The Casappa PLP20.20D0-31S1-LGE/GD-N-EL is a published complete Polaris PLP20 external-gear pump execution. Its full order designation is retained as listed for the actual commercial article; it is not assembled from selectable catalogue options.

The listed pump displacement is 21.14 cm³/rev and rotation is clockwise. The article specifies a 15.85mm keyed SAE drive shaft and 1/2"-3/4"BSP port configuration. Polaris pumps use an aluminium body and a pressure-balanced gear arrangement for hydraulic power transmission.

The series technical catalogue provides the Polaris 20 size data and installation guidance. Allowable operating pressure and speed depend on the complete execution and duty conditions and should be checked for the intended installation.
