Mono Sun-Sub 400W–600W system

Mono Sun-Sub 400W–600W Solar Pump System

The Mono Sun-Sub 400W–600W Solar Pump System is a medium-size solar-powered submersible pump package designed for rural water supply, bore pumping, stock watering, tank filling, trough systems and off-grid farm water transfer.

This system is suited to applications that need more flow than a small 200W solar pump, while still being a practical option for smaller to medium rural water systems. It is commonly used on farms, rural properties and lifestyle blocks where mains power is not available or diesel pumping is not preferred.

The 400W–600W Sun-Sub range is a good option for medium trough systems, small to medium bore setups, tank filling, remote stock water and rural water supply where flow, head and daily water demand need to be matched correctly.

Best Suited For

The Mono Sun-Sub 400W–600W system is best suited for small to medium rural water applications where more daily flow is needed than a small 200W system can provide.

The 400W system may suit medium trough lines, smaller bores, tank filling and lower to medium head applications.

The 600W system may suit higher daily water demand, deeper pumping levels, longer pipe runs, extra troughs or applications where extra flow is needed.

For larger stock water systems, high head, long pipe runs, bigger tanks or multiple troughs, a larger Mono Sun-Sub system may be required.

Choosing the Right System

When selecting a Mono Sun-Sub 400W or 600W system, consider:

Bore depth
Standing water level
Pumping water level
Total head height
Pipe size
Pipe length
Elevation
Number of troughs or tanks
Required daily water volume
Bore yield
Solar exposure
Fittings, valves and friction loss

Important Sizing Note

The 400W–600W Sun-Sub system must be matched to the site. Flow rates can reduce with higher head, longer pipe runs, smaller pipe sizes, poor solar exposure, low bore yield, elevation, fittings and valves.

A 600W system will generally provide more daily water than a 400W system, especially where the pumping head is higher or the water demand is greater.

FAQs

What is the Mono Sun-Sub 400W–600W system used for?

The Mono Sun-Sub 400W–600W system is used for rural water supply, bore pumping, stock watering, trough systems, tank filling and off-grid farm water transfer.

Is the 400W–600W Sun-Sub suitable for stock water?

Yes. It can be suitable for small to medium stock water systems, depending on head height, bore yield, pipe distance, number of troughs and required daily water volume.

How much water can the Mono Sun-Sub 400W pump?

As a guide, the 400W system can pump approximately 71 kL/day at 5m head, 45 kL/day at 20m head, 22 kL/day at 40m head, 13 kL/day at 60m head and 5 kL/day at 120m head under good solar conditions.

How much water can the Mono Sun-Sub 600W pump?

As a guide, the 600W system can pump approximately 107 kL/day at 5m head, 62 kL/day at 20m head, 35 kL/day at 40m head, 23 kL/day at 60m head, 11 kL/day at 100m head and 4 kL/day at 150m head under good solar conditions.

Does the Mono Sun-Sub 400W–600W system need mains power?

No. The system is solar powered, making it suitable for remote areas where mains power is unavailable or where diesel pumping is not preferred.

Should I choose the 400W or 600W system?

Choose the system based on bore depth, pumping water level, total head, pipe distance, required daily water volume and solar exposure. The 600W system is generally better where more flow or higher head capacity is required.

Disclaimer

Flow rates shown are manufacturer-published guide figures based on controlled testing and good solar conditions. Actual flow rates may vary depending on sunlight, location, bore depth, water level, pipe size, pipe length, elevation, fittings, valves, bore yield, system design and installation conditions.

Flow rates are provided as a guide only and should not be relied upon as guaranteed performance. For best results, contact The Pump Shed Australia with your bore depth, distance, height lift and required daily water volume so the correct Mono Sun-Sub system can be selected.
