1. Reinforced PVC Fabric
Define the coated-fabric construction, target thickness / weight direction, color, UV exposure, temperature range and any required water-contact documentation.
Source flexible PVC water tanks and water bladders in bulk with custom capacity, welded construction, inlet/outlet configuration, color, logo, accessories and export packing.
DERFLEX supports importers, distributors, contractors, agriculture programs, construction projects, emergency-water programs and private-label buyers that need repeatable specifications—not a one-off generic water bag.
A wholesale PVC water tank is a flexible liquid-storage tank purchased in commercial quantities for resale, OEM branding or project deployment. For B2B procurement, the tank should be specified as one system: reinforced PVC coated fabric, tank geometry, welded seams, reinforced fittings, valves, accessories, inspection requirements and export packing.
Two 10,000 L PVC water tanks can have very different commercial value if one uses a different coated-fabric construction, seam route, fitting package or reinforcement layout. That is why a reliable wholesale comparison starts with a frozen specification before price comparison.
DERFLEX’s current flexible-water-tank family covers PVC and TPU directions across a broad capacity range. This page is intentionally PVC-first: it is designed for buyers searching for a cost-effective, weldable and scalable flexible water-storage range for wholesale and project supply.
Instead of listing dozens of disconnected sizes, structure the wholesale portfolio by real use case, capacity and fitting package.
Small project supply, mobile washdown, reserve water and light-duty portable storage.
Irrigation, jobsite water, temporary water supply and contractor fleet programs.
Remote sites, emergency reserve, project staging and larger agricultural storage.
Large capacities require closer review of footprint, seams, fittings, ground condition and fill/drain rates.
Capacity ranges are procurement groupings, not fixed catalog limits. Final tank geometry and material are confirmed against the actual project specification.
Price becomes meaningful only after every supplier is quoting the same commercial and technical scope.
Define the coated-fabric construction, target thickness / weight direction, color, UV exposure, temperature range and any required water-contact documentation.
Working capacity, maximum footprint and filled height determine load paths, panel layout, site fit and the practical shape of the bladder.
The welding method must match the PVC material and production equipment. Seam route and workmanship should be treated as part of the pressure envelope.
Specify inlet, outlet, vent, drain, hose size, coupling standard and location. Connection areas often need dedicated reinforcement.
Groundsheet, repair items, spare fittings, storage bag, manual and handling accessories can be standardized by wholesale SKU.
Approve model code, logo, care label, carton or bundle, shipping mark and pallet requirement together with the product specification.
Flexible PVC tanks use a reinforced textile structure rather than a rigid molded shell. The polyester reinforcement carries tensile loads while the PVC coating provides the flexible waterproof barrier and a surface compatible with suitable thermal or high-frequency fabrication routes.
Use this table as an RFQ starting point, then confirm the final values on the quotation and approved technical specification.
| Specification Item | Wholesale Direction | What the Buyer Should Confirm |
|---|---|---|
| Material | Reinforced PVC coated technical textile | Stored water / liquid, temperature, UV exposure, folding cycle and required compliance. |
| Capacity | Existing DERFLEX flexible-tank family reference: approx. 500–500,000 L | Usable capacity plus maximum allowed footprint and filled height. |
| Thickness Direction | Existing tank family reference: approx. 0.75–1.20 mm for selected constructions | Do not select by thickness alone; reinforcement, seam design and capacity matter. |
| Tank Format | Pillow / bladder, rectangular / cube, collapsible or custom project format | Choose around site, transport, fill/drain workflow and whether external support is required. |
| Connections | Custom inlet, outlet, vent, drain and coupling options | Pipe / hose size, thread or coupling type, location, pump interface and reinforcement. |
| Color & Branding | Custom color, logo, model label and private-label packing can be discussed | Pantone direction, print method, artwork, warning labels and model coding. |
| MOQ | Project-dependent rather than one universal number | MOQ changes with size mix, custom material, fittings, logo, packaging and sample route. |
| Inspection | Agreed material / workmanship / fitting / leak-tightness / packing checks | Freeze the acceptance checklist before bulk production. |
Visual content is structured around buyer questions rather than decorative imagery.
The same material family can serve very different projects. Final design should follow the operating environment and stored water requirement.
Temporary irrigation storage, rainwater capture, livestock-support water and seasonal field deployment where empty-state transport matters.
Temporary site water, dust-control reserve, washdown and remote work areas that need storage without installing a permanent rigid tank.
Rapid-deployment water storage for response teams and temporary infrastructure. Required water-contact standards must be identified before approval.
Selected temporary process-water, utility and site-support applications after reviewing liquid compatibility, temperature and operating cycle.
