FLOPAM AN 913 VHM Equivalent — Low Charge Ultra High MW Anionic PAM
FLOPAM AN 913 VHM is a low charge, ultra high molecular weight anionic powder, one step above AN 910 in charge and published at a meaningfully higher make-up viscosity. ChinaPAM supplies a low-charge, very-high-molecular-weight anionic PAM powder route for this duty. Both AN 913 VHM and the adjacent AN 910 VHM carry the same charge descriptor ("Low") in the SNF table, but their Brookfield readings at 5 g/l differ by 300 cps — a practical difference for make-up equipment sizing. If your bags read AN 905, see the [AN 905 VHM equivalent](/products/brand-equivalents/flopam-an-905-vhm-equivalent) page. If your bags read AN 910, see the [AN 910 equivalent](/products/brand-equivalents/flopam-an-910-equivalent).

What SNF Publishes for AN 913 VHM
The figures below are from SNF SAS Catalogue 2007 Poudres, page 34, covering the FLOPAM AN 900 VHM series. The catalogue states the data are given for information only and do not constitute a specification. Verify against a current data sheet from SNF or its distributor before contractual use.
AN 913 VHM and AN 910 VHM share the Low charge descriptor in the SNF table, but their Brookfield viscosity profiles differ at all three concentration points. AN 913 reads 1500 / 600 / 140 cps at 5.0 / 2.5 / 1.0 g/l; AN 910 reads 1200 / 550 / 170 cps. At 5.0 g/l AN 913 is 300 cps higher — a measurable difference for make-up line pressure and pump sizing. At 1.0 g/l the order reverses: AN 913 is lower at 140 vs AN 910 at 170. The catalogue does not explain this reversal.
Make-up conditions are 3 g/l recommended, 5 g/l maximum, 90 minutes dissolution at 5 g/l and 25°C — the standard values shared by seven of the nine grades in this table. Only AN 905 VHM departs from these conditions with 5 g/l recommended, 10 g/l maximum, and 150 minutes dissolution.

Our Supply Route and How to Confirm Fit
ChinaPAM supplies a low-charge, very-high-molecular-weight anionic PAM powder (CNfloc 1082 band) for AN 913 VHM duty. We do not claim the products are identical or interchangeable without testing.
A jar test on your own feed water at several dose rates is the correct verification step. Compare settling rate and supernatant clarity against your current AN 913 VHM supply. Our preparation conditions are 1–3 g/L recommended, max 5 g/L, dissolution ≤60 min at working concentration.
Request a trial sample with your water quality parameters. We will provide current TDS and MSDS plus batch-specific COA. Once the trial confirms performance, we confirm supply grade and batch availability for production quantities.
Dosage Guide
SNF publishes AN 913 VHM at 3 g/l recommended and 5 g/l maximum make-up concentration, with 90 minutes dissolution at 5 g/l and 25°C (Catalogue 2007 Poudres, page 34). 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 913 VHM Equivalent — Low Charge Ultra High MW Anionic PAM
Do you have a supply route for FLOPAM AN 913 VHM duty?
Yes. ChinaPAM supplies a low-charge, very-high-molecular-weight anionic PAM powder route for AN 913 VHM duty. Confirm fit by jar test on your own water before placing volume orders.
How does AN 913 VHM differ from AN 910 VHM if both are described as "Low" charge?
Both appear in the same Low charge column grouping in the SNF table, but their Brookfield readings differ. AN 913 VHM publishes 1500 / 600 / 140 cps at 5.0 / 2.5 / 1.0 g/l, while AN 910 VHM publishes 1200 / 550 / 170 cps at the same concentrations. The 300 cps difference at 5 g/l affects make-up equipment sizing. The 1.0 g/l reversal — where AN 913 reads lower (140) than AN 910 (170) — is a published difference in the catalogue.
Why does AN 913 read lower viscosity than AN 910 at 1.0 g/l when it reads higher at 5.0 g/l?
The SNF Catalogue 2007 Poudres page 34 publishes both values without explaining the reversal. At 5.0 g/l AN 913 gives 1500 cps and AN 910 gives 1200; at 1.0 g/l AN 913 gives 140 and AN 910 gives 170. If your process operates at dilute concentration, the 1.0 g/l figure is the relevant check.
Is the 90-minute dissolution time for AN 913 the same as for most of the AN 900 VHM table?
Yes. AN 913 VHM shares the 90-minute dissolution time, 3 g/l recommended, and 5 g/l maximum make-up concentration with six other grades in the nine-column table. Only AN 905 VHM is different at 150 minutes and 5 g/l recommended.
Does this page apply if my bags say AN 913 with a suffix other than VHM?
No. AN 913 appears in other SNF suffix series with different properties. The figures on this page are from the VHM table on page 34 of SNF Catalogue 2007 Poudres. Check the full grade string on your bags.
