WARNING
!
CAUTION
Ø
Use only genuine DELLMECO parts when replacing component parts of this product.

In case of pumping a hazardous fluid (hot, flammable, strong acid, etc.) with this pump, protective measures
(install a pit, a protection box, sensors, etc.) must be provided in consideration of possible leakage of fluid.
Warning signs must be displayed at necessary places. Leakage of fluid may cause fire or accident.

In case a diaphragm gets damaged, fluid penetrates the internal side of diaphragm chamber and, together with air,
is being pushed out to the opposite chamber through an air hose. That may cause incorrect operation and finally
damage of the pump. When using the hose, make sure to use a model with appropriate corrosion resistance for the
fluid to be pumped.
Ø
DO NOT exceed the pump’s rated pressure, speed or temperature, or change the system/duty parameters
from those for which the pump was originally supplied, without confirming its suitability for the new duty.
Otherwise, the following results may follow: damage to the pump, or even a severe, possibly fatal accident.

Some fluid may remain inside the pump and inside the connected piping after shutting down the pump, or if
the pump is left unused for a prolonged period.
Therefore, be sure to purge the system of fluid and clean the pump before prolonged disuse.
The fluid remaining in the connected piping, as well as in the pump itself, may expand because of freezing or
heat, which may cause damage to the pump or/and piping, and lead to leakage of the fluid.

Before using this pump, get fully familiar with the precautions regarding the fluid to be pumped, and verify the
corrosion resistance of the parts that will come into contact with the fluid. NEVER use the pump with any fluid
against which it does not have sufficient corrosion resistance, or with a fluid that poses a risk of explosion. If you
are unable to verify the corrosion resistance, please contact with DELLMECO Office. Using this product
with any fluid against, which the parts in contact with the fluid do not have sufficient corrosion resistance,
may result in damaging the product or leakage of fluid.

A device must be incorporated into the pump, system, or drive, to prevent the pump exceeding its stated
duty pressure
. Do not allow the pump to operate with a closed/blocked discharge unless a pressure relief
device is incorporated. If an integral relief valve is incorporated into the pump, do not allow re-circulation
through the relief valve for extended periods.
Ø
DO NOT attempt to dismantle a pressure relief valve which has not had the spring pressure relieved, or it is
mounted on a pump that is operating. Serious personal injury or death and/or pump damage may occur.

DME Pump is not originally equipped into a pushbutton switch with differential pressure control.
Pushbutton switch must be assembled to the pump or installation obligatorily by a customer. DELLMECO
DME Series Pump can be equipped by supplier with such safety device, but only on customer’s request.
