APPLICATION

nnnn

CONSTRUCTION

nnnn

The self-priming volute casing pumps according to DIN 24255 of

nnnn

the series ULN are applied when it is necessary to suck in and to

nnnn

handle without problems and automatically, pure resp. turbid not

nnnn

aggressive liquids which do not contain any solids. So they are

nnnn

suitable for:

nnnn

drinking water supply for communities

nnnn

general water supply in agriculture, business and industry

nnnn

irrigation and drainage

nnnn

sprinkling

nnnn

pumping of condensate

nnnn

charge and discharge of fuels and oils

nnnn

Please observe: the max. geodetical suction height amounts

nnnn

to 5 m, provided that the necessary pressure

nnnn

corresponding to NPSH is not exceeded.

nnnn

Casing pressure:

nnnn

Max. 16/101) bar from -40 °C to + 120 °C

nnnn

Intermediate values can be interpolated.

nnnn

Please observe:

nnnn

Technical rules and safety regulations.

nnnn

Casing pressure = positive suction pressure + zero delivery

nnnn

head

nnnn

Position of branches:

nnnn

Suction branch directed axially, discharge branch directed

nnnn

radially upwards.

nnnn

Flanges:

nnnn

The flanges correspond to DIN 2533/2532 PN 16/101).

nnnn

Flange design drilled accord, to ANSI 150 is possible.

DESIGN

nnnn

Horizontal, self-priming single stage volume casing pumps with

nnnn

dimensions and nominal outputs accord, to DIN 24255/EN 733 in

nnnn

back pull out construction.

nnnn

The back pull out construction allows the demounting of the

nnnn

complete bearing unit towards the drive side so that it is not

nnnn

necessary to detach the pump casing out of the pipings. On ap-

nnnn

plying a coupling with dismounting piece it will be superfluous to

nnnn

detach the motor.

nnnn

The programme consists of 27 sizes with 4 suction sizes and

nnnn

needs only 2 shaft units on applying the mechanical assembly

nnnn

technique.

nnnn

Within a shaft unit, shaft sealing, impeller fastening and bearing

nnnn

cover are exchangeable.

nnnn

The side channel suction stage is arranged at the drive side of the

nnnn

volute casing. It is connected in parallel to the liquid pumping

nnnn

stage and works according to the sucking through principle.

nnnn

1) up from construction size 100-200 10 bar

nnnn

n = 1450 rpm; Designation of this construction type: A-

nnnn

n = 2900 rpm; Designation of this construction type: B-

nnnn

Bearing:

nnnn

Two greased antifriction bearings. First grease filling will be

nnnn

made in the factory.. Designation of this construction type: B

nnnn

As special design oil lubrification is possible.

nnnn

Sense of rotation:

nnnn

Clockwise when seen on the pump from the drive.

nnnn

Shaft sealing:

nnnn

The shaft sealing is made by a standard mechanical seal.

nnnn

Designation AAE: uncooled, not balanced single standard

nnnn

mechanical seal, flushed from internal

nnnn

source, O-rings Perbunan.

nnnn

Temperature range: -40 °C up to +120 °C

nnnn

Designation AA1 : as per AAE, but O-rings Viton.

nnnn

Temperature range: -40 °C up to +140 °C
