SUPER T SERIES OM-07174

PAGE A - 1SAFETY

SAFETY ‐ SECTION A

This information applies to Super T Se

riesrengine driven pumps. Refer to the

manual accompanying the engine be

fore 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. Shut down the engine, remove the

key and disconnect the positive

battery cable to ensure that the

pump will remain inoperative.

3. Allow the pump to completely cool

if overheated.

4. Check the temperature before

opening any covers, plates, or

plugs.

5. Close the suction and discharge

valves.

6. Vent the pump slowly and cau

tiously.

7. Drain the pump.

This pump is equipped with an automat

ic starting system, and is subject to au

tomatic restart. Keep hands and cloth

ing away from the unit to prevent injury

during automatic operation. Disconnect

the positive battery cable before per

forming any maintenance. Failure to do

so may result in serious personal injury.

This pump is designed to handle dirty

water containing specified entrained

solids. Do not attempt to pump volatile,

corrosive, or flammable liquids which

may damage the pump or endanger per

sonnel as a result of pump failure.

Death or serious personal injury and

damage to the pump or components

can occur if proper lifting procedures

are not observed. Make certain that

hoists, chains, slings or cables are in

good working condition and of suffi

cient capacity and that they are posi

tioned so that loads will be balanced

and the pump or components will not be

damaged when lifting. Suction and dis

charge hoses and piping must be re

moved from the pump before lifting. Lift

the pump or component only as high as

necessary and keep personnel away

from suspended objects.

After the unit has been installed, make

certain that the pump and all piping or

hose connections are tight, properly

supported and secure before operation.

Do not operate the pump against a

closed discharge valve for long periods

SUPER T SERIESOM-07174

PAGE A - 2 SAFETY

of time. If operated against a closed dis

charge valve, pump components will

deteriorate, and the liquid could come

to a boil, build pressure, and cause the

pump casing to rupture or explode.

Do not remove plates, covers, gauges,

pipe plugs, or fittings from an over

heated pump. Vapor pressure within the

pump can cause parts being disen

gaged to be ejected with great force. Al

low the pump to cool before servicing.

Do not operate an internal combustion

engine in an explosive atmosphere.

When operating internal combustion

engines in an enclosed area, make cer

tain that exhaust fumes are piped to the

outside. These fumes contain carbon

monoxide, a deadly gas that is color

less, tasteless, and odorless.

Natural gas presents an extreme explo

sion and fire hazard. Follow all safety

precautions outlined by the National

Fire Protection Association when de

signing and installing the system. Make

certain that the regulators and fuel lines

are of the proper size and capacity for

the system, and that all fuel lines are se

curely connected and free of leaks.

Fuel used by internal combustion en

gines presents an extreme explosion

and fire hazard. Make certain that all

fuel lines are securely connected and

free of leaks.

Never tamper with the governor to gain

more power. The governor establishes

safe operating limits that should not be

exceeded. Refer to the performance

curve in Section E for the maximum con

tinuous operating speed for this pump.

Pumps and related equipment must be in

stalled and operated according to all na

tional, local and industry standards.

SUPER T SERIES OM-07174

PAGE B - 1INSTALLATION

INSTALLATION - SECTION B

Review all SAFETY information in Section A.

Since pump installations are seldom identical, this

section offers only general recommendations and

practices required to inspect, position, and ar

range the pump and piping.

Most of the information pertains to a standard

static lift application where the pump is positioned

above the free level of liquid to be pumped.

If installed in a flooded suction application where

the liquid is supplied to the pump under pressure,

some of the information such as mounting, line

configuration, and priming must be tailored to the

specific application. Since the pressure supplied

to the pump is critical to performance and safety,

be sure to limit the incoming pressure to 50% of the

maximum permissible operating pressure as

shown on the pump performance curve.

For further assistance, contact your Gorman‐Rupp

distributor or the Gorman‐Rupp Company.
