PAGE A -- 1 SAFETY
SAFETY - SECTION A
This information applies to D Series
electric motor driven diaphragm
pumps. Refer to the manual accompa-
nying the motor before attempting to
begin operation.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and pre-
cautions for each specific application.
Therefore, it is the owner/installer’s re-
sponsibility to ensure that applications
not addressed in this manual are per-
formed only after establishing that nei-
ther operator safety nor pump integrity
are compromised by the installation.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Lock out incoming power to the
motor to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Close the discharge valve (if
used).
5. Drain the pump.
This pump is designed to handle non-
volatile non-flammable liquids contain-
ing specified entrained solids. Do not
attempt to pump volatile, corrosive, or
flammable liquids which may damage
the pump or endanger personnel as a
result of pump failure.
After the pump has been installed, block
the wheels and secure the pump to pre-
vent creeping. Make certain that the
pump and all piping or hose connec-
tions are tight, properly supported and
secure before operation.
Do not operate the pump without the ec-
centric and coupling guards in place
over the rotating parts. Exposed rotat-
ing parts can catch clothing, fingers, or
tools, causing severe injury to person-
nel.
The gearbox provided on this pump is
designed for operation at 1750 RPM
maximum input speed. If operated at a
higher RPM, pump components may be
destroyed.
Install and operate only an explosion
proof motor in an explosive atmo-
sphere. Install, connect, and operate
the motor in accordance with the Na-
tional Electric Code and all local codes.
If there is a conflict between the instruc-
tions in the manual accompanying the
unit and the National Electric Code or
the applicable local code, the National
or local code shall take precedence.
