Features and Benefits

Convertible Jet Pumps - For Shallow Well or Deep Well Applications.

A Flint and Walling CPJ05B 1/2HP convertible jet pump is a type of jet pump that can operate as either a shallow well or a deep well pump, depending on the ejector configuration. Jet pumps are devices that use a jet of water, creating a vacuum and high velocity, which creates higher inlet pressure into the impeller, and creating higher outlet pressures, when drawing from a water source.

A Flint and Walling CPJ05B 1/2HP convertible jet pump has the following features.

• CPJ05B cast iron convertible deepwell pump can provide higher single stage capacities and pressures; as a deepwell pump it can pump from depths to 90' to water table, capacities up to 12.5GPM and create as much as 91PSI shut off pressure. Use chart below for deepwell, 2 pipe ejector, for performance in your application.
• CPJ05B cast iron convertible deepwell pump can provide higher single stage capacities and pressures; as a 2" single pipe ejector (packer system) deepwell pump, it can pump from depths to 150' to water table, capacities up to 16.2GPM and create as much as 108PSI shut off pressure. Use chart below for deepwell, 2" single pipe ejector (packer system), for performance in your application.
• CPJ05B cast iron convertible deepwell pump in shallow well applications, can pump from depths up to 25' to water table, capacities up to 16GPM and create as much as 90PSI shut off pressure. Use chart below for shallow well ejector, for performance in your application.
