Part # 5110-10F
Manufacturer Code SPX1621C
Dimensions 5.2" X 1.8"
Alternate Part #'s HAY1014188, SP1621C, SPX1621C
Impeller 2.5 THP - SPX1621C
20+ year old Hayward pumps use:
SP-1621-C impeller (old style with threaded phenolic hub rather than brass insert)
Are the SPX versions of these parts direct replacements for old SP part numbers?
Full set of seals,
Q1 replacement motor. We have three pumps with 2HP 50Hz motors. Planning to substitute 2.5HP 60Hz version with same dimensions if 50Hz not available.
thank you and best regards,
Hi, Robert. Yes, the SPX part # is the same and will work as a replacement. As for the seals, they're all located in the Hayward Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT. The replacement 50hz replacement motor is not available. You can substitute the original motor with the UST1252 motor.
Is this interchangeable with impeller SP 1650-C?
Hi. I was not able to locate any info on the SP1650C impeller so I can't confirm if the SP1621C impeller can be used as a replacement. I would recommend that you double check the part number or provide us with the pump model number for verification.
Will this fit model Number K48M2N111?
Hi Joe, The Impeller is specific to the Pump not the motor. In order for us to find the correct impeller we would need the make and model of the wet end of the pump.
