7.1 Submerged installation on auto­coupling

Pumps for permanent installation can be installed on
a stationary au to- co up li n g gu ide r ail system.
See fig. A, pag e 8.

The auto-coupling system facilitates maintenance
and service as the pump can easily be lifted out of
the tank.

Warning
Before beginning installation

procedures, make sure that the
atmosphere in t h e t a nk is not
potentially explosive.

Make sure th at t he p ip e wo r k is
installed without the use of undue
force. No loads from the pipework
weight must be c ar rie d b y th e p ump .
We recommend the use of loose
flanges to ea se t h e i n st allation and to
avoid pipe tension at flanges and bolts.

Do not use elas tic e le m ent s or be llo w s
in the pipework; th es e e lem en ts sh oul d

pipework .

Proceed as follows:

1. Drill mou nti ng h oles f or t he g uide ra il bra ck et on

the inside of th e tank and fasten the guid e r a i l
bracket provisionally with t wo scr e ws.

2. Place the auto-coupling base unit on the bottom

of the tank. Use a plumb line to establish the
correct positi o ni n g. Fas t en t he au to coup li n g wi th
expansion bolts. If the bottom of the tan k is
uneven, the auto-coupling base unit must be
supported so that it is level when bei ng fastened.

3. Asse mble th e disc harg e lin e in accor danc e with

the generally accepted procedures and without
exposing the line to distortion or tension.

4. Place the guide rails on th e au to -coupling base

unit and adjust the length of the rails accurately

submerged as water may penetrate
through the cable into the motor.

7.2 Free-standing submerged installation

Pumps for fr ee -s tand i n g s ub m er ge d installation can
stand freely on the bottom of the tank or the like.
See fig. B, page 9.

In order to facilitate service on the pump, fit a flexible
union or coupling to the elbow on the discharge line
for easy s epar at ion .

If a hose is used, make sure that the hose does no t
buckle and that the inside diameter of the hose
matches that of the pump discharge port.

If a rigid pipe is used, fit the union or coupling, non­return valve and isolating valve in the order
mentioned, when viewed from the pump.

If the pump is installed in m udd y c ondit ions or o n
uneven ground, we recommend to support the pump
on bricks or a similar support.

Proceed as follo ws:

1. Fit a 90 ° elbow to the pump discharge port and
connect the discharge pipe/hose.

2. Lower the pump into the liquid by means of a
chain secured to the lifting bracket of the pump.
We recommend to place the pump on a plane,
solid foundation. M ak e sur e th at th e pu m p is
hanging from the chain and not the cable.

3. Hang up the end of the chain on a suitable hook
at the top of th e tank a nd in su ch a w a y t ha t th e
chain cannot com e in to co ntact with the pump
housing.

4. Adjust the length of the motor cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation. Fasten the relief
fitting to a suitable h oo k. M ak e s ure th at th e
cables are not sharply bent or pinched.

8.4 Thermal switches

Note

English (GB)

All pumps have two sets of thermal switches
incorporated in the stator windings.

Thermal switch, ci rcuit 1 (T1 -T3), bre aks the cir cui t
at a winding temp erat ure of appro x. 150 °C .

This thermal switch must be c onn ec ted
for all pumps.

Thermal switch, circuit 2 (T1-T2), breaks the circuit
at a winding temperature o f app rox. 170 °C (three­phase pumps) or 160 °C (single- phase pum ps).

Warning
After thermal cutout, explosion-proof

pumps must be restarted manually.
The thermal s wi tc h ( cir c u it 2) m u s t b e
connected for manual restarting of
these pumps.

Maximum operating current of the thermal switches
is 0.5 A at 500 VAC and cos φ 0.6. The switches
must be able to break a coil in the supply circuit.

In the case of standard pumps, both thermal
switches can (when closing the circuit after cooling)
generate automatic restarting of the pump via the
controller.

Warning
The separate motor-protective circuit

breaker/control box must not be
installed in pot en t ia lly e xplo s iv e
environments.
