Supply Route Comparison
Published reference data and the ChinaPAM route for SNF FLOPAM FO 4000 PWG and SEP grades
Competitor figures are from the archived SNF powder and bead catalogue, table FLOPAM FO 4000 PWG & SEP (PDF page 25). The printed edition year of this archived catalogue is not confirmed. SNF states these data are given for information only and do not constitute a specification. They are historical indicative values under SNF test conditions, not ChinaPAM specifications and not evidence of current SNF availability.

PWG and SEP Selector: Four Base Grades, Eight Columns
Read the base number first; the PWG or SEP suffix does not change the published values. The technical screening start is shown for each base grade and is confirmed only after the document check. SNF and ChinaPAM bands are separate qualitative scales that do not convert numerically.
| Base grade (PWG = SEP) | SNF charge / MW | Brookfield cps at 5 / 2.5 / 1 g/L; density | Rec. / max. g/L; dissolution | Technical screening start |
|---|---|---|---|---|
| FO 4115 | Very Low / High | 120 / 50 / 20; 0.80 | 5 / 10; 120 min | C8008 |
| FO 4140 | Very Low / High | 230 / 100 / 40; 0.80 | 5 / 10; 90 min | C8008 |
| FO 4190 | Low / High | 280 / 130 / 45; 0.80 | 4 / 10; 90 min | C8008 |
| FO 4240 | Low / High | 415 / 180 / 70; 0.85 | 4 / 10; 60 min | C8008 |
Three PWG and SEP Facts Buyers Can Trace
Heading: SNF groups these eight columns under drinking water production, all cationic powder of high molecular weight.
Charge: FO 4115 and FO 4140 are labelled Very Low charge and FO 4190 and FO 4240 Low charge; Brookfield values at 5 g/L rise from 120 cps to 415 cps across the four base grades.
Suffix: within each same-number pair, PWG and SEP carry identical published values, and the catalogue does not define what separates them. SNF gives viscosities as average indicative values and states the data do not constitute a specification.
Two Failure Modes to Check Before Quotation
One is a documentation error, the other a selection error.
| Failure mode | Trigger | Symptom | Check |
|---|---|---|---|
| Suffix read as approval | PWG or SEP is taken as proof that any replacement grade is approved for drinking water | Project documents are missing when the authority or client reviews the supply | List the required documents in the enquiry; they are confirmed before the quotation is finalised |
| Selection from the heading only | A grade is chosen because it sits in the drinking-water table | Charge position and preparation branch differ from the incumbent | Start from the exact base number and its charge, dissolution and make-up values |
Document Check First, Then the Same-Water Trial
Step one is documents: tell us the market, the authority or client specification, and the list of documents the supply must carry. We confirm what can be provided for the screening grade before the quotation is finalised.
Step two is the technical check: prepare the incumbent and the ChinaPAM grade at the same concentration within the window of the exact base grade, record dissolution and viscosity, and compare stepped doses on the same raw water. The lowest stable dose that meets the target selects the grade.
What to Send for a Quotation
The full grade and the document list come first. These details complete the enquiry:
| Input | Why it matters |
|---|---|
| Full grade: FO number with PWG or SEP | Identifies the base grade and charge position |
| Market, authority and project specification | Defines the document check |
| Required document list | Confirmed before the quotation is finalised |
| Raw water type, current dose and target | Sets the same-water trial conditions |
| Expected volume and destination | Pricing, packaging and lead time in the quotation |
Dosage Guide
Settle the document requirement first. Then start from your current PWG or SEP active dose, prepare the ChinaPAM grade at the same working concentration, and compare stepped doses on the same raw water before any supply decision.
Frequently Asked Questions — FLOPAM FO 4000 PWG and SEP Grades — Cationic PAM Selection Route with Document Check
Can ChinaPAM supply for a FLOPAM FO 4000 PWG or SEP requirement?
ChinaPAM runs a cationic polyacrylamide selection route for these enquiries: we identify the base grade, name a screening grade, confirm which documents your project needs and then quote. Send the full grade, the duty and the documents your authority requires.
Does a PWG or SEP suffix mean the ChinaPAM grade is approved for drinking water?
No. The suffix is an SNF catalogue label and is not evidence of any ChinaPAM approval. The documents your market or project requires are confirmed before the quotation is finalised.
What is the difference between FO 4140 SEP and FO 4140 PWG?
The catalogue does not define it. Each same-number pair carries identical published values. Select on base grade and charge, and settle documents as a separate check.
Can I choose from the drinking-water heading alone?
No. The table mixes Very Low charge (FO 4115, 4140) and Low charge (FO 4190, 4240), with dissolution from 120 down to 60 minutes and make-up at 5 or 4 g/L. Start from the exact base number.
Where is the detailed FO 4140 SEP page?
FO 4140 SEP keeps its own exact-model page, linked below. This family page summarises it so the eight PWG and SEP columns can be compared in one place.
