PAGE I - 1INTRODUCTION

INTRODUCTION

Thank You for purchasing a Gorman‐Rupp pump.

Read this manual carefully to learn how to safely

install and operate your pump. Failure to do so

could result in personal injury or damage to the

pump.

These pumps are SE Series submersible models.

The basic material of construction is stainless

steel, with stainless steel impeller. They are de

signed to handle most non‐volatile, non‐flammable

liquids, industrial chemical and low pH resistance

materials which are mildly corrosive and abrasive

that do not contain large entrained solids. Do not

attempt to pump volatile or flammable liquids that

may damage the pump.

The pumps are powered by integral, thermally‐pro

tected electric motors which are not explosion‐

proof. The pumps may be operated fully or partially

submerged. Do not operate the pumps in hazard

ous atmospheres.

All repairs to the pump motors must be performed

by a Gorman‐Rupp authorized submersible repair

facility or the factory. Any repairs to the motor as

semblies performed by the customer or an unau

thorized repair facility negates the warranty.

Because pump installations are seldom identical,

this manual cannot possibly provide detailed in

structions and precautions for every aspect of

each specific application. Therefore, it is the re

sponsibility of the owner/installer of the pump to

ensure that applications not addressed in this

manual are performed only after establishing that

neither operator safety nor pump integrity are com

promised by the installation. Pumps and related

equipment must be installed and operated ac

cording to all national, local and industry stan

dards.

If there are any questions regarding the pump or

its application which are not covered in this man

ual or in other literature accompanying this unit,

please contact your Gorman‐Rupp distributor, or

The Gorman‐Rupp Company:

The following are used to alert maintenance per

sonnel to procedures which require special atten

tion, to those which could damage equipment, and

to those which could be dangerous to personnel:

Immediate hazards which WILL result in

severe personal injury or death. These

instructions describe the procedure re

quired and the injury which will result

from failure to follow the procedure.

Hazards or unsafe practices which

COULD result in severe personal injury

or death. These instructions describe

the procedure required and the injury

which could result from failure to follow

the procedure.

Hazards or unsafe practices which COULD

result in minor personal injury or product

or property damage. These instructions

describe the requirements and the possi

ble damage which could result from failure

to follow the procedure.

NOTE

Instructions to aid in installation, operation, and

maintenance or which clarify a procedure.

PAGE A - 1SAFETY

SAFETY ‐ SECTION A

This information applies to SE Series

submersible electric motor driven

pumps.

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.

Do not operate this pump where explo

sive vapors or flammable material exist.

Death or serious injury will result.

Before attempting to open or service the

pump:

1. Familiarize yourself with this man

ual.

2. Unplug the pump power cable to

ensure that the pump will remain

inoperative.

3. Allow the pump to completely cool

if overheated.

This pump is designed to handle most

non‐volatile, non‐flammable liquids, in

dustrial chemical and low pH resistance

materials which are mildly corrosive

and abrasive and do not contain large

entrained solids. It is not designed to

pump volatile or flammable materials.

Do not attempt to pump any liquids

which may damage the pump or endan

ger personnel as a result of pump fail

ure.

Never attempt to alter the length or re

pair any power cable with a splice. The

pump motor and cable must be com

pletely waterproof. Damage to the pump

or personal injury may result from alter

ations.

After the pump has been installed, make

certain that the pump and all piping or

hose connections are secure before op

eration.

Do not attempt to lift the pump by the

power cable, piping or the carry handle.

Attach proper lifting equipment to the

lifting handle fitted to the pump.

Obtain the services of a qualified elec

trician to troubleshoot, test and/or ser

vice the electrical components of this

pump.

Pumps and related equipment must be in

stalled and operated according to all na

tional, local and industry standards.

INSTALLATION - SECTION B

Review all SAFETY information in Section A.

Do not operate this pump where explo

sive vapors or flammable material exist.

Death or serious injury will result.

This section only summarizes recommended in

stallation practices for the pump. If there are ques

tions concerning your specific application, contact

your local distributor or the Gorman‐Rupp Com

pany.

Pumps and related equipment must be in

stalled and operated according to all na

tional, local and industry standards.

PREINSTALLATION INSPECTION

Before installation, inspect the pump for damage

which may have occurred during shipment. Check

as follows:

a. Inspect the pump assembly for cracks, dents,

damaged threads, and other obvious dam

age.

b. Check for and tighten loose attaching hard

ware.

c. The pump is furnished with a 30‐foot (9 meter)

long power cable. Inspect the cable for cuts or

damage.

d. Carefully read all tags, decals, and markings

on the pump assembly, and perform all duties

as indicated.

If anything appears to be abnormal, contact your

Gorman‐Rupp distributor or the factory to deter

mine the repair or updating policy. Do not put the

pump into service until appropriate action has

been taken.

Lubrication

The shaft seal and bearings in this pump are fully

lubricated from the factory. No additional lubrica

tion is required.

PUMP INSTALLATION

Pump Dimensions

The pumps are provided with suction strainers to

prevent large solids from clogging the impeller.

See Figure 1 for the approximate physical dimen

sions of the pumps.

Lifting

Pump unit weights will vary depending on the

mounting and drive provided. Check the shipping

tag on the unit packaging for the actual weight, and

use lifting equipment with appropriate capacity.

Drain the pump and remove all customer‐installed

equipment such as suction and discharge hoses

or piping before attempting to lift existing, installed

units.

Attach a rope or chain to the lifting handle on the

top of the pump. Do not lift the unit by the power

cable or the discharge piping. Customer installed

equipment such as rigid discharge piping must be

removed before attempting to lift.

Figure 2. Do Not Lift Pump by Power Cable

Do not attempt to lift the pump by the

power cable or piping. Attach proper

lifting equipment to the handle on the

pump.

OM-06497SE SERIES

PAGE B - 3INSTALLATION

Positioning the Pump

This pump is designed to operate fully or partially

submerged; however, it should not be operated

dry for extended periods of time.

Extended dry operation will destroy the

seal assembly.

Never place the pump on loose or soft ground; the

pump could sink, preventing water from reaching

the impeller (see Figure 3).

Figure 3. Do Not Place Pump

on Loose Ground

Secure and support the pump by the handle on

the pump. If the bottom is heavily sludge‐covered,

rest the pump on support blocks or suspend it near

the surface of the liquid. If the application involves a

lot of debris, protect the pump from excessive wear

and clogging by suspending it in a perforated bar

rel or culvert pipe. See Figure 4 for correct pump

installations.

The pump is provided with a suction strainer to pre

vent large solids from clogging the impeller. Any

spherical solids which pass through the strainer

will pass through the pump.

PAGE B - 4 INSTALLATION

PIPING

The pump volute is equipped with a standard

2-inch NPT tapped discharge connection. Either

hose or rigid pipe may be used for the discharge

connection.

For maximum pumping capacity, use non‐collaps

ible hose or rigid piping, and keep the discharge as

short and straight as possible. If rigid piping is

used, minimize the use of elbows and fittings which

increase friction losses and reduce pump perform

ance.

A check valve or throttling valve may be installed in

the discharge line to control siphoning or back flow

when the pump is shut off.
