ASP FSPO Installation, Operation And Maintenance Instructions

IOMFSPO 0515
Installation, Operation and Maintenance Instructions
Description and Specifications: The Model FSPO is a close-coupled, end suction, single stage, open impeller, back
pullout centrifugal pump. Connections are NPT threaded. All wetted metal pump parts are 304SS or better. Most parts
are forged from stainless steel sheet. The seal plate is made of fiberglass reinforced Ryton. Standard O-rings and
elastomeric seal parts are Buna. Viton and EPR are optional.
flange and a threaded shaft. All pumps use a mechanical seal to prevent leakage around the motor shaft.
Operating limits: The model FSP is designed for a maximum pressure of 50 PSIG, at a maximum temperature limit of
212F. Motor is limited to 20 starts per hour, evenly distributed.
Notice: Upon receipt of this equipment, inspect the carton and the equipment for any damages that might have
occurred during shipment and notify the carrier immediately.
responsibility of American Stainless Pumps. Failure to notify the carrier will place responsibility on the purchaser for any
repairs or damages occurring during shipment.
Safety Instructions: To avoid serious or fatal injury and/or property damage, read and follow all
instructions in this manual. Review all instructions and warnings included in this manual before
attempting any work on this pump or pump/motor assembly. Do not remove or alter any decals.
The motor used to drive this pump is an electrical device connected to a potentially lethal voltage
power source. Take all precautions required when working with or on the motor and its power source,
including but not limited to:
1. Always disconnect and lockout the electrical power source before attempting any connection, maintenance or
repairs. Failure to do so can cause electrical shocks, burns and death.
2. Install, ground and wire motors in accordance with all local and national electrical codes.
3. Install an all leg disconnect switch near the motor for quick access.
4. The electrical supply must match the motor nameplate specifications and the motor must be wired per the wiring
diagram on the motor to match the selected voltage. Incorrect wiring can cause fire and motor damage and will
void the warranty.
5. Most single phase motors and some three phase motors will have automatic thermal protection switches wired in
the motor. These switches will open and stop the motor if the motor overheats. As the motor cools, these switches will
close and start the motor automatically and unexpectedly.
6. Motors that do not have thermal overloads must have a properly sized contactors or magnetic starters and
overload switches (or fuses) in the starter panel. Three phase motors require all leg protection.
7. Use only stranded copper wire to motor and ground. Wire size must limit the maximum voltage drop to 10% of
the motor nameplate voltage at the motor terminals.
8. Three phase motors can rotate in either direction.
(clockwise when looking from the motor end, counter-clockwise when viewed from the pump end). Operating the pump
in the reverse rotation may damage or destroy the pump and motor and voids the warranty.

Installation:

-Locate the pump as near to the liquid source as possible. The pump must be primed with little or no air in the case to
begin operation. The pump must be located below the liquid level when starting. This pump is not self priming.
-Protect the pump and motor from freezing. Although the pump may survive a freeze up, the mechanical seal and O-
Rings will not.
-Allow adequate space around the unit for service and ventilation.
-Units may be installed horizontally, at an angle or vertically with the motor on top. Do not mount the motor below the
pump as leakage from the pump will damage the motor and can cause a shock, burns or death.
-Units mounted horizontally should be located on a flat, rigid surface. Unit may be free standing, but some vibrations
may occur. If attached to a foundation, tighten hold down bolts before connecting the piping.
