TECHNICAL DATA Suction head: Casing pressure: Shaft sealing: Flange connections: standard mechanical seal clockwise when seen on the pump from the drive The self-priming volute casing pumps according to DIN 24255 of the series ULN are applied when it is necessary to suck in and to handle without problems and automatically, pure resp. turbid not aggressive liquids which do not contain any solids. So they are drinking water supply for communities general water supply in agriculture, business and industry charge and discharge of fuels and oils Please observe: the max. geodetical suction height amounts to 5 m, provided that the necessary pressure corresponding to NPSH is not exceeded. Casing pressure: Intermediate values can be interpolated. Please observe: Technical rules and safety regulations. Casing pressure = positive suction pressure + zero delivery Suction branch directed axially, discharge branch directed radially upwards. Flange design drilled accord, to ANSI 150 is possible. Horizontal, self-priming single stage volume casing pumps with dimensions and nominal outputs accord, to DIN 24255/EN 733 in back pull out construction. The back pull out construction allows the demounting of the complete bearing unit towards the drive side so that it is not necessary to detach the pump casing out of the pipings. On ap- plying a coupling with dismounting piece it will be superfluous to The programme consists of 27 sizes with 4 suction sizes and needs only 2 shaft units on applying the mechanical assembly Within a shaft unit, shaft sealing, impeller fastening and bearing The side channel suction stage is arranged at the drive side of the volute casing. It is connected in parallel to the liquid pumping stage and works according to the sucking through principle. 1) up from construction size 100-200 10 bar n = 1450 rpm; Designation of this construction type: A- n = 2900 rpm; Designation of this construction type: B- Two greased antifriction bearings. First grease filling will be made in the factory.. Designation of this construction type: B As special design oil lubrification is possible. Clockwise when seen on the pump from the drive. Shaft sealing: The shaft sealing is made by a standard mechanical seal. Designation AAE: uncooled, not balanced single standard mechanical seal, flushed from internal source, O-rings Perbunan. Designation AA1 : as per AAE, but O-rings Viton.

Material design Casing seal: For casing sealing a flat type seal of special paper is used. Designation of this construction type: 2 Drive / Speed and co-ordination of the suction stages: Drive by commercial electric motors, construction type IM B3. Drive by V-belt is admitted up to 1,5 kW drive power. On request, drive by Diesel engines or gasoline motors. The suction stages have been co-ordinated to the different construction sizes in such a manner that an optimal time at an economical drive power will be attained. On selecting of the motor size for the pump unit this constant drive power...
