Basic 25-8SBGoods Stock:
11. Circulation of liquid in cooling and air-conditioning systems
2. Basic circulator pumps for cold and hot water circulation in heating and air conditioning systems.
3. The pump involves three rotational frequencies that allow selecting the best performance for a certain hydraulic system.
4. Pumps can also be used in single pipe or double pipe heating system, also can be applied to city apartments, suburb villa, cooling, air-conditioning, boilers and solar systems etc.
5. Floor Heating systems
6. Circulation of domestic hot water
Basic circulation pumps designed and produced by our specialists have these features: low noise, no leakage, ecological satety in operation, artistic appearance, easy installation and reliable operation.
Construction
Basic pumps are of the canned rotor type, i.e. the pump and motor form a single unit without shaft seal. This unit requires only two sealing rings and the bearings are lubricated with pumped liquid.
Advantages of Basic pumps design:
2. Ceramic radial bearings.
3. Carbon thrust bearing.
4. A protective rotor can, external rotor cover, and bearing plate are made of stainless steel.
5. Brass pump housing.
6. Thermal switch integrated in the stator coil, for motors from 300 W.
Working Conditions
1. System pressure: max. 10 bar.
2. Liquid temperature: from +2 to +110 °С.
3. Users can select a model from the type spectra according to the requirment of head, flow and frequency.
4. Power supply: voltage 230V, frequency 50Hz, single-phase AC power. The models listed in the table can also be manufactured according to user's requirement as 230V/60Hz or 115V/60Hz. Curve and performance parameters in this table represent only products with power supply of 230V/50Hz.
5. Maximum system pressure: 1.0MPa.
6. Ambient temperature:
Basic series have two kinds of pipe connections：threaded and flange. Models with power above 300W mainly have flange connection. We can make customized design according to your needs.
Pump with bronze housing is largely used in the floor heating system and delivery water for room heating. For delivering domestic hot water we recommend using pump with Copper housing(B).
Allowable temperature limits
1. The pump involves three rotational frequencies that allow selecting the best performance for a certain hydraulic system.
2. Ambient temperature :from 0 to 40 °С
3. Liquid temperature :from +2 to +110 °С
4. Storage temperature :from -30 to +55 °С
Sound pressure
Sound pressure depends on the power consumed:
≤ 50 dB(A) for models with P1<1,000 W
≤ 54 dB(A) for models with P1>1,000 W
Installation
During installation, the shaft of pump should be parallel to ground. Before start-up, open the venting screw on the top of the motor so that air in the pump can be released well, and then re-fasten the venting screw. This will help preventing pump from dry running.
