Ballast pump cartridge. Can be used to replace the cartridge of a ballast pump without replacing the entire pump, which cheaper and easier than buying a whole new pump if you don't need to. Works with the 750, 800, and 1100 GPH pumps.
Our cartridges are modified to Malibu's specifications with a plug and play delphi connector, which makes installation quicker and easier. This feature will not be found on the majority of cartridges sold online. If you don't need the connector you can simply remove it.
The best way to identify if you need the cartridge or the whole pump is to determine if it's leaking or not. If the pump is leaking, it's likely the housing has cracked and you will need a whole new pump; otherwise, you'll likely just need the cartridge.
