Drainage pumps Vilo from the manufacturer Drain in an automated mode pump out contaminated water, and are also used for drainage purposes. They are able to perform many functions in suburban and private homes. It is necessary to correctly select the units for work, given the technical limitations.
Principle of operation and arrangement of Wilo drainage pumps
The lineup is represented by several lines, each of which is designed for specific purposes and has individual technical characteristics.
The main field of application of Drain pumps is the removal of water from pits during the drainage of underground structures, houses and mines, for pumping liquids from flooded basements, ponds and various containers. All units are divided into two main groups:
- submersible;
- superficial.
The former, due to immersion in water, have compact dimensions in comparison with surface bulk units. They emit less noise, and also have a more powerful head. However, submersible drainage pumps have two significant drawbacks:
- the case must remain airtight, due to the work in a humid environment, which complicates the repair process if necessary;
- in case of breakdowns, the units must be removed from the water.
They make equipment from an innovative high-quality alloy, it includes chromium, chromium-nickel, chromium-nickel-molybdenum steel, as well as additives of niobium, titanium and copper.
Principle of operation
The processed liquid at the initial stage of pumping enters the working chamber. Under the influence of pressure from the impellers, it tends to the outlet pipe.
The pumped liquid also cools the engine, since it passes near it in a special hole in the housing. To exclude the possibility of overheating, the units have limitations on the temperature of the medium. As a rule, the liquid should not be hotter than 50 degrees.
Lineup and Specifications
Among the models there are exhibits designed for pumping hot water, aggressive liquids, and condensate. The maximum allowable temperature of liquids is not more than 95 degrees.
A separate model range is designed for pumping wastewater with feces, as well as drains from household appliances.
Certain modifications of drainage pumps can be used in small waterfalls and fountains. In this field of application, submersible drainage pumps are mainly used. With the exception of the Drain LPC and LP models, all units are submersible.
The most popular Wilo drainage pumps include:
- WILO DRAIN TMT 32H102 / 7,5CI - submersible unit of the vertical installation type, which is capable of pumping liquid up to 95 degrees. The equipment is quite compact, its weight is 30 kg at a height of 45.5 cm, it has an IP68 moisture protection class. The engine power is 750 watts, per minute it carries out 2870 revolutions. It is able to pump out drains at a pressure of 13 m. Permissible immersion depth 10 m.
- WILO DRAIN VC 32 AND 40 - the unit is designed for high temperature water, as well as some aggressive compounds with permissible particle sizes of not more than 8 mm. The unit operates in an upright position, equipped with a built-in thermal relay and stand. It has a moisture protection class of IP54, pressure reaches 20 m, flow rate 14 cubic meters / hour. In a minute both engines carry out 2900 turns.
- WILO DRAIN LPC is one of the representatives of self-priming drainage units, which are designed to pump dirty liquid from ponds and pits.The main scope is the irrigation of suburban areas, as well as the organization of water drainage for treatment and filtration. It can be used for pumping liquids with a maximum temperature of 80 degrees, the size of solid impurities should not exceed 12 mm. Users note ease of use and high structural strength. The moisture protection class is IP55.
- WILO DRAIN TC 40 is a submersible household unit designed to drain dirty liquids from sewage treatment plants and sewers. Protection class IP68 with insulation class F is installed, the casing is made of high-quality cast iron with a built-in float, which automatically shuts down the unit. Permissible water temperatures range from 3-40 degrees, the size of solid impurities should not exceed 4 cm. Engine power 600 W, per minute it carries out 2900 revolutions.
Prices for Vilo drainage pumps for different types of liquids are different. It all depends on the components and technical capabilities of the unit. The average cost in Russia starts from 16,000 rubles and reaches 85,000-90000 rubles.
Installation of equipment
Installing drainage equipment is straightforward. To avoid difficulties, you need to familiarize yourself with the algorithm:
- Check for completeness and carefully read the attached instructions for use.
- Install the equipment in an upright position and connect the line to the discharge pipe.
- Connect the drain pump to the mains and make a flow measurement.
- Turn off the device, replace the phase and repeat the previous step.
- Compare feed rates and choose the right one.
The equipment should work in a vertical position, the discharge pipe should be directed upwards.
Criterias of choice
When buying, you need to rely on the following criteria for the correct choice of submersible equipment:
- pumped liquid characteristic;
- diameter of outlet nozzles;
- materials used in the manufacture;
- unit head for pumping liquid and type of circuit breaker.
Vilo drainage pumps are produced by a well-known and popular German brand, therefore, fraud cases when selling fakes of dubious quality are common. It is important to familiarize yourself with all attached documents and a warranty card.
