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.
