Submersible Pumps

Pumps that are at home in the water. When looking for the best submersible pump for your needs, there are a few things to keep in mind. It's a good idea to decide what type of water needs to be drained and whether the pump should turn on and off automatically. What's the difference between a puddle pump and a dirty-water pump, by the way? This article aims to make it easy for you to select a pump that matches your needs. If you want to buy a submersible pump, read the steps below carefully and choose the right pump for you.

What should you keep in mind while purchasing a submersible pump?

Pumping Power

A submersible pump's pump ability (also known as flow rate) decides how many litres per hour the device can process in the best possible situation: that is, without resistance and without the need to pump the water upwards. When choosing the correct submersible pump, the delivery head and pumping ability are vital considerations. After all, you don't want to have to wait indefinitely for a given place to be emptied.

Quick Tip: When choosing a submersible pump, look at the 'flow rate table,' which displays how much water the pump can drain per hour at different delivery heads (the height at which a pump can raise water).

The Delivery Head

The delivery head indicates the maximum distance a submersible pump can pump water through a discharge hose/tube. It is based on a wide discharge hose/tube with the least amount of resistance.

Quick Tip:

When deciding which submersible pump is suitable for you, give yourself a lot of leeways. Suppose the device must pump water five metres higher in your situation. In that case, you should choose a submersible pump with a delivery head of at least seven metres.

What type of water?

When choosing the best submersible pump, it's crucial to consider the sort of water the pump will be processing; we've classified these into four categories.

Clean Water - Water that is free of contaminants

This refers to pure, clear, and almost potable water with no or few solid particles (sand). Any submersible pump can handle this type of water. In this situation, you need to think about the other aspects of selecting the best submersible pump.

Water that is slightly soiled This sort of water is somewhat cloudy and has sand or other small solid particles less than 10 mm in size. Water from a flooded cellar, bathwater, and rainwater combined with road dirt are all examples.

Wastewater/dirty water

Cloudy water with larger solid particles, up to 50 mm in size depending on the pump, falls into this group. Construction sites, agricultural/cattle farms, and industrial sites are all places where these pumps are used. The FEKA series is also proper for draining faecal matter-laden water.

Salt Water

Is there anything that saltwater doesn't ruin? Processing saltwater is a different beast, even for submersible pumps. However, there is one hero we can always count on to help us deal with this problem: the DAB Nova Salt M-A.

How does a float work when it is automatically activated?

Most of the submersible pumps in our product line have a 'float,' which acts as a form of the switch for the pump. It floats on the water and hence rises with the water level, as its name implies. The float will have achieved the pump's activation level when it reaches a particular height, ensuring that the pump turns on and runs until the deactivation level is reached.

Activation level

Every submersible pump with a float has its moment of activation, which can range from around 8.5 cm to roughly 30 cm in water. When choosing a pump, keep in mind that the pump must reach a certain level before turning on automatically.

You can manually run a submersible pump. By 'securing' the float, which involves fixing it securely at the activation level, all submersible pumps with a float can be used in this way. When it comes to puddle pumps, all you must do is turn the side handle. In the case of submersible pumps with a loose float, such as a float cable or float arm, the float must be fastened using a tie wrap. In that scenario, make sure the float's tip points upwards so that the submersible pump is activated.

Pump for puddles A submersible pump drains water until just a few millimetres stay. In contrast, a puddle pump drains water to a level of 0 to 2 mm on a flat surface. A puddle pump is proper in a home with flooded spaces that must be drained to almost 'mop dry.'

Long-term usage

Long-term usage of domestic rated pumps will result in loss of functionality. DAB submersible pumps were explicitly created for this type of use.

If you have a difficult job ahead of you, we recommend investing in a high-quality pump. It will be the most beneficial in the long run.
