Safety Rules
The operating instructions must be read and
adhered to before performing any work on
the pump or complete assembled unit. No
responsibility will be carried by us for damage
to materials or per-sons caused by improper
handling of our pumps.
Access to the pump is not allowed for unauthorized
personnel. A safety valve is to be installed in
accordance with the guidelines for liquid spraying units
so that the admissible operating pressure cannot be
ex-ceeded by more than 10%. Pump operation without
a safety valve as well as any excess in temperature or
speed limits automatically voids the warranty.
When the pump is in operation, the driven shaft side
and its coupling must be covered by a protective
guard. The plunger area must also be covered by the
protective plate (30).
Do not step onto the protective plate (30) nor put
weight on it.
Pressure in the discharge line and pump must be at
zero before carry-ing out any maintenance work to the
pump or unit. Close off suction line. Disconnect fuses
to ensure that the driving motor cannot get switched
on accidently. Make sure that the pump, the cooling
system and all parts on the pressure side of the unit
are vented and refilled, with pressure at zero, before
starting the pump.
In order to prevent air or an air/water-mixture
being absorbed and cavi-tation occurring, the
pump-npshr, positive suction head and water
tem-perature must be respected.
Cavitation and/or compression of gases
lead to uncontrollable pressure-kicks which
can ruin the pump and unit parts and also
be dangerous to the operator or anyone
standing nearby.
Giant plunger pumps are suitable for pumping
clean water and other non-aggressive or non-
abrasive media with a specific weight similar to
water.
Before pumping other liquids - especially
inflammable, explosive and toxic media -
the pump manufacturer must be consulted
with regard to the resistance of the pump
material. It is the responsibil-ity of the
equipment manufacturer and/or operator to
ensure that all pertinent safety regulations
are adhered to.
