Benefits of Dab circulation pumps
The main advantages of using Dab pumps are the following technical characteristics:
- energy efficiency class B - with high efficiency, energy consumption in the pumping mechanism is halved;
- insulation class - F;
- corresponds to the level of protection IP 44;
- meets the requirements of European certification - standard EN 60335-2-51;
- the possibility of organizing deliveries under the OEM program.
A significant increase in the level of efficiency in the system can be achieved by installing a circulation pump Dab, which ensures uniform distribution of the heated coolant. Units of this type are capable of continuously distilling liquids with a homogeneous working composition for a long time.
The Dab circulation pump is therefore the ideal pumping equipment for domestic and industrial use for circulating liquid media in open (tanks) as well as pressurized closed heating and air conditioning systems.
The best expensive pumps for heating systems
GRUNDFOS ALPHA2 25-60 180
ALPHA series pump, made in Denmark. A highly efficient device is widely used for the circulation of heat carriers (radiator heating systems, "warm floor" systems). The pump is highly reliable and the three fixed speed modes along with two proportional pressure modes are ready to meet the needs of any customer.
Management is mastered at an intuitive level - just select the only mode out of seven possible. It is connected to the general system using a special plug marked Alpha. If you connect pumps through uninterruptible power supplies, you can significantly increase the operating period of the system due to the fact that it consumes very little energy. Based on the feedback from customers who bought this model, we formed the following advantages:
Large spread of power consumption;
Availability of Alpha plug;
It is not necessary to remove air from the pump;
Reliability. Cons:
High price.
Very simple thermostat for heating
Good day!
Heat regulator
But this is what I discovered this weekend (the boiler was heated for the second time, so there is little experience so far), with a long-term furnace, a balance of temperature is established in the system (batteries, air in the room, water in the direct, return pipes and in the boiler), i.e.according to the algorithm, the pump should turn off, but this cannot be done, the water in the boiler may boil.
Maybe the algorithm needs to be changed and measure the temperature only on a straight pipe, if it is above 25 degrees, turn on the pump, if it is lower, turn it off
In my scheme, I assumed the implementation of the following work logic:
in the initial state, the first indicator shows the temperature on the straight pipe, and the second shows the temperature overboard (on the street, but why is this necessary?)
with buttons
at the 1st press and holding both buttons for 3-4 seconds
switch to the temperature threshold setting mode for
supply pipe (the first indicator flashes, the second indicator lights steadily)
at the 2nd press and holding both buttons for 3-4 seconds
switch to the mode of setting the emergency threshold, (the first indicator flashes, the second indicator is off)
at the 3rd press and holding both buttons for 3-4 seconds
switch to the mode of displaying the temperature at the supply and overboard (both indicators are lit steadily)
Temperature setting is carried out with the same buttons,
presses are fixed in the mode of setting the temperature along the trailing edge, and simultaneous pressing - along the front (with gates in time)
When the temperature on any sensor exceeds the set alarm threshold, 0.5 Hz pulses are sent to PD4. reset by pressing any button
PB2 lights the LED to display the sign "-" at low temperatures
PD3 should work like this
if the temperature of the straight line exceeds the values specified by us. then "1" appears on it if it is less. then "0"
Dear forum users, tell me where and what is wrong
Circulation pump for heating characteristics
Circulation pumps
The heating system in a private or country house needs a special pump that will help the coolant circulate through the pipes. Thanks to such a circulation pump, it is possible to ensure that all rooms in the house are heated in the most uniform way. Installing such a device involves some calculations. Payment heating pump may depend on certain specific circumstances. First, you need to decide on the type of pump. The pump can be "wet" or "dry". Their difference lies in the fact that the working area of the first pump is located under a layer of water, that is, in the pumped medium.
Such a pump does not need additional lubrication or moisturizing. However, it must be taken into account that the water pressure or resistance can greatly affect the functional capacity of the unit. Let's figure out how to calculate the pump for heating.
