View SpecificationsDemocratic Republic of Timor-Leste is undergoing swift infrastructure development. From municipal expansion in Dili to heavy investments in clean water networks, coffee agriculture (Ermera, Liquiçá), and mining/petroleum activities along the south coast (Tasi Mane projects), the demand for robust, reliable liquid handling is growing fast.
Many pump installations in Timor-Leste encounter issues with clogging due to dense organic solids, mud, and sand present in raw river run-offs. Conventional radial centrifugal pumps fail often under these conditions, causing motor failure and operational delays.
Screw impeller pumps (also called helical impeller pumps) combine the clog-free attributes of a progressive cavity pump with the high efficiency of a centrifugal pump. This makes them ideal for municipal sewage drainage and coffee mill wash-water recirculation.
Our screw impeller assemblies are powered by Shandong Sunvim's IE3/IE4 standard and custom induction motors. Designed with superior winding insulation and strong tolerance for voltage drops, these systems ensure constant operation even when power from the Electricidade de Timor-Leste grid fluctuates.
The single-channel screw impeller acts like a rotating Archimedes screw, creating a smooth axial movement that handles large solids up to 100mm in diameter without clogging.
| Performance Indicator | Sunvim Screw Impeller Pump | Standard Centrifugal Pump | Progressive Cavity Pump |
|---|---|---|---|
| Clog Resistance | Excellent (Single helical channel) | Poor (Prone to hair/fiber wrapping) | Good (Prone to dry running damage) |
| Solid-Passage Diameter | Up to 105 mm (Unobstructed) | Less than 25 mm | Medium (High wear on stator) |
| Shear Sensitivity | Very Low (Gentle displacement) | High (High shear damages fluids) | Low |
| Energy Efficiency (Total System) | Up to 82% (IE4/IE5 Motor paired) | 65% - 75% | 60% - 70% |
| Maintenance Interval | Extended (No close-clearance wear rings) | Frequent wear-ring replacements | Frequent stator replacements |
Our screw impeller pumps utilize a steep H-Q (Head-Flow) curve. This means that even if the discharge pressure varies, the flow rate remains stable. Paired with Sunvim High-Efficiency IE3/IE4/IE5 motors, these pumps lower your energy usage, reducing operational costs across municipal wastewater stations in Dili and agricultural irrigation setups in Liquiçá.

Shandong Sunvim Motor utilizes a highly integrated manufacturing process. By keeping casting, core punching, stator winding, rotor dynamic balancing, and assembly testing inside a single facility, we eliminate external logistical delays.
This vertical integration allows us to offer shorter lead times and maintain consistent quality across all components. For Timor-Leste buyers, this means reliable production schedules and fast container processing from the port of Qingdao direct to the port of Dili.
We work with major logistics partners to offer flexible shipping terms (FOB, CIF, CFR) to Dili Port. All electrical systems are packed in seaworthy, vacuum-sealed wooden crates to prevent moisture damage during sea transport through tropical zones.
Pricing varies based on material requirements (Cast Iron, SS304, SS316, or Duplex Steel) and the efficiency class of the integrated electric motor. Below is a baseline price matrix for typical pump-motor configurations.
| Pump Inlet Size | Motor Drive Option | Rated Flow (m³/h) | Rated Head (m) | Baseline Price Range (USD) |
|---|---|---|---|---|
| DN 50 (2 inch) | IE3 High Output 5.5 kW | 15 - 30 | 12 - 18 | $1,800 - $2,400 |
| DN 80 (3 inch) | IE3 High Output 11 kW | 40 - 75 | 15 - 25 | $2,900 - $3,800 |
| DN 100 (4 inch) | IE4 Premium 18.5 kW | 80 - 150 | 18 - 32 | $4,500 - $5,800 |
| DN 150 (6 inch) | IE4 Premium 37 kW | 180 - 300 | 22 - 40 | $7,200 - $9,500 |
| DN 200 (8 inch) | IE5 Ultra-Efficient 75 kW | 350 - 500 | 25 - 55 | $12,500 - $16,000 |
While IE4 and IE5 configurations have a higher upfront purchase cost, their lower energy consumption can help recover the cost difference within 12 to 18 months of operation, especially under Timor-Leste's industrial electricity rates.
