We act with urgency to deliver innovative and high quality turbomachinery, energy and lifecycle solutions

When it comes to pumps, performance is everything. Processes and operations depend on them, often transporting hazardous or corrosive liquids. Pumps always need to be in working order - many applications require continuous operation and downtime costs money. Unscheduled or sudden part failure can be disastrous.

by: Sulzer Pumps Finland Oy

Procuring spare parts is a crucial decision-making process. Customers have ever more options, with OEM manufacturers vying for attention alongside a growing network of competitors and imitation products. Cut prices present an eye-catching appeal, but short-term savings do not always represent true value over time. Sulzer has been developing pumping solutions for the process industry for over 100 years. When purchasing a Sulzer product, a customer buys into a vast network of expertise and knowledge available from the moment an agreement is made through to when the pump is retired from action.

Keeping customers up to speed

Sulzer’s global Customer Support Services network carries out regular mill surveys and energy audits to ensure optimal performance. The service experts can replace ageing spare parts with technologically superior alternatives. Third party suppliers are not aware of the full system setup and thus not able to advise on the best steps forward. Regular consultations with Sulzer help extend the lifecycle of the pumping systems by ensuring more reliable operation, fewer unexpected failures and lower lifecycle costs. Sulzer also provides a full range of inventory management to support customers to manage their stock and to reduce inventory costs.

We specialize in pumping, agitation, mixing, separation and application technologies for fluids of all types

Peace of mind

With Sulzer as OEM provider of spare parts, plant operators can get the best out of their pumping systems.

The modular approach of Sulzer’s pumping solutions is designed to make operation as convenient and functional as possible. Maintenance or upgrading can be carried out easily, and the modular structures allow the customers to manage with less spare parts. This approach makes it fairly easy for competitors to replicate spare parts. But what might seem like a straightforward duplicate can cause incremental damage. A study analysing the hydraulic performance of the impeller of one of the more reputable third-party suppliers discovered that the part had a major deficiency in its output. In order to achieve the required output, the pump had to be run faster, using more energy (Figure 1). This added € 2,000 per year in energy cost per part, easily outweighing the € 600 saving made in the purchase price. The impeller also had deficiencies in mechanical quality, such as back vanes that were too high and runouts that exceeded tolerances. The manufacturing material was not as described. Sulzer always balances impellers to meet the allowed tolerances – this is not always the case with third party parts. Extensive undue vibration placed considerable stress upon pumping performance, while mechanical contact with the casing cover led to higher power consumption. There was potential of seizure if left unaddressed. In a separate case, the same manufacturer was responsible for replacing an old pump made by Scanpump (now part of Sulzer). The third party’s replacement pump failed completely, and the customer contacted Sulzer. The pump was delivered promptly and has proved a success. These examples represent some of the best third-party parts available from a comparatively reliable manufacturer.

Less-than-ideal performance is one thing, but the worst-case scenario is far more problematic. Pump failure in a slurry mill or sewage works, where potentially corrosive and hazardous materials are being used, can be severely problematic to a vast community and, at worst, fatal.

Long-term trust over short-term gains

The true value of selecting OEM spare parts is evident, and several long-term customers have returned to Sulzer. Two such clients, a major packaging provider and a pulp mill respectively, decided that the technical support they receive from Sulzer is unmatched by other competitors. A third-party parts provider would simply be unable to match Sulzer’s in-depth knowledge that comes with having designed, constructed and installed all parts of the pump solution.

Sulzer has been driving industrial processes all over the world for over a century, refining the pumping solutions for the best performance.
