Specifications

The available product data provides dimensions in both inches and centimetres. The listed inch measurements are a length of 16.6 inches and a height of 4.6 inches. The additional metric measurements are a length of 60 cm, a width of 20 cm, and a depth of 10 cm. These values are reproduced as provided in the product data; the source does not specify whether the metric measurements refer to the component itself or its packaged dimensions.

The available specification data does not identify the pump material, connection thread size, mounting hardware, seal configuration, or included components. These parameters are therefore not specified for this product description.
