!
Equipment that will operate in a potentially explosive environment must be installed in accordance with the
following instructions.
GENERAL
Procedures for installation described within this section are
general in nature. It is assumed that the installer has a basic
knowledge of acceptable methods. More detailed
procedures are described in various publications, including API Recommended Practice 686/ PIP (Process
Industry Practices) REIE 686, “Recommended Practices
for Machinery Installation and Installation Design.”
SITE/FOUNDATION
A pump should be located near the supply of liquid and
have adequate space for operation, maintenance, and
inspection. Be sure to allow for crane or hoist service.
Model 3910 in-line pumps are designed to be mounted
directly in the piping. The pump casing has a flat base
which may be mounted on a concrete foundation which has
been poured on a solid footing.
The foundation must be able to absorb any vibration and to
form a permanent, rigid support for the pumping unit
(Fig. 6). Goulds recommends this mounting method.
Optional casing supports, which provide additional
stability, are also available (Fig. 7).
If it is intended that the piping support the pumping unit,
piping supports should be properly designed to
accommodate the weight of the pumping unit.
!
All equipment being installed must be properly
grounded to prevent unexpected static electric
discharge.
