Umbra Pompe Acuatec Submersible Well Borehole Pump (5 inch)

5” Borehole Pump for Balanced Pressure and Flow

The All-Round Balanced Option for Most Borehole Installations

The Acuatec is a 5 inch submersible borehole pump designed to provide a balance of pressure and flow, making it the most versatile option within the range.

It is typically used for irrigation, agricultural and general water supply where both pressure and flow are required, rather than prioritising one over the other.

Where the Acuatec is used

The Acuatec is suited to:

• 5” boreholes
• Irrigation systems
• Agricultural water supply
• General water transfer and supply
• Industrial and processing applications

It is the right choice for most installations where requirements are mixed.

Why choose the Acuatec

• Balanced performance between pressure and flow
• More versatile than high-pressure or high-flow specific pumps
• Available as manual or automatic (float switch)
• Suitable for regular use in irrigation and water supply applications
• 230V single phase supply

How it operates

The Acuatec is available in two versions:

• Manual version – runs continuously when powered
• Automatic version – uses a pendant float switch to operate based on water level

The float switch requires space to move freely, so:

• It is generally not suitable for narrow boreholes
• More suited to tanks, wells or larger chambers

On manual models, flow can be controlled by including a pressure controller in the delivery line.

Build and design

The Acuatec is a multi-stage pump designed for both pressure and flow.

• Stainless steel body and strainer
• Multi-stage impellers
• Oil-cooled motor
• Non toxic oil
• Integral starting capacitor

The pump is suitable for clean water and can handle water containing up to 60 g/m³ of suspended solids.

Performance overview

Performance depends on the model selected.

• Flow up to approx. 90–135 litres per minute depending on model
• Head varies depending on model selection
• Maximum submersion depth: 17 metres
• Operating temperature: 0°C to 35°C

Installation

Installed within a 5” borehole, tank or chamber depending on the system.

The Acuatec has a 1¼” outlet (32mm BSPF).

It can be connected using a 32mm male BSP hose tail, suitable for:

• High pressure delivery hose
• Irrigation systems
• General water supply setups

Important notes

• Designed for clean water, including rainwater and stored water
• Can handle small suspended solids (up to 60 g/m³)
• Not suitable for sewage or heavy abrasive material
• Automatic float switch version requires space to operate
