General operating instructions for Berkefeld pumps
Filled with water/surface water, this portable multi-purpose pump is self-priming and
determined for lifting of contaminated water and sludge water. Due to its size and its
weight it is especially intended as transportable multi-purpose pump, but it can also be
used as stationary pump for continuous operation. It must not be flooded by the material
to be conveyed and not be used in potentially explosive areas. It has to be used so that
life and material do not become endangered in case of malfunction.
Combustion-engined pumps only to be used in the open air or in well-aerated rooms with
tight exhaust pipe into the open air (exhaust gas hose)
- danger of poisoning!
In spite of the simple the use and installation of the pump we recommend
to observe these operating instructions. This will avoid damage, and the
pump will be ready for operation at any time and will have a long service
life.
Please give these operating instructions to the pump operator. We are, of course,
prepared to send you another copy free of charge.
The pump may only be operated by trained expert personnel. We particularly point
to keeping to the relevant rules and regulations.
Commissioning
Install the pump as near to the suction point as possible.
Fill the pump casing with the liquid to be pumped through suction or pressure manifold.
Connect suction pipe and delivery pipe.
Never operate without strainer!
Operation without strainer or protective sieve inevitably leads to destruction of the pump
due to penetration of big solids.
Start the motor according to the operating instructions. Should these instructions not be
ready at hand, the following hints will help you.
The suction process is effected automatically. Depending on the suction head and length
of the suction pipe, the lifting starts after 10 to 300 seconds. The suction head is max. 7 m
WC. If possible, the suction length should not exceed 3 x 3 m.
