Electric Submersible Pumps Annovi Reverberi

Annovi Reverberi electric submersible pumps are designed for draining and transferring water in domestic environments, gardens and small maintenance jobs. The brand was founded in Modena in 1958 by Corrado Reverberi and Umberto Annovi, initially operating in the agricultural and industrial sectors. From the 1960s, the company began its international expansion; in the 1990s, it extended its expertise to the cleaning sector, also developing pressure washers and vacuum cleaners. The AR Blue Clean range dedicated to submersible pumps includes compact solutions for emptying swimming pools, tanks, wells, ponds, small lakes and flooded rooms. The choice depends on the quality of the liquid, the presence of debris and the required hydraulic performance. At AgriEuro, the range is divided into three types, suitable for clean water, water containing impurities or both conditions.

The available types make it possible to select a pump suited to the operating context:

• Annovi Reverberi submersible pumps for clean water: they operate with clean water or water without significant solid particles, such as water from swimming pools, tanks and reservoirs. They are suitable for water transfer, drainage and small irrigation tasks within the limits specified for each model;
• Annovi Reverberi submersible pumps for dirty water: they are designed for turbid water containing suspended particles compatible with the stated solid passage capacity. They are used in sumps, ponds, small excavations and flooded rooms where soil or debris may be present;
• Annovi Reverberi submersible pumps for clean + dirty water: they combine two operating modes in a single machine for clean liquids or liquids containing impurities. They are suitable for variable environments such as cellars, tanks, ponds and small construction sites, provided that the liquid complies with the model's technical limits;

At AgriEuro, you can select Annovi Reverberi submersible pumps according to their main technical features, allowing you to choose the product best suited to the type of water, the volume to be moved and the discharge point. The comparison should start from the actual working conditions and the data provided in the technical specifications of each model.

• Water type and solid passage: suitability for clean, dirty or mixed water indicates the type of liquid permitted. The maximum particle diameter specifies the size limit of debris that can pass through the pump without clogging its internal passages;
• Power consumption and power supply: power expressed in watts describes the electrical motor's power consumption. Mains-powered models are suitable for repeated operations near a properly protected power outlet;
• Maximum hourly flow rate: this indicates the theoretical volume of water that can be transferred per unit of time. The actual flow rate decreases as the head, pipe length and pressure losses increase;
• Maximum head: this indicates the maximum height to which the pump can push water. This value must be considered together with the performance curve, since flow rate and head vary during operation;
• Immersion depth and minimum residual water level: the former defines the installation limit below the water level. The minimum residual level indicates how much water may remain on the bottom after drainage under the specified conditions;
• Float switch and delivery connection: the float switch can control automatic starting and stopping according to the liquid level. The connection must be compatible with the hose diameter, minimising restrictions and unstable connections;

Hobby and semi-pro levels are designed for different frequencies and workloads. Hobby models are suitable for occasional emptying of swimming pools or cellars; semi-pro models are intended for more regular operations and larger volumes of water, always within their rated specifications.

The range includes pumps dedicated to clean water, models for dirty water and combined solutions. Each family is designed for a different level of particle content and specific drainage requirements. Choosing the right pump reduces the risk of clogging, reduced flow rates and uses that are incompatible with the machine.

Annovi Reverberi submersible pumps for clean water operate with clean liquids or liquids containing very limited impurities, in compliance with the particle size permitted by the model. They are suitable for emptying swimming pools, basins, reservoirs and tanks, as well as for transferring collected rainwater. Bottom suction facilitates drainage close to the bottom; the final residual water level depends on the design of the base and the minimum suction level. The flow rate should be assessed in relation to the volume to be removed, but must also be compared with the required head. A long, narrow hose or one with numerous bends can reduce the actual flow. The float switch is useful for automatic operation because it controls the motor as the water level changes. These pumps are not intended for mud, gravel or debris exceeding the specified limit: checking the liquid beforehand protects the impeller and internal passages.

The most important operating aspects for this type are:

• Compatible water: the liquid must be clean or contain particles within the permitted limit. Water containing soil, leaves or significant sediment requires a dirty-water pump;
• Drainage close to the bottom: some models reduce residual water thanks to the configuration of their base. The actual value should be checked in the technical specifications and depends on stable positioning;
• Typical uses: swimming pools, tanks, reservoirs and rainwater collection systems are suitable applications for this family. For wells and greater depths, the available immersion depth and head must be carefully checked;

Annovi Reverberi submersible pumps for dirty water are designed for turbid water containing impurities and small suspended solids. The hydraulic structure provides wider passages than clean-water versions, but each unit has a maximum permissible particle diameter. This feature makes them suitable for draining sumps, ponds, flooded rooms and small excavations containing compatible debris. They should not be confused with pumps for sewage, black water or aggressive fluids unless specifically indicated by the manufacturer. Flow rate and head remain the key parameters for estimating emptying times and the achievable height difference. The float switch can automate cycles when it has enough space to move freely. After use, it is advisable to rinse the base, grille and impeller area with clean water. This helps prevent deposits that could hinder subsequent start-up.

