On March 12, 2025, the first submersible electric pump, independently developed by the ZPEC Equipment Group at its Shanghai Lingang Base, successfully completed production and manufacturing and has passed joint debugging and testing. All technical indicators have reached the relevant national standards, and will be sent to the oil field for industrial testing. The successful production of this product not only enriched ZPEC's product variety in petroleum equipment manufacturing, but also demonstrated ZPEC's technical strength and innovation capabilities in the field of petroleum equipment manufacturing.

Since the establishment of ZPEC’s Submersible Electric Pump Division in November 2024, the R&D and Production Teams have worked overtime to trial-produce submersible electric pumps based on early on-site exchanges, program demonstration, drawing design, and component manufacturer research. In combination with the actual oil production in the Tenge Oilfield in Kazakhstan, they optimized and designed a set of submersible electric pumps that are suitable for small flow, high head, high sand production in the well fluid, and high oil-gas ratio. On March 6, 2025, the Company completed the production of the first submersible electric pump unit.

During the joint commissioning and testing on March 8 - 9, cross-departmental teams, including the Shanghai Equipment Production and Operation Department, Intelligent Research Institute, Digital Management Center, and Zhongman Electric, collaborated to complete no-load tests, downhole sensor data collection, and host computer remote monitoring tests.

In the next step, the Submersible Electric Pump Division will collaborate with multiple departments to continue to carry out intelligent upgrades to submersible electric pumps. At the same time, in order to facilitate overseas personnel to operate the equipment, it is planned to add a Russian operating interface to the touch screen of the intelligent control station based on the Chinese and English operating interfaces.

Submersible electric pumps are advanced process equipment for oil field production. At present, the electric pump production method of the Tenge Oilfield is to rent foreign brands of submersible electric pumps, which is not only expensive, but also technically limited. After the batch use of ZPEC’s submersible electric pumps, this problem will be completely solved. (Liu Wendong, Equipment Group)
