Your Technical Advantages
Innovative casing
-- In--line design-- Short distance between bearings and
correspondingly short shaft-- Leak--free thanks to compact casing
split flange with long prestressed bolts-- Change of the direction of rotation
possible with identical parts-- All pump sizes with double volute-- Easy mounting of self--aligning upper
casing
-- Minimum axial thrust due todouble--entry impeller
-- Optional impeller wear rings-- New vane passage with excel--
lent hydraulic characteristics
-- Completely sealed and dry for zerocorrosion
-- Short and rigid with negligible vibra--tions
-- Replaceable shaft protecting sleeves-- No threads exposed to pumped
medium, i.e. long service life and nocorrosion
-- Assembly without requiring adjustment-- Fast and easy assembly/distmantling
of the rotor components due to elasti--cally prestressed mountings
-- Computer--optimised double--entry impellers-- Smooth surfaces inside the casing and on the impeller-- Large inlet cross--sectional areas for optimum suction
behaviour-- Consistently high efficiency due to replaceable profiled
casing wear rings and impeller wear rings-- Quiet, low--wear running thanks to swirl--free intake elbow
with low energy loss
-- Grease--lubricated rolling elementbearings (allowing relubrification) fora long service life >100 000 h in alloperating ranges
-- Optional: oil lubrication-- Closed bearing brackets for low--noise
and low vibration operation
-- Asbestos--free gland packings meetingdrinking water quality standards
RDLO:Pump with bare shaft end, priming coat, gland packing, 4 instruction manuals
RDLO V:Pump with bare shaft end, baseplate, priming coat, gland packing, 4 instruction manuals
Available against extra charge:-- oil--lubricated rolling element bearings, mechanical seal, interior coating meeting drinking water quality standards,
finish coat, baseplate for pump or pump/motor, motor stools for vertical installation, materials testing, additionalinstruction manuals
Available accessories:-- coupling and coupling guard, vibration sensor SPM nipple-- set of pressure gauges, cyclone separator with piping-- vent valve, drain valve-- temperature sensor for rolling element bearing (PT 100), limit--value alarm for PT 100-- universal--joint shaft for two--floor installation
Packaging and Dispatch / Transport
RDLO:Where appropriate, the pump sets are assembled completely at the factory in order to check them for proper adjust-ment. Afterwards they are disassembled for shipping, and the components are dispatched separately.
RDLO V:The vertical pump, the motor stool, and the associated motor are dispatched separately.
Guarantee, Inspections/Testing, Quality Assurance
Each pump is subjected to a functional test. The operating data are guaranteed by way of a performance test in accor-dance with ISO 2548 C, DIN 1944/III or comparable international codes/standards.
A performance test witnessed by the customer in accordance with ISO / DIN or comparable codes/standards can beperformed against extra charge.
The quality of our RDLO products is ensured by a quality assurance system audited and certified to DIN ISO 9001/ EN 29001.

Pressure Limits
Operating Pressure and Test Pressure:
The standard test pressure is calculated as follows:1.2 x (HQ=0 + HInlet) or 1.5 x (HQ=Qopt + HInlet) The higher value is to be usedThe values for operating pressure and test pressure of the RDLO stated in the table below must not be exceeded.
Permissible operating pressures in bar Maximum permissible test pressures in bar
FlangesWhen specifying the casing flanges, the following must be observed:-- Nominal pressures of flanges � operating pressures-- Flanges of suction and discharge nozzles have equal nominal pressures-- The permissible codes/standards for the flanges and the nominal pressures are stated in the dimension tables.
