In addition to the present general safety information the action-related safety
information given in the other sections must be observed.
2.1 General
▪This operating manual contains general installation, operating and maintenance
instructions that must be observed to ensure safe operation of the system and
prevent personal injury and damage to property.
▪Comply with all the safety instructions given in the individual sections of this
operating manual.
▪The operating manual must be read and understood by the responsible specialist
personnel/operators prior to installation and commissioning.
▪The contents of this operating manual must be available to the specialist
personnel at the site at all times.
▪Information and markings attached directly to the product must always be
complied with and kept in a perfectly legible condition at all times. This applies
to, for example:
– Arrow indicating the direction of rotation
– Markings for connections
– Name plate
▪The operator is responsible for ensuring compliance with all local regulations
which are not taken into account.
2.2 Intended use
▪The pump set must only be operated within the operating limits described in the
other applicable documents.
▪Only operate pump sets which are in perfect technical condition.
▪Do not operate partially assembled pump sets.
▪Only use the pump set to handle the fluids described in the data sheet or product
literature of the pump variant.
▪Never operate the pump set without the fluid to be handled.
▪Observe the limits for continuous duty specified in the data sheet or product
literature (Qmin and Qmax) (to prevent damage such as shaft fracture, bearing
failure, mechanical seal damage, etc).
▪When untreated waste water is handled, the duty points in continuous operation
lie within 0.7 to 1.2×Qoptto minimize the risk of clogging/hardening.
▪Avoid duty points for continuous operation at very low speeds and small flow
rates (<0.7xQopt).
▪Observe the minimum flow rates and maximum flow rates indicated in the data
sheet or product literature (to prevent overheating, mechanical seal damage,
cavitation damage, bearing damage, etc).
▪Do not throttle the flow rate on the suction side of the pump set (to prevent
cavitation damage).
▪Consult the manufacturer about any use or mode of operation not described in
the data sheet or product literature.
▪Only use the respective impeller types in combination with the fluids described
below.

Design The pump is designed with an axial fluid inlet and a radial outlet. The hydraulic
system sits on the extended motor shaft. The shaft runs in common bearings.
Function The fluid enters the pump axially via a suction nozzle (6) and is accelerated outward
in a cylindrical flow by the rotating impeller (7). In the flow passage of the pump
casing the kinetic energy of the fluid is converted into pressure energy. The fluid is
pumped to the discharge nozzle (4), where it leaves the pump. At the rear side of the
impeller, the shaft (1) enters the hydraulic system via the discharge cover (3). The
shaft passage through the cover is sealed to atmosphere with a shaft seal (8). The
shaft runs in rolling element bearings (9 and 10), which are supported by a bearing
bracket (2) joined to the pump casing and/or discharge cover.
Sealing The pump is sealed by two bi-directional mechanical seals in tandem arrangement.
A lubricant chamber in-between the seals ensures cooling and lubrication of the
mechanical seals.
