What SNF Publishes for AN 913 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. Verify against a current data sheet from SNF or its distributor before use in any contractual context.
AN 913 SH sits in the AN 900 SH & SHU table at low charge density and very high molecular weight. SNF publishes Brookfield readings of approximately 1300 cps at 5.0 g/l, 500 cps at 2.5 g/l, and 150 cps at 1.0 g/l (approximate values, SNF Catalogue 2007 Poudres p.35). Recommended make-up concentration is 5 g/l; maximum is 10 g/l; dissolution time is 60 minutes in deionized water at 5 g/L and 25°C.
The viscosity comparison with AN 913 VHM (Catalogue 2007 p.34, ultra high MW) is instructive. At 5.0 g/l VHM publishes 1500 cps versus SH 1300 cps — VHM is higher. At 2.5 g/l VHM publishes 600 cps versus SH 500 cps — VHM remains higher. At 1.0 g/l the ordering reverses: VHM publishes 140 cps while SH publishes 150 cps. These are the published figures for the two suffix series. Do not transfer the VHM dissolution time of 90 minutes to AN 913 SH, which publishes 60 minutes.
Our Supply Route and Selection Logic
Our 1082 grade sits at very high molecular weight and low charge on our own internal scale. SNF describes AN 913 SH as low charge and very high MW on its own scale (Catalogue 2007 Poudres p.35). The two descriptions read alike, but each manufacturer sets its own band boundaries, so matching descriptors are not a numeric equivalence between the two products. The make-up limits do not carry across either: the 5 g/l recommended and 10 g/l maximum concentrations SNF publishes belong to AN 913 SH, while our supply grade is prepared at 1–3 g/L with a 5 g/L maximum. Contact us to discuss pricing, sample arrangements and applicable product documents.
The practical question for the buyer is whether the SH suffix is the correct suffix for their application. If the bags read VHM, the AN 913 VHM equivalent page is the correct starting point. If the bags read a number in the 900 series without a suffix, the standard grade pages cover that. The SH series occupies the tier between non-suffix and VHM, and the correct selection depends on the actual suffix present in the purchase specification.
Dosage Guide
SNF publishes AN 913 SH at 5 g/l recommended and 10 g/l maximum make-up concentration, with 60 minutes dissolution in deionized water 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 913 SH Equivalent — Low Charge Very High MW Anionic PAM
Do you have a supply route for FLOPAM AN 913 SH duty?
Yes. ChinaPAM supplies a low-charge, very-high-molecular-weight anionic PAM powder route for AN 913 SH duty. Contact us to discuss pricing, sample arrangements and applicable product documents.
What is the difference between FLOPAM AN 913 SH and AN 913 VHM?
Both grades carry low charge density. The difference is in molecular weight tier and viscosity profile. AN 913 VHM (Catalogue 2007 p.34) is at ultra high molecular weight with published Brookfield 1500/600/140 cps at 5/2.5/1 g/l. AN 913 SH (p.35) is at very high molecular weight with 1300/500/150 cps at the same concentrations. The ordering changes at 1.0 g/l: SH 150 cps is higher than VHM 140 cps at that dilution. Check the suffix on your bags — SH and VHM are not interchangeable.
What make-up concentration does SNF publish for AN 913 SH?
SNF publishes 5 g/l recommended and 10 g/l maximum for AN 913 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. Compare settling rate and supernatant clarity against your current AN 913 SH supply at several dose rates.
Does this page apply if my bags say AN 913 with a suffix other than SH?
No. AN 913 appears in the VHM table on page 34 with different properties. This page covers the SH suffix only, using data from Catalogue 2007 Poudres page 35. For AN 913 VHM, see the AN 913 VHM equivalent page.
