INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

I. INTRODUCTION

Warning levels applying to the safe installation, operation and maintenance of all

sizes of WSP™ Self-Primer (WSP) pumps can be located at the beginning of this

manual. You must refer to the manual accompanying your power source before

attempting to begin operation since Weir Specialty Pumps has no control over or

special knowledge of the power source to which you will connect these pumps.

You have made a wise decision in your purchase of a WSP™ Self-Primer (WSP)

pump, and we thank you for your business. To learn how to install and operate your

pump safely, read this manual carefully. Failure to follow the enclosed instructions

may result in damage to the pump or personal injury. The WSP™ Self-Primer Pump

Installation, Operation, and Maintenance manual was created to help you maximize

the pump’s performance while achieving the longest life possible.

Your pump is a centrifugal, self-priming model featuring a semi-open impeller and

suction check valve. The pump is designed with external shimless adjusters for

setting the wear plate to impeller clearance. It pumps liquids containing large,

entrained solids as well as slurries. Its basic material is ductile iron with a cast steel

impeller and a steel wearplate.

For questions about the pump or its application not covered in this manual or other

documentation included with the unit, please contact your WSP™ distributor, or write

to:

Weir Specialty Pumps

P.O. Box 209

Phone: (801) 359-8731

Contact the power source manufacturer’s local dealer or representative for

information or technical assistance on your power source before attempting

installation or operation of this Weir Self-Primer Pump.

PURPOSE

This manual is designed for all levels of users from a novice to an experienced

operator. It provides employees with known procedures requiring extra attention as

well as providing information on unsafe situations that could damage the equipment

and/or be dangerous to the operator. While Weir Specialty Pumps is providing you

with this information, we cannot anticipate or provide detailed precautions for every

situation that could occur during maintenance of the unit.

It is your responsibility, as the owner and/or maintenance person, to be sure you

Rev. 3 01/09/20

WHEN A MANUAL SHUT-OFF VALVE IS INSTALLED IN A BYPASS LINE, IT MUST

REMAIN OPEN DURING OPERATION. CLOSING THE MANUAL SHUT-

OFF VALVE

COULD CAUSE A PUMP, WHICH

HAS LOST PRIME, TO CONTINUE TO OPERATE

WITHOUT REACHING PRIME. THIS COULD CAUSE DANGEROUS OVERHEATING OF

THE PUMP AND POSSIBLY RUPTURE THE PUMP CASING.

BEFORE SERVICING, ALLOW SUFFICIENT TIME FOR THE OVERHEATED PUMP TO

COMPLETELY COOL. ONCE THE PUMP HAS

COMPLETELY COOLED, DRAIN THE

LIQUID FROM THE PUMP BY REMOVING THE CASING DRAIN PLUG. WHEN

REMOVING THE DRAIN PLUG, USE CAUTION. FAILURE TO DO SO MAY RESULT IN

INJURY. PLATES, COVERS, GAUGES, OR FITTINGS MUST NOT BE REMOVED FROM

AN OVERHEATED PUMP. LIQ

UIDS IN THE PUMP CAN REACH BOILING

TEMPERATURES AND PRESSURE INSIDE THE PUMP CAN CAUSE PARTS TO BE

EXPELLED VIOLENTLY.

BEFORE SERVICING, ALLOW SUFFICIENT TIME FOR AN OVERHEATED PUMP TO

COMPLETELY COOL. ONCE THE PUMP HAS COMPLETELY COOLED, DRAIN THE

LIQUID FROM THE PUMP BY REMOVING THE CASING DRAIN PLUG. WHEN

REMOVING THE DRAIN PLUG, USE CAUTION. FAILURE TO DO SO MAY RESULT IN

INJURY. PLATES, COVERS, GAUGES, OR FITTINGS MUST NOT BE REMOVED

FROM AN OVERHEATED PUMP. LIQUIDS IN THE PUMP CAN REACH BOILING

TEMPERATURES AND VAPOR PRESSURE INSIDE THE PUMP CAN CAUSE PARTS

TO BE EXPELLED VIOLENTLY.

