Pumps with relatively short shafts—less than 30 to 50 feet—are driven by solid shaft drivers. As a result, practically all process pumps and circulators are powered by them. Because the pumps employ mechanical seals rather than packing, they offer more positive shaft alignment, which is crucial.
Nevertheless, when a solid shaft driver is employed, the height of the adjustable plate in the three- or four-piece coupling restricts the axial adjustment of the pump rotor. The largest axial adjustment is typically between 12 and 34 in. Typically, thrust bearings may support either upthrust or downthrust.
The Global Solid-Shaft Motor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Simotics Vertical Solid Shaft NEMA Premium motors with high thrust have been released by Siemens Process Industries and Drives. The high-thrust HP100 and extra-high-thrust LP100 motors meet criteria for efficiency, dependability, durability, and adaptability.
Both the HP100 and LP100 have thrust capacities that are higher than the industry average, and the new LP100’s one-year thrust capacity is higher than that of the majority of motors used in the sector. The non-drive end of the motor contains the angular contact thrust bearings, where they are best cooled by the motor fan.
This design makes it simpler for users to re-grease or even replace these bearings. Reduced motor maintenance costs and downtime result from this. Application of the API 610 standard is frequently necessary for the oil, gas, and petrochemical sectors.
When it comes to low vibration, dimensions and tolerances, thrust bearing type and placement, combined thrust capacity and bearing life at 25,000 hours of continuous operation, Siemens VSS motors go above and above the API 610 standard’s “intent,” which some motor manufacturers claim to meet. The option of building to API 610 standards is available to decrease costs.
Moreover, the motors may optionally comply with all applicable IEEE 841 criteria. There is also a non-reverse ratchet choice. The new motor series has a long lifespan and is simple to operate thanks to its all-cast iron structure, oversized terminal box, bolted lifting eyes, corrosion-resistant hardware, and epoxy coating.
They are therefore perfect for demanding applications including in-line pumps, booster pumps, non-clog centrifugal pumps, vertical turbine pumps, mix flow pumps, and propeller pumps. The motors are manufactured and intended to withstand the hardest environments in sectors including petrochemical, pulp and paper, water and waste-water treatment, oil and gas, and water and gas.
