Prebur WaterTech — Water Filtration Sourcing Brief

Momo Global (Pty) Ltd sourcing project · Prepared for Tracy Chow, Nana Zhou & Mario Nell, East 2 West · August 2026
Channel: Prebur ecommerce + contractor counter sales (Silverton warehouse, Pretoria) + installer network (Centurion)
Rev 3 — 14 August 2026: Exact Model Codes for Quotation added at the end — the specific factory model numbers to quote against, per factory, plus Order 1 components and a Phase 2 list for indicative pricing.
Rev 2 — 7 August 2026: specs revised after verification against the SA installed base (pressure, o-rings, inline threads — marked "Rev 2" below), and Catalogue Review & Feedback added covering Factories 01–07.

Project Summary

What we are building: a water filtration line sold under the Prebur brand ("Prebur WaterTech"), following the same model as our air filter programme: OEM manufacture in China, Prebur-branded packaging, imported by Momo Global via Pro Logistics.

The launch line is deliberately tight: 17 SKUs, every one already selling in volume in South Africa today. No experimental products in Order 1. Systems build the customer base; replacement cartridges are the repeat-revenue core — cartridge pricing and consistency matter more than system pricing.

What we need from E2W now: identify 1–2 integrated factories and return FOB quotations against the SKU tables below. First order is a 20ft container (~31 CBM), indicative FOB value US$25,000–30,000 (final mix re-balanced once real FOB prices are in). A short Phase 2 list at the end shows where the programme goes next — for factory-capability awareness only, no quotes needed yet.

Target factory profile

Critical South African requirements (apply to every SKU)

Launch Line — 17 SKUs for Quotation

Quantities are indicative for quotation and container planning — final PO quantities will be balanced to the 20ft after FOB confirmation. "SA proof of demand" shows why each SKU made the launch list.

Quotation Format Requested

Per SKU please provide, in the usual E2W quote sheet format:

Catalogue Review & Feedback — Factories 01–07 (added 7 August 2026)

All seven catalogues received via E2W (6–7 August) were reviewed in full against the 17-SKU launch line, augmented with each factory's website and storefronts. The Rev 2 spec changes above came out of the same exercise — we verified every critical spec against the SA installed base (Pentair/Pentek benchmarks, Puritech, SUPERPURE, H2O Warehouse) at the same time.

Exact Model Codes for Quotation — per factory (added 14 August 2026)

To remove any ambiguity from the RFQ, we have gone through the factory catalogues and identified the specific model codes that correspond to each of our 17 SKUs. Please quote against these codes rather than against descriptions.

Priority: Factory 01 — Yuyao Yadong / Ningbo Keman. They matched 14 of our 17 SKUs, the best coverage of any factory in the pack, and their catalogue prints model codes for every one. The table below is taken directly from their 2025–2026 Product manual with the catalogue page number against each entry. This is the quotation we most need.

⚠️ Electrical compliance — important, and it affects only A2. South Africa requires an NRCS Letter of Authority before an electrical appliance can be imported or sold, under compulsory specification VC 8055 (based on the SANS/IEC 60335 series), which covers both the appliance and its transformer / power supply. Please tell us, with your quote:

Phase 2 — indicative pricing only, no commitment (Factory 01)

These are the categories we expect to add in later orders. We are not ordering them now — but since your catalogue covers most of them, indicative FOB prices and MOQs at this stage would help us plan, and would save a second round of quoting later. Rough numbers are fine.

On Phase 2 we only need indicative FOB and MOQ at this stage — no need for carton data or lead times until we commit. If any category is a poor fit for your factory, please say so; we would rather know now.

Factories 02, 05, 06, 08 — model codes not printed

The catalogues from Jinan Baina (F02), Dongguan Beyclean (F05) and Bishuikang (F06) are image-only and carry no printed model numbers we can quote against. Ningbo Dukang (F08) quoted against our own SKU codes without returning their factory model numbers.

For these four, please ask each factory to quote against our SKU codes below and to return their own model number for each line, so we can build the same kind of reference table:

FactorySKUs to quoteNotes for the factory
F02 — Jinan BainaC1–C7 cartridges, D1, D2 housingsReturn model number per line. Also required: ISO 9001:2015 certificate (brochure shows the withdrawn 2008 version) and housing working/burst pressure data (catalogue prints 0.4 MPa working — we need ≥6.2 bar evidence or an explanation of the rating convention).
F05 — Dongguan BeycleanB1 (200 units + 200 refill sets)
B2 (400 units + refills)
Return model number and the refill cartridge code per unit — the refill format locks the customer in, so we need it named. On B2, confirm against our spec (15/20-stage, KDF-55 / calcium sulfite / vitamin-C media, ½" BSP) or propose the nearest equivalent with the full media list.
F06 — BishuikangC1–C7 cartridges, D1, D2 housingsReturn model number per line. Also required: current ISO 9001 certificate (the one shown expired September 2024); on C5 quote genuine Vontron fitted, or supply independent rejection-rate test data for their own "HSD" membrane.
F08 — Ningbo DukangC1–C7 cartridges, B3 gravity potTheir quotation of 12 August did not include factory model numbers, carton gross weights or cartons-per-quantity, and the MOQ / 2× / 5× price columns were identical on every line — please ask for these to be completed. Also: why was C7 (20" Big Blue PP) not quoted, when the 10" equivalents were?

Interchangeability — the dimension that matters most

Our replacement cartridges must drop into filter housings already installed in South African homes (Pentair/Pentek, Puritech, JoJo, SUPERPURE). That makes the cartridge outer diameter the single most important dimension in this whole quotation — more important than price.

We will verify these dimensions physically against locally-stocked housings when samples arrive.

What every quotation must contain

Three items were missing from the first quotation we received, and their absence made the container impossible to plan. Please make sure every factory returns all of them:

  1. Genuine price breaks. FOB at our indicated quantity, then real, different prices at MOQ / 2× MOQ / 5× MOQ.
  2. Carton gross weight and cartons per quantity, not just carton dimensions — we cannot calculate a container without weights.
  3. MOQ per SKU stated against our quantity, with any line where the MOQ exceeds our requested quantity flagged in the quote itself.
