ISO 5199 / ISO 2858 Process Pumps

The ISO Range

Choose by Duty

Series-level figures bound the envelope; the duty point of the specific size governs the selection.

What ISO 5199 Specifies

ISO 5199 is the international technical specification for Class II centrifugal pumps — single-stage or multistage, horizontal or vertical, with any drive, for general application. Chemical process pumps conforming to ISO 2858 are named as typical of the pumps it covers. It belongs to a set of three classes: Class I carries the most severe requirements and Class III the least severe. The current edition is ISO 5199:2002, confirmed in 2018.

ISO 5199 sets requirements, not dimensions. Principal dimensions, designation and nominal duty point come from ISO 2858 (EN 22858), so the two are read together — see ANSI, ISO and API standards compared.

Key technical requirements

• Shaft deflection at the seal faces, under radial load within the allowable operating range: no more than 0.05 mm (50 µm).
• Rolling-bearing basic rating life L10: at least 17,500 hours.
• First lateral critical speed: at least 10% above the maximum allowable continuous speed.
• Vibration on test for horizontal pumps on rigid support, measured at the bearing housing: 3.0 mm/s r.m.s. for shaft centre heights up to 225 mm, 4.5 mm/s above.
• Pressure basis for ISO 2858 pumps: at least 16 bar gauge at 20 °C in cast iron, ductile iron, carbon steel or stainless steel.
• Hydrostatic test at 150% of maximum allowable working pressure for 10 minutes; minimum corrosion allowance 3 mm.
• Seal and packing cavity dimensions are referenced to ISO 3069.

The standard lets a supplier offer pumps that deviate from a clause, provided every deviation is stated. YSM’s AC single stage range is designed to EN ISO 5199 and complies with EN 22858 (ISO 2858).

Replacing Installed European-Pattern Pumps

The AC range is manufactured to the EN ISO 5199 / EN 22858 (ISO 2858) pattern and is offered as a non-OEM replacement for installed European-pattern process pumps of this standard, including common Sulzer-type installations; the DW, DN, KZ, KM and KVT ranges are offered as non-OEM alternatives for equivalent Sulzer-type installations. In every case, interchangeability and interface dimensions are confirmed against the installed pump’s documentation during the selection review — nothing is promised from a family name. Start from the range page that matches the installed pump, or send the nameplate with the duty as run today. Running ANSI B73.1 equipment instead? Start from the ANSI replacement programme.

Where They Run

Pulp & Paper

Pumps in the production of pulp and paper products are subject to extreme conditions of operation. YSM’s extensive knowledge and competitiveness make it the ideal partner of the pulp and paper producers, machinery suppliers and engineering companies.

Food

Food and beverage production relies on our pumping and mixing solutions. Special pumps and agitators have been developed for sugar, starch, and sweeteners. Separation equipment is often used in beverage manufacturing and our process technologies support purification and concentration.

Water and Wastewater

We offer a broad range of pumps and related equipment for water production and transportation as well as wastewater collection and treatment for municipalities and industries. Our expertise also includes separation technologies, and services on rotating equipment.

Oil and Gas Downstream

YSM understands the many processes used in the oil and gas downstream processing industry. We provide state-of-the-art pumping solutions for synfuels, refining, gas processing, petrochemical industry and nitrogenous fertilizers.

Chemical Process Industry

Improves quality, capacity, and energy efficiency with its advanced technologies and services for separation processes; including distillation, absorption, evaporation, extraction and crystallization. Our pumps cover the specific requirements in chemical processes.

Metal

Understanding the application, the corrosive and abrasive characteristics of the fluid, and the flow demands combined with our leading material technology ensure an optimal solution for each plant. Long experience and applications knowledge make YSM a reliable pump supplier.

Application guides for specific duties are collected under Applications.

Design & Engineering Capability

Draw upon YSM Pumps’ experience using sophisticated design tools and testing to save you money, time and energy.

3D Model Tools & Advantages

Industry 3D software is standard on every pump design. Every drawing utilizes a parametric design approach for more effective data mapping and visualization. 3D models can be scaled up with 100% accuracy from model pump to customer pump.

Pattern Validation

3D models have proven the accuracy of the hydraulics and component profile. Test results in the lab are reliable and projectable to field conditions.

Computational Fluid Dynamics (CFD)

YSM Pumps analyzes fluid flow through the internal pump passages to optimize pump performance and reliability. YSM Pumps’ expertise in computational fluid dynamics enables us to provide customers with a high level of pump testing and engineering analysis.

Wet-end castings run through YSM’s own foundry routes — sand, lost-foam and V-process — with traceable inspection reports; the material grade is confirmed to the liquid at selection.
