DESCRIPTION AND SPECIFICATIONS
• The SPM/SPH Series embraces a line of end suction
single stage, self-priming centrifugal pumps for lawn
sprinkling, HVAC systems, and general water transfer.
• Casing is cast iron construction with tapped openings
provided for vacuum gauge and casing drain.
• Impeller is bronze, enclosed design, balanced for smooth
operation and keyed to motor shaft.
• ALL motors are NEMA standard, 3500 RPM, open drip
proof or TEFC enclosure.
ENGINEERING DATA
• Maximum Liquid Temperature: 160º F (71º C)
• Starts per hour: 20 – evenly distributed.
PIPING
• Pump MUST be installed horizontally on a solid flat
surface, with discharge on top.
• Allow adequate space for servicing and ventilation.
Protect the unit from weather and water damage due to
rain or flooding or freezing temperatures.
• Piping should be no smaller than the suction and dis-
charge connections and kept as short as possible, avoid-
ing unnecessary fittings to minimize friction losses.
• All piping MUST be independently supported and MUST
NOT place any piping loads on the pump.
NOTICE: DO NOT FORCE PIPING INTO PLACE AT
PUMP SUCTION AND DISCHARGE
CONNECTIONS.
• The use of Teflon™ tape, or equivalent, is recommended
for ALL pipe joints.
• All pipe joints MUST be airtight.
PIPING – SUCTION
• Total suction lift, including elevation and pipe friction loss,
should not exceed 25 feet.
• Install an airtight union in the suction line close to the
pump. See Figure 1.

• Installation of a foot valve at the liquid source, or a check
valve after the pump discharge, is recommended.
NOTICE: FOR INSTALLATIONS WITH LONG SUCTION
PIPING, BOTH A FOOT VALVE AND A
CHECK VALVE ARE RECOMMENDED.
• To avoid air pockets, no part of the piping should be
above the pump suction connection and piping should
slope upward from liquid source.
• For installations with long suction piping, fill the suction
pipe with water before connecting to pump.
• To ensure proper level installation of the pump utilize
included shims (13K248-0.75" or 13K346-1.75") under
motor feet.
