Bulk Tank to Filling Machine: A Buyer’s Supply Checklist
You have a mixing tank or bulk container. The new filling machine has a product inlet. Before ordering, agree exactly what connects the two—and who is responsible for making that connection work.
This guide is available in English. Other language options open site homepages, not translations of this article.
Short answer: Do not approve a filler on the dosing unit alone. Request a marked tank-to-filler drawing, an included-and-excluded equipment list, written inlet requirements and a test plan that represents your production supply. A transfer pump, receiving hopper or buffer tank should be treated as a proposed project component, not assumed to be included.
Start with the handover point, not a pump model
Ask the supplier to mark where its responsibility starts: the bulk-container outlet, a transfer-pump discharge, a receiving tank or the filler inlet. Have the buyer’s existing equipment marked separately. The useful outcome is one agreed drawing with named connection points—not two quotations that each leave the connecting section to somebody else.
Keep this decision separate from choosing the dosing method. ZXSMART publishes a servo piston filling machine for liquids, creams, gels and pastes, subject to product and configuration checks. That product listing does not establish that every existing tank, transfer pump or IBC connection is compatible.
Send a supply brief with the quotation request
Give the supplier enough information to review the real connection. If a detail is unknown, mark it as requiring confirmation rather than filling in an assumed value.
| Buyer information | What to send or ask for |
|---|---|
| Product condition | Product identity, approved temperature range, available viscosity information, and whether normal handling introduces foam or requires mixing. |
| Existing vessel | Tank or container identification, outlet details, available drawings, normal operating conditions and applicable equipment limits. |
| Physical route | A layout sketch showing the tank, filler, outlet and inlet heights, proposed hose route, connections and access for cleaning. |
| Equipment already installed | Transfer pump, valves, filters, receiving vessel and controls; identify their owners and available documentation. |
| Production routine | Batch size, target filling task, how the source is replenished or changed, planned stops, cleaning and product changes. |
For product-method selection, use the existing cream and gel filling guide. Here, the purchasing question is narrower: which supply conditions and equipment are included in the proposed system?
Turn “suitable product supply” into a written scope
Ask the supplier to state the required conditions at the marked handover point, including any permitted pressure range, supply requirements and relevant operating limitations. Ask which values depend on the product, which need a trial, and who is responsible for confirming them.
Do not copy the machine’s compressed-air specification into a product-feed requirement. Request separate confirmation for these two interfaces. If the proposed supply involves a different tank arrangement, heating, agitation or pressure, have the responsible qualified team approve that arrangement before changing the process. This checklist is not a vessel-modification or pump-sizing instruction.
| Quotation item | Require one explicit status | Record the responsible party |
|---|---|---|
| Transfer pump or unloading equipment | Included / optional / buyer-supplied / excluded | Selection, supply and verification |
| Receiving hopper or buffer tank | Included / optional / not required subject to confirmation | Design and operating limits |
| Hoses, fittings, seals and valves | Itemized scope and connection details | Material approval and installation |
| Supply controls and stop/restart behavior | Agreed functions and interfaces | Integration and testing |
| Cleaning and residual product | Defined product-contact boundary | Procedure approval and verification |
A blank status is an open commercial question. Resolve it before comparing the total price; do not quietly treat an unpriced component as included.
Test the proposed connection, not an easier substitute
Ask what supply arrangement will be used during the factory trial. If the factory uses a nearby hopper while your site uses an existing remote tank, record that difference. A demonstration still has value, but it should not be described as proof of an untested site connection.
Agree which normal production states the trial should represent: initial supply, sustained filling, the source’s agreed low operating level, replenishment or container change, a planned stop and restart, and product changeover where applicable. Have the supplier identify which states can be demonstrated at the factory and which remain site-acceptance items.
Use the existing filling accuracy guide to agree quantity measurement and acceptance criteria. This article adds the supply-state record; it does not prescribe a universal tolerance, test duration or sample quantity.
Keep a short exception list for site acceptance
Before shipment, list every supply-related item not demonstrated: the buyer’s tank, actual route, transfer equipment, control interface or production product. Give each item an owner, required evidence and an agreed point for resolution. “To be confirmed at site” is useful only when everybody knows what remains unconfirmed.
Carry that list into the installation and commissioning checklist. Include the entire agreed supply path in the cleaning and changeover review; do not stop the responsibility list at the most convenient connection.
A paragraph you can add to your RFQ
Please identify the proposed product-supply handover point and review our existing bulk container or mixing tank, product and connecting route. Itemize included, optional and buyer-supplied transfer equipment, receiving vessels, hoses, fittings and controls. State the required inlet conditions, trial arrangement, exclusions and site checks needed before accepting the complete supply-to-filling system.
Buyer FAQ
Can an existing IBC or mixing tank connect directly to a new filler?
That has to be confirmed for the actual tank, product, connecting path and filler. Request a written interface review; do not assume that a compatible-looking outlet or a successful water demonstration proves compatibility.
Does a filling-machine quotation include the transfer pump?
Not necessarily. Ask the supplier to list the transfer pump, buffer tank, hoses, fittings, controls and installation separately as included, optional, buyer-supplied or excluded.
What product-feed pressure should I specify?
Do not select a universal pressure from an article. Request the permitted conditions at the agreed filler inlet, the relevant product and operating states, and who will verify the supply arrangement.
Can a factory test prove that my existing supply system will work?
Only to the extent that the agreed factory test represents it. Record any substituted tank, hose, pump, product or controls, then list what still needs checking at the buyer’s site.
Should I change the tank pressure if the filler runs slowly?
Do not pressurize a vessel or change its operating conditions without qualified review of the equipment and approved process. First ask the responsible supplier or engineer to assess the complete feed arrangement.
Discuss the supply boundary before approving the filler
Send ZXSMART your product information, tank and outlet details, proposed layout, bottle and dose range, target output, and equipment already available. Ask for a project-specific review and a written statement of what the quotation includes. Do not assume that a particular pump, hopper, vessel modification or direct IBC connection is available until it has been confirmed.

Research and scope
A manufacturing discussion about cream filling from a separate tank describes a semi-automatic filler user’s supply question. It is a problem signal, not a ZXSMART customer case, a verified diagnosis or proof of automatic-machine compatibility. Commenter modification and pressurization suggestions are not adopted here.
The linked ZXSMART pages support the product and review boundaries. The supply brief, responsibility table and RFQ paragraph are suggested buyer records, not a standard equipment package or completed project-specific engineering review.
