Description

Pumping station AL-KO HW 3500 Inox Classic - this station is more suitable for the water supply of relatively small country houses, where the likelihood of turning on all faucets and showers is unlikely. At a pressure of 3 atm (which is standard parameter water supply system), this pump delivers about 14 liters per minute. In fact, these are two simultaneously open taps, or one very good shower. But, if you are satisfied with a pressure of 2.5 atm, then this water supply station is already ready to provide water for 3 taps, or 2 showers simultaneously working. In other words, it is partly a "border pump". A country house with a relatively small water intake is its scope.
In terms of its configuration and capabilities, it is difficult to add anything unique - after all, this is a classic pumping station controlled by a pressure switch. When drawing water, the pressure drops - the pressure switch turns on the pump. There is no protection in this pump, except for the thermal protection of the motor. But, it is worth noting the reliable and durable motors of ALCO pumps. They really last a long time, they are simply very reliable.
By the way, if you need to equip this pumping station with protection against dry running, then we are always ready to suggest a solution to this issue.
In order to reliably operate AL-KO HW 3500 Inox Classic, it is advisable to use it in cases where your well is always full of water, and it is relatively close to ground level.
It is also worth noting that the designers of AL-KO tried to make the pump quiet. To do this, they used in the production of new materials that have noise-reducing properties.
And a few more words about the cases in which it is possible to use this pumping station. The AlCo pumping station takes water from a depth of up to 8 meters. But it’s really worth understanding that the desired applicability of the pump is desirable if the water is no more than 5 meters away. After all, in any case, you will have a large water intake. The water level in the well will inevitably fall, and in extreme cases, it is possible that the house will be left without water.
Also, it is worth taking into account seasonal fluctuations in water, possible dry months when the water level drops naturally.
The pumps are manufactured in China. But that doesn't make them worse. In this case, they are simply more affordable than European made pumps. And in confirmation of this, the manufacturer gives a 3-year warranty, supported by an official service center.

ALKO is a German group of companies engaged in the production of pumping equipment for domestic and industrial use, as well as climate technology. The company has been present on the market for over 50 years, during which it has established itself as one of the leaders in its industry.

In this article, we will consider ALKO pumping stations, study their device and principle of operation, get acquainted with model range equipment and provide recommendations for its operation, adjustment and repair.

1 What do ALCO pumping stations consist of and how do they work?

The design of German stations for autonomous water supply consists of two main elements - a pump and a hydraulic accumulator, additional nodes are a pressure gauge, a pressure switch and a dry running sensor. Consider the functional purpose of each part of the pumping station:

1. Pump - lifts water from a well or well and pumps it to the point of consumption. All, without exception, stations are equipped with surface centrifugal pumps. Each time such equipment is started, it is necessary to fill the compartment inside the pump housing with water, for which a special filling hole is provided on it.
2. A hydraulic accumulator is a reservoir for storing a reserve volume of water, which reduces the number of pump starts (thereby extending its operating life) and protects the entire system from hydraulic shocks. The standard volume of hydraulic tanks from ALCO is 25-50 liters, depending on the model of equipment.
3. Pressure switch - allows the station to operate in automatic mode, turning on the pump when the pressure in the hydraulic tank drops below a predetermined level (which indicates the absence of water in the tank) and turning it off when filling with water.
4. Dry running sensor - turns off the pump in case of idling, preventing overheating and engine failure.

A distinctive feature of ALCO stations from analogues is the presence of built-in coarse filters, which are located on the inlet pipe of the pump. Complete filters are replaceable, they need to be changed as they wear out - every 4-6 months, depending on the purity of the pumped water.

The range of equipment of the German company, depending on the performance, can be divided into 3 classes of stations:

• up to 3100 l/h;
• up to 4000 l/h;
• up to 6000 l/h.

2 Model range of equipment

ALCO manufactures and supplies to the market over 40 models of pumping stations, the most popular of which are:

• HW 3500 Inox Classic;
• HW 1300 Inox Classic;
• HW 4000 FCS Comfort;
• HW 800 and 802 Inox;
• HW 3000 Inox Classic;
• HFW 1000.

The Inox marking indicates that the pump housing and hydraulic tank are made of corrosion-resistant stainless steel. Note that the pumping stations HW 800 and HW 802 are currently out of sale, they have been replaced by a more powerful analogue HW 1300. This equipment can only be found in the secondary market.

