III. Product Description
Description
This section provides a general description of the Goulds Model GSP and key
engineering specifications.
Overview
The Goulds model GSP pumps are single stage, end suction, centrifugal pumps designed
to meet the rigorous standards of hygiene needed by the food and beverage industries.
Pumps are used in the food industry as process or clean in place pumps.
The GSP series meets 3A Sanitary Standards for Centrifugal and Positive Rotary Pumps,
Number 02-10 and 3A Sanitary Standard for Machine Leveling Feet and Supports,
Number 88-00 for both internal and external hygienic design. This enables operators
to insure the purity of their process and the cleanliness of their plant to meet both local
and national health and safety regulations. Not all products marked 3A meet these
design and clean-ability standards.
Mechanical seals are FDA approved and several versions of the pump have EHEDG
European sanitary certification.
Pump impellers are fully open, and either threaded or key driven and held in position
by an impeller bolt and o-ring. Impeller hubs are extended through the seal and
backplate eliminating the need for shaft sleeves.
Casings are full volute in design. 316 Stainless parts and welds are polished to
Ra<0.8 um.
Suction and discharge connections are Tri-clamp sanitary flange type.
Close-coupled units have NEMA standard JM motors with C-face mounting and key
driven shaft extension or for smaller pumps, NEMA standard 56J motors with threaded
shafts. Pumps are available with standard ODP or TEFC motors with shrouds and
pump stands or wash down enclosures. These are provided for hygienic cleaning of the
pump and its surroundings.

Engineering Data
Noise level
The noise generated by a pump depends on different factors. Most important are: power,
speed and brand name of the motor, whether there is cavitation or not, operating point
of the pump, and handling of small quantities of air. A guide value for the sound pressure
level measured in dB(A) at a distance of 3 feet from the pump with a 2 pole motor
operating at 60 Hz in ideal circumstances with cold water is 78 dB(A) for pumps up to 5
hp, 83 to 85 dB(A) for pumps with motors ranging from 7.5 to 50 hp. For pumps with 4
or 6 pole motors, the value can be decreased with +/- 8 dB(A).
Maximum Liquid Temperature:
250ºF (120ºC)
Note: Pump and piping should be protected from skin contact if temperature is less
than 10ºC or higher than 40ºC
Maximum Working Pressure (Fluid temperature dependant):
S1 – 125 PSIG (9 Bar); S2 – 150 PSIG (10.5 Bar)
Maximum Suction Pressure:
=125 PSIG/150 PSIG – Pump generated pressure (see performance curve)
Starts per hour:
20 evenly distributed with standard across the line start
Unlimited with soft starter or drive

IV Installation
Description
This section covers the general information and cautions about installing your pump as
well as specific steps to take during installation.
Location
Locate the pump as near to the liquid source as practical and below the level of the
liquid for automatic self priming. If the pump must be above the liquid source, a foot
valve must be provided on the suction pipe.
Allow adequate space around the pump for servicing and ventilation.
Protect the pump and piping from freezing temperatures.
Provide other weather protection consistent with the motor enclosure rating. The
maximum ambient temperature for the pump is 40ºC (104ºF).
For installation at altitudes greater than 3,000 feet, the pump selection should be de-
rated due to the difference in barometric pressure. Contact your Goulds distributor for
assistance in selection.
Foundation
The foundation must be able to absorb any vibration and to form a permanent, rigid
support for the pumping unit. Close-coupled units may be installed horizontally,
inclined or vertically with the motor above the pump.
Your GSP pump has been supplied with a rigid base plate with four legs. As supplied,
this is adequate for portable use where the pump may be moved to various places in the
plant based on process requirements.
Optional legs are available with flanged bases which can be used for permanent
mounting to the floor. Hold down bolts should be sunk in concrete and aligned with the
holes in the flanges. When the concrete has dried, tighten nuts to keep the pump firmly
in position.
NOTICE: Do not install with motor below pump. Any leakage or condensation will
affect the motor.
Initial Assembly
Your GSP pump has been shipped with the pump and motor assembled, but the base,
legs and motor cover (if ordered) need to be assembled. Refer to drawings on page 24.
1. Install o-rings into base then install legs using some soapy water or o-ring lubricant.
2. Place the threaded end of one of the legs through the o-ring supplied into the socket
provided on the lower corner of the base plate. Thread the leg into the socket until
tight.
3. Repeat with the other three legs.
4. Place the pump and motor combination onto the base plate so that the holes in
the motor foot align with the holes in the base plate. Insert the motor mounting bolts
through the motor foot and base plate.
5. Place a nut on each of the mounting bolts under the base plate and tighten.
6. If a motor cover has been supplied, place it over the pump so that the suction and
discharge connections protrude out of the front cut out.
