Technical Specifications Part Number: ZBR39320 Application: Pump body kit for booster-pump systems Includes: Pump housing + drain plug (other internal components sold separately) Compatible Pump Series: Boost-Rite universal booster pump line Applications & Compatibility This body kit is ideal for pool professionals or homeowners who find their booster pump body cracked, leaking or otherwise compromised. By installing the ZBR39320 kit you restore the pump’s structural integrity and avoid full-pump replacement. Confirm that your pump model is part of the Boost-Rite series before purchase. Installation Instructions Turn off power to the pump and lock out the circuit before servicing. Drain the pump body if required, disconnect all plumbing and motor connections. Remove the old body, clean all sealing surfaces and remove debris or scale build-up. Install the new ZBR39320 housing, route the motor coupling correctly, secure bolts and ensure the drain plug is properly seated. Reconnect plumbing, restore power and test the pump for leaks, proper flow and quiet operation. Troubleshooting Leak from pump body seam: Ensure bolts are tightened evenly, check gasket or O-ring condition and confirm the body is properly aligned with motor and volute. Pump body flexing or cracking: Verify installation alignment, confirm correct torque of mounting hardware and ensure the housing material is appropriate for the chemicals in your system. Pump performance drop after installation: Inspect volute and impeller clearance, verify motor alignment and ensure no air is being drawn into the housing at joints. Maintenance Tip During annual service, check the drain plug for tightness and inspect around the housing for hairline cracks or discoloration. Replacing the body with the ZBR39320 kit before major failure will help prevent downtime and extend the life of your Booster pump system.
