KSB Compacta technical information

Fields of Application

Compacta lifting units are used for the disposal of sewage water below the backwash level from toilets, washrooms, showers and bathrooms in private, trade, industrial and public buildings, for example:basement flats bars, basement party rooms and saunas cinemas and theatres department stores and hospitals hotels, restaurants and pubs or schools public buildings joint sewage disposal systems for rows of houses industrial installations

Compacta can also be supplied with explosion-proof motors.

All single and duplex sets in standard design are shock-proof, standard class RK 0.63/6.3 according to safety factor A 1). They aretherefore suitable for use in public or private shelters multi-functional buildings which in case of an emergency may be used as mass shelters, e.g. basement car parks, subway systems etc., and shelters in military installations In installations in which sewage disposal must not be interrupted,

e.g. in basement flats, restaurants and pubs, cinemas etc., a standby pump (duplex pump set UZ) is required according to DIN 1986,

A Compacta U/UZ unit can be selected on the basis of the above selection charts for sewage quantities from the usual sanitary installations of a building.

If constant sewage quantities have to be drained over prolonged periods of time see page 9.

Shaft Seals

Impeller side: mechanical seal

Motor side: mechanical seal (shaft seal ring for Compacta U/UZ 30.1 and U/UZ 40.1)

The shaft seal is cooled and lubricated by a liquid chamber fitted inbetween.

operating mode S1, see type series booklet 2317.53-10

Flooding

Compacta lifting units are flood-proof.

Submersion depth: 2 m l.c.

Submersion period: 7 days

The units must not be installed in outdoor shafts.

All electrical equipment such as socket, CEE plug and

alarm transmitter must be installed in a dry location and

protected against flooding.

Electric Installation

All switchgears and control units required for operation of the unit as well as the alarm equipment are included in the scope of supply. They have to be installed in a vented room and protected against flooding. The alarm contact of the units is voltfree and can be connected to a control station.

Assembly and Installation

DIN 1986 .Drainage Systems for Buildings and Estates. stipulates that waste water produced below the backwash level and rain water from surfaces below the backwash level must be led into the public sewer system by an automatic lifting unit preventing backwash.

However, if there is a natural gradient or in rooms of secondary use faeces-containing sewage may only be drained via backflow preventers according to DIN 19 578, Part 1 when the number of users of the unit is small (e.g. single-family houses, also with integrated flats) and if there is a toilet above the backwash level. If the responsible authorities have not determined the backwash level, the backwash level is taken to be at least the street level at the connection point.

To prevent backwash from the sewer a check valve and a waste water gate valve must be installed on the discharge side (see accessories).

For exceptions see DIN 1986, Part 1, section 7.3 (for discharge lines < DN 80 or if the discharge line volume is smaller than the switching volume of the tank).

The suction line has to be equipped with a waste water gate valve as well (see accessories).

To provide further safety, the discharge line of the lifting unit must be led above the backwash level (in the form of a pipe loop).

In installations where sewage disposal must not be interrupted, a duplex pump set must be installed.

The switching volume of the unit should be at least equal to the sewage quantity above the backflow preventer.

When installing the unit in a pit leave enough space for inspection and maintenance (see installation plans).

Lead the venting pipe out of the roof. If changes of direction are unavoidable, the pipe should be laid with a gradient of at least 1:50.

Pipe connections must be provided with sound-proof insulation and have to be flexible.

If there is a risk of flooding, a collecting pit (pump sump) with a special drainage pump (e.g. Ama-Drainer) has to be provided.

Application Limits

The units are suitable for S3 operation (intermittent operation).

They ensure disposal of sewage from toilets, bathrooms, wash and shower rooms.

In case of installations where a very high sewage quantity has to be drained, for example:

- drainage of swimming pools,

- drainage of surface water in case of heavy rainfall from garage gateways and yards,

- in restaurants at peak times,

- in industrial businesses in case of shift change-over the faeces lifting unit must be selected in such way that the

QZ : QP values stated in the following table is not exceeded.







Rooms for lifting units must be dimensioned so as to ensure that there is a working area of at least 60 cm width and height next to and above all parts to be operated and serviced.
