Basic 25-5SB1. Commercial heating pump system
2. Domestic hot water recirculation
3. Domestic heating pump system
4. Hot-water heating systems of all kinds
5. Industrial circulation systems
6. Cold water systems and air-conditioning systems
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:
1. Single or three-speed motor.
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. Cast iron 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: 0℃ ～40℃, temperature of medium: 2 ℃ ～110 ℃. In order to avoid condensed water in stator, make sure the ambient temperature is lower than liquid temperature.
7. Medium: thin, clean, non-corrosive and non-explosive liquid, does not contain any solid particles, fibers or mineral oil. Pump must not be used for delivering flammable liquids, such as diesel and gasoline.
8. Delivering liquid of high viscosity will reduce performance of the pump, so while choosing a pump, the viscosity of the medium must be taken into consideration.
9. Maintain minimum pressure at the pump inlet to avoid cavitation noise and damage to pump bearings.
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 housing is generally made of cast iron. Bronze and stainless steel pump housing is also available.
Pump with cast iron housing is widely used for delivering water for room heating. Pump with bronze housing is largely used in the floor heating system. For delivering domestic hot water we recommend using pump 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.
