F = External force, tensile or compression
M = External moment, clockwise or counter-
clockwise
•
Forces and moments may be applied
simultaneously in any direction
•
Values apply to all materials
•
Higher loads may be acceptable, if direction
and magnitude of individual loads are known,
but these need approval
•
Pumps must be on rigid foundations and
baseplate fully grouted
•
Pump/Baseplate should not be used as pipe
anchor. Expansion joints must be properly tied
•
If in doubt, contact Flowserve for information
3.3.4 Pump lubricant data
Pump bearings and mechanical seals are oil
lubricated. The oil levels in their respective
chambers are monitored via fitted sight glasses.
The recommended oil is Mobil DTE Medium or
Castrol Hyspin AWH46.

3.3.6 Temperature limitations
3.3.6.1 Working temperature
The allowable pump working temperature range is
0 °C to +75 °C (32 °F to +167 °F).
3.3.6.2 Ambient temperature
These pumps are generally fitted with TEFC motors
with an ambient temperature limit of 0 °C to +40 °C
(32 °F to 104 °F). Specific pumps may be fitted wit h
motors to suit the client’s requirements with other
ambient temperature limits – see motor nameplate
for details.
4 INSTALLATION
4.1 Location
When selecting the location, be sure to install the
unit as close as practicable to the source of the
liquid to be pumped. Allow adequate space for
access, ventilation and maintenance operations
involving dismantling and inspection of parts.
Headroom is an important consideration as an
overhead lift of some type is required for installation
and maintenance of the pump-set.
4.2 Foundation
4.2.1 Install pump units
There are many methods of installing pump units to
their foundations. The correct method depends on
the size of the pump unit, its location, and noise
vibration limitations. Non-compliance with the
provision of correct foundation and installation may
lead to failure of the pump and, as such, would be
outside the terms of the warranty.
4.2.2 Mount baseplate
The baseplate should be mounted onto a firm
foundation, either an appropriate thickness of
concrete or sturdy steel framework. It should NOT
be distorted or pulled down onto the surface of the
foundation, but should be supported to maintain the
original alignment. The location of the foundation
bolts and size of bolt holes can be obtained off the
General Arrangement Drawing (See section 8.7).
