Construction Sectional drawing

Vertical, single-stage, submersible centrifugal pumps
with horizontal or vertical discharge port designed for
free-standing installation or installation by means of an
auto-coupling guide rail system or for pit installation.
The pumps are directly connected to an asynchronous
submersible motor for
• 1 x 230 V ±10%, 60 Hz
• 3 x 230 V ±10%, 60 Hz
• 3 x 380 V ±10%, 60 Hz or
• 3 x 460 V ±10%, 60 Hz.
Enclosure class: IP 68.
Insulation class: F (155°C).

Stainless steel pumps

Single-phase pumps incorporate thermal overload
protection and require no additional motor protection.
Three-phase pumps must be connected to a motor
starter.

Cast iron pumps

APG pumps have a built-in thermal protection which
cuts off the motor in case of overload. The motor restarts
automatically.
Some three-phase pumps have a thermal switch in the
motor windings.

Installation
The pumps are suitable for free-standing installation as
well as installation on an auto-coupling guide rail
system, which is available as an accessory.
Pumps in permanent submersible installations can be
installed by means of a stationary auto-coupling at the

TM01 4260 5098

bottom of the pit. Two guide rails going to the top of the
pit ensure that the pump is positioned correctly when
lowered from the top of the pit down to the auto-
coupling and connected to the pipe system. Due to this AP80.100.21
system, the pump can easily be pulled up for service.
For free-standing installation the AP80 and APG pumps
must be fitted with a base stand, see accessories.

AP30 Impeller
The impeller is a vortex impeller in cast iron GG 25 with
a free passage of 30 mm in the pump housing. Cast iron
is chosen as it is resistant towards mechanically
wearing particles.

AP50 The stainless steel pump housing is fitted with an

internal riser pipe ensuring high efficiency. The riser pipe
has a number of holes which enable efficient cooling of
the motor during operation. The cable entry is of the
socket and plug connection type, which makes quick and
easy dismantling possible.

Discharge port
All AP50 pumps have a threaded vertical discharge port:

 Technical data AP51 Vortex

AP51 with Vortex impeller Impeller

The impeller is a vortex impeller in cast iron GG 25 with
a free passage of 51 mm in the pump housing. Cast iron
is chosen as it is resistant towards mechanically wearing
particles.

TM01 2617 2098

TM01 7174 4099

The pumps are used for pumping wastewater, sludge-

containing water, considerable quantities of surface Shaft seal
water and ground water in places such as AP51.65.14, Combination of mechanical bellows
• holiday homes, AP51.65.15: seal and lip seal. The primary shaft
seal is made of silicon carbide/silicon

AP51.65.35, The primary and the secondary shaft
If permitted by local laws or regulations, the AP51 Vortex AP51.65.36: seals are made of silicon carbide/
pumps can be used for the pumping of sewage from silicon carbide. The chamber between
single and multi-family houses. the primary and the secondary shaft
seals is oil-filled. Between the lower
Pump and stator housing ball bearing and the stator housing
there is a lip seal.
The pump housing and the stator housing are made of
cast iron.

Control box
Variants
The AP pump range comprises versions with or without
control box and float switch, versions designed for
single-phase or three-phase power supply versions.
All types are designed for voltage tolerances of ±10%.

Pumps with control box and float switch

Some AP pumps can be supplied with a float switch for
automatic start/stop of the pump. The float switch cable
should be fastened to the retainer on the pump handle.
The difference in level between start and stop may be

TM00 6671 2298

adjusted by adjusting the free length of cable between
the float switch and the retainer.
Large difference in level: Long cable.
Small difference in level: Short cable.
The float switch is connected directly to the control box Pump with control box and float switch.
through a 10 metres long cable.
The mains cable between the pump and the control box
is 10 metres long. The mains cable of the control box is
an 0.8 metres long free cable end.
The control box includes a motor starter, and for single-
phase pumps also an operating capacitor. The pumps
require no further motor protection.
An alarm signal can be given in case of a too high level
by means of a separate float switch connected to an
alarm. The high-level alarm switch and the alarm are
available as accessories.
Further information about control boxes for a specific

Pumps without control box.

Pumps without control box must be connected to a
separate motor starter. The motor starter is available as
an accessory.
Single-phase pumps must also be connected to a capac-
itor.

Level controller
A level controller and switches are available as optional

extras for the control, monitoring and protection of

three-phase 60 Hz AP pumps. Level controller LC is
designed for one-pump operation, and LCD for two-

Level switches Dimensions

The AP pumps in combination with LC 108 or LCD 108 are
available with level switches for automatic level control.
Level switches supplied by Grundfos are of the non- B
mercury type.
LC 108 can be fitted with up to three level switches:
1. Min.: Stops the pump.
2. Max.: Starts the pump.
3. Alarm: Alarm (optional):
high water level or pump fault.
LCD 108 can be fitted with up to four level switches:

H
1. Min.: Stops both pumps.
2. Max. 1: Starts one pump.
3. Max. 2: Starts the other pump.
4. Alarm: Alarm (optional):
high water level or pump fault.
The level switches are to be installed in the pit floating
on the pumped liquid.
The position of the level switches decides when LC 108 or
LCD 108 starts and stops the AP pumps:

TM01 9007 0303

• When the level switch is pointing upwards, the level L
switch contact will be closed and the pump will start.
• When the level switch is pointing downwards, the
the level switch contact will be opened and the pump
will stop.