DERFLEX’s advantage in this category is the connection between PVC coated fabric knowledge and finished flexible-product fabrication. For an importer or distributor, that makes material selection, weldability, repeat-order consistency and problem diagnosis easier to discuss than when the seller only resells a finished tank.
Existing DERFLEX water-tank material pages and current flexible-tank pages describe in-house PVC coated fabric capability, welding-oriented fabrication, laboratory testing and OEM / export support. The purchasing benefit is better specification control—not simply a lower headline unit price.
Define coating, reinforcement, thickness direction, surface and weldability around the intended tank.
Panel layout, seam route and fitting reinforcement are reviewed together with geometry.
Color, logo, labels, accessories and export packing can be approved as a repeatable SKU.
Carry the approved specification into later production instead of relying on vague “same as last time” instructions.
A useful wholesale quotation explains the price drivers so buyers can compare equivalent products.
Capacity, filled dimensions, panel count and seam length affect material consumption and fabrication time.
Reinforcement, coating formulation, thickness / weight direction, UV or low-temperature requirement and water-contact documentation can change cost.
Valve quantity, size, material, couplings, vents, drains and reinforcement patches all change the finished assembly.
Logo printing, model labels, manuals, storage bag, individual carton, pallet and shipping marks add commercial scope.
A mixed order of many custom sizes behaves differently from a repeat run of one standardized model. MOQ should be discussed after the SKU list is defined.
Third-party inspection, custom test requirements and market-specific documentation should be included in the RFQ rather than added after quotation.
The best wholesale program standardizes the product and the packaging at the same time.
Capacity, filled dimensions, material reference, connection layout and tank style.
Color, logo position, model code, warning / care labels and language requirements.
Groundsheet, storage bag, repair items, spare fittings, hose adapters or other project accessories.
Inner protection, carton / bundle, pallet requirement, barcode and shipping marks for distribution.
“Good quality” is not an inspection standard. Freeze measurable or visually checkable acceptance points before production.
Confirm the approved PVC fabric construction, appearance and order reference.
Review panel dimensions, seam appearance and repeatability of the selected weld route.
Check valve type, position, attachment and reinforcement at high-stress areas.
Confirm workmanship, dimensions and the agreed leak / tightness inspection method.
Verify labels, accessories, quantity, packing, shipping marks and inspection records.
Use questions that reveal process control, not just sales claims.
Ask for the PVC coated-fabric construction used for your exact tank rather than accepting “heavy duty PVC” as a complete specification.
The supplier should match fabrication method to the material and discuss seam layout, not only finished appearance.
Connection type, position and reinforcement should follow the real hose, pump and drainage workflow.
Distributor programs need stable model codes, approved components, labels and packaging between orders.
Bulk supply includes packaging, shipping marks, documentation and inspection coordination—not only manufacturing.
Drinking-water suitability must be tied to the exact material formulation, fittings and destination-market requirement.
Use the page that best matches the next procurement question.
Short answers for distributors, importers, contractors and project procurement teams.
For B2B procurement, buy from a supplier that can define and control the PVC coated fabric, tank geometry, welded seams, fitting package, OEM branding, inspection and export packing. DERFLEX supports bulk, project and private-label flexible water tank programs for international buyers.
There is no single useful MOQ for every tank size and configuration. MOQ depends on capacity, material construction, fitting set, custom color or logo, packaging, sample requirements and whether the model already exists or requires new development. Confirm MOQ after the SKU specification is defined.
Current DERFLEX flexible-tank references cover approximately 500 L to 500,000 L across the broader PVC / TPU family. The practical capacity of a specific PVC tank depends on geometry, footprint, seam design, fittings, ground conditions and intended operating cycle.
Main price drivers include capacity, geometry, PVC fabric construction, reinforcement, seam length, valves and fittings, accessories, branding, packing, inspection requirements and total quantity. Compare suppliers only after these items are defined on the same RFQ basis.
Yes. OEM and private-label programs can discuss capacity, dimensions, color, logo, model labels, fitting layout, accessory kit, storage bag and export packaging. Repeat orders are more reliable when product and packaging specifications are approved together.
Do not assume potable-water suitability simply because a tank is PVC or waterproof. State the destination market and required water-contact standard so the exact coating formulation, fittings, fabrication route and supporting documentation can be reviewed before approval.
Many flexible PVC bladder and collapsible tank designs can be folded when empty, which reduces storage and return-shipping volume. The expected folding frequency, temperature and handling method should be included in the material and tank selection process.
Include capacity by model, stored water / liquid, maximum footprint, inlet/outlet sizes, quantity, color, logo, accessories, packing, destination and required documentation. DERFLEX can then review the PVC material direction and quote a repeatable commercial specification.
