Thank you for having selected a Tsurumi submersible pump. For full benefit of this equipment, you should read, before use, the following points
which are necessary for safety and reliability anyway. The table of contents guides you to the respective warnings and instructions.
Applications
These instructions apply to the submersible pumps specified on the cover. They
are intended for use with periodic maintenance, under conditions approved by a
competent installation technician, in water of up to 40°C, with solids or
nonflammable liquids compatible with cast iron, nitrile rubber and the other
materials, without the mixture exceeding a viscosity of 10 cp (m pa•s) . During
use, discharge conduit and cabling should be touched only if need be, and the
water absolutely not. The area should be accessible to competent maintenance
technicians only, to the absolute exclusion of children and the general public. The
pumps conform to the relevant directives of the EU.
CAUTION!
The pump must not be permanently installed in swimming
pools or fountains if the installation area can be flooded.
DANGER!
The pump must not be used in an explosive or flammable
environment or for pumping flammable liquids.
CAUTION!
The pump must not be run if it has been partially dismantled
Product Description
See table for technical data; see definitions of the icons used, below. Individual
performance graphs, dimension diagrams and any other data wanted for proper
selection and installation will be gladly provided upon request by the local Tsurumi
agent.

The pumps should not be used in an atmosphere that could become explosive
nor in water that might contain traces of flammable liquid.
Handling and Storage
The pump can be transported and stored either vertically or horizontally. Make sure that it is securely lashed and cannot roll.
CAUTION!
The pump must always rest on a firm surface so that it will not
overturn. This applies to all handling, transport, testing and
installation.
CAUTION!
Always lift the pump by the lifting handle - never by the motor
cable or hose.
The time between delivery and the first hour of pumping is
extremely hazardous. Care need be taken not to crush, kink or pull the
fragile cable and not to break the hard but brittle cast iron or endanger a
bystander. No water should enter the open end of the cable during handling.
Store in a dry place to avoid corrosion by damp air inside the pump. The pump
should first be rinsed if a corrosive mixture has been pumped. Rinsing with water
mixed with cutting oil can be of some help if no dry storage is available.
Safety measures
In order to reduce the risk of accidents during service and installation work, take
extreme care and bear in mind the risk of electrical accidents.
Only a competent electrician should be allowed to work on the electrical circuit,
since only he knows the dangers involved and the regulations.
Do not connect the power supply if any part of the pump or its installation has not
been completed and inspected, or if anyone is touching the water.
CAUTION!
The lifting tackle must always be designed to suit the pump
weight. See under the heading “Product description”.
Installation:
If the pressure at the pump outlet is very low, say less than 1 bar, 1kg/cm² or 10
m H
2
O (water column), layflat hose is used nearly exclusively. Folds in the hose
can reduce or stop the flow from the pump. Using spiral reinforced hose at least
for the first 5m or so and to go over a possible wall or edge, is an improvement,
even for higher pressures. Better to use layflat hose only in straight lengths.
If the pressure at the pump outlet is high and/or hose diameter large, loosening
or rupture of a hose can result in violent movement or flooding. With large hoses
(8” to 12”), the weight of water, stiffening when (even under slight) pressure and
axial force of the water combine to make for unreliability unless expert attention
is given to selection and erection. Rigid lightweight quick-couple piping and
bends, available on the market up to 12 “, lessen the risk.
