FLOPAM FO 4000 MPM Equivalent — Cationic PAM Powder Screening for FO 4650 MPM and FO 4800 MPM
ChinaPAM supplies cationic polyacrylamide powder for FLOPAM FO 4000 MPM requirements. Send the exact grade with its MPM suffix, quantity and destination and we will name the ChinaPAM screening grade, quote current pricing and plan an evaluation. The two MPM grades differ sharply in bulk density, so feeder calibration is part of the changeover plan.

The two MPM grades share molecular weight and preparation, and differ in charge and bulk density. That is why they get different ChinaPAM routes and different feeder settings. SNF and ChinaPAM use separate qualitative bands that do not convert numerically.
| Exact SNF grade | SNF charge / MW | Brookfield cps at 5 / 2.5 / 1 g/L | Bulk density | ChinaPAM route |
|---|---|---|---|---|
| FO 4650 MPM | High / Medium | 350 / 160 / 70 | 0.85 | C8002, C8025 |
| FO 4800 MPM | Very High / Medium | 480 / 300 / 120 | 0.63 | Trial: C8002, C8025 against C8055, C8006 |
Three MPM Facts Buyers Can Trace
Identity: SNF heads the table as cationic polyacrylamide powder of medium molecular weight, with FO 4650 MPM labelled High charge and FO 4800 MPM Very High charge.
Preparation: both columns list 5 g/L recommended and 10 g/L maximum make-up, 45 minutes dissolution and 1 day solution stability. SNF gives viscosities as average indicative values and notes that a viscosity ten times lower can be used when choosing preparation and dosing equipment.
Handling: the listed bulk densities are 0.85 for FO 4650 MPM and 0.63 for FO 4800 MPM. On a volumetric feeder, the two grades are not interchangeable at one setting.
Two Failure Modes to Check Before Bulk Supply
One is mechanical, the other is a routing error on the enquiry.
| Failure mode | Trigger | Symptom | Check |
|---|---|---|---|
| One volumetric calibration for both grades | A feeder set on FO 4650 MPM is run on FO 4800 MPM, or the reverse | Delivered polymer mass and solution strength drift from the target | Weigh a timed discharge from the feeder and recalibrate by mass for the supplied grade |
| MPM suffix dropped | FO 4650 MPM is quoted or tested as a bare FO or SH grade | The enquiry is answered from a different family with a different preparation profile | Keep the MPM suffix on the enquiry, purchase order and COA request |
Feeder Calibration and Bracketed Evaluation
Measure the bulk density of the ChinaPAM grade on arrival and set the feeder by weighed discharge. Prepare the incumbent and the ChinaPAM grade at the same concentration within 5 to 10 g/L, allow full dissolution and record viscosity.
For FO 4650 MPM, compare the high-charge lane against the incumbent with stepped doses on one sample. For FO 4800 MPM, run both brackets side by side under the same conditions. The lowest stable dose that meets your target selects the grade.
What to Send for a Quotation
The exact grade and quantity are enough to start pricing. These details sharpen the evaluation:
| Input | Why it matters |
|---|---|
| FO 4650 MPM or FO 4800 MPM, from the bag label | Decides between the direct lane and the bracketed trial |
| Feeder type and current setting | Needed to plan the mass recalibration |
| Application, sample type and target result | Defines the pass mark for the stepped comparison |
| Current dose and make-up concentration | Baseline for the side-by-side trial |
| 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 MPM active dose. Recalibrate the feeder by mass for the ChinaPAM grade, prepare it at the same working concentration, and compare stepped doses on the same sample. For FO 4800 MPM, run both brackets before fixing the grade.
Frequently Asked Questions — FLOPAM FO 4000 MPM Equivalent — Cationic PAM Powder Screening for FO 4650 MPM and FO 4800 MPM
Can ChinaPAM supply for a FLOPAM FO 4000 MPM requirement?
Yes, as cationic polyacrylamide powder. Send the exact grade with its MPM suffix, quantity and destination and we will name the screening grade, quote current pricing and arrange an evaluation plan.
Why is FO 4800 MPM handled as a trial rather than a direct lane?
SNF lists FO 4800 MPM as medium molecular weight with Very High charge. ChinaPAM has no cationic row in that exact combination, so the evaluation brackets a high-charge lane against a very-high-charge lane and your sample decides.
Can one feeder setting serve both MPM grades?
No. SNF lists bulk density at 0.85 for FO 4650 MPM and 0.63 for FO 4800 MPM, so the same volume delivers roughly a quarter less mass of FO 4800 MPM. Calibrate the feeder by mass for whichever grade is supplied.
Is FO 4650 MPM the same as FO 4650 or FO 4650 SH?
Do not assume so. The MPM suffix is a separate SNF table at medium molecular weight. Quote and test against the grade with its suffix.
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.
