Jet Pump Shimizu Indonesia: Buyer's Guide for Reliable Water Supply
Daftar Isiexpand_more
Understanding the Shimizu Jet Pump
Shimizu is a trusted Japanese brand widely used in Indonesia for residential and agricultural water supply. A jet pump uses an impeller and a venturi nozzle to create suction, lifting water from depths up to 9 m (self-priming) or more when combined with an ejector. These pumps are known for reliability, quiet operation, and easy maintenance. 3G Electric, a global industrial solutions provider with 35+ years of experience, supplies and delivers genuine Shimizu jet pumps across Indonesia, backed by technical support to ensure correct sizing and installation.
How a Jet Pump Works
A jet pump uses a centrifugal impeller to spin water, creating a partial vacuum that draws water from the well. The water passes through a narrow venturi nozzle, increasing velocity and reducing pressure, which lifts more water from depth. The pump recirculates a portion of the water back to the nozzle to maintain suction. This makes it ideal for wells with static water levels within 9 m of the pump (can be extended to ~30 m with a deep-well ejector kit).
Key Specifications (Typical Shimizu Jet Pump Range)
| Specification | Value Range |
|---|---|
| Flow rate | 20 L/min – 150 L/min |
| Total head (max) | 10 m – 60 m |
| Power input | 0.37 kW – 1.5 kW |
| Voltage / Phase | 220 VAC / 1-phase or 380 VAC / 3-phase |
| Connection size | DN25 – DN40 (1″ – 1.5″) |
| Max operating pressure | 6 bar – 8 bar |
| Max water temperature | 40 °C |
Types and Applications
Shimizu jet pumps are available in several construction variants:
- All-bronze impeller – for clean water, resistant to corrosion, common for household drinking water.
- Cast iron body – durable, suitable for irrigation and agricultural use where water quality is lower.
- Single-phase (220 VAC) – standard for homes and small farms.
- Three-phase (380 VAC) – for high-demand commercial or industrial applications.
In Indonesia, these pumps are most commonly used for shallow wells (jet pump without ejector) or deep wells (with ejector) to serve family homes, boarding houses, fish ponds, and smallholder irrigation.
Selection Criteria (Numbered List)
- Determine well depth and static water level. Measure the vertical distance from pump to water surface. For depths below 9 m, add a deep-well ejector kit.
- Calculate required flow rate. Sum all simultaneous usage points (taps, toilet, shower). A typical 4-person household needs 30–50 L/min.
- Compute total head. Add static lift, friction losses in pipe (use ~1 m per 10 m pipe), and pressure required at the highest outlet.
- Check power supply. Confirm voltage (220 VAC single-phase or 380 VAC three-phase) and circuit breaker capacity.
- Select material. Use all-bronze for potable water, cast iron for irrigation. Avoid cast iron if water is acidic.
- Verify certification. Look for SNI (Standar Nasional Indonesia) marking and warranty from authorised distributors like 3G Electric.
According to Shimizu Pump Product Manual, 2020: “For domestic installations, size the pump to deliver at least 120% of the peak demand to account for friction losses and future expansion.”
