Model SSP & SSPC
Installation Operation & Maintenance Instructions
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. Standard mechanical seal faces are carbon and
ceramic, with silicon carbide also available.
Operating limits
The models SSP & SSPC are designed for a 125-psig operating pressure at 212 deg. F., with the standard Type-16,
Carbon vs. Ceramic faces with Buna-N elastomers mechanical seal. A maximum temperature limit of 250 deg. F is
possible with Viton elastomers. The motor is limited to 20 starts per hour, evenly distributed. Minimum flows are 5% of the
best efficiency operating point. These pumps are not designed for use with hazardous liquids or gasses.

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.
Damage that occurs during
shipment is not the responsibility of American Stainless Pumps. Failure to notify the carrier will place responsibility on the

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.
- Page 3 American Stainless Pumps, Inc. Rotation The models SSP & SSPC will operate properly only in one direction (clockwise when looking from the motor end, and counterclockwise when viewed from the pump end). Three phase motors can rotate in either direction. Single phase Operating the pump in reverse rotation may cause the motors normally only rotate in the proper direction.
- Page 4 8. Model SSP Only: There should be several spacing washers behind the impeller. These spacers locate the open impeller vanes close to the case for efficient operation. Measure the thickness of this stack of spacers for future reference.
- Page 5 7. Model SSP Only: Place the necessary number and thickness of impeller spacer/washers onto the threaded portion of the shaft. If you are not changing the impeller or the motor, use the same batch of spacer/washers you removed when disassembling the pump.
- Page 6 See SSP Performance Notes for impeller shimming discussion www.aspumps.com/products/ssp/3500- rpm/ssp_perf_notes.htm Properly setting the impeller to case clearance is the most critical factor in determining the SSP’s performance. You will get maximum performance and efficiency (and maximum amp draw) with near to zero clearance. Factory standard clearance is 8 to 12 mil.
