General‑Purpose Centrifugal Pumps
Engineered for non‑critical industrial applications, CME general‑purpose centrifugal pumps deliver reliable performance for cooling water circulation, glycol transfer, fire water service, and light hydrocarbon handling.
Constructed to ISO 5199 (Class II) and ISO 2858 for mechanical design and interchangeability, these pumps undergo performance testing in accordance with ANSI/HI 14.6 and ISO 9906. Available in close‑coupled, frame‑mounted, and inline configurations, they provide an optimal balance of efficiency, reliability, and lifecycle cost for auxiliary systems in refining, power, and chemical facilities.
Single‑Stage Centrifugal Pumps
Engineered for simplicity and cost‑effectiveness, our single‑stage centrifugal pumps are the industry standard for high‑volume, low‑to‑medium head applications. Constructed to ISO 5199 and ISO 2858, these units feature a robust radial impeller design ensuring stable performance and low NPSHr. The back pull‑out design allows for quick maintenance without disconnecting the piping, minimizing downtime. Performance is verified to ANSI/HI 14.6 standards, making them ideal for cooling water, HVAC, and general utility services.

- Efficiency: 32-85%
Multi‑Stage Centrifugal Pumps
Designed to deliver high discharge pressure within a compact footprint, our multi‑stage centrifugal pumps utilize a series of impellers on a common shaft to achieve significant head increases. Built to ISO 5199 standards, these pumps are suited for boiler feed water, high‑pressure washing, reverse osmosis (RO) systems, and water transfer over long distances. The rigid coupling and heavy‑duty bearing frame ensure reliable operation under continuous high‑pressure conditions, providing a dependable solution for demanding utility services.

Self‑Balancing Multi‑Stage Pumps
Offering the high‑pressure capabilities of traditional multi‑stage pumps without the wear issues of conventional balancing devices, our self‑balancing pumps feature a symmetric impeller arrangement that cancels axial thrust. This advanced design eliminates the need for balance discs and drums, drastically reducing maintenance costs and improving mean time between failures (MTBF). Ideal for high‑temperature condensate recovery, mine dewatering, and high‑rise building boosting, these pumps provide superior reliability for critical high‑pressure services.

- Head: 7.5-180 bar
- Efficiency: 32-84%
Split‑Case Centrifugal Pumps
Recognized for their high efficiency and ease of maintenance, our split‑case centrifugal pumps feature a horizontally split volute casing that allows access to the impeller and bearings without disturbing the suction or discharge piping. The double‑suction impeller design balances hydraulic axial forces and enables large flow rates with low suction cavitation risk. Compliant with ISO 5199, these pumps are the preferred choice for municipal waterworks, cooling water circulation in power plants, and large‑scale irrigation systems.
- Single Inlet Multi-stage Split Case Pump
- Dual Inlet Multi-stage Split Case Pump
- Flow Rate: 23.4-33005 m³/h
- Head: 0.95-36 bar
- Efficiency: 69-91%
Mixed‑Flow Pumps
Positioned between centrifugal and axial‑flow designs, our mixed‑flow pumps provide a unique combination of high flow rates and medium‑to‑high discharge heads. The impeller vanes impart both centrifugal and lift forces to the fluid, resulting in superior hydraulic performance. These pumps are particularly effective for applications involving large volumes of water with moderate head requirements, such as flood control drainage, circulating water for power stations, and agricultural drainage and irrigation. Available in both vertical and horizontal configurations to suit specific site constraints.
