Installation
Installation
This section is a general installation and operating instruction for most Goulds pumps. Specific
text and illustrations are included in this section. To insure pump performance and operating
life, proper installation and reasonable maintenance are required. The following instructions are
a guide for installation and maintenance personnel and the pump operator.
Preparation for shipment
Goulds pumps are prepared at the factory for shipment under covered conditions. They are
protected for transport and short term covered storage. Unless otherwise specified, it is
assumed the pump will be installed upon delivery. Additional protection can be provided by
request.
Installation
accordance with the following instructions.
electric discharge. If not, a static electric discharge may occur when the pump is drained and
disassembled for maintenance purposes.
Location of unit
The pump should be located in a clean, dry area free from flooding. The area should provide
adequate space for maintenance and repair, considering complete disassembly and handling
of equipment. The unit should be positioned to provide the most efficient pipeline system.
Piping
WARNING:
pump. This may impose dangerous strains on the unit and cause misalignment between pump
and driver. Pipe strain will adversely effect the operation of the pump resulting in physical injury
and damage to the equipment
CAUTION:
WARNING:
received with order. Reference Hydraulic Institute for NPSH and pipe friction values needed to
evaluate suction piping.
Short, direct suction and discharge pipelines and a minimum of elbows and fittings result in the
least amount of pipe friction.
Suction piping
1. Excessive friction losses will cause cavitation.
2. Must be kept free of air leaks, particularly in long lines or conditions of high suction lift.
3. Flow regulating valves must not be located on suction side of the pump.
Discharge piping
1. Excessive friction losses result in insufficient head.
4
Equipment that will operate in a potentially explosive environment must be installed in
All equipment being installed must be properly grounded to prevent unexpected static
Never draw piping into place by forcing at the flanged connections of the
Pump must never be throttled on suction side.
NPSHa must always exceed NPSHr as shown on Goulds performance curves
