The Singflo BW4003A Bottled Water Dispenser System is a versatile, plug-in pump designed to bring high-quality potable water from bottled sources to your appliances. Whether you’re running a commercial coffee brewer, an espresso machine, a fridge with an ice maker, or a water tap, this dispenser pump provides a reliable, pressurised water supply without the need to plumb directly into mains water.
At the heart of the system is a durable diaphragm pump capable of producing 40 PSI of pressure, delivering up to 3.8 litres per minute (1.0 GPM) of flow. This ensures consistent water pressure and volume, even under demanding conditions, making it well-suited for busy coffee stations or high-output appliances. The pump supports 110–240 V AC, making it compatible with various local voltages and wiring setups.
A built-in float switch on the suction wand provides two critical functions: it activates the pump when the wand is immersed in water, and it automatically shuts off when the bottle runs dry. This clever design protects the pump from running dry and prolongs its life.
The system also includes a check valve to prevent backflow, so water won’t spill back into the bottle when you’re changing bottles or shutting off the appliance. The universal seal cap fits most 20 or 25 litre plastic bottles, ensuring compatibility with a wide range of bottled water supplies.
Mounting is simple thanks to its compact form factor — at just 7.62cm H × 13.97cm W × 19.05 D, the module can be installed in tight cabinet spaces or underneath counters. Rubber feet help dampen noise, so while the diaphragm pump hums during operation, it’s quieter than many traditional plumbed systems.
Overheating is not a concern: thermal protection shuts the unit off if it gets too hot, safeguarding both the motor and control electronics. The system package includes a 6-foot power cord (with your choice of plug), a 6m length of 1/4″ discharge tubing, and the suction wand assembly.
For baristas, café owners, or home coffee enthusiasts: this pump provides a pressurised, reliable water supply from bottled water — perfect for ensuring consistent flavour extraction in your espresso or drip machines. It’s a cost-effective way to deliver clean, portable water to fridges, ice makers, or taps without costly plumbing.
Built for longevity and ease of use, the Singflo BW4003A is a smart solution when you want the flexibility and convenience of bottled water, but also need the pressure and reliability of a plumbed system — all wrapped into a compact, efficient package.
