Installation Operation & Maintenance Instructions
Model SSP & SSPC
Description and Specifications : The Model SSP is a close coupled, end suction, single stage, open-impeller,
back-pullout centrifugal pump. The model SSPC is the enclosed impeller version of the same pump. Connections are
NPT threaded. All wetted metal pump parts are 18-8, 304SS, or better. Most parts are formed from stainless steel
sheet. O-rings and elastomeric seal parts are Buna (Viton, EPR are optional). Motors are NEMA 56J frame, with a C-
Face mounting flange and a threaded shaft. All pumps use a mechanical seal to prevent leakage around the motor
shaft.
Operating limits: The models SSP & SSPC are designed for 75-PSIG operating pressure at 212 deg. F., with the
standard Type-6, carbon vs. ceramic with buna-n elastomers mechanical seal, and a maximum temperature limit of 250
deg. F., with a Type-21 mechanical seal with viton elastomers. The motor is limited to 20 starts per hour, evenly
distributed.
Notice: Upon receipt of this equipment, inspect the carton and the equipment for any dam-
ages that might have occurred during shipment and notify the carrier immediately.
Damage
that occurs during shipment is not the 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 which do not have thermal overloads must have a properly sized contractor 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. The pump will operate properly only in one direction
(clockwise when looking from the motor end, counterclockwise when viewed from the pump end). Operat-
ing the pump in the reverse rotation may damage or destroy the pump and motor and voids the
warranty.
