About Aquastrong Water Pumps

Aquastrong is a dedicated water pump brand based in Italy and established in the 1990s, with pump products for domestic, garden, agricultural and commercial water applications. The Aquastrong electric pump range includes options for household pressure supply, garden water use, clean water transfer, deeper suction applications, bore pumping, drainage and wastewater pumping.

GoodsDirect2U supplies Aquastrong water pumps in New Zealand across several pump types, including booster pumps, jet pumps, deep well jet pumps, multi stage pumps, variable speed pumps, submersible pumps, sewage pumps and centrifugal pumps. Choosing the right Aquastrong pump depends on the water source, suction depth, flow rate, required pressure, pump head and installation setup.

Choosing the Right Electric Water Pump

Before choosing an electric water pump, consider where the water is coming from, how far it needs to travel, the vertical lift, pipe size, required flow rate, required pressure and whether the pump needs to suck water up from below the pump. A pump with a high maximum flow rate may not deliver that same flow once it is working against head, pipe friction, filters, fittings or suction lift.

If you are unsure what size pump you need, see our Water Pump Flow Rate & Head Guide. It explains typical flow rates, rough pressure targets, how to calculate pump head and how to read a pump curve.

Types of Electric Water Pumps

• Booster pumps: Used to help increase water pressure in suitable household, garden, tank or water supply systems. Booster pumps can be useful where extra pressure is needed for taps, showers, irrigation, tank water or general water transfer, depending on the pump model and setup.
• Centrifugal pumps: Best suited to clean water transfer where the pump has water feeding into it, such as a tank outlet or positive pressure supply. Centrifugal pumps are generally not good at sucking water up from below the pump, so they are usually better where the inlet is already flooded or water is gravity-fed into the pump.
• Jet pumps: One of the most popular surface pump options for household tank water and lifestyle block water supply. Jet pumps can draw water from a tank, shallow well or water source and are generally used where suction lift is up to around 7–9 metres, depending on installation, pipe size, priming and conditions.
• Deep well jet pumps: Used for deeper suction applications where a standard jet pump is not suitable. Deep well jet pump setups can draw from deeper sources, commonly up to around 15 metres, and require two pipes in the suction line.
• Multi stage pumps: Designed for higher pressure applications and steady water supply. Multi stage pumps can often deliver strong performance with lower power use compared with a similar jet pump setup, especially where water is already feeding into the pump and suction lift is not required. They are also often quieter than jet pumps, which can make them a good option when the pump is installed close to the house.
• Sewage and sewerage pumps: Used for wastewater, grey water or sewage applications, with cutter and non-cutter options depending on the type of waste being pumped.
• Submersible pumps: Designed to sit in the water source and pump water out. This range can include bore pumps, deep well submersible pumps, drainage pumps and general submersible pumps with float switches.

Pressure Switches for Electric Pumps

A pressure switch helps an electric water pump start and stop automatically as water is required. Without a pressure switch or flow sensor, a pump may continue running instead of turning on and off on demand.

A pressure switch is normally installed after the outlet of the pump. When pressure drops because a tap, shower, hose or outlet is opened, the pressure switch can turn the pump on. When water stops flowing and the pressure recovers, the pressure switch can turn the pump off again. Some pressure switches have adjustable cut-in settings, and some models may include run-dry protection.

When choosing a pressure switch, make sure the switch is suitable for the pump’s power requirements, pressure range, pipe size and application. Matching the pressure switch output power range to the pump’s overall power requirement is important.

Pressure Tanks and Why They Help

A pressure tank can be fitted with a suitable pressure switch to reduce how often the pump starts and stops. This can be helpful for small water uses such as filling a glass, washing hands or a toilet cistern refilling, where you may not want the pump to start immediately for a small amount of water.

By storing pressurised water, a pressure tank can reduce pump cycling, reduce wear and tear, reduce pump noise during small water draws and help extend the life of the pump. Because pumps use a higher amount of power when starting, reducing unnecessary starts may also help reduce overall power use in suitable systems.

Pressure tanks are commonly installed inline after the pump and pressure switch. The correct tank size depends on the pump, water use, pressure settings, available space and how often small amounts of water are used.

Jet Pumps vs Centrifugal Pumps

A jet pump is usually the better choice when the pump needs to draw water up from below the pump, such as from a tank, shallow well or water source where suction lift is required. Jet pumps are self-priming surface pumps and are one of the most common choices for household tank water systems and lifestyle block water supply.

