Circulating pumps hold all the required certificates anddeclarations in accordance with the directives of European Union.Circulating pumps for the domestic appliances are tested andsafety attested by TÜV Rheinland and meet all the requirements inareas of electromagnetic compatibility.Circulating pumps with dry rotor are accommodated to demandsfrom directives of the "New Approach" and the followingstandards, and are therefore signed with the CE sign.
Factory of electric machines SEVER was founded in 1923. In theearly eighties of the previous century, the production span hasbeen extended to production of pumps. ATB SEVER is a subsidiaryof ATB Austria Antriebstechnik AG since 2005. and is recognized byit's experience and tradition in production of circulating pumpswith wet and dry rotor.Certification of quality management system has been carried outin 1997.ATB SEVER has a certificate issued by the certification bureau SZSBeograd according to JUS ISO 9001/2001.
Well esteemed certification bureaus (TÜV Rheinland, BureauVeritas, Lloyd's Register, CENE laboratory) that certify productsconduct supervision and accept certificate of quality managementsystem.

Choice of pump
Choosing the circulating pump with wet rotor considering theworking characteristics
Regular supplies of warm water for consumers in systems ofcentral heating is one of the highly relevant issues of urbancommunities.Circulating pumps are meant for forced circulation of fluids in:
systems of central heatingcooling systemssolar systemsindustrial applications.
Depending on the application, presupposed fluids in the systemare:
softened water of certain quality, according to the regulations,free from acids, bases, residues and hard particleswater mixed with glycol based liquids for anti-freezingproperties
Choosing the pump needs to consider several issues such as:pump application, rating, dimensions and connection, technicalcharacteristics and areas of application, design, fluid to betransported, used materials.The catalogue lists data needed for correct choice of a pump anddata for correct functioning of the system, without appearance ofcavitation or additional noise due to fluid flow velocity.In order to avoid the appearance and harmful effects of cavitation,it is necessary to take into consideration several parameters:
static pressure of transported fluidtemperature of transported fluidminimal pressure at the pump inlet.
Danger of cavitation increases if the transported liquid has highertemperature and lower pressure.

Circulating pump with wet rotor should be chosen such that therequired working point is on the Q-H characteristic of the pump atthe highest rotational speed or as near to it as possible. If therequired working point is between characteristics of two pumps,then the pump with lower characteristic should be chosen.
For correct choice of these pumps it is necessary to know reliablythe highest required working point of the pump. Considering theworking characteristics, pumps are being chosen so that workingpoint is in the area of high efficiency, meaning, in the area ofsecond and third third of Q-H characteristics. If the workingconditions are not well known, it is recommended to select thepump of higher power.
Depending on the application, a certain type of mechanical seal isbeing installed in the pumps with dry rotor.Standard type of mechanical seal is being installed in pumps fortransport of softened water and water mixed with liquid againstfreezing with content of glycol up to 20%.Life of mechanical seal is being decreased if the pump is beingused in difficult environment: water of inappropriate quality withhard particles, high pressure and temperature.
For correct operation of a system that incorporates a pump withwet rotor it is necessary to have some value of pressure on thepump inlet. Values of the minimal required pressure on the pumpinlet Hs[m] are shown in the table.

Cavitation reserve NPSH
Flow velocity of transported fluid
Installation of pumps with wet rotor
Cavitation reserve (NPSH) is pump characteristic and determinesminimal pressure at the pump inlet. It is the boundary value forpump operation at which cavitation does not appear yet or theappearing cavitation shall not cause any damage.Values of NPSH are characteristics quoted in the catalogue, andare obtained by measuring. When choosing the pump, the quotedvalues need to be enlarged by a safety add on of 0.5m.
Flow rates of transported fluid are shown on some graphs ofQ-H characteristics.During the process of system design, it is necessary to make surethat flow velocity of the fluid through the pipelines does not exceedthe shown value of flow velocity within the pump.
Pumps can be installed in various positions, in thrust orreturning pipeline. It is essential that the shaft is in horizontalposition.Mounting a pump into the pipeline is to be done by:
standard screwed connections (1RS)standard flanges (1CVR and 1CV).

Installation of pumps with dry rotor
Pumps can be installed in all positions, except in position wheremotor is under the pump.Pumps up to size CS 100 can be installed directly in the welldimensioned pipeline without additional support.Pumps CS 100 and larger need to be attached to the base over thefeet on the pump housing.In case of installing in the horizontal installation we recommendsupporting the pipeline.

DesignThese are centrifugal single-stage pumps. The pump and theelectric motor share a common shaft which rotates in slidebearings lubricated by the transported fluid.This design provides silent and reliable operation of the pump.Pump housing is of "in line" layout what allows it to be mountedinto a straight pipeline, since the suction and dischargeconnection are coaxial.
Selection of the pump rotational speed is being done by the switchon the pump motor terminal box. By choosing the appropriaterotational speed, hydraulic characteristics of the pump are beingadapted to the cooling or heating system the pump is installedinto. This provides significant energy savings.

Design
Pump parts
Materials of the pump parts:
The single - stage centrifugal pump is of monoblock design. Thisallows it to be mounted in-line with the pipeline, since the suctionand discharge connection are coaxial. The drive assembly: electricmotor, mechanical seal and impeller are compact anddynamically balanced. This assembly can be easily dismountedwhile the housing pump stays in the pipeline.Advantages of this layout are great working safety, longevity, lownoise level, operation without vibration with possibility ofmeasuring the pressure in the inlet and outlet end.