WHEN PERFORMING EQUIPMENT MAINTENANCE OR IF THE PUMP IS TO

REMAIN OUT OF SERVICE FOR A PERIOD OF TIME, THE EQUIPMENT

ELECTRICAL SERVICE MUST BE DISCONNECTED WITH AN APPROVED

LOCKOUT AND KEY. FAILURE TO LOCK OUT THE EQUIPMENT MAY RESULT IN

INJURY.

1. IF OVERHEATED, THE PUMP MUST BE ALLOWED TO COMPLETELY

COOL BEFORE ATTEMPTING ANY PROCEDURES.

2. CHECK THE TEMPERATURE BEFORE OPENING ANY COVERS,

PLATES, OR PLUGS.

3. ENSURE THAT SUCTION AND DISCHARGE VALVES ARE CLOSED.

4. SLOWLY AND CAREFULLY VENT THE PUMP.

5. DRAIN THE PUMP.

ONCE THE PUMP HAS BEEN POSITIONED, ENSURE THAT ALL PUMP AND PIPING

CONNECTIONS ARE TIGHTENED, SECURED, AND SUPPORTED PROPERLY.

ALL GUARDS AND PROTECTIVE DEVICES MUST BE INSTALLED BEFORE THE PUMP

IS STARTED. CONTACT WITH UNGUARDED BELTS, SHEAVES, OR COUPLINGS

COULD RESULT IN INJURY.

PLATES, COVERS, GAUGES, PIPE PLUGS, OR FITTINGS MUST NOT BE

REMOVED FROM AN OVERHEATED PUMP. VAPOR PRESSURE WITHIN THE

PUMP MAY CAUSE PARTS TO BECOME DISENGAGED AND EJECTED WITH

GREAT FORCE, CAUSING POTENTIAL SEVERE INJURY TO PERSONNEL.

ALWAYS ALLOW THE PUMP TO COOL BEFORE SERVICING ANY EQUIPMENT.

DO NOT OPERATE PUMP WITH BOTH SUCTION AND DISCHARGE VALVES CLOSED

OR WITH SUCTION OR DISCHARGE BLOCKED BY CLOGGING – THIS COULD CAUSE

DAMAGE AND IS DANGEROUS. THESE PUMPS ARE TO BE USED FOR LIQUID

SERVICE ONLY. EXCESSIVE PRESSURE CAN CAUSE MALFUNCTION LEADING TO

INJURY.

PUMP LIFTING EYES ON THE SELF-PRIMING PUMP ARE ONLY DESIGNED TO

HANDLE THE WEIGHT OF THE BARE PUMP. BEFORE LIFTING, ENSURE THAT

ALL SUCTION AND DISCHARGE HOSES AND PIPING HAVE BEEN REMOVED

FROM THE PUMP, AND THE PUMP IS FREE FROM ANY BASE OR DRIVER.

ENSURE THAT THE BYPASS LINE IS DIRECTED BACK INTO THE WET-

WELL OR TANK

TO PREVENT HAZARDOUS SPILLS AS SOME LEAKING (1 TO 5 GALLONS [3.8 TO 19

LITERS] PER MINUTE) WILL OCCUR WHEN THE VALVE IS IN THE FULL-

CLOSED

POSITION.

WHEN CHECKING ALIGNMENT YOU MUST FIRST DISCONNECT THE POWER

SOURCE.

YOUR PUMP HAS BEEN ENGINEERED TO PUMP LIQUIDS THAT CONTAIN SOLIDS OR

SLURRIES. AT NO TIME SHOULD THE LIQUID BE VOLATILE

, CORROSIVE, OR

COMBUSTIBLE. FAILURE TO DO SO C

OULD DAMAGE THE PUMP OR RESULT IN

INJURY.

AFTER THE PUMP CASING HAS BEEN FILLED, REINSTALL AND TIGHTEN THE FILL

PLUG. FAILURE TO OPERATE THE PUMP WITHOUT ALL CONNECTION PIPING

SECURELY INSTALLED COULD CAUSE LIQUID IN THE PUMP TO BE FORCED OUT

UNDER PRESSURE AND MAY RESULT IN INJURY.

PRIO

R TO WORKING ON THIS PUMP, ALWAYS LOCK OUT OR DISCONNECT THE

PUMP FROM ITS POWER SOURCE. IT MUST REMAIN INOPERABLE DURING REPAIRS.
