INTRODUCTION
Sundyne Centrifugal Pumps
Sundyne API pumps provide high-energy
performance and competitive efficiencies in a
compact unit that is easy to maintain. Sundyne
pumps are single stage and are closely coupled
(OH4). Designed to increase the pressure of a
continuous flow of fluid by applying centrifugal
action, Sundyne pumps are most commonly
used in HPI, CPI, and Boiler Feed applications.
Commonly applied in refineries, petrochemical
plants, and power generation plants, Sundyne
pumps are used in high-head, low-to-medium
flow processes.
This manual presents installation, servicing,
troubleshooting, maintenance, and spare parts
information for the latest Sundyne LMV 801S
centrifugal pump. It is important that the manual
is read thoroughly before installing and
operating the pump. Images provided in this
manual are based on typical configurations.
Refer to the drawings provided with the order for
the actual configuration. Questions regarding
parts, service or operation should be directed to
your Authorized Service Center or a listed
Sundyne location.
Note: Parenthetical numbers included in the
text correspond to item numbers on the
illustrated figures. The item number
serves as a location identifier and not a
part number. The correct spare part
can be ordered referencing the item
and serial numbers. From there the
correct part number can be obtained.
Whilst every care is taken to ensure that the
information is correct, no liability can be
accepted by Sundyne or HMD Sealless Pumps
for loss, damage or injury caused by errors in or
omission from the information given.
