What SNF Publishes for AN 923 SH
The figures below are reproduced from the SNF SAS powder catalogue, Catalogue 2007 Poudres, page 35, covering the FLOPAM AN 900 SH series. The catalogue prints its own caveat: the data are given for information only and do not constitute a specification.
AN 923 SH sits at medium charge density in the SH table. SNF publishes Brookfield readings of approximately 1600 cps at 5.0 g/l, 600 cps at 2.5 g/l, and 200 cps at 1.0 g/l (approximate values, SNF Catalogue 2007 Poudres p.35). Recommended make-up concentration is 3 g/l; maximum is 5 g/l; dissolution time is 60 minutes in deionized water at 5 g/L and 25°C.
The SHU variant of AN 923 also appears on page 35 with a different profile: approximately 1320 cps at 5.0 g/l, 680 cps at 2.5 g/l, and 320 cps at 1.0 g/l. Against the SH row the ordering changes with concentration: SHU is lower than SH at 5.0 g/l and higher at 2.5 g/l and 1.0 g/l. Those are the published reference values at the three concentrations the table prints; the catalogue gives no figures between or below them. Check which suffix your purchase specification names, and compare the two on your own water at the concentration you actually make up.
Our Supply Route and Selection Logic
Our K62 grade sits at High MW and Medium charge on our own internal scale. SNF describes AN 923 SH as Medium charge and Very High MW on its own scale (Catalogue 2007 Poudres p.35). Both charge descriptors read Medium, but each manufacturer sets its own band boundaries, so the two are not numerically equivalent; and the MW descriptors differ outright — our High against SNF's Very High — which is a real difference in how each grade is described, not just a wording difference between scales. A jar test on your feed water at the make-up concentration you intend to run is how that difference gets settled for your process.
The choice between SH and SHU is a purchasing question before it is an operating one: the two suffixes carry different published viscosity rows at the same three concentrations. Confirm the exact suffix on the purchase order, then compare the candidate supply against your incumbent on the same feed water and at the same make-up concentration before committing to volume. For AN 923 VHM duty, see the AN 923 VHM equivalent page — that grade is at ultra high molecular weight with different published values.
Dosage Guide
SNF publishes AN 923 SH at 3 g/l recommended and 5 g/l maximum make-up concentration, with 60 minutes dissolution at 5 g/l and 25°C (Catalogue 2007 Poudres, page 35). Our preparation parameters for the supply grade are 1–3 g/L recommended and max 5 g/L, dissolution ≤60 min at working concentration. Establish the effective dose on your water by jar test before operating at volume.
Frequently Asked Questions — FLOPAM AN 923 SH Equivalent — Medium Charge Very High MW Anionic PAM
Do you have a supply route for FLOPAM AN 923 SH duty?
Yes. ChinaPAM supplies a medium-charge, high-molecular-weight anionic PAM powder route for AN 923 SH duty. Contact us to discuss pricing, sample arrangements and applicable product documents.
What is the difference between FLOPAM AN 923 SH and AN 923 SHU?
Both grades carry medium charge density. The difference is viscosity profile. AN 923 SH (Catalogue 2007 p.35) publishes Brookfield 1600/600/200 cps at 5/2.5/1 g/l. AN 923 SHU, also on page 35, publishes 1320/680/320 cps at the same three concentrations. The ordering reverses at 2.5 g/l and 1.0 g/l: SHU is higher at dilute concentrations, SH is higher at 5.0 g/l. Check the full suffix on your purchase order before selecting a supply route.
What make-up concentration does SNF publish for AN 923 SH?
SNF publishes 3 g/l recommended and 5 g/l maximum for AN 923 SH (Catalogue 2007 Poudres, page 35). Our preparation parameters for the supply grade are 1–3 g/L recommended and max 5 g/L.
How do I verify whether an alternative anionic PAM supply works for my process?
Prepare polymer solution at 1–3 g/L and run a jar test or settling test on your actual feed water at several dose rates.
Does this page apply if my bags say AN 923 SHU or AN 923 VHM?
No. This page covers the AN 923 SH suffix only, using data from Catalogue 2007 Poudres page 35. For AN 923 VHM, see the AN 923 VHM equivalent page. AN 923 SHU has a different viscosity profile and is a distinct grade.
