1. For water pressure boosting in household like apartment, villa, residences, cooling or air-conditioning system internal circulation, and boiler and solar system ,etc.

2. One- or two-pipe heating systems

3. Underfloor heating systems

4. Mixing loops of large heating systems

BASIC S pumps are of the canned-rotor type, i.e. the pump and motor form a single unit without shaft seal that uses only two sealing gaskets. Bearings are lubricated with pumped liquid .

These pumps feature:

Ceramic radial bearings;

Carbon thrust bearing;

Stainless steel protective rotor can and bearing plate;

Impeller made of corrosion-resistant material;

Cast iron pump housing with cataphoretic coating.

Pumps are supplied with a three-speed motor.

Two- or four-pole asynchronous squirrel-cage motor.

A terminal box can be easily opened and is equipped with clips for cable connection.

A cable inlet has a sealing and device to reduce mechanic stress in the cable.

The cable inlet can be protruded outside from the guide bush for easier installation.

Easy access to the terminal box with a cable tension compensator.

The motor complies with the Low Voltage Directive (LVD).

There are different configurations with different positions of terminal boxes to provide correct cable connection.

Insulation class: H.

Basic S three phase circulation pump provided with 3-speed control function, which allow the operator to shift speed and meet the requirements of different using conditions. It is featured by high cost-eff iciency ratio,low noise,long service life, safe and leakage-free, easy for maintenance.

Working Conditions

It is designed to delivery clean and rarefied fluid, non-corrosive, non-explosive and does not contain and solid particles,fibers,or mineral oil. It is strictly forbidden to transfer flammable liquid, like diesel and gasoline.

Ambient Conditions:0℃— 40℃, Dry and free from dust

Liquid temperature:2℃—110℃

Max. Pressure(Bar):0.6/1.0MPa

Rated Voltage:1*220V/ 3*380V

Frequency :50HZ

Installation

Pump must be installed with shaft in a horizontal position. When starting the pump, loosen the deflating screw on the top of the motor to release the internal air. It is strictiy required not to avoid dry running the pump.
