When it comes to positive displacement pumps, NETZSCH and SPX are among the most recognized players on the market when it comes to stronger and effective lobe pumps. This particular blog aims to compare NETZSCH lobe pumps with those of SPX lobe pumps with respect to their applications, performance and design features with an intention of bringing out the differences between the two lobe pumps.
Design and Construction
When it comes to materials used in construction, NETZSCH and SPX lobe pumps are quite competitive as the materials used guarantee sustainability and longevity of the pumps. However, there are some important aspects that set them apart in terms of their construction:
NETZSCH Lobe Pumps: NETZSCH lobe pumps are specifically designed for high potential applications. The unique feature noticed with their pumps is the compact configuration and simple maintenance, with options that reduce component degradation. Less structural breakdowns are experienced while using NETZSCH pumps because of the removable lobes which quicken the maintenance process.
SPX Lobe Pumps: SPX has placed emphasis on hygienic and clean designs mostly in the food and beverage, pharmaceutical and biotechnology industries. As a result, the internal surfaces of sanitary lobe pumps are polished and finished minimizing contamination. SPX pumps are also highly composed with toughness and internal leakage is minimized by the use of advanced sealing suffices.
Performance
Both manufacturers have lobe pumps of good performance, however this may vary depending on the pump model and the intended use.
NETZSCH Performance: NETZSCH lobe pumps stand out from the competition because of their ability to handle materials that are viscous and abrasive. They are widely applied in oil and gas, chemical processing and wastewater treatment. The versatility of these pumps allows them to pump sludges, slurries and other difficult pumping fluids with efficiency even under high pressure.
SPX Performance: On the other hand, SPX lobe pumps are well known for the ability to crush salad products during pumping thus making it suitable for product sensitive areas like dairy, food and cosmetics. SPX pumps are made with less shear for perturbable products. Their types are also clean in place compatible, which is important since a lot of attention is paid to hygiene.
Applications
Also though NETZSCH and SPX lobe pumps are interchangeable, each has a particular strength.
NETZSCH Applications: It is magnesium lobe pump which is used in sectors like petrochemical, oil & gas and environmental thick fluids’ treatment, such as sludge or slurry. These pumps are capable of handling high solids concentration and are built for wear resistance.
SPX Applications / Uses: SPX pumps are used in industries where strict sanitary conditions are required such as food and beverage, pharmaceutical and personal care industries. The construction protects the pumped fluid, which is vital for applying the equipment on products for consumption or medicine.
Maintenance and Serviceability
When picking a lobe pump, maintenance considerations are important and both NETZSCH and SPX have workable answers to this concern.
Maintenance In NETZSCH: The user-friendly approach in NETZSCH pumps makes them easy to disentangle for maintenance purposes. Maintenance of their pumps is cheap and less time-consuming since the modular system of construction enables simple detachment and replacement of non-functioning parts.
SPX Maintenance: SPX also has provided a lobe pump that can be cleaned easily without sacrificing maintenance for efficiency. Their Many CIP and SIP system features facilitate maintenance in sanitary environments. Also, SPX has a lot of support and service which makes it easier for the industry to keep the pumps in good working condition without interfering with the operations of the plants.
Cost-Effectiveness
Both NETZSCH and SPX unique bolt pumps Prices are in the higher range primarily because of the structures and functioning. However, the overall cost of ownership could be different depending on the particular application.
NETZSCH Cost-Effectiveness: NETZSCH pumps are characterized by their long-wearing qualities and an ability to handle high abrasive or highly viscous operations, which when purchased for the first time leads to cost-effectiveness over time because of lower maintenance costs and repair costs. Because they can withstand tough fluids with little erosion, there will be fewer replacements and repairs and this will bring about savings in costs.
SPX Cost-Effectiveness: Unlike other pumps which are competing with SPX Isolators, which are also sold at a high cost, price SPX pumps justify the use of such pumps in most instances where hygiene and product integrity are critical. Their effectiveness in CIP and protection of sensitive products may offer good savings in the long run, addressing mostly those industries where such risks of contamination are high.
Conclusion
Apart from NETZSCH and SPX, lobe pumps of high performance are available from both manufacturers with each having relative merits in relation to industrial needs. If the climatic conditions will involve handling of extremely viscous, dusty slurries, NETZSCH lobe pumps will come out all right in terms of operational efficiency and durability. On the contrary, SPX lobe pumps are the one of the best in the market for dealing with any possible contamination and ensuring gentle handling of the product with its delicate features as well as aggressive cleaning.
When you need to choose one of NETZSCH or SPX, you need to consider the requirements of the application, hence it is important to know the requirements of the operation to select the right application.