One of the most affordable options is the AL-KO HW 3000 Classic automatic pumping station, the cost of which is 8 thousand rubles. This unit is ideal for a home or cottage where a family of 3-4 people lives.

Pumping station AL-KO HW 3000 has the following technical characteristics:

• hydraulic tank volume - 17 l;
• power - 650 W;
• suction height - 8 m, feed - 28 m;
• productivity — 3100 l/hour.

Among the operational advantages of this model, we highlight the low level of noise and vibration during operation, the compact dimensions of the case and the presence of a system for protecting the electric drive from overheating. A more powerful version is the older model Inox HW 3500, in which the drive power is increased to 850 W, and the water supply depth is up to 38 m. The supply volume has also increased to 3400 l / h.

HW 4000 FCS Comfort

In the segment of high-capacity pumping stations, attention should be paid to the HW 4000 FCS Comfort model, which is sold at a price of 19 thousand rubles. This unit is equipped with an XXL standard coarse filter, which allows the pump to be used for pumping contaminated liquids.

HW 4000 FCS is equipped with all the necessary automation, there is a pressure switch, dry running protection and an engine shutdown system in case of overheating. The unit pumps up to 4000 l/h and has a maximum suction/delivery height of 8/35 m respectively.

The best choice for watering gardens and household plots would be the HWF-1000 surface pumping station, the cost of which is 14-15 thousand. The model is equipped with a 24-liter hydraulic tank, while it has a minimum weight of 14 kg, which allows you to conveniently move the station within the suburban area .

Specifications of HWF-1000:

• power 800 W;
• suction height - 9 m, feed - 28 m;
• productivity — 3600 l/hour.

According to user reviews, the working life of the HWF-1000 model is 3-4 years before the first major overhaul.

2.1 Features of setting up and repairing the National Assembly

After putting the pumping station into operation, you may encounter the fact that the pump automation does not work as it should. The problem is an incorrectly configured pressure switch. From the factory, the stations are calibrated to a cut-off pressure of 2.5 bar and turn-on pressure of 1.5 bar. If you purchased the unit as an assembly, then most likely no adjustment is required, however, if separate components were purchased for subsequent assembly, then you will have to configure them yourself.

The relay diagram is shown in the image, where you can see two clamp nuts. The smaller one is responsible for the upper pressure limit at which the station is turned off, the larger one is for the switch-on pressure. The adjustment of the relay begins with the emptying of the hydraulic tank, after which it is necessary to check the air pressure using the pressure gauge built into the tank. If the sensor is missing, then you can use a conventional car pressure gauge by attaching it to the accumulator nipple. If the actual level of air pressure does not match the required one, we pump air with a pump.

When setting the pressure switch, keep in mind that the upper limit cannot be increased above the maximum allowable working pressure level of the hydraulic tank (water + air). To increase the switching pressure, turn the small nut clockwise, to decrease it counterclockwise.

ALCO provides a one-year warranty for its products. In general, the stations are quite reliable and durable, but no equipment is immune from breakdowns. Equipment repairs are most often performed due to the following faults:

• water is not pumped when the pump is running - you need to check the tightness of the intake hose and the integrity of the check valve;
• the pump pumps jerkily - the problem is the tightness of the accumulator housing or the deformation of the membrane located in it;
• the working pressure is reduced - the pump impeller is deformed, which cannot be replaced by one's own hands, the services of a service center will be required;
• the pump does not turn on - the cause is burnt capacitors or a damaged motor winding.

It should be noted that ALCO pumping equipment is widespread in Russia and, if necessary, you can easily purchase the necessary components.

I purchased this "miracle" on 01/04/15. To replace it, it was exactly the same, but with a plastic pump cover that burst and leaked. The service said "It happens quite often, but the case is not guaranteed." By April 20, she began to work so that two floors in the house were shaking from the roar. drove to service center, it seems like an almost new "guarantee" MUST be! It turned out that the oil seal was leaking and two bearings fell out. They explained that the case is not guaranteed, the warranty applies only to the electrical part and only to the short circuit of the motor winding and ONLY if this did not happen due to leakage. In other words, this is g ... but, which has been working for 3 months and the manufacturer knows this, therefore the guarantee is only an advertising ploy!
