Industrial Process Pump Portfolio
ANSI/ASME B73.1 Chemical Process Pumps
Explore ANSI B73.1 chemical process pumps, heavy-duty process pumps, self-priming models and replacement-part support. Start with the pump family or duty requirement, then send the operating data for configuration review.
3Process-pump series families
12Product pages — 7 models & 5 replacement programmes
B73.1Standard for the ANSI families
Family positions and counts summarise the published series and model pages. Size-specific limits, materials and sealing are confirmed during engineering review.
Choose an ANSI Pump Family
Compare the verified family position first, then open the series page for sizes, construction information, technical boundaries and the appropriate model page. The family decides more than hydraulics: it fixes the impeller philosophy, the power-end or frame grouping and the replacement-part logic an installation will live with for decades.
ANSI/ASME B73.1 · Reverse Vane
D Mark III Series
Reverse-vane process-pump family with Group 1, 2 and 3 configurations, including general-purpose and low-flow review paths.
Paper Stock · Heavy-Duty Review
G 3175 / 3180 / 3185
Process-pump family positioned for paper-stock and heavy-duty service. Current source data is primarily dimensional.
Choose by Duty Requirement
Use the operating requirement to narrow the first review. A duty-led start changes the door, not the discipline: final selection still requires the complete flow, head, liquid, suction and construction data.
General purpose
For a broad range of chemical and industrial process duties — the default entry when no dedicated hydraulic constraint applies. Both ANSI families publish a general-purpose model: the G196 general-purpose pump and the D Mark III general-purpose pump.
Low flow
For duty points that would sit far left of best efficiency on a general-purpose size. Both ANSI families carry dedicated low-flow sizes, reached from their series pages. Review low-flow selection →
Self-priming
For applications where suction layout and priming behavior are key selection inputs. Two reviewed models are published: the 3796 self-priming process pump and the unitized self-priming process pump.
Series Comparison
This table identifies the appropriate starting page. It is not a substitute for a reviewed, size-specific pump selection.
| Product family | Standard / position | Impeller / grouping | Best starting point |
|---|---|---|---|
| G196 | ANSI/ASME B73.1 process pump | Open impeller; STX/MTX/LTX/XLTX | Complete pump, wet end or replacement-part review |
| D Mark III | ANSI/ASME B73.1 process pump | Reverse vane; Group 1/2/3 | General-purpose or low-flow selection |
| G 3175/3180/3185 | Paper-stock / heavy-duty process | S/M/L/XL dimensional groups | Large-size and heavy-duty duty review |
Series-level coverage, materials and technical boundaries are stated on each family page.
Materials of Construction
Available wet-end materials may include WCB, CF8M (316 stainless steel), CD4MCu, CN7M / Alloy 20, Monel, Nickel, Hastelloy B or C, Titanium and Zirconium alloy. Availability varies by component, configuration and family. The reason this page maps no liquid names to alloys is that concentration, temperature, impurities and aeration flip the answer — the same acid name can be pumped in steel at one strength and demand an exotic alloy at another. Send the liquid data, not just the liquid name, and prepare the material-selection inputs before the enquiry.
A material name alone is not a compatibility recommendation. Final selection requires liquid composition, concentration, temperature, pressure, solids and corrosion data.
Available Pump Models
Twelve product pages carry the portfolio: general-purpose and low-flow entries for both ANSI families, the heavy-duty G 3175 entry, two self-priming models and five competitor replacement programmes mapped to the G196 family. Each card opens the model page with the published construction data, technical boundaries and the enquiry path; the badge states the position the model is reviewed under.
YSM S series single-stage, double-suction, axially split volute pumps built to GB 5657 and supplied as non-OEM replacement and equivalent pumps for KSB Omega-type installations: DN 80–800, flows to 11,600 m³/h, heads to 200 m, 105 °C, 25 bar, horizontal or vertical arrangement. Interchange is confirmed against the installed pump drawing before order.

ANSI Process Pump FAQ
What information should I send for pump selection?
Send the flow rate, head, liquid name and concentration, temperature, suction condition and any existing pump model or part number. Complete duty data allows our engineers to review and quote without extra follow-up rounds.
Do the published maximums apply to every pump size?
No. Figures shown on series pages are series-level ranges. The limit for each size depends on impeller, speed, material, seal and duty conditions, and is confirmed during engineering review.
Can YSM review an existing pump nameplate or part number?
Yes. Share a photo of the nameplate or the part reference in the enquiry form and our team will identify the pump and respond with a reviewed replacement or spare-parts proposal.
What happens after I submit a request?
An application engineer checks your data, asks for any missing operating details, and returns a written selection and quotation with the applicable technical documents.
Request a Pump Selection
A complete enquiry closes in one review cycle; an incomplete one becomes a correspondence thread. Include the flow, head and suction conditions; the liquid with concentration, temperature and pressure; specific gravity, viscosity and solids; material and seal preferences; and the motor supply, quantity and destination. For an existing installation, add the model, part number, drawing or a nameplate photo — the review then starts from the installed pump rather than from scratch.
Anything unknown can be stated as unknown — a marked gap is reviewable, a silent one is not.

Pump Portfolio Decision Guide
Selection boundaries save both sides a review cycle: the fastest quotation is the one that starts on the right page. The series pages carry the size, construction and boundary detail; the guides carry the duty-led reasoning; the parts center carries the maintenance path. None of them replaces the reviewed, size-specific selection — they decide where the review begins.
Start from a series page when
- The family is already known, or an existing installation points to it.
- Sizes, construction options and replacement-part coverage are the substance of the enquiry.
- You are comparing the G196, D Mark III and heavy-duty family positions directly.
Start from a guide or support page when
- The duty is defined but the family is open — work through the industrial pump applications topics.
- Wetted materials are the open question — prepare the material-selection inputs first.
- The pump already exists and parts are the question — open the replacement parts center with the nameplate data.
