FLOPAM AN 900 HD Series Equivalent — Anionic PAM Powder Screening for AN 905 HD to AN 956 HD
ChinaPAM supplies anionic polyacrylamide powder for FLOPAM AN 900 HD requirements. Send the full HD grade, quantity and destination and we will name the ChinaPAM screening lane, quote current pricing and plan a sample test. Keep the HD suffix on every document: it is a separate SNF table, and a bare-grade viscosity assumption can mis-size your make-up and pumping.

AN 900 HD Grade Selector: Seven Exact Grades, Three ChinaPAM Lanes
Read the exact grade from your bag label or purchase order, then start from the ChinaPAM lane on that row. The lanes are directional screening starts chosen by charge position, not a claim of cross-brand equivalence. SNF and ChinaPAM each use their own qualitative charge and molecular-weight bands, and the two scales do not convert numerically.
| Exact SNF grade | SNF charge | Brookfield cps at 5 / 2.5 / 1 g/L | SNF rec. / max. g/L | ChinaPAM starting lane |
|---|---|---|---|---|
| AN 905 HD | Very Low | 250 / 120 / 50 | 5 / 10 | CNfloc 1042 (1082 for a longer chain) |
| AN 910 HD | Low | 550 / 170 / 70 | 5 / 10 | CNfloc 1042 (1082 for a longer chain) |
| AN 913 HD | Low | 600 / 200 / 80 | 5 / 10 | CNfloc 1042 (1082 for a longer chain) |
| AN 923 HD | Medium | 850 / 350 / 140 | 3 / 5 | CNfloc 1062, 1063 (K62 by application) |
| AN 934 HD | Medium | 1000 / 400 / 140 | 3 / 5 | CNfloc 1062, 1063 (K62 by application) |
| AN 945 HD | High | 1000 / 400 / 140 | 3 / 5 | CNfloc 1054, 1054VK |
| AN 956 HD | High | 950 / 380 / 140 | 3 / 5 | CNfloc 1054, 1054VK |
Three HD Facts Buyers Can Trace
First, identity: SNF 2007 puts the seven exact HD grades in their own p.40 table headed anionic powder of high molecular weight and low viscosity. An HD line on a tender is its own purchasing line, not a spelling of the bare AN 900 grade.
Second, spread: the seven grades run across Very Low, Low, Medium and High charge labels, and their indicative Brookfield values at 5 g/L run from 250 cps for AN 905 HD to 1000 cps for AN 934 HD and AN 945 HD. SNF gives these as average indicative values and notes that a viscosity ten times lower can be used when choosing preparation and dosing equipment.
Third, preparation: all seven columns list 60 minutes dissolution at 5 g/L in deionised water at 25°C. The recommended make-up is 5 g/L for AN 905, 910 and 913 HD and 3 g/L for the four higher-charge grades.
Two Failure Modes Worth Checking Before Bulk Supply
Both start with reading less of the label than is printed on it.
| Failure mode | Trigger | Symptom | Check |
|---|---|---|---|
| HD suffix dropped | The bare standard-grade viscosity table is used for an HD enquiry | Make-up tank, maturation time or pump sizing does not match the solution actually produced | Confirm the full bag-label grade, then measure viscosity at your working concentration before equipment settings are fixed |
| Selection by charge label only | A grade is picked from the charge word while the published HD viscosities differ inside the same table | Unexpected dilution behaviour, pump pressure or settling response after changeover | Confirm the full model and run a same-feed jar test for the shortlisted ChinaPAM grade |
Actual-Feed Jar Test and Viscosity Verification Plan
Keep your current HD grade as the baseline. Prepare it and the shortlisted ChinaPAM grades at the same working concentration, within the make-up window of the exact HD column, and let each hydrate fully. Record dissolution time and solution viscosity before any dosing.
Dose each solution in steps on one representative feed sample with the same mixing energy and solution age. Record settling rate, supernatant clarity and the dose where extra polymer stops helping. The lowest stable dose that meets your target selects the grade; pump and make-up settings are fixed only after the viscosity check agrees.
What to Send for a Quotation
The exact HD grade and quantity are enough to start pricing. These details sharpen the sample plan:
| Input | Why it matters |
|---|---|
| Full grade with HD suffix, or a bag-label photo | Separates HD from bare, SD, SH and MPM grades with the same number |
| Application and feed | Decides which lane is screened first |
| Make-up concentration and preparation equipment | Sets the viscosity and dissolution check conditions |
| 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
Start from your current AN 900 HD active dose. Prepare the shortlisted ChinaPAM powder at the same working concentration as the incumbent, allow full hydration, and compare stepped doses on the same feed. Fix dose and equipment settings only after the viscosity check matches.
Frequently Asked Questions — FLOPAM AN 900 HD Series Equivalent — Anionic PAM Powder Screening for AN 905 HD to AN 956 HD
Can ChinaPAM supply for a FLOPAM AN 900 HD requirement?
Yes. ChinaPAM supplies anionic polyacrylamide powder for AN 900 HD enquiries. Send the full HD grade, quantity and destination and we will name the screening lane, quote current pricing and arrange a sample test plan.
Is AN 934 HD the same polymer as bare AN 934?
Do not assume so. SNF gives the HD grades their own p.40 table headed high molecular weight and low viscosity, separate from the standard AN 900 table. Quote, test and size equipment against the grade with its HD suffix.
AN 934 HD and AN 945 HD both show 1000 cps at 5 g/L. Can they be swapped?
Not on that number alone. They carry different SNF charge labels, Medium and High. Viscosity at one concentration does not tell you how the feed responds, so run the same-feed jar test on the exact grade.
Which make-up concentration should I plan for?
SNF lists 5 g/L recommended and 10 g/L maximum for AN 905, 910 and 913 HD, and 3 g/L and 5 g/L for AN 923 to AN 956 HD. For the ChinaPAM grade, use its TDS and confirm viscosity at your own working concentration.
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.
