Transneft Oil Pumps plans to supply four ANM 4500-650 pumping units to the Caspian Pipeline Consortium (CPC) in 2026. Dmitry Tumanov, general director of Ural Dynamic Machines, gave the schedule on Feb 5, 2026. The overall programme comprises 12 units, including an already manufactured prototype; the other 11 are scheduled to enter production during 2026–2027.
The Chelyabinsk manufacturer produces pumps and replacement components. Its factory entered full-cycle operation in 2016 after investment of RUB4.15 billion. Annual design capacity is 160 horizontal pumps and 20 vertical pumps. Ural Dynamic Machines manages both Transneft Oil Pumps and Russian Electric Motors, which supplies high-voltage motors.
Factory tests and equipment
The prototype completed comprehensive acceptance tests in Chelyabinsk on Mar 12–13, 2025, following preliminary pump and motor tests that February. CPC confirmed that the tested characteristics met the manufacturer's specifications, the design requirements and GOST 32601-2022. The equipment combines an NM 4500-650 pump with an AN860A-8300 asynchronous motor rated at 8.3 MW.
Both machines sit on a common skid. Their auxiliary equipment includes the following systems:
- Lubricating oil and leak collection;
- Drainage, hazardous-vapour relief and mechanical-seal supply;
- Instrumentation, temperature monitoring and vibration monitoring.
CPC supplied ventilation and power equipment for an integrated testing arrangement capable of examining pump units with flow rates up to 15,000 cubic metres per hour. That figure describes the test system's capacity.
Contract and power connections
CPC-R and Russian Electric Motors signed the 11-unit contract at Russian Energy Week on Oct 16, 2025. The agreement covers manufacture, delivery, installation supervision and commissioning, including common lubricating-oil systems. These units form part of CPC's planned replacement of gas-turbine-driven pumps with electric-motor-driven equipment.
The replacement programme covers A-PS-4A, Komsomolskaya and Kropotkinskaya stations in Russia. The infrastructure plan includes variable-frequency-drive shelters and additional cables. CPC also planned 110 kV substations and power lines for A-PS-4A and Kropotkinskaya, with respective line lengths of 55 km and 11 km. Rossety was to build Komsomolskaya's external power facilities using CPC-R funding.
Prototype trial at PS-7
During January 2026, CPC, Transneft and maintenance contractors installed the industrial prototype in the main pump house at PS-7 in Krasnodar Krai and connected its controls and electricity supply. CPC's site-testing programme was scheduled to last several months. The prototype was intended for subsequent operation at Kropotkinskaya.
CPC's pipeline links western Kazakhstan and Russian oil fields with the marine terminal at Novorossiysk. The four deliveries remain a manufacturer's plan for 2026.
