Drainage pumps Vilo from the manufacturer Drain automatically pump out contaminated water and are also used for drainage purposes. They are capable of performing many functions in country and private homes. It is necessary to correctly select the units for work, taking into account the technical limitations.
The principle of operation and design of the Vilo drainage pumps
The lineup is represented by several lines, each of which is designed for specific purposes and has individual technical characteristics.
The main area of application of Drain pumps is to drain water from pits during the drainage of underground structures, houses and mines, to pump out liquids from flooded basements, reservoirs 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 volumetric aggregates. They make less noise and also have a more powerful head. However, submersible drainage pumps have two significant disadvantages:
- the body must remain sealed, due to operation in a humid environment, which complicates the repair process if necessary;
- in case of breakdowns, the units must be removed from the water.
The equipment is made of an innovative high quality alloy, which 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 action of pressure from the impellers, it tends to the outlet pipe.
The pumped-out liquid also cools the engine, as it passes near it in a special hole in the housing. To eliminate the possibility of overheating, the units are limited by the temperature of the working environment. As a rule, the liquid should not be hotter than 50 degrees.
Model range and technical characteristics
Among the models there are exhibits designed for pumping hot water, liquids with an aggressive composition, condensate. The maximum permissible temperature of liquids is not more than 95 degrees.
A separate range is designed for pumping waste water with faeces, as well as wastewater from household appliances.
Certain modifications of drainage pumps can be used in small waterfalls and fountains. Submersible drainage pumps are mainly used in this area of application. With the exception of the Drain LPC and LP models, all units are submersible.
The most popular Vilo drainage pumps include:
- WILO DRAIN TMT 32H102 / 7,5CI is a vertical submersible unit capable of pumping liquid with temperatures up to 95 degrees. The equipment is quite compact, its weight is 30 kg with a height of 45.5 cm, it has an IP68 moisture protection class. The engine has a power of 750 watts, it makes 2870 revolutions per minute. Able to pump out wastewater at a head of 13 m. The permissible immersion depth is 10 m.
- WILO DRAIN VC 32 AND 40 - the unit is designed for high temperature water, as well as some aggressive compounds with a permissible size of solid particles no more than 8 mm. The unit works in an upright position and is equipped with a built-in thermostat and a stand. It has a class of protection against moisture IP54, the head reaches 20 m, the flow rate is 14 cubic meters / hour. Both engines rotate at 2900 rpm per minute.
- WILO DRAIN LPC is one of the representatives of self-priming drainage units, which are designed to pump out dirty liquid from reservoirs and pits. The main field of application is irrigation of suburban areas, as well as the organization of water drainage for purification 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 the 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 sewerage systems. Installed with protection class IP68 with class F insulation, the casing is made of high quality cast iron with a built-in float that automatically shuts down the unit. Permissible water temperatures range from 3-40 degrees, the size of solid impurities should not exceed 4 cm. The engine power is 600 W, it carries out 2900 revolutions per minute.
The prices for Vilo drainage pumps for different types of liquids differ. 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
Installation of drainage equipment is straightforward. To avoid difficulties, you need to familiarize yourself with the algorithm:
- Check the contents and carefully study the enclosed instructions for use.
- Place the equipment in an upright position and connect a line to the discharge connection.
- Connect the drain pump to the mains and measure the flow.
- Disconnect the device, change the phase and repeat the previous step.
- Compare the feed rates and choose the correct one.
The equipment must be operated in an upright position with the discharge port facing upwards.
Criterias of choice
When buying, you need to rely on the following criteria for the correct choice of submersible equipment:
- characteristics of the pumped-out liquid;
- diameter of outlet pipes;
- materials used in the manufacture;
- the head of the pumping unit and the type of circuit breaker.
The Vilo drainage pumps are produced by a well-known and popular German brand, so fraud is common when fakes of dubious quality are sold. It is important to familiarize yourself with all accompanying documents and the warranty card.
