1. OEM Supplier of Choice

System longevity and ensuring maximum return on investment are key priorities for all Celeros Flow Technology’s customers. With this in mind, we strive to supply and maintain pumps that are capable of setting new benchmarks in terms of uptime, as well as specification compliance.

We appreciate that specifying and installing flow control equipment is just the start of the journey. Even the best pump needs regular maintenance to make certain it continues to achieve required performance specifications. General wear and tear, as well as other factors like changing operating conditions, can lead to pumps delivering less than peak efficiency over time.

Our highly adept engineering staff are ready to attend to all your operational needs. Their activities cover servicing and maintenance, parts repair and replacement, the upgrading of pumps to address new process requirements, holistic system optimization, etc. They are also able to identify and resolve potential problems at the earliest possible stage.

Raising Pump Efficiency Levels

Raising Pump Efficiency Levels

The largest contributor to the cost of running a pump is the energy it consumes. Any factor that lowers the pump’s operational efficiency increases running costs.

Pumps may run less efficiently for various reasons, significantly increasing energy costs. Examples include changes in process parameters or conditions, alterations in the ambient surroundings, general wear over time, and changes to the fluid’s properties.

Celeros Flow Technology uses sophisticated analysis tools to estimate the effectiveness of improvements, allowing different upgrade scenarios to be investigated before investment. These tools apply to both our equipment and third-party equipment, leading to marked efficiency improvements, reduced running costs, and extended operational lifespan. The return on investment time is very short, often just a few months.

Rapid Parts Supply to Minimize Downtime

Rapid Parts Supply to Minimize Downtime

Universally recognized as a leading pump manufacturer, Celeros Flow Technology has thousands of units deployed globally across various applications. We are uniquely positioned to advise on metallurgy upgrades to maximize equipment longevity.

Case study example:

Excessive erosion on a KSMK pump in an oil extraction plant negatively impacted Mean Time Between Failures (MTBF). The pump, in operation for less than 4 years, showed signs of excessive wear. ClydeUnion Pumps proposed a triple solution to upgrade the BB2 pump, including advanced tungsten carbide coatings to mitigate erosion. Compared to expensive equipment replacement, our solution delivered cost savings and increased reliability, reducing maintenance costs and downtime. This case exemplifies our ability to enhance equipment performance and extend operational life through targeted upgrades, providing significant value to our customers.

Hydraulic Re-Design For Process Changes

Hydraulic Re-Design For Process Changes

Essential to any pump’s operation is its hydraulic performance, measured in flow, pressure, and power consumed. Celeros Flow Technology’s technical expertise allows us to redesign any installed unit to optimize its operational requirements. Often, this involves finding an alternative hydraulic setup from our extensive portfolio of legacy designs. We also supply fully optimized clean sheet designs using the latest software tools when required.

Case study example:

Our US oil & gas customer needed a hydraulic re-rate of a third-party multi-stage pump to new conditions while maximizing efficiency. We found the most cost-effective method was to trim the impellers to match the desired flow and restore running clearances to API 610 standards. This hydraulic re-rate achieved a 20% reduction in operating costs, a 30% reduction in energy consumption, and an ROI within 12 months.
