Finish Thompson SP10 SERIES SELF-PRIMING - Manual (Page 4)

4
CAUTION: Never start or operate with a closed suction valve.
WARNING
: Operation without priming or against a closed discharge valve can result in high temperatures that can
result in injury or damage to pump components.
CAUTION: Always provide adequate NPSHa (net positive suction head available). It is recommended to provide at
least 2 feet (61 cm) above the NPSHr (net positive suction head required).
CAUTION: If pump is used on variable speed drive, do not exceed 60 Hz.
SP10 Capabilities
Maximum Working Pressure: 80 psi (5.5 bar)
Maximum Temperature:
Polypropylene: 180º F (82º C); PVDF: 220º F (104º C)
NOTE: Maximum temperature is application dependent. Consult a chemical resistance guide
or the chemical manufacturer for chemical compatibility and temperature limits.
Maximum Lift: 25 feet (7.6 meters) with 4.18” and 4” diameter impellers. See the chart below for maximum lift
for other impeller diameters.

NOTE: Lift was determined on fresh, cold water with 1” and 1 ½” Schedule 40 pipe. Specific
gravity affects lift capability. Divide maximum lift from chart above by the specific gravity to
determine equivalent maximum lift.
Solids: Maximum particle size is 100 microns for slurries and 1/64” (.4 mm) for infrequent particles.
Maximum hardness is 80 HS. Maximum concentration is 10% by weight. If solids are being
pumped, it is
recommended the pump has either ceramic or, for best results, silicon carbide components.
Pumping solids may lead to increased wear.
NOTE: While the pump is capable of being used in sump applications, it is NOT a trash pump. Care must be taken to ensure that debris
and foreign objects do not enter the pump or damage may result. Suggest using a 1” strainer basket with 1/32” (.8 mm) perforations
or 1 1/2” strainer basket with 1/8” (3.2 mm) perforations. Regular strainer basket maintenance is required to prevent plugging and
decrease in NPSHa so not to starve and damage the pump.
Minimum Allowable Flow Rate
Do not allow the flow rate to drop below the minimum flow rate listed in the chart below.
WARNING:
The pump and associated components are heavy. Failure to properly support the pump during lifting and
movement could result in serious injury or damage to the pump and components.
CAUTION: This pump should never be started without the 0.6 US gallon /77 oz. ( 2.7 liters) of priming fluid in the
housing. If the pump has a PTFE, ceramic or silicon carbide bushing, IT CANNOT BE RUN DRY WITHOUT CAUSING
DAMAGE TO THE PUMP. However, the pump can operate without liquid in the housing if the pump has a carbon bushing.
The exact length of time the pump can operate dry with a carbon bushing varies with operating conditions and environment.
Maximum Sound Level:
