YG Machinery

We recently handled a detailed pre-sale consultation from a buyer in Paraguay, looking for a mini concrete pump for sale. This was not a simple price inquiry. The client sent us a list of 27 technical and commercial questions covering concrete pumping capability, spare parts, warranty, maintenance, and the reliability of our company as a manufacturer. They wanted to understand not only what the machine can do, but also what kind of supplier they would be dealing with over the long term.

The client was comparing our two hot-selling models, the YG-20 and YG-30 mini concrete pumps. Our job was to help them choose the right model based on their site needs and our after-sales capability, without fabricating an order, on-site results, or a “customer satisfaction” statement. In this article, we share our full consultation process, how we positioned our factory attributes and after-sales service, and what still needs written confirmation before the client places an order.

Breakdown of the Client’s 27 Questions (6 Categories)

We grouped the client’s questions into six core topics to reply clearly:

1. Pumping capability: Vertical and horizontal concrete delivery distance, actual output vs. theoretical value, acceptable aggregate size, and concrete mix requirements.
2. Power and operation: Available power supply, starting method, and whether the selected model fits the local site conditions.
3. Core components: Motor/engine brand, hydraulic pump, PLC control, oil system, and main wearing parts.
4. Spare parts & maintenance: Wear parts list, interchangeable spare parts, maintenance cycles, and parts stock for Paraguay.
5. After-sales service: Warranty scope, response time, remote support, and how we handle technical issues after delivery.
6. Factory & company credibility: Whether YG is a real manufacturer, our production capability, export experience, and long-term support commitment.

The client’s biggest concern was not the price tag alone. They wanted to know whether YG-20 or YG-30 would be supported properly for many years of service in Paraguay, and whether we are a professional factory rather than a simple trading company.

How We Answered the Two Hot-Selling Small Concrete Pump Model Question

Both YG-20 and YG-30 are our hot-selling portable mini concrete pumps. We did not push one model over the other without site data. We explained the difference honestly:

• YG-20: A compact model for smaller or medium jobs, easier to transport and position. Suitable for projects with moderate concrete volume and simpler delivery requirements.
• YG-30: A higher-capacity model for larger or continuous pouring work. Better suited when the site requires more output and longer operating hours.

Key point we repeated: the final selection must match the client’s site power supply, concrete mix, daily pouring volume, and delivery distance. Neither model is “always better”. All specific parameters (vertical height, horizontal distance, motor/engine power, output, pipe size) must be confirmed with our technical team for the selected model before ordering.

Electric vs Diesel / Power Concrete Pump Considerations

The Paraguay client raised power supply concerns for their site. We explained that the choice between an electric-powered and a diesel-driven mini concrete pump depends on whether the site has stable grid power.

• If the site has reliable 380V three-phase 50Hz power, an electric model offers lower running costs and cleaner operation.
• If the site is remote or the power supply is unstable, a diesel model works independently of the grid.

We reminded the client that electrical items (motor current, starting mode, circuit breaker, cable size) and the diesel engine configuration must be confirmed with YG for the selected model before ordering. We gave no generic electrical advice that might not apply to Paraguay’s local standards.

After-Sales Service: The Core of This Consultation

The client specifically asked about long-term service, which was the most important part of this consultation. We explained our after-sales approach:

1. Warranty scope: Main components are covered under our standard warranty. Full warranty clauses will be issued as written documents before the order. We did not invent warranty duration or coverage terms.
2. Spare parts support: We can provide a full wear-parts list for one-stop procurement with the main machine. Wear parts include rubber pistons, cutting rings, glass plates, and pipe gaskets. Spare part price, stock, and lead time require written confirmation.
3. Remote technical support: We offer remote guidance for installation, commissioning, and troubleshooting. Response times and service channels are confirmed in writing.
4. Maintenance planning: Operation manuals, maintenance schedules, and oil-grade recommendations are provided after order confirmation.

The client wanted to avoid being stranded with a machine that cannot be serviced. We explained that as a manufacturer, we can support both models with documented parts lists and ongoing technical communication.

Factory Attributes & Why a Real Manufacturer Matters

The client asked whether we are a genuine factory. We answered directly and truthfully:

• YG Machinery is a machinery manufacturer, not only a trading company. We are involved in production, testing, and export.
• We supply complete machine + spare parts packages so clients can maintain equipment after delivery.
• We provide export-oriented packing and full documentation for international shipment to Paraguay.
• Our engineering team supports selection, configuration, and commissioning through written proposals and remote guidance.

We did not claim factory size, export volume, certifications, or years of history without verified documents. We positioned our credibility through concrete support capability: model selection, parts supply, documentation, and after-sales communication.

What Still Needs Written Confirmation Before Ordering

To avoid any misunderstanding, we clearly listed the items that must be confirmed with YG before the client locks their order:

• Exact model selection (YG-20 or YG-30) based on site data
• Motor/engine brand and power configuration
• Concrete delivery distance and pipe layout for the chosen model
• Concrete mix requirements (aggregate size, slump)
• Spare parts package and lead time for Paraguay
• Full warranty terms and exclusions
• Export packing, port, and delivery schedule

We did not treat the order as confirmed. This is a pre-sale consultation record, not a completed sale.
