General safety information
The operating instruction has to be considered as:
• part of the product.
• must be read by the operator before starting and must
be followed during operation.
• must be handed over to any following owners or users
of the product.
• must be completed by the user for any additional

Principles of safety
The apparatus is constructed in conformity with the state of
the art and approved safety-related standards. Danger however
can occur during use if:
• it is operated by unskilled personnel
• it is used improperly
• maintenance or service is incorrectly.
Following safety information must be observed:
1. The pump may only be operated in an upright position.
2. Ensure that the pump is resistant to the medium being
pumped.
3. Note the limit values for temperature, viscosity and density
of the medium being pumped.
4. The motor must rotate in the direction indicated by the
arrow (B70V).
5. Ensure that all connections and fittings are properly
tightened.
6. Ensure that the motor is switched off before connecting to
the electricity supply.
7. The drive motor must be located outside the mobile
container or drum.
8. Note the maximum immersion depth.
9. The pump may only be operated with the discharge closed
if a bypass valve with return line has been installed.
10. The pump must not be allowed to run dry. Pump must be
switched off when the container is empty.
11. Wear appropriate protective clothing when handling
hazardous liquids. Face mask or goggles, apron and
gloves.
12. Do not reach into the intake port of the pump.
13. The leakage port must be checked for leaks.
14. The pump may only be repaired by the manufacturer or a
duly authorized repair shop.
Application in explosion hazard areas or pumping flammable
liquids the following points must be noted additionally:
1. Only use pump tubes with identification according to ATEX
directive.
2. Only use PTFE stators and stator sleeves marked with
PTB-No. for flammable liquids.
3. Only use following explosion proof drive motors:
B70V-HD-D: Three-phase motors and compressed air
motors with a power of up to 1 kW and a max. speed of
900 1/min.
B70V-HD-SR: Universal motors with a power of up to 1 kW
and a max. speed of 14400 1/min.
4. Provide a motor protection and an on/off switch against
automatically starting the pump when inserting the plug.
5. Electric connection in explosion hazard areas only with
explosion proof plug or explosion proof terminal box.
6. Connect the equipotential bonding between pump tube and
container before starting operation.
7. Use conductive pressure hoses and conductive hose
connections.
8. Do not pump low conductive liquids. Electrostatic danger
may occur.
9. Do not use the drum pump for stationary operation.
10. The pump must not be left unattended while in
operation.
11. The pump may only be repaired by the manufacturer
or a duly authorized repair shop. Only use genuine Lutz
replacement parts. The setting values of the mechanical
seal must be observed without fail. Otherwise inadmissible
warming up will occur.
The national accident prevention regulations must be observed
without fail.
