Top 10 drainage pump

When your name is Pedrollo, it's not so scary to climb into the mud. The pumps of this company have proven themselves in such work, they are reliable and durable, although not cheap.

In recent fecal pump rating We have already mentioned the weak side of Pedrollo - the use of a thin impeller, limiting the maximum size of the pumped mechanical impurities. Well, as a drainage pump, which first of all will have to deal with eroded silt and sandy suspension, the “Italian” looks much more convincing.

The manufacturer did not save on stainless steel, so the pump can be in the water indefinitely without problems. The impeller is polymer (but with reinforcement), which, in principle, has long become the norm. The seal works in an oil bath, it has no problems with durability.

The engine is a conventional single-phase unit with a power of 600 watts. It provides decent performance: with a maximum lift of 11.5 meters, it pumps 25 liters per minute, all 275 drives to a two-meter height. It can be submerged no more than 5 meters relative to the water level, like most drainage pumps. A float switch can allow the pump to automatically drain almost to the bottom - the minimum height of the intake fluid is 15 mm (!). Provides protection against dry running and overheating. So the pump deservedly earns its place in the ranking of the best drainage pumps.

This drainage pump is designed for high performance, but not for dewatering “to the bottom” - its fence is tall. On the other hand, due to the high impeller, it quietly “digests” fractions up to 50 mm, which is an excellent result for a drainage pump - in fact, although it is not positioned by the manufacturer as such, it can work as a fecal one.

The power of the motor is no less than 1470 watts. This once again underlines its “construction” purpose - in a private house it will already be overkill, the starting current at the motor will noticeably “squander” the network, and with a weak substation the neighbors will tell you “a couple of tender”.

The pump “closes” at a twelve-meter rise, which looks somewhat strange - a far less powerful Grundfos still continues to pump with such pressure. But the peak performance of the Metabo is 460 liters per minute! It would seem nice, but this value is measured at zero height. And let's compare it on the same two meters that we took for the Grundfos AP12 - that one “masters” 300 liters per minute, and Metabo - only 80 liters more. So, if you do not plan to work with large factions, then a much cheaper “Dane” will turn out to be just as good, besides, it will be easier and more economical. Accordingly, the rating and drainage pump Metabo we put is not the best.

The Italian drainage pump manufactured by Speroni S.p.a is designed primarily for work with thoroughly polluted water (particle size is up to 35 mm), therefore it has a thorough intake and a power of 1.1 kW. True, the intake is located a tall, like the other pumps of this type, "dry", he does not pump out, if it is not bury in the "glass".

The quality of materials does not complain - even the pump housing itself, usually cast from cast iron, is also made of stainless steel. Virtually all parts that come into contact with water, except for shaft seals, are made of AISI 304 steel. Excellent! Although expensive.

The lifting height of the pump is not a record holder, its limit is 8 meters. At a height of two meters, it raises 18 cubic meters per hour, so that in terms of the ratio of energy consumption to productivity, it does not look the best. This is the inevitable retribution for the "omnivorous", which requires increasing, among other things, the gaps between the casing and the wheel - the probability of jamming by particles falling between them decreases, but the efficiency decreases.

The German company, now owned by the Swedish Huskvarne, offers not just productive (20,000 in labeling - this is the maximum performance in liters per hour), but also a truly reliable drainage pump: in 2019, the company gives it a 40-month warranty, provided registration of the purchased pump on the site. It “swallows” particles up to 38 millimeters in size, it can dive up to 7 meters, and in addition it is also universal in connection - the corporate universal outlet connection allows working with hoses from two inches to half a inch. So you will not have a pump idle - having pumped out the “extra” water, you can quickly retrain it in a watering room, for example - the benefit of a powerful motor allows it to “press” well. Yes, and his weight is just over 8 kilograms - easy to pull out and move from place to place.

The only thing worth considering is that both the base and the top cover are made of plastic at the pump, so that it is more sensitive to shocks than pure metal pumps.

The CC series in the Grundfos Unilift drainage pump line is the most budgetary because it abandoned the use of stainless steel, replacing it with a composite. The pump casing, the engine casing, and the external casing were made from it. As a result, the pump became light (4.6 kg) and is simply transported elementary without any effort, but its minuses appeared.

It is expectedly more sensitive to solid inclusions in pumped water than the more expensive Unilifts - a pebble inside will damage both the wheel and the inner surface of the pump casing. Be sure to keep this in mind when choosing a pump. Secondly, plastic has worse thermal conductivity, so the main feature of Unilift suffered as well - cooling of the motor with a stream of water. Of course, the 380-watt electric motor is not heated so much, but still ...

This is a powerful enough (1100 W) pump, which is convenient for pumping out water from flooded basements and cellars, wells, and various sizes of water bodies. Moreover, the liquid can be with particles of dirt with a diameter of up to 35 mm. Pumps the unit up to 19 thousand liters per hour (using a 38-mm hose). The maximum height of the water supply is 9 meters, while in the water it can be lowered no deeper than 2 meters. The pump is sensitive to too hot water (its temperature should not exceed +30 degrees) and to voltage drops in the mains.

The classic "country" drainage pump, which is not so expensive, but well assembled. It is designed for a shallow dive (up to 1 meter), but how often do you need a great depth at the dacha? But on 2 meters it raises up to 7 cubic meters per hour, and its “ceiling” is 6 meters (capacity drops to 1 cubic meter), so it can cope with pumping water from the caisson normally.

The case and the impeller are plastic, which is not surprising for the budget model: “the plastic world has won.”However, the pump was successful and economical (power - 320 W), and due to pumping water between the motor housing and the outer casing, it can work for a long time without overheating.

Hmm, it looks like something ... But this is a clone of the old "Makita" - even the Chinese intake form is diligently repeated. The difference is less by almost half the power and a corresponding drop in performance, but the price is also less. And in terms of quality, to be honest, they don’t have any serious difference (there’s not much plus “Eliteku”, but minus “Makite”)

With the “Makita” it is also united by the secrecy of the manufacturer - the hydraulic curve of the pump is also not given, unfortunately.
