Ready for the rain?

A drainage pump for your house and garage.

Help prevent major flooding, heavy rainfall, burst pipes, faulty washing machine... Drainage pumps will allow you to dry out the flooded premises almost completely by hand, depending on the square metres.

Bear in mind that there are drainage or drainage pumps for clear or loaded water. In our catalogue you can find different systems and models, depending on your needs. Most drainage pumps are small, portable and practical pumps that can save you a lot of trouble and money.

What you should know before choosing your drainage pump

• Its purpose or use: to select the most suitable drainage pump, you must know exactly what its purpose will be or what it will be used for.  It is not the same to extract clean water from a well or tank to irrigate a crop as it is to drain dirty water from a basement, as a result of flooding..
• The type of water: this refers to whether the water is clean and free of sediment of relevant size, or whether it is dirty, stagnant and contains sludge. For each case the pump will be different.
• Particle size: it is not enough to know whether the water is clean or dirty, we must also be clear about the size of the particles. If the water contains stones or suspended particles of different sizes, you must choose a drainage pump that can adequately filter these materials.
• The power: depending on the use you will give to your pump, you will require more or less power.  For example, if it will be used to move water from one place to another, it will need sufficient power and a sufficiently long pipe.

Submersible pumps or surface pumps?

Based on the above, you will need to consider whether or not you will need to submerge the pump. If you are evacuating flood water, a submersible pump is best.

Surface pumps, on the other hand, are typically used for pumping water from springs and shallow wells, ditches or for stormwater disposal.

Submersible pumps have a sealed, watertight motor that can be fully submerged in a fluid to pump it to the surface. Surface pumps, on the other hand, cannot be submerged. They are placed in dry, protected locations close to the water source. They draw the fluid by suction from the source up to 8 metres deep and are usually electric. They use considerable energy to operate and are noisier than submersible pumps.

Generally, drainage pump motors can draw liquids at a maximum of 40°C. Cast iron pump casings, such as the Drainex, can be submerged to a depth of up to 8 metres and can be used in industry due to their high pumping capacity. Drainage pumps with plastic casings, such as the Vigilex and Vigila, are often used in the domestic sector, especially for draining water from garages or storerooms in the event of flooding. They can be submerged up to 2 and 7 metres and withstand up to 40°C.

You should also consider approximately how much water you will need to extract. This will tell you whether you should use a submersible water pump or a surface pump.

Drainage pumps for clean water and dirty water

Submersible drainage pumps can be used to extract clean and dirty water, but first we must review their specifications and functionalities.

Drainage pumps for clean water should be used when the liquid does not contain particles or if these are 5 to 10 mm in size, depending on the pump used. This is the case for water extraction in tanks, reservoirs or swimming pools. Dirty water pumps, on the other hand, are made to work with water containing larger particles of 25 to 65 mm. They are often used for draining water in cleaning and flooding works, ponds, ditches and dikes.

If the pump is submersible for dirty water, it should run as deep in the water as possible. Its return hose should be located as far away from the pump as possible. This ensures better water circulation and greater efficiency.

Installation tips

• You should make sure that the pump you choose can cope with the passage of solid particles because it could break if they are too large or if there is too much sand

• You can place the pump on a water permeable support and not directly on the ground so that it absorbs less loaded water if necessary.

• Avoid running the pump dry for more than a few minutes as the motor will overheat and cause irreparable damage.
