aximum temperature of the water through the pump
is 165oF (85oC).
In order to obtain maximum performance in terms of
duration of seals and valves, it is necessary to respect
a few simple rules, as follows:
1) In order to avoid damage caused by cavitation,
the pump must be pressure fed.
The higher the inlet pressure, the longer the life of
the wet end of the pump.
When working at 185oF (85oC), the minimum
feed pressure - measured directly in the inlet port
of the pump when it is working - is 45 psi (3 bar).
The minimum feed pressure accoridng to the
different temperatures are:
Naturally, if the application allows for feeding the pump
with 45 psi (3 bar) even at low temperatures
(for example: 115oF/45oC the life of the wet end of the
pump will be even longer.
2) The plumbing which feeds the pump must be
of a diameter at least equal to the inlet port.
Also, follow the suggestions below:
a) ake the plumbing as short and straight as
possible, preferably in an upward direction to
facilitate the expulsion of eventual air bubbles
naturally if compatible with the requirements
of the system.
b) It is always useful to put a filter at the inlet
with capacity of 4 to 5 times the flow of
GENERAL PUMP A member of the Interpump Group EP Series
Instructions and Recommendations for the Installation of
EP Series Pumps
the pump, for example for a 4 gpm (15 l/min)
pump, put a filter from 16 to 20 gpm (60-
75 l/mi)The mesh size suitable for this
application is 0.016” (.4 mm).
c) It is extremely important to put a pressure
switch on the suction port of the pump, and in
any case downstream from the filter, so that
it can stop the pump should the feed pressure
drop by 20% due to the filter clogging or
failure of the feed pump, etc.
3) Change of oil
We recommend the first oil change after the
first 50 hours, with the pump stopped and
the oil still warm.
This change is not recommended because the oil
has lost its properties, but rather to eliminate the
impurities that have gotten into the oil during the
running-in phase. If these impurities are not
removed, but are allowed to remain in the oil, they
may cause premature wear to the moving parts
and the oil seals. After this initial change, the
oil can then be changed every three months
or 300 hours of operation thereafter.
Please note: If the pump works in conditions with
high humidity and with sharp temperature
changes, it is possible that condensation will
appear inside the crankcase, which mixing with
the oil can change its properties. This is easy
to see because the oil changes to a white, milky
color.
If the pump does not have excessive water
leaking from the packings, and the oil becomes
milky, the oil has to be changed more frequently.
The percentage of water in the oil must not
exceed 20%.
Use oil per the following chart:
