TOP 5 submersible pumps for dirty water with float switches

Equipment of this class, such as Karcher SP 1 Dirt, is called entry-level pumps. Due to the low-power engine (250 W), the performance of this device does not exceed 5.5 m³ / h, and the maximum head is 4.5 m. But even such characteristics are quite enough to drain garden ponds and pump water from pools or flooded boats. Although the pump cannot create a pressure of more than 0.5 bar, this is often enough to organize irrigation in the country, if water is taken from a barrel or a shallow reservoir. The device can work in manual and automatic modes. In manual mode, it works non-stop until 25 mm of water remains in the reservoir or container (“this model cannot pump dry”). And in the “auto” mode, the device turns on and off with a float depending on the liquid level.

The body and impeller are made of plastic, so the pump is light (it weighs only 3.7 kg). It has a handle for which the device can be carried in the hands or hung on a rope when immersed in a container or lowering the Karcher into a well. The device works almost silently - this is a huge plus against the background of growling "state employees" of Chinese or domestic production.

Despite the low price and simple design, Karcher SP 1 Dirt is durable (the manufacturer gives a 5-year warranty, subject to registration on the site). It has a ceramic mechanical seal that protects the impeller shaft from dirt getting inside. The device does not require maintenance during operation (except for rinsing with clean water after each use). Therefore, even your elderly relatives or people who are not at all friendly with technology will cope with it. The Quick Connect system allows you to connect the hose to the spigot without fiddling with clamps.

If you are not satisfied with the performance of this unit, then in the line of Karcher submersible pumps you can find more powerful models that can pump 7, 9.5 or 15 cubic meters of liquid per hour. And if you need to pump out dirty water “dry” (up to a level of 1 mm), then you should buy Karcher SP 5 Dual.

Einhell GC-DP 1020 N is the fastest machine among all Einhell drainage pumps. Thanks to a powerful electric motor (1000 W), it is characterized by high productivity and is capable of pumping 18 cubic meters of water every hour, creating a pressure of up to 9 meters. Therefore, the optimal scope of this pump is the rapid pumping of dirty liquid from flooded basements or drainage of areas from melt water during sudden warming.

An interesting feature of this model of equipment is the almost completely metal construction. The pump housing and impeller are made of good stainless steel, so the machine is not subject to corrosion. The abundance of metal in the design and a large powerful engine made the pump heavy (7.2 kg), so it is better for the elderly and pregnant not to lift it on their own. The outlet is designed to accept 1 1/2" (38 mm) hoses. But the kit also includes a set of universal adapters that allow you to use 3/4" (19 mm), 1" (25 mm) and 1 1/4 hoses. " (32 mm).

Einhell GC-DP 1020 N is by no means expensive, because it costs less than $ 100 - quite cheap by the standards of drainage pumps. But keep in mind that Einhell produces household-grade tools and pumping equipment. You should not buy equipment of this brand if you plan to drive the pump into the tail and mane, draining pits at construction sites or pumping out septic tanks to order.

The Metabo TPS 14000 S Combi pump with a 770 W motor can pump up to 14 cubic meters of water per hour. The design of the device provides the ability to work in two modes. He is able to pump dirty liquid (with particles up to 20 mm in size), turning on and off according to the position of the float, or pump out water "dry" - up to a level of 1 mm. Switching between modes is implemented in a very original and convenient way for users. The corresponding buttons are not located on the body of the device, but are built into the plug. That is, you do not have to put on rubber boots and go down to a flooded basement to switch the pump to another mode.

The pump body is made of impact-resistant plastic (with individual parts made of stainless steel). Therefore, the device turned out to be durable. Weighing in at 7.7kg, it's not exactly light, but the two side handles make it easier to carry or load the pump into the trunk.

The reliability of the mechanisms is ensured by a double mechanical seal, which prevents dirt from getting inside. The device is equipped with protection against dry running and an automatic switch when the engine overheats. The swivel is 1 1/2" in diameter, but other hose sizes can be connected to the pump using the universal fitting (included).

The Metabo TPS 14000 S Combi is quiet (the basement pump won't disturb your sleep). Therefore, it is perfect for working in private houses and summer cottages, which are flooded due to rains in autumn or due to flooding of rivers in spring. It can also be used to drain pond pools or water gardens and lawns.

In terms of price-quality ratio, this device is one of the best on the market. Among other Metabo drainage pumps, the Metabo TPS 16000 S Combi deserves attention - a slightly more expensive model with an increased pumping speed of up to 16 m³ / h.

Pedrollo Top Vortex has a centrifugal design. It can pump polluted water with particles whose size does not exceed 25mm. Therefore, this pump can be used for draining flooded basements and cellars, pumping water from ponds and pools, as well as solving a variety of tasks related to watering and irrigation. It is also often placed in septic tanks to pump out dirty water that collects on top of settled domestic sewage.

Pedrollo submersible pumps generally have an excellent reputation. And this device stands out among them thanks to technical solutions that guarantee reliability and a long service life. Its 370-watt motor is capable of operating in S1 mode - that is, without stopping (provided that the pump is immersed in a liquid that cools the engine). Thermal protection is provided (when the motor overheats, automatics turn off the power). High-quality plastic housing, technopolymer impeller and stainless steel drive shaft resist corrosion. The tightness of the structure is ensured by a double mechanical seal with an intermediate oil chamber. The body and “insides” withstand scalding with boiling water without damage (the pump can work briefly in liquids with temperatures up to 90 ° C). Almost the only drawback noticed is a short cable (5 m), which sometimes has to be lengthened if the equipment is placed far from the outlet.

It is important to note that all types of Pedrollo pumping equipment are produced only in Italy (without the participation of Chinese contractors, with whom many other manufacturers cooperate). Therefore, you will not find pumps of this brand among low-cost models. But you can't call them expensive either.

The small Grundfos Unilift KP 150-A-1 drainage pump does an excellent job of pumping contaminated liquid, provided that it does not contain fibrous inclusions, and the particle size does not exceed 10 mm. Therefore, it can pump water from a reservoir (pond, lake or river), a rainfall tank or a well. This pump is also often used to drain basements or other flooded areas. In private households, it can be useful for forced pumping of liquid from biological wastewater treatment plants. The very compact dimensions (149x214 mm) make this unit perfect for installation in narrow pits and wells closed with small diameter covers.

Grundfos drainage pumps have a long service life. Their reliability is due to a well-thought-out design and the use of high-quality materials. At Grundfos Unilift KP 150-A-1, for example, all parts that come into contact with water (body, impeller, drive shaft, etc.) are made of good AISI 304 stainless steel. Therefore, despite constant contact with dirty water, they not afraid of corrosion. The device cools itself with pumped water during operation. The cooling efficiency is so good that the built-in thermal protection almost never trips. Therefore, the pump can work for a long time without stopping, without being in danger of overheating the motor.

This pump, with a capacity of 8.1 m³ / h, is the smallest in its “family”. He has more powerful "brothers": 10.5 m³ / h and 14 m³ / h. But all of them, including the model in question, are quite expensive. Therefore, not everyone can afford to buy Grundfos to drain the basement or pump out the septic tank.
