
Long-Term Partnership
We build relationships, not transactions. Our OEM customers and distributors stay with us because we deliver consistently and support them fully.
Global Perspective
We think globally — in product design, quality standards, documentation, and logistics. Our products are built for the world market.
