Overview of 11 types of best surface pumps: how to select the rating, pros and cons

The use of surface pumps due to the expansion of individual building. The issue of water supply reliably solved with the use of surface water stations.

How to choose a surface pump

Important parameters:

• lifting of a liquid depth. This indicator measures the possibility of using the device. Measured distance from the water surface to the suction pipe.
• The developed pressure. The indicator indicates a permissible range of the transmission fluid. It takes into account the length of pipe irrigation system or water supply.
• Engine power. Indirectly affect these two indicators.

  With the increase in power increases the depth and pressure rise. Not always to be trusted model that with modest values ​​of the motor in kW promise an excellent performance.

Do not forget also about the energy consumption.

• Material. High-quality components (blades, bearings) will save the operation and withstand intense working conditions.
• Noise at work. This figure does not take into account only when the possible isolation of the working design.
• Security. The group includes such design features as integrity, ease of installation works, the build quality.
• Service maintenance. The lack of a service center in the region, creates certain difficulties with the purchase of spare parts and warranty repairs. It is not always possible to buy items from the seller.

Secondary parameters:

When choosing a model will not have much impact factors:

• Well-known brands. Not necessary to overpay for a famous name. The segment highlighted several well-known brands, but also new companies established themselves well.

Along with the well-known model Pedrollo actively sold Ombigena models, domestic pumps.

• Price. Selection is made on the machine characteristics balance.
• Automatic assistants. At periodic monitoring capabilities of the device need to pay is not always justified.

Advantages and disadvantages

The surface unit is designed for lifting water from a public source. An additional area of ​​use is considered pumping water from basements and pits during construction.
Main characteristics:

Among the surface characteristics of the pump is isolated water lifting height. This figure stands at 7-8 meters, depending on the version.

Lifting height is determined by taking into account the proportion of "vertical-horizontal". The optimal ratio is the ratio when lifting meter water is discharged at a distance of 4 meters.

When buying a pump pay attention to the pressure generated. This rate depends upon the design, efficiency, and the installed capacity.
Features and benefits:

• simple structure;
• ease of installation works;
• created by high pressure;
• small size;
• high reliability combined with long life;

2. The quality of the pumped liquid. This characteristic depends on the type of water source, the degree of contamination.
3. Lifting height. This index ranges from 5 to 10 meters.
4. The developed pressure. This characteristic ensures a range of delivery of water to affect the fineness of the liquid spray.

In practice, use of two types of device design - reciprocating and centrifugal.

Advantages:

• provide high pressure at a constant flow rate;
• equally effective in continuous operation.

Disadvantages:

When choosing a model takes into account:

• the presence of the start pressure setting functions and stopping the pump;
• matching supply capacity and pressure to install equipment.

Convenient kits stations Matched Pairs "pump-capacity" presented under the trademark Jumbo 60/35 with polypropylene, the iron and steel container.

Frequent selection of water leads to the regular inclusion of a booster device. This work has an impact on the technical condition and durability of all equipment.

Work in the water system associated with some features:

1. Maintaining the pressure in the pipe at a constant level.
2. The sharp change in pressure in the network by pumping, which is associated with pressure surges.

3. Device with "dry" rotor WILO VeroTwin index DR-E operates with a liquid temperature up to 120 ° C at high pressure (16 bar).

For pumping of hot water use so-called circulators. A closed loop is required for hot water supply and heating systems.

The basic requirement to detail the device - resistance to temperature fluctuations. Therefore, many assembly units are made of cast iron, and the insulation elements - ceramic or special elastic materials.

Fitting with a "wet" method of cooling a rotor different constituent parts. Here cooler performs very moving liquid.

Progressive circuit with "dry" power insulated rotor differs from the movable part of the pressure mechanism. This design is more expensive.

Depending on the working conditions as working machines are the pumping stations of various types:

• possibility to provide water or big house portion;
• the availability of protection and control of the devices.

Disadvantages:

Powerful products are characterized by high power consumption and require more precise placement, keeping on mounting requirements, maintenance.

Top surface station with an ejector

Rating:

1. Calpeda NGXM 3 pumping fluid from a depth of 9.5 m.
2. Machine with external ejector - Pedrolo JDWm 2/30 It creates a pressure up to 81 m, and the lift height is 45 m.
3. Unit Unipump DP 750 It has a lifting height of 20 m, and the pressure - up to 40 m.

For systems running on the surface, is characterized by low depth of water intake. This figure is rarely more than 8-9 meters. In order to lift water from greater depths use the ejector. This device can be of two types:

• integrated device;
• external ejector.

Operation is based on the ejector recirculation liquid. Part of the water is returned during the ascent through a narrow nozzle.

When injected into the mixer is a cavity with underpressure, which causes water from the source of low pressure to rise from the suction chamber into the feed tube.

Using the embedded ejector apparatus allows to increase the depth of suction to a value of 3-5 meters, and a callout helps to lift water from depths of 30-50 meters. In the second case construction is somewhat more complicated.

Advantages:

• working with partially contaminated liquids;
• do not respond to the presence of air is sucked into the water.

An additional advantage of an external ejector called low noise operation.

Disadvantages:

A common disadvantage of designs of any kind is low efficiency, because of the energy is spent on supporting the work.

Devices with built-in fluid return structure creates additional noise when turned on and require a separate room.

The best self-priming pumps surface

Rating:

1. Model Grundfus JP. Lifting height - 8 m, and the pressure - up to 48.
2. The car Wili PB-201 EA. Raises water with 8 m, and the supply range of - 35 m.
3. Model Pedrollo CKM 50 differs from the previous machine large volume pumped water - up to 2.4 m³/час.

All lifting devices start lifting the liquid after the preliminary filling of the suction pipe. The effect of self-absorption is achieved in the process of further work.

On a design units are divided into two types:

• Centrifugal apparatus: single- or multistage without ejector;
• ejector centrifugal pumps.

Scope includes such areas:

• provision of homes and other buildings with water;
• watering section, providing irrigation systems;
• filling pools;
• fluid pumping.

without ejector pumps have a maximum height of 10 meters fluid intake.

The pressure range depends on the motor power. Aggregates with ejectors have a greater depth of the intake: when embedded design - 3-5 m, and length in remote assistant increases by 45-50 meters.

Advantages:

• simplicity and reliability of the design;
• low noise levels;
• does not depend on the nature of the liquid;
• minimum maintenance costs.

Disadvantages:

The weak point of the representatives of the group called the low lift height. The problem is solved by using an external or the ejector pump unit on immersion model replacement.
