?     Asked on 10/3/2021by Travis

I have a Century 0-173840-23 pump that has been leaking for awhile at the bottom drain screw area. It recently cracked on the housing and I need to replace the volute housing. Can you help me to figure out which housing I need, and whether or not I should also buy a seal kit to stop the drip at the bottom? Pics attached.

Hi Travis, it looks like your Polaris PB4-60 booster pump was made between 1994-2011 (it is easy to tell by the "spines" on the volute) so you need this Polaris Booster Pump Housing Volute for PB460 - P5.  You may also want to replace the O-ring, Bracket To Volute (258) O-Ring when servicing it and the PS-1000 motor shaft seal as well.  Be sure to put some lubricant on the new o-ring to help it last a long time.

Will it fit this pump?

Hello Thomas.  The Zodiac PB4-60 Volute R0536300 is the correct Volute for the PB4-60 model years 2011 - Current.  PB4-60 Volute (INCLUDES DRAIN PLUG W/ ORING) - R0536300     The Zodiac PB4-60 Volute P5 is the correct Volute for the PB4-60 model years 1994 - 2011.  Polaris Booster Pump Housing Volute for PB460 - P5   Visually these volutes are dissimilar.  The R0536300 has curved spines on the volute face radiating from the center, the P5 has straight spins radiating from the center.
