INTRODUCTION

Patterson pumps, when properly installed and operated, and when given reasonable
care and maintenance, will operate satisfactorily for a long period of time. This manual
outlines the general principles that should be considered to ensure trouble-free pump
operation.

Patterson pumps are built in a wide variety of designs and for many different services.
This instruction manual should be studied carefully and followed, as there may be
specific requirements for this unit and application that cannot be covered in a general
discussion. These special instructions included within should be read thoroughly before
operating the equipment.

These instructions must always be kept close to the product's operating
location or directly with the product.

These instructions are intended to facilitate familiarization with the product and its
permitted use. Operating the product in compliance with these instructions is important to
help ensure reliability in service and avoid risks. The instructions may not reflect all
current legal requirements and local regulations; ensure that such requirements and
regulations are observed by all, including those installing the product. Always coordinate
repair activity with operations personnel, and follow all plant safety requirements and
applicable safety and health laws/regulations.

GENERAL GUIDELINES

SAFETY PRECAUTIONS

WARNING

Do not operate this equipment in excess of its rated speed or other than in
accordance with the instructions contained in this manual.

The equipment has been found satisfactory for the conditions for which it was sold, but
its operation in excess of these conditions may subject it to stresses and strains which it
was not designed to withstand.

For equipment covered by this instruction book, it is important to observe safety
precautions to protect personnel from possible injury. Among the many considerations,
personnel should be instructed to:



avoid contact with rotating parts



avoid bypassing or rendering inoperative any safeguards or protective devices



avoid extended exposure in close proximity to machinery with high noise levels



use proper care and procedures in handling, lifting, installing, operating and
maintaining the equipment



do not modify this equipment – consult factory if modification is deemed
necessary



do not substitute for repair parts which can be provided by the equipment
manufacturer. Safe maintenance practices with qualified personnel are
imperative.

Failure to heed this warning may result in an accident causing
personal injury.

Upon delivery of the pumping unit verify that all items on the bill of lading are present.
Also verify that the pump unit is not damaged. Immediately report any shortages or any
damage to the Freight Company. List the damage or shortages on the bill of lading and
the freight bill.

SECTION 1

GENERAL INFORMATION

This manual covers the installation, operation and maintenance of Patterson Pump
HVES-CC pumps. The pump is a centrifugal, single stage; single suction type furnished
with mechanical seals. When properly installed and when given reasonable care and
maintenance, centrifugal pumps should operate satisfactorily for a long period of time.
Centrifugal pumps use the centrifugal force principal of accelerating the liquid within a
rotating impeller, and then collecting it and converting it to pressure head in a stationary
volute.

The pump consists of two assemblies:

1.

Volute assembly or stationary part

2.

Rotating element or moving part

The back pullout design allows for removal of the motor and integral rotating element
without disturbing the suction and discharge piping. The suction and discharge nozzles
are drilled and tapped for gauge connections. Pump casings are drilled and tapped for
complete pump drain. Casing wear rings are provided as standard equipment.

SECTION 2

STORAGE & PROTECTION

All pumps are shop serviced and ready for operation when delivered, but there are
occasions when considerable time elapses between the delivery date and the time the
pump is put into operation. Equipment which is not in service should be kept in a clean,
dry area. If equipment is to be stored for long periods of time (six months or more); the
following precautions should be taken to insure that the equipment remains in good
condition.

1.

2.

3.

Be sure that the motor bearings are lubricated.
Unpainted-machined surfaces, which are subject to corrosion, should be

protected by some corrosive resistant coating.
The shaft should be rotated 10 to 15 revolutions by hand periodically in order to

spread the lubricant over all the bearing surfaces. Suitable intervals are from one
to three months, depending on atmospheric conditions, etc. In order to insure
that the pump shaft does not begin to sag, do not leave the shaft in the same
position each time.