When choosing a dirty-water pump, the following elements should be considered:

• Size of impurities: the solid passage capacity must exceed the actual particle size present in the liquid. Fibrous materials, stones or dense sediments may require specific equipment not included in this family;
• Space for the float switch: the sensor must be able to move without hitting walls, pipes or debris. Restricted movement may prevent the pump from starting or leave it running when the water level is too low;
• Cleaning after drainage: thorough rinsing removes light mud and debris from the passages. Before storage, it is also advisable to check the cable, connection and suction grille;

Annovi Reverberi submersible pumps for clean + dirty water are multifunction models designed for conditions that may change from one job to another. A base configuration or specific adjustment system allows the pump to switch from draining clean water to pumping liquids containing permitted debris. In clean-water mode, the aim is often to leave a reduced residual water level on the bottom. In dirty-water mode, however, the internal passage is configured for larger particles. The dual function is useful in cellars, tanks, ponds and small construction sites where water quality is not constant. Before starting, the machine must be configured correctly and the particle size, depth, head and delivery hose must be checked. A combined model expands the range of possible applications, but does not replace a dedicated pump for heavy sludge, sewage or prohibited substances.

The main operational advantages of combined models are:

• Dual mode: the same pump can operate with clean water or water containing compatible impurities. The configuration specified by the manufacturer must be set before each operation;
• Adaptation to variable conditions: the multifunction model is practical when water quality changes due to rainfall, deposits or bottom conditions. The stated limits for permitted solids and liquids still apply;
• Reduced equipment requirements: a single machine can cover several domestic or semi-professional drainage tasks. Its convenience depends on the frequency of use and the compatibility of its performance with both scenarios;

The main difference concerns the quantity and size of permitted impurities. A clean-water pump operates with clean liquids or liquids almost free of particles; a dirty-water pump has passages designed for suspended solids up to a specified diameter. The maximum particle size must therefore be compared with the sediment, leaves and debris present at the intake point.

The selection starts with the type of water, followed by flow rate, head, immersion depth and maximum solid diameter. You should also check the desired minimum residual water level, the free space available for the float switch and the connection size. All parameters must comply with the model's technical specifications, because motor power alone does not describe its complete hydraulic performance.

The flow rate indicates the volume of water the pump transfers over a given period of time; the head indicates the height to which the liquid can be pushed. Maximum values do not occur simultaneously: as the height difference and pipe losses increase, the available flow rate decreases. For an accurate assessment, consult the model's performance curve.

The maximum solid passage establishes the maximum particle size compatible with the pump. Larger debris may block the impeller, clog the grille or accelerate component wear. The term “dirty water” therefore does not mean that any material can be pumped: dense mud, stones, fibres and sewage require specifically suitable equipment.

A pump for clean and dirty water is suitable when the liquid changes between different tasks or according to environmental conditions. It can be used, for example, for a tank containing clean water and for a flooded room containing small debris. Before each operation, the specified configuration must be selected and the limits regarding particles, depth and head must be respected.

The float switch automatically controls switching on or off according to the water level. It must have enough space to rise and fall without hitting walls, pipes or debris. Correct adjustment helps keep the level above the specified minimum threshold, but does not replace the checks described in the product manual.

In general, a submersible pump must not run dry, unless explicitly stated otherwise in the technical specifications. Lack of water can damage the seal and motor because the liquid contributes to cooling the system. The minimum level, float switch position and manual or automatic operating mode must always comply with the instruction manual.

The minimum residual water level is the level that may remain on the bottom after drainage under the conditions specified by the manufacturer. A low value is useful for swimming pools, floors and basins that need to be emptied almost completely. The actual result also depends on the flatness of the bottom, the position of the pump and any clean-water setting.

The delivery hose must be compatible with the pump connection and have a diameter suitable for the required flow rate. A cross-section that is too small, excessive length and numerous bends increase pressure losses, reducing the available flow. Clamps, couplings and the discharge point must also be stable and comply with the model's specifications.

Routine maintenance includes rinsing the pump, removing deposits from the grille and checking the float switch. Before carrying out any inspection, disconnect the power supply and follow the manual. The cable, connections and internal passages should be inspected periodically; the machine should then be dried and stored under the conditions specified by the manufacturer.
