Abstract
The disclosed invention improves on self-priming centrifugal pumps. The improvements facilitate ease of maintenance by allowing the vacuum pulley belt to be changed without the need to disassemble the centrifugal pump to access the vacuum pulley belt. Additionally, issues with float valves becoming restricted leading to loss of prime conditions can be corrected with a disclosed invention.
