3 UNISELB benefits that ensure operational safety and cost-effectiveness in continuous operation. TABLE OF CONTENTS Non-clogging system Starting at DN, the non-clogging-system ensure the greatest possible operational safety. It is guaranteed by a combination of a hard, unprocessed surface of the wear plate, interchangeable from DN and higher, and a specially processed cutting edge on the impeller.

Motor shaft Rigid motor shafts made from high-alloy stainless steel for minimal deflection. Shaft seal Single or double-acting mechanical seal with state-of-the-art highly wear-proof materials. By-pass channel For optimal flushing of mechanical seal by means of the pumped medium. Cost-effectiveness An extended lifetime is achieved through liberally dimensioned shafts and bearings. 7 Operational safety The greatest possible operational safety is reached through the crushing of long-fibre ingredients on the cutting ring (DN and higher). Oil chamber Starting at DN, optimized oil chamber for lubrication and cooling of the mechanical seals.

4 Technical descriptions Use The maintenance-free self-priming dirty water pump UNISELB with high suction capacity in a short operating time is particularly suitable for pumping slightly contaminated water, heating oil, chemicals, essences, cooling water, acids, liquors, solvents, tan liquor, tannic acid, filtration water, lime solution, washing water, rinsing water, sea water and ground water. Starting at DN, even the pumping of coarse contaminated sewage water is possible. They are used for filling and emptying tanks, containers, fish ponds, swimming pools, etc., for pumping out tanks and cleaning decks of ships, for watering in gardening nurseries and in road building for draining of construction sites, mines, cable trenches, foundations and cellars. Installation The pumps are to be used in a horizontal installation. orizontal installation of the pump Impellers Open multi vane impellers ensure trouble-free operation. Starting at DN, the impellers are equipped with a non-clogging system. Open multi-vane impellers (see Versions page 9) are used for lightly contaminated and sludgy media without rope-forming fibrous substances or gas and air inclusions. Construction igh circulation rates with minimum space requirements are achieved by means of an easy-to-install and readily serviceable compact design. The self-priming function of the pump is ensured after the pump casing has been filled and by an intended use of the pump. Due to the installed non-return flap valve the discharging of the pump casing is prevented. Non-clogging system Starting at DN, all pumps are equipped with an automatic non-clogging-system. The installed wear plates, interchangeable from DN and higher, with particularly hard surfaces even abrade the entrained textiles insofar as this function is required for a fault-free flow. At Q optimal this system has sufficient power reserve of the rated motor power available.

5 Technical descriptions Range of performance Speed Q max [m /h] max 9 rpm ( z) rpm ( z) rpm ( z) 7 rpm ( z) 9 rpm ( z) rpm ( z) Bearing The pump and motor have a common shaft, which is supported by a strengthened bearing. In contrast to the standard motor, the pump-side rigid bearing is designed as a reinforced bearing for long life under extreme operating conditions. The high level of running accuracy of the motor shaft is achieved through the high flexural rigidity and short shaft length. This ensures vibration-free running of the mechanical shaft seal. Shaft seal The shaft seal on the pump side is effected in all models via a maintenance-free mechanical seal, which is independent of the direction of rotation and made from wear-resistant silicon carbide (SiC). The required cooling of the sliding surfaces is generated in a targeted manner through the medium via a bypass channel. Starting at DN, long-fibre ingredients are crushed by the rear cutting ring of the impeller. In series with a double-acting mechanical seal (standard for DN and higher) a mechanical seal made from wear-resistant silicon carbide (SiC) provides the seal on the pump side and a carbon/chromium molybdenum cast mechanical seal provides the seal on the drive side. The intermediate casing is filled with lubricating oil to lubricate and cool the mechanical seals. This oil even enables a short-term dry run. The intermediate casing can be optionally monitored for leaks using a seal electrode. For DN to DN and with the DW construction (without Florence flask), the motors used are equipped with a special seal for splash-proofing on the pump side. Noise The noise emission is determined by complex influencing factors such as size, materials, operating and installation conditions. Noise emission was contained using hydraulic measures and solid construction methods as early as in the development stage. The maximum sound pressure level is generally determined by the drive motors, being caused by air, magnetic and bearing noises. Noise levels are below the permissible limit curves specified for electrical motors as defined by DIN EN -9. Minimum noise emission during operation in the area of Q optimal (best efficiency).

IE motors already achieve the efficiencies now that will be required by law starting in. Ship's engines are an exception: they are still available in Standard Efficiency Class (IE). The motor is optionally available with an integrated or external frequency converter. The use of a frequency converter is often recommended due to energetic reasons, but not compulsory. Motor technology with energy efficiency IE/IE The new technology of remium Efficiency motor (IE) and igh Efficiency motor (IE) offers three decisive advantages: More performance due to very high effi ciency Reduced operating costs due to high energy savings Reduced CO emissions due to lower power consumption Design IM B/V Motor connection Manufacturer-specific rotection type I Speed 9 () rpm (7) rpm 9 () rpm Frequency () z Connection.
