Mixed circuits in single and double pipe heating systems;

Large-scale systems in different fields such as urban apartments, suburban villas, residential water supply pressurization;

Geothermal systems ;

Hot water circulation, liquid circulation in cooling and air conditioning systems;

Boiler solar water supply,etc..

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.

 

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 1500 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 requirement of head, flow and frequency.

4. Power supply: voltage 380V, frequency 50Hz, three-phase AC power. 

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.

1. Product Certification

The product meets the certification requirements of CE, and CCC;

2. Product application conditions

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.

This performance curve is applicable to clean water at room temperature. If a circulating pump is used for non clean water media, the hydraulic performance of the pump will decrease. Therefore, when selecting a pump, the characteristics of the liquid medium being transported should be considered.
