Overview

Greater pumping head for higher-lift installations

This 0.7kW submersible bore pump offers greater pumping head than the smaller models in the 3SHM range, making it an option for installations with greater lift or delivery-pressure requirements.

Suitable applications include household water supply, irrigation and transferring water to storage tanks, where its performance matches the required flow and head.

Supplied complete with a motor, 35-metre electrical cable and a surface-mounted control box.

Selection depends on your bore diameter, pumping water level, available water yield, required flow and delivery pressure—not simply the bore’s total depth.

Correct motor cooling is essential. Installation must provide the required water flow past the motor. Tank, reservoir or wider-bore installations may require a cooling sleeve.

Contact us with your bore details and water requirements for help choosing.

Performance

• Maximum head: approximately 113 metres
• Flow at 20 LPM: approximately 94 metres head
• Flow at 30 LPM: approximately 79 metres head
• Flow at 40 LPM: approximately 48 metres head
• Published performance range: 0–40 litres per minute
• Maximum starts: 30 per hour

Follow the green curve for model 3SHM1.8/27. Available head decreases as flow increases.

Allow for the lift from the pumping water level, elevation to the destination, pipework losses and pressure required at the delivery point.

FAQs

Will this pump fit my bore?
The manufacturer specifies a minimum well diameter of 3". Check the bore’s actual internal diameter, joints and any restrictions to ensure adequate installation clearance. The installation must also provide the required cooling flow past the motor.

Does the included control box automatically respond to water demand?
No. The supplied control box includes a run capacitor, isolator switch and manual-reset overload protection. Separate compatible controls are needed for automatic operation based on water pressure or tank level. Contact us for help selecting these.

Is it ready to plug in and use?
The cable is already wired into the pump, and the control box has a 3-pin plug. However, the pump cable is supplied disconnected from the control box and must be connected by a qualified electrician before use.

Can it deliver 40 litres per minute at 113 metres of head?
No. For model 3SHM1.8/27, the published performance is approximately 48 metres head at 40 LPM. Follow the green curve to check the head available at your required flow.

How do I know whether it will deliver enough pressure?
The pump must overcome the lift from the pumping water level, elevation to the destination and pipework losses, while still providing the pressure required at your outlets. Send us your installation details so we can help check the required flow against the performance curve.

Can I install it 80 metres down?
The 80-metre maximum immersion rating is separate from pumping head and total installation depth. Suitability depends on the pumping water level, required flow and delivery pressure.

The supplied cable is 35 metres. Deeper installations require suitable additional cable and correctly rated connections.

Can I use it in a tank or reservoir?
Potentially, provided the installation delivers sufficient cooling flow past the motor. A cooling sleeve may be required in tanks, reservoirs or wider bores. Contact us before choosing this pump for those applications.

Can it pump sandy water?
The manufacturer’s information supplied does not specify a permitted sand content. Contact us with details of your bore’s water quality so we can confirm suitability before you order.

Does it include a non-return valve?
Yes. A non-return valve is incorporated into the pump. Any additional valves should be selected and positioned according to the installation instructions and system requirements.

Does it have dry-run protection?
The listed thermal and overload protection should not be treated as dry-run protection. If your bore could run low, contact us about suitable protection against loss of water.

How often can it start?
The manufacturer specifies a maximum of 30 starts per hour. Correctly selected controls and, where appropriate, a pressure tank can help manage frequent starts.

Can it supply irrigation or fill a storage tank?
Yes, where its performance meets the required flow and head, and the bore can sustainably supply that flow. Tank-filling and irrigation installations may require different controls—contact us for help choosing.

Will it make bore water safe to drink?
No. The pump moves water; it does not filter or disinfect it. Bore water may require testing and treatment before drinking. See our Why Filter Your Water? guide.

Are spare parts available?
Contact us with the model/SKU, photos and details of the part required. We can confirm the correct replacement and its availability.

What information do you need to help me choose?
Please send your bore’s internal diameter, total depth, static and pumping water levels, bore yield, required flow, delivery elevation, pipe lengths and sizes, and pressure needed at the destination. Include any available bore report and details of existing equipment.
