Versatile pumping for rainwater, irrigation & emergency use
From emergency water removal to everyday system support, it delivers reliable performance across a wide range of clean water applications. This pump is ideal for dewatering flooded basements, pits, and garages, with fast, efficient pumping when response time matters most.

Its 32 m head also makes it well-suited for AWTS discharge and drip irrigation on sloped terrain, where elevated pressure is essential.
Smart choice for small Homes, big Performance for clean water systems
While it supports light domestic boosting (homes with 1–2 bathrooms), larger households with higher demand benefit from a higher-capacity pump. Whether you are transferring water between tanks or irrigating a landscape, the BIA-B42A is engineered for efficient, real-world performance. Compared to basic drainage pumps, this clean water pump offers multistage pressure performance. Therefore, it bridges the gap between high flow and high head in a compact, submersible design.
Clean or sedimented water? This Bianco rural pump can candle it
The Bianco submersible pump efficiently processes clean and slightly dirty water with particles up to 3 mm. Thus, it is ideal for rainwater harvesting, greywater reuse, and tank-to-garden systems. Its elevated intake draws water from above the sediment layer, helping to prevent sludge buildup. Ultimately, this is a significant advantage over standard bottom-draw pumps. Consequently, cleaner water, less clogging, and longer pump life result. Whether it's a rural setup, off-grid home, or backyard system, it delivers reliable flow and pressure even when water quality isn't ideal.
Bianco BIA-B42A – Corrosion-resistant pump for long-term performance
This rainwater pump features a durable, corrosion-resistant body made from glass-filled nylon, paired with a stainless-steel strainer that resists wear and protects internal components. A built-in float switch enables automatic operation based on water level — ideal for unattended rainwater tanks, pits, or AWTS systems. This robust construction minimises damage from harsh water conditions, reduces maintenance needs, and delivers dependable, low-touch performance in residential and light commercial environments in NZ.
Built for safety: Submersible protection with overload shutoff
Designed for safe, long-term submersion, the Bianco BIA-B42A is rated IP68, ensuring complete protection against dust and water ingress. It also features a built-in thermal overload switch, automatically shutting the pump off to prevent motor damage during overheating. These safety features enhance durability, reduce the risk of failure, and make the BIA-B42A a dependable choice for submersible clean water applications in residential, commercial, or off-grid systems.

Steve's Pros & Cons
Pros of the Bianco submersible clean water pump
Fully submersible water pump for easy, reliable water transfer
This submersible high head pump designed for AWTS and rainwater tanks is built to be completely submerged in water. Hence, making it perfect for transferring clean water from tanks, wells, or sumps. Whether you’re managing rainwater collection or drawing from a bore, its submersible design means it can sit directly in the source—no need for complicated setups or suction hoses.
Bianco submersible clean water pump : Ultra-quiet operation underwater
Since the motor runs below the surface, it’s naturally insulated by the surrounding water. That makes this vertical multistage pump extremely quiet, ideal for situations where you want peace and quiet, such as in residential tanks or holiday homes. You’ll barely notice it’s running—until you see the results.
Low maintenance and straightforward installation: Submersible water transfer pump
Designed with simplicity in mind, the Bianco high head submersible pump is easy to install and requires minimal upkeep. Once in place, it gets the job done without fuss, making it a popular choice for homeowners and DIYers alike. Fewer moving parts and no priming required mean less hassle over the long term.
Affordable and dependable submersible domestic pump – no frills, no fuss
It’s not fancy, but it works. The Bianco BIA-B42A pump is a budget-friendly solution that delivers solid performance for clean water transfer tasks. If you’re after a submersible pump that does what it says on the box—with no unnecessary extras—this one ticks all the right boxes.
Call 0800 278 288 now and skip the “trial and error” phase. We’ll match the pump to your job.
Cons of the Bianco submersible clean water pump
Submersible water pump for clean water use only – no tolerance for grit or sludge
This Bianco submersible pump is designed exclusively for clean water. It’s not suitable for handling dirty, sandy, or abrasive liquids, which can clog or damage the motor. That said, it’s still a great fit for clean zones, such as the clarified side of a septic tank or filtered rainwater tanks.
Bianco submersible clean water pump : Needs to stay fully submerged to prevent damage
To keep cool and avoid overheating, this submersible pump for dewatering must remain completely underwater during operation. If the water level drops too low, the pump risks running dry and overheating. It’s important to ensure your tank or sump won’t run dry while the pump is active—especially if set on a timer or float switch.
Power cord length may limit placement : Submersible rainwater tank pump
Depending on your tank or sump setup, the standard power cord length may not always reach your desired outlet location without an extension. This can be inconvenient if your power source is far from the pump location, especially in rural or large property settings.
Bianco BIA-B42A : Not suitable for constant or heavy-duty commercial use
While perfect for domestic water transfer tasks, this submersible water pump isn’t built for continuous operation or industrial-grade applications. It’s best suited to light-duty, intermittent use—pushing it beyond that can shorten its lifespan or reduce performance over time.
