The product range includes 250A, 370A, and 550A automatic pump models, allowing users to select a suitable configuration according to their required pumping performance. Each model uses an aluminum wire motor, a durable copper impeller, and a convenient 30 cm power cable for easier installation.
| Model | Stator Size | Power Rating | Motor Winding | Impeller |
| 250A | 9 cm | 90P | Aluminum Wire | Copper |
| 370A | 9 cm | 120P | Aluminum Wire | Copper |
| 550A | 11 cm | 140P | Aluminum Wire | Copper |
The three configurations provide different motor capacities for applications with varying water delivery and pressure requirements.
Unlike traditional fixed-position pumps, the Transformers Series features a compact, multi-positional architecture. Whether installed in tight utility shafts, under kitchen sinks, or in outdoor garden irrigation cabinets, this pump adapts to your space requirements.
We utilize premium brass impellers instead of cost-saving plastic alternatives. This provides:
Superior Corrosion Resistance: Ideal for long-term water contact.
High Mechanical Strength: Resists deformation under high-pressure operation.
Smooth Flow Dynamics: Ensures consistent pressure output and minimal noise.
Equipped with a micro-computerized control module, the pump offers:
Automatic Start/Stop: Instant activation when a tap is opened and shutdown upon closure.
Energy Efficiency: Precision-wound aluminum motors (90P–140P) provide excellent torque-to-power ratios, significantly reducing electricity consumption for fleet/home use.
The Moluoni Transformers Series is the go-to choice for:
Domestic Booster Systems: Solving low municipal water pressure in multi-story homes.
Garden & Greenhouse Irrigation: Delivering consistent, high-flow water to delicate sprinkler systems.
Utility & Commercial Transfer: Reliable water supply for small workshops and light commercial facilities.
Export-Ready Standards: Every unit is secured in a customized individual color box, perfect for wholesale retail display and international logistics protection.
One-Stop Procurement: We provide full documentation support, ensuring seamless customs clearance for our global partners.
Quality Assurance: 100% pre-shipment inspection on all motor performance and electrical integrity.
