A pumping station is a mandatory attribute of an autonomous water supply system for a private house. Italian marina aggregates are very popular among masters. The equipment is characterized by high performance and affordable price. In addition, spare parts for the Marina pumping station are always available in case of repair. Although such situations arise extremely rarely.
The device and principle of operation
All Italian units, regardless of their model, have similar devices. For each, the following work units are provided:
- hydroaccumulator, it is also an accumulative membrane tank;
- a centrifugal pump with a built-in ejector, if you need a more efficient unit, the ejector is made portable;
- pressure switch and pressure gauge to control it;
- water temperature sensor.
Additionally, all Marina stations are equipped with a check valve. This prevents the outflow of water from the tank.
The Italian pumping equipment works according to this principle:
- using a thin ejector tube, the pump fills the storage tank;
- at this moment, the pressure in the system rises as much as possible;
- when you open one or more taps in the house, water begins to leave the accumulator;
- due to the outflow of liquid, the pressure in the pumping station Marina drops;
- at these indicators, the pump again starts up and starts pumping water into the tank until the pressure rises.
Station operation cycles are repeated continuously. This ensures that constant pressure is maintained in the autonomous water supply system.
Lineup and Specifications
Italian units are available on the market in several versions. In total there are four series of pumping equipment:
- The CAM line. This is the most budget option. The case is made of cast iron or stainless steel. Centrifugal pump blades - made of durable polymer. The maximum depth of water intake is 9 m. Several models of stations are presented in the CAM line of units, the power of which varies in the range from 0.8 to 1.7 kW. Storage tank - 22, 25 or 60 liters. The maximum pressure ranges from 43 to 60 m. The productivity of the Marina SAM stations is from 3.5 m3 / hour to 4.2 m3 / hour. The most popular models of this series are Marina Cam 80/22, 60/25; 100/25; 40/22.
- AWP series. More powerful, heavy and productive units designed to lift water from a depth of up to 50 m. The body of these stations is made of stainless steel. The most popular models from the AWP series are 100/25 and 200/25. The approximate weight of the equipment is 35 kg. The power of the units is from 1100 to 1500 watts.
- Series Marina K. S. They have a polymer body, which reduces their weight to 14 kg. Power from 800 to 1300 watts. Productivity is from 3600 to 4300 l / h. Pressure - 42-50 m.
- A line of RSM stations. Head from 32 to 60 m. Maximum suction depth up to 7 m. Productivity - about 6 m3 / hour. Power - 1400 watts.
Allocate Marina models with the electronic regulator "Idromat". Stations, according to the instructions, are created on the basis of CAM, RSM or KS pumps. Dimensions are minimal. Tuning Idromat models is highly accurate. Units are available in two versions - with tanks of 25 and 100 liters. Power - 1400 watts. Head - 50 m. Depth of fluid intake - up to 7 m.
Criterias of choice
Choose the Marina station by the following parameters:
- Case material. The durability of the unit under different operating conditions depends on it. If it is intended to use the station in the field, it is better to take equipment in a steel or cast-iron case. To install equipment in an insulated basement, polymer is also suitable.
- The volume of the storage tank.It is calculated by the number of family members. For two or three people, a hydraulic accumulator of 25-40 liters is enough. The more people living in the house, the more spacious the tank volume should be.
- Power station. To perform numerous tasks - watering, supplying water to all the taps of the house - you need to take more productive equipment.
- Permissible suction depth. It is calculated by the length of the distance from the point of water intake to the place of its supply (taps).
If it is supposed to supply fluid from very deep wells, it is better to take a unit with a remote ejector. Additionally, attention should be paid to various protection systems - from overheating, dry running, etc.
Features of operation and maintenance
Italian water supply units do not need special maintenance. Stations are sold ready for installation, connection and operation. It is important to initially mount the unit on a specially prepared level surface. It is advisable to put the equipment as close as possible to the point of water intake. You can arrange a specially insulated caisson for the unit.
The equipment does not require lubrication. An exception is the seasonal operation of the station. If you use the equipment only in the summer, the installation should be removed for the winter. Previously, all water is drained from it, the work units are lubricated. Store in a dry, moderately warm place.
If for some reason the Marina station is out of order, it is advisable to contact a service center for troubleshooting. Otherwise, Italian technology works like a well-functioning mechanism.
Advantages and disadvantages
Italian pumping units have a number of competitive advantages over other similar units:
- European build quality. All stations are collected exclusively in Italy.
- Warranty from the manufacturer 3-4 years.
- Economical power consumption.
- The minimum noise level in work.
- The presence of a variety of protection systems.
- The installation of equipment that is understandable even to a novice master.
However, some masters identified a flaw in Italian technology. Such is considered the inability of the Marina stations to pump water with the inclusion of small-fraction garbage. Equipment from Italy is intended only for pumping clean water.
To protect the Marina units from failure due to debris entering the system, it is advisable to immediately install coarse filters on the inlet hose.
Prices for Italian pumping equipment range from 4700 to 22000 rubles. The cost depends on the technical characteristics of each model: power, depth of water intake, pressure, body material, tank volume, the presence of additional systems and options.
Reviews and recommendations
Judging by user reviews, pumping units from Italy justify the money spent on them.
Maxim, 44 years old. My cottage is somewhat on a hill from the rest of the houses in the village. Nearby there is a good pond, so I bought for irrigation of the garden and the garden the Marina station from the CAM series (on the advice of Kuma). The unit was installed in an equipped caisson with a depth of 80 cm. The pump pumps water properly. And even with continuous two to three hours of work, it shows no signs of fatigue. The pressure is good. When mounting on the inlet hose, a coarse filter was immediately installed. The station has been operating for the third summer. No complaints.
Sasha, 42 years old. I bought the Italian station Marina two years ago for a country house. I took a model from the AWP 100/25 series. For a family of 3 people is enough. I did the installation myself, even though I hadn’t done anything like it before. Everything is simple there. The main thing is to immediately pump water into the system. Station management is simple. For two years, never let down. How to set the working pressure, and it works.
