FLOPAM AN 900 MPM and MPMU Equivalent — Medium-MW Anionic PAM Powder Screening for Six Exact Grades
ChinaPAM supplies anionic polyacrylamide powder for FLOPAM AN 900 MPM and MPMU requirements. Tell us whether your label reads MPM or MPMU, plus quantity and destination, and we will name the ChinaPAM screening lane, quote current pricing and plan a sample test. MPM and MPMU are listed as different columns by SNF, so we quote and test them as different lines.
Supply Route Comparison
Published reference data and the ChinaPAM route for SNF FLOPAM AN 900 MPM / MPMU grades
Competitor figures are from SNF, FLOPAM Catalogue 2007, table FLOPAM AN 900 MPM / MPMU (PDF page 41). SNF states these data are given for information only and do not constitute a specification.

MPM Against MPMU: Where the Pairs Differ
Only AN 923 and AN 934 appear in both suffixes. Read across each pair before deciding whether one ChinaPAM grade can serve both lines on your site. The ChinaPAM lane is a directional screening start, not a claim of cross-brand equivalence; SNF’s Medium molecular-weight tier has no numeric counterpart on the ChinaPAM grade scale.
| Exact SNF grade | SNF charge | Brookfield cps at 5 / 2.5 / 1 g/L | SNF rec. / max. g/L | ChinaPAM starting lane |
|---|---|---|---|---|
| AN 905 MPM | Very Low | 350 / 150 / 50 | 10 / 15 | CNfloc 1042 |
| AN 913 MPM | Low | 800 / 300 / 100 | 8 / 10 | CNfloc 1042 (K42 by application) |
| AN 923 MPM | Medium | 1250 / 450 / 170 | 8 / 10 | CNfloc 1062, K42 (1063 by application) |
| AN 923 MPMU | Medium | 1320 / 520 / 220 | 8 / 10 | CNfloc 1062, K42 (1063 by application) |
| AN 934 MPM | Medium | 1400 / 500 / 170 | 8 / 10 | CNfloc 1062, K42 (1063 by application) |
| AN 934 MPMU | Medium | 1260 / 475 / 195 | 8 / 10 | CNfloc 1062, K42 (1063 by application) |
Three MPM and MPMU Facts Buyers Can Trace
First, identity: SNF 2007 p.41 describes all six grades as anionic powder of medium molecular weight, a separate table from the standard, HD, SD and low-MW BPM grades that share the same numbers.
Second, the suffix matters: AN 923 and AN 934 each have an MPM and an MPMU column with different indicative Brookfield values under the same catalogue conditions, even though charge and MW labels are identical.
Third, preparation: all six columns list 60 minutes dissolution at 5 g/L in deionised water at 25°C. The recommended concentration is 10 g/L for AN 905 MPM and 8 g/L for the other five.
Two Failure Modes Worth Checking Before Bulk Supply
Both come from treating the number as the grade.
| Failure mode | Trigger | Symptom | Check |
|---|---|---|---|
| MPM and MPMU collapsed into one grade | One replacement is qualified for AN 923 or AN 934 without saying which suffix was tested | Solution viscosity differs from the line it replaces although charge and MW labels match | Keep MPM and MPMU as separate order lines and measure viscosity for each at the same working concentration |
| Suffix dropped from the enquiry | Only “AN 923” or “AN 934” is sent | The enquiry is matched to a standard, HD, BPM or other table with a different preparation window | Send the bag label or full grade and confirm the 8 to 10 g/L make-up window before sizing equipment |
Same-Concentration Viscosity and Jar-Test Plan
Prepare the incumbent MPM or MPMU grade and the shortlisted ChinaPAM grades at the same concentration inside the incumbent’s make-up window, and let each hydrate fully. Record dissolution time and solution viscosity. If you run both MPM and MPMU on site, test each against its own incumbent rather than one against the other.
Then dose each solution in steps on one representative feed with the same mixing and observation time. Record the result that matters to your process and the dose where more polymer stops helping. The lowest stable dose that meets the target selects the grade.
What to Send for a Quotation
The exact grade with its suffix and the quantity are enough to start pricing. These details sharpen the sample plan:
| Input | Why it matters |
|---|---|
| Full grade, MPM or MPMU, or a bag-label photo | Separates the two suffixes and the other AN 923 / AN 934 tables |
| Whether both MPM and MPMU are in use on site | Decides whether one or two ChinaPAM lines are screened |
| Make-up concentration and preparation equipment | Sets the viscosity check inside the 8 to 10 g/L window |
| Application, current dose and target result | Baseline and pass mark for the stepped comparison |
| Expected volume and destination | Pricing, packaging and lead time in the quotation |
Documents and Delivery
The applicable TDS is confirmed together with the selected ChinaPAM grade, and a batch COA is tied to the confirmed shipment. Packaging and lead time are confirmed in the quotation for your volume and destination.
Dosage Guide
Use the current MPM or MPMU active dose as the reference. Prepare the shortlisted ChinaPAM powder at the same concentration as the incumbent, within the SNF make-up window for that column, and compare stepped doses on the same feed.
Frequently Asked Questions — FLOPAM AN 900 MPM and MPMU Equivalent — Medium-MW Anionic PAM Powder Screening for Six Exact Grades
Can ChinaPAM supply for a FLOPAM MPM or MPMU requirement?
Yes. ChinaPAM supplies anionic polyacrylamide powder for these enquiries. Send the exact grade with its MPM or MPMU suffix, quantity and destination, and we will name the screening lane, quote current pricing and arrange a sample test plan.
Is AN 923 MPMU the same as AN 923 MPM?
Not by SNF’s own table. The two columns share the Medium charge and Medium MW labels, yet list 1320 / 520 / 220 cps for MPMU against 1250 / 450 / 170 cps for MPM at 5 / 2.5 / 1 g/L. Keep the suffix on the order.
Does MPMU always run higher viscosity than MPM?
No. For AN 934 the order reverses at 5 g/L: 1260 cps for MPMU against 1400 cps for MPM, while MPMU is higher at 1 g/L. There is no rule to apply across the pair, so check the exact column and measure at your concentration.
Why is the make-up concentration higher than for other AN grades?
SNF lists 8 g/L recommended and 10 g/L maximum for five of the six columns, and 10 / 15 g/L for AN 905 MPM. If your equipment was sized for another suffix, confirm the ChinaPAM grade viscosity at your intended concentration before changeover.
Which documents come with the supply?
The TDS for the selected ChinaPAM grade is confirmed with the grade, and a batch COA is tied to the confirmed shipment. Packaging and lead time are set in the quotation.
