Design
Mono-stage, horizontal centrifugal pump, self-priming when fluid is in the
housing.The pump is equipped with a semi-open wheel. It is maintenance
free with mechanical seals. It is secured against dry running. Both, pump and
motor are mounted on a portable painted steel frame. The versions TUP are
with handles and hand guard.
Pressure proof vaccum gauge DIN 14 421 - G 566 is installed on the pressure
side. Pumps TUP 3-1,5 C and TUP 3-1,5 CL are in accordance with DIN 14 424.
Protective motor switch, plug and light socket are explosion-proofed of the
protective ignition systems II 2G EEX de II C T6. On types CL and BL are
fitted with explosion-proofedlight socket 230 V for connecting a hand lamp.
Materials
Housing, Cover, delivery bend Aluminium DIN EN 1706
Impeller Brass DIN EN 1982
Diffuse special cast iron DIN EN 1561
Mechanical seals Carbon / Silicon carbid (SiC)
Gaskets oil resistant elastomers NBR (Perbunan)

Motor
Three-phase motor duty type S1 (continuous operation) according DIN
VDE 0530. Explosion-proof motor II 2G, explosion group IIB, T3.
The motor is protected by an explosion-proof plug with thermal and electromagnetic
circuit breakers adjusted for the nominal current. The thermal release characteristic
corresponds with VDE 0165. An approval was given for the explosion category
II2G EX ed II C T6.
Application Area
The portable transfer pump (TUP) is designed for mobile use at fire brigades and
other aid organizations for pumping of flammable liquids and wastewater. hey can
also be used in the industrial sector, however, must not be in permanent installation.
Before each start-up, the liquidlevel in the pump housing must be check and fill up if
necessary. Brief interruptions are permitted, if it is ensured that the liquidlevel in the
pump housing does not decrease by evaporation or emptying by suction process.
This can be ensured by a non-return or a shut-off valve (see section safety
instructions)These additionalparts are not scope of serial delivery. The required
"direction of rotation test (see section startup) may only be carried out outside the
danger area before application.A brief dry run (<30 s) is permitted.
Permitted pumped media:
Liquids with solids acc. to technical data (p.10) and viscosity <1.5 cm²/s consisting of
wastewater with solids < 4 mm, flammable liquids of explosion group IIAor IIB, T-
class T 3 to T 1, acids or bases according to the material resistance. The GUP is
and can thereby be operated on a high safety level. Devices in this category are
intended for use in areas in which it is to be expected that an explosive atmosphere
occurs consistingof gas, mist and vapors. The explosion protection measures
ensure the required level of security even in the event of frequent device
malfunctions or faults that can usually be expected.
