Industrial Process Pumps — ANSI, ISO and Heavy-Duty Ranges
YSM Pumps (Jinan Yingsiman Machinery Co., Ltd.) manufactures centrifugal process pumps and replacement parts for the chemical, petrochemical, pulp and paper, water and general process industries. The range is organised in four groups: ANSI/ASME B73.1 chemical process pumps in the Goulds 3196 and Durco Mark 3 patterns, non-OEM replacement pumps and parts for other ANSI B73.1 pumps, EN ISO 5199 / ISO 2858 process pumps with API 610 and vertical-turbine designs, and heavy-duty paper stock pumps.
All pumps and parts are non-OEM, produced to YSM’s own drawings and patterns in our own foundry and machine shop, with every impeller balanced and every casing pressure-tested.

Standards and interchangeability
- ANSI/ASME B73.1 fixes the mounting, flange and shaft dimensions of horizontal end-suction chemical process pumps by size. G196 and D Mark III pumps of the same size and frame or group fit where a 3196-pattern or Mark 3-pattern pump was installed, and the replacement programme extends the same principle to other B73.1 pumps.
Materials of construction
ANSI wet ends are cast in WCB carbon steel, CF8M (316 stainless steel), CD4MCu duplex stainless steel, CN7M (Alloy 20), Monel, Nickel, Hastelloy B and Hastelloy C, Titanium and Zirconium alloy; exotic alloys use the same patterns as the stainless grades and keep the same dimensions and interchangeability. ISO range materials are confirmed per series with the selection. Material certificates and test reports are issued with the order on request.
Manufacturing and quality
Casting (sand, lost-foam and V-process), CNC machining, assembly and testing are carried out in YSM’s own facility. Every impeller is dynamically balanced and every casing hydrostatically tested; assembled pumps are performance-tested on request. See the factory review for the equipment list and photographs.

Products FAQ
What is the difference between the ANSI and ISO ranges?
The ANSI range is built to ASME B73.1, the dimensional standard used across North America and in many international plants; the ISO range is built to EN ISO 5199 / ISO 2858, the European envelope, with API 610 and vertical-turbine designs for refinery and intake duties. Parts are not interchangeable between the two standards, so the choice normally follows the installed base or the project specification.
Do you supply complete pumps or parts only?
Both. Complete bare-shaft pumps or baseplate-mounted units with motor, and replacement wet-end and power-end parts for installed pumps of the patterns listed on each page.
Are YSM pumps OEM products?
No. YSM is an independent manufacturer; all pumps and parts are non-OEM, made to YSM’s own drawings and patterns. Manufacturer names and model numbers identify the pattern a pump follows and are used for compatibility reference only.
Which materials are available?
WCB, CF8M (316SS), CD4MCu, CN7M (Alloy 20), Monel, Nickel, Hastelloy B and C, Titanium and Zirconium alloy for ANSI wet ends; ISO range materials are confirmed per series with the selection.
How do I get a selection or a quotation?
Send the duty point, liquid data and suction conditions — and for a replacement, the nameplate of the installed pump — through the contact form. We reply with a reviewed selection, materials, seal arrangement and a quotation.
All manufacturer names, model numbers and trademarks are used for reference and compatibility identification only. YSM Pumps (Jinan Yingsiman Machinery Co., Ltd.) is not affiliated with, sponsored by, or endorsed by any of these manufacturers. All pumps and parts are non-OEM and manufactured by YSM.
Request a pump selection or interchange review
The form below carries the initial request. The selection review uses, where available:
- Duty point: rated flow and total head (state units), plus minimum and maximum flow if the pump will run across a range.
- Liquid: name or composition, concentration, temperature, specific gravity, viscosity, solids content and size, vapour pressure if volatile.
- Suction conditions: NPSH available, suction lift or flooded suction, tank or vessel layout.
- Installed pump data for replacements: nameplate model, size and frame or group, serial number, and a photo of the nameplate; the pump outline or foundation drawing if available.
- Materials, seal type, seal flush plan, motor supply (voltage, frequency, phase) and any documentation you require (material certificates, test reports, drawings).
We reply with a reviewed selection, the size and frame proposed, materials, seal arrangement and a quotation. Where the enquiry is a replacement for an installed pump, we confirm the dimensional interchange from your nameplate and drawing data before order. Drawings and nameplate photos can follow during review.
