Volute Casing Pumps self-priming ULN 32-125 . . . 125-250 PUMP TECHNOLOGY ULN P III/1 133.85210.52.01 E 02/92 TECHNICAL DATA Output: max. 300 m³/h Head: max. 95 m Suction head: max. 5 m (cold water) Speed: max. 3000 rpm Temperature: max. 120 °C Casing pressure: PN 16/101) Shaft sealing: standard mechanical seal Flange connections: DIN 2501 PN 16101) Sense of rotation: clockwise when seen on the pump from the drive APPLICATION 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 suitable for: drinking water supply for communities general water supply in agriculture, business and industry irrigation and drainage sprinkling pumping of condensate 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. DESIGN 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 applying a coupling with dismounting piece it will be superfluous to detach the motor. The programme consists of 27 sizes with 4 suction sizes and needs only 2 shaft units on applying the mechanical assembly technique. Within a shaft unit, shaft sealing, impeller fastening and bearing cover are exchangeable. 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 CONSTRUCTION Casing pressure: Max. 16/101) bar from -40 °C to + 120 °C Intermediate values can be interpolated. Please observe: Technical rules and safety regulations. Casing pressure = positive suction pressure + zero delivery head Position of branches: Suction branch directed axially, discharge branch directed radially upwards. Flanges: The flanges correspond to DIN 2533/2532 PN 16/101) . Flange design drilled accord. to ANSI 150 is possible. Speed: n = 1450 rpm; Designation of this construction type: A. n = 2900 rpm; Designation of this construction type: B. Bearing: 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. Sense of rotation: 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. Temperature range: -40 °C up to +120 °C Designation AA1: as per AAE, but O-rings Viton. Temperature range: -40 °C up to +140 °C
