What is a Puddle Pump?
What is puddle pump?
Also known as a puddle sucker or residue pump, puddle pumps are a type of submersible pump that is designed to remove excess water from flat surfaces such as floors, cellars, basements and flat roofs.
Unlike a traditional submersible water pump, puddle pumps do not need to be fully submerged to operate effectively - able to pump down to 1mm without overheating. They do not require a chamber or sump to operate and are compact in size, making them ideal for quick deployment in flooding and emergency response situations.
How do puddle pumps work?
Puddle pumps use an impeller to generate a centrifugal force that transports water away from the surface they are placed on. A seal and volute in the base of the pump allow them to pump as low as 1mm, while an integrated non-return valve prevents water backflow.
Puddle pumps can be manually controlled or paired with water level sensors and a suitable control panel for automatic dewatering.
How to choose a puddle pump
There are many different puddle pump models available on the market, all with different power outputs, discharge sizes, maximum submersion depths and solids handling capabilities.
Here are some points to consider when choosing a puddle pump for your application:
- What liquid is being pumped?
- How deep is the liquid to be pumping?
- How quickly do you need to pump the water?
- Do you require manual or automatic pumping?
At T-T pumps we offer a range of puddle pumps for different applications, al of which are capable of pumping down to 1mm, including:
A range of cast iron and stainless steel pumps with high abrasive resistant resin vortex impellers, available with a range of pumping capacities and speeds.
A more compact puddle pump, made of corrosion and shock-resistant polypropylene and high-grade stainless steel, ideal for emergency dewatering.
A compact and fully stainless-steel puddle pump for corrosive applications such as salt water, quarries and mining, civil construction and emergency dewatering.
A completely automatic dewatering set, including a PuddlePal puddle pump, Waterguard control panel and Watervole level sensor.
Frequently Asked Questions
What volume of water can be pumped by puddle pumps?
The volume of water a puddle pump can pump varies depending on the specific model’s motor power, impeller design, inlet/outlet size and application conditions.
A puddle pump’s maximum capacity will be specified within its user manual, our PuddlePal 400 has a maximum pumping capacity of 6000 litres per hour, but this can vary depending on the specific application.
How are puddle pumps different from traditional submersible water pumps?
Puddle pumps are designed to pump liquid from flat surfaces and do not require installation into a chamber or sump to operate.
Because Puddle pumps do not have to be completely submerged to operate, they are capable of pumping liquid down to 1mm without overheating or motor damage from dry running.
What are the different applications of puddle pumps?
Puddle pumps are suitable for dewatering flat surfaces such as flat roofs and floors, perfect for flood protection and drainage in basements and cellars.
Do puddle pumps need to be fully submerged to function effectively?
Puddle pumps do not have to be fully submerged to operate and can pump down to 1mm.
The pumped liquid passes between the pump casing and motor, cooling the motor as it flows through the pump and preventing overheating.
Can puddle pumps be operated automatically?
Most puddle pumps can be operated automatically when paired with a compatible control unit and level control device.
Our Waterguard/Waterguard Pro and Water Vole low level sensors are suitable for use with our puddle pumps for automatic dewatering.
