7 General data AP, KP Construction 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 23 V +6/ 1%, 3 x 23 V +6/ 1% or 3 x 4 V +6/ 1%, 5 z. 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; Ex-pumps, however, require manual restart. Three-phase Ex-pumps have a thermal switch in the motor windings. The thermal switch is to be connected to the control circuit of a motor starter. Ex-pumps require manual restart. 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. AP8 Vortex and AP1 pumps are suitable for vertical or horizontal dry pit installation. Pumps in permanent submersible installations can be installed by means of a stationary auto-coupling at the 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 autocoupling and connected to the pipe system. Due to this system, the pump can easily be pulled up for service. Pumps for vertical dry pit installation can be installed by means of a stationary dry pit stand with suction bend. For free-standing installation the AP7 and AP1 pumps must be fitted with a base stand, see accessories. Sectional drawing AP (Ex) TM

8 Technical data Drainage pumps KP KP The KP pump is designed for liquid transfer and drainage of clean or slightly dirty waste water with the pump completely or partly submerged in the liquid. drainage of cellars or buildings, pumping of domestic waste water without toilet waste, groundwater lowering, emptying applications, eg. in pools, tanks and vessels and pumping applications within agriculture, dairy industry, horticulture and process industry. Approvals Z according to Institut für Bautechnik, Berlin Pumped liquids Pumps without level switch or with float switch: The pump is suitable for the pumping of clean, non-aggressive water and slightly dirty (grey) waste water. If the pump has been used for other liquids than clean water, it should be flushed through with clean water immediately after use. The open impeller construction ensures a free passage of solids up to a diameter of ø1 mm. Pumps with vertical level switch: The pump must only be used for the pumping of clean ground water and drain water. Operating range Installation depth: Min. liquid temperature: Max. liquid temperature at continuous operation: Max. 1 metres below liquid level. C. 5 C. During continuous pumping the suction strainer must always be completely covered by the liquid. Max. liquid temperature: 7 C for periods not exceeding 2 minutes at intervals of at least 3 minutes. TM Discharge KP 15, KP 25 and KP 35: Rp 1¼ Pump sleeve and housing Single-stage, submersible, stainless steel, drainage pump in a robust design with upwards-pointing discharge port placed on top of the pump. The water enters the pump through the holes of the suction strainer preventing the passage of large solids. The sturdy impeller has single curved vanes with bevelled front edges that prevent fibres from jamming the impeller. The guide vanes in the pump housing not only guide the liquid but also lift sand grains into the liquid flow and thus prevent blocking by sand. The outer casing is made in one piece. The mains cable and the cable of the level switch are combined in one vulcanized and watertight plug, which is secured to the socket of the hermetically sealed stator housing. Motor The motor is a single- or three-phase, asynchronous canned motor with liquid-filled rotor chamber and water lubricated bearings. The motor is cooled by the pumped liquid around the motor. Enclosure class: IP 68. Insulation class: F. The motor incorporates automatic overload protection which cuts out the motor in case of overload. When it has cooled to normal temperature, the motor will restart automatically. Materials Components Materials DIN W.-Nr.

The pump is suitable for the following applications ground water lowering, pumping in drainage pits, pumping in surface water pits with inflow from roof gutters, shafts, tunnels, etc., emptying of ponds, tanks, etc., pumping of fibre-containing wastewater from laundries and industries, pumping of domestic wastewater from septic tanks and sludge treating systems and pumping of domestic wastewater with/without discharge from water closets. Approvals PA-I no. 414 and VDE. Automatic operation The pump is available for automatic as well as manual operation and can be installed in a permanent installation or used as a portable pump. The pump is available: with level switch fitted for automatic ON/OFF operation between two liquid levels (single-phase pumps); with separate level switch and control box for automatic ON/OFF operation between two liquid levels (three-phase pumps); without level switch for manual ON/OFF operation Pumps fitted with level switches can also be used for manual ON/OFF operation. In this case the level switch must be secured in an upwards-pointing position. Pump sleeve and housing The stainless steel pump sleeve is made in one piece and equipped with an insulated carrying handle. The suction strainer is clipped on to the pump housing and can easily be removed for maintenance. The strainer not only prevents the passage of large solids but also ensures a slow flow into the pump. TM Shaft and bearings The shaft is made of stainless steel and rotates in maintenance-free prelubricated ball bearings. Impeller The stainless steel impeller is a Vortex impeller with L-shaped blades and a clearance of 5 mm (in the pump housing). The blades are curved backwards to reduce any harmful effect from solid particles and to reduce the power consumption. The impeller has a protective cap to prevent the deposits of long-fibred material. Shaft seal The shaft seal is a combination of a mechanical shaft seal of the bellows type and a lip seal with 6 ml oil between them. The shaft seal has silicon carbide seal faces.

All types are designed for voltage tolerances of ±1%. 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 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 through a 1 metres long cable. The mains cable between the pump and the control box is 1 metres long. The mains cable of the control box is an.8 metres long free cable end. The control box includes a motor starter, and for singlephase 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 pump type, see "Product range", page 81. Pumps with control box without float switch for manual on/off operation The mains cable between the pump and the control- box is 1 metres long. The mains cable of the control box is an.8 metres long free cable end. The control box includes a motor starter and an operating capacitor but no relays for float switch. 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 capacitor. Level controller A level controller and switches are available as optional extras for the control, monitoring and protection of three-phase 5 z AP pumps. Level controller LC is designed for one-pump operation, and LCD for twopump operation.