A centrifugal pump is generally better when water is already feeding into the pump. For example, it may suit a setup where the tank outlet is above the pump or the pump has positive inlet pressure. Centrifugal pumps are usually not the best choice where the pump needs to suck water up from below the pump.

For deeper suction applications, a deep well jet pump may be required. These use a two-pipe suction setup and can suit deeper sources where a standard jet pump is not suitable.

Jet Pumps vs Deep Well Jet Pumps

A standard jet pump is usually used where the pump is above the water source and the suction lift is within a normal shallow suction range, often around 7–9 metres depending on the installation. These pumps are commonly used for tanks, shallow wells and general household or garden water supply setups.

A deep well jet pump is different. It is designed for deeper suction applications and uses a two-pipe suction line. This can suit water sources where the suction depth is greater than a standard jet pump can handle, commonly up to around 15 metres depending on the installation. Correct pipe setup, priming and installation are important for deep well jet pump performance.

Multi Stage and Variable Speed Pumps

Multi stage pumps use multiple impellers and diffuser stages to help build pressure efficiently. Compared with many jet pump setups, a multi stage pump can often deliver strong pressure and flow with lower power use, especially where water is already feeding into the pump and suction lift is not required.

Multi stage pumps can be a good option for household water pressure, tank water supply, irrigation, pressure boosting and clean water systems where steady pressure is important. They are also often quieter than jet pumps, which can make them a better choice when the pump is installed near a house, garage, shed or living area.

Variable speed pumps are designed to adjust the pump speed depending on water demand. Instead of running at full speed every time water is used, a variable speed pump can slow down for lower demand and increase speed when more water is needed.

This can help maintain more consistent water pressure when taps, showers, hoses or irrigation outlets are turned on and off. In suitable systems, variable speed operation may also reduce pressure fluctuations, reduce pump cycling, reduce stress on pipework and fittings, and reduce power use compared with a standard fixed-speed pump setup.

Variable speed pumps are also much quieter than many standard pump setups, which can make them a good option when the pump is installed close to the house, garage or living area. For example, if only one tap is opened, the pump may run at a lower speed and quieter operating level. If a shower and outdoor tap are used at the same time, the pump can increase speed to help maintain the set pressure.

Submersible, Bore and Sewage Pumps

Submersible pumps are placed in the water source instead of sitting above ground. This makes them useful for bores, tanks, sumps, ponds, drainage jobs and other applications where the pump needs to work from inside the water. Some submersible pumps include float switches, which can turn the pump on and off automatically as the water level changes.

Deep well submersible bore pumps are commonly used for pumping water from bore holes or deeper water sources. They can be used for filling storage tanks, supplying irrigation, filling troughs, garden water supply, lifestyle block water systems and other clean water transfer jobs where the water source is below ground.

When choosing a bore pump, check the bore size, bore depth, water level, flow requirement, total head, cable length, pipe size and power supply. The pump must be matched to the bore and the required flow at the head it will be working against.

Sewage and sewerage pumps are designed for wastewater applications and may include cutter and non-cutter options depending on the pump model and the type of waste being pumped. Always check the product listing to confirm whether the pump is suitable for clean water, dirty water, grey water or sewage use.

Flow Rate, Head and Pressure

Electric water pump listings often show maximum flow rate in litres per minute, but this is usually measured at low head. Real-world performance depends on the head the pump is working against. Head can include vertical lift, pipe length, pipe diameter, fittings, filters, valves, suction lift and the pressure required at the outlet.

For example, a pump may show a high maximum flow rate, but the actual flow will reduce as head and pressure increase. This is why the pump curve is important. The pump curve helps show the approximate flow rate the pump may supply at different head levels.

Electric Water Pumps for Homes, Farms and Lifestyle Blocks

Electric water pumps can be used for many home, farm and lifestyle block water jobs, including tank water supply, household pressure boosting, garden watering, irrigation, bore pumping, drainage, wastewater and clean water transfer. The correct pump depends on the water source, suction lift, head, flow requirement, pressure requirement and whether the water is clean, dirty or wastewater.

For household and tank water supply, jet pumps, booster pumps and multi stage pumps are common options depending on the setup. Jet pumps are popular where suction lift is required, while multi stage pumps can be a quieter and more efficient option where water is already feeding into the pump. For drainage, bores or water sources where the pump needs to sit in the water, a submersible pump may be more suitable. For wastewater or sewage applications, use a sewage or sewerage pump designed for that purpose.
