to the bypass duct principle, with self-priming

function following the initial priming.

Pump and motor form a complete unit. The impeller

is fixed on the driving shaft extension. The shaft

sealing is effected with a rotary shaft seal in stand-

ard versions and a rotary mechanical seal in special

versions -UO12. The sealing for the case is effect-

ed with a gasket and O-ring.

The pump is to be protected against coarse parti-

cles.

The KC pumps are mounted next to or on top of the

tank. The pumps are foot mounted and must be

screwed down in order to ensure a secure stance.

2.2 Intended use

nance, inspection and assembly must be adequate-

ly qualified. Scope of responsibility and supervision

of the personnel must be exactly defined by the

plant operator. If the staff does not have the neces-

sary knowledge, they must be trained and instruct-

ed, which may be performed by the machine manu-

facturer or supplier on behalf of the plant operator.

Moreover, the plant operator is to make sure that

the contents of the operating manual are fully

understood by the personnel.

3.5 Safety instructions relevant for opera-

tion

•If hot or cold machine components involve

hazards, they must be guarded against acci-

dental contact.

•Guards for moving parts (e.g. coupling) must not

be removed from the machine while in opera-

tion.

•Any leakage of hazardous (e.g. explosive, toxic,

hot) fluids (e.g. from the shaft seal) must be

drained away so as to prevent any risk to per-

sons or the environment. Statutory regulations

are to be complied with.

•Hazards resulting from electricity are to be

prevented (see for example, the VDE Specifica-

tions and the bye-laws of the local power supply

utilities).

•The pumps are only secured safely if properly

attached to the floor or top of the tank.

3.6 Safety instructions relevant for mainte-

nance, inspection and assembly work

Any work on the machine shall only be performed

when it is at a standstill, it being imperative that the

procedure for shutting down the machine described

in this manual be followed.