Submersible pumps
A submersible pump is lowered into a well, well or underground reservoir (be sure to lower it below the water level) and it will begin to pump water (pushing it to the surface). Lifting is carried out using pipes or rubber hoses.
All submersible pumps can be divided into 2 types:
- To work with clean water;
- For work with dirty water.
Now closer to Oasis products
Submersible pumps are divided into:
- Submersible drainage;
- Downhole submersibles.
Submersible drainage is used for pumping water. If there are frequent floods in your area, then these pumps are usually used.
Downhole submersible pumps. This type of pump is used to lift water from a well, but the water must be clean, without impurities.
In addition, additionally, the internal elements of such pumps are made of stainless steel (due to this, the service life is significantly increased).
Submersible pumps Oasis characteristic
Submersible drainage pumps, in turn, are divided into:
Pumps for clean water (there may be small contaminants in the water no larger than 0.5 cm in size).
Characteristics of models for pure water:
- DN 110/6;
- DN 170/9;
- DN 220/14.
Pumps for dirty water (there may be particles no larger than 3 cm in size, and with a total volume of no more than 10% of the total volume of water).
Characteristics of models for dirty water:
- DN 250/10;
- DN 150/6;
- DN 175/7 (in a metal case);
- DN 266/11 (in a metal case).
Victor is 34 years old. I recently bought a submersible pump from Oasis, good quality for an inexpensive pump. So far no complaints.
Olga is 43 years old. My husband bought such a pump, for a year now everything has been working without problems, I was worried that if it was inexpensive, then it was not of high quality, but no, everything is fine.
Igor is 28 years old. Well, in general, I bought such a pump, I have been using it for a week, the impression of the purchase is positive. The water pressure is excellent (for example, 3 m3 is gaining in 20-25 minutes), while it is quiet.
Irina is 30 years old. I persuaded my husband to buy Oasis (my husband wanted a more expensive German manufacturer) and you know ... we don’t regret it, but my husband made a gift with the money saved.
Daniel is 36 years old. Bought it and it works great.
Oleg is 46 years old. I am engaged in the installation of Oases, I installed 5 submersibles this year, the customers are satisfied, there are no problems.
Marina is 31 years old. I bought Oasis, I use it, there are no problems. Recommend.
Valery is 35 years old. I've been using this pump for a couple of years, I'm very impressed for such a relatively low price, but I installed filters and now, as soon as it gets clogged, I change it.
Tolik is 42 years old. Well, what can I say, the quality corresponds to the price, yes it works, but there are some breakdowns that you can fix yourself or contact a service center (it is still under warranty).
Dab Pump Specifications
The circulation pump Dab is widely used in heating systems.
Due to its excellent technical characteristics, the dab pump is widely used in heating and air conditioning systems for residential and industrial purposes. At the same time, other brands of aggregates (for example, Grundfos, Wilo, Wester, Gileks, Unipump, Oasis) proved to be no worse.
The pump of the Italian manufacturer Dab is represented by a single cast-iron casing, inside of which there is a hydraulic unit made of bronze and a motor with a “wet” type rotor. What does a circulation pump mechanism with a "wet" rotor mean? This is a pump with an efficiency level of over 50%, which combines the features of axial and radial impellers.
Additionally, the unit is equipped with a built-in emergency shutdown relay, so the equipment does not require additional overload protection in the system and is considered reliable.
The circulation pump dab for heating can be mounted in hard-to-reach places.
The motor housing itself is made of die-cast aluminum, the impeller is made of technopolymer. The heating pump and the electric motor, in fact, form a single working unit that does not contain shaft seals.
The Dab pump with a 2-pole single-phase asynchronous electric motor is capable of operating in 3 modes, switching between which occurs due to the switch located on the terminal box. The dual pump system has an automatic shutter to prevent situations when unauthorized water recirculation occurs in an idle (off) state.
Important! The Dab pump does not require additional overload protection, as
there is a built-in emergency shutdown relay. In addition, during the operation of the pump, the bearings are lubricated by the pumped liquid.
