The Desmi SA is a self-priming centrifugal pump, and features an open impeller design which consists of a semi-open, non-clogging impeller. This device is responsible for the pump's capability to work on dirty water. The tolerance between the impeller and the pump's wear plate can be adjusted to maintain the pump's quality after working with abrasive fluids.

A mechanical shaft seal, which enables rapid suction and prevents shaft wear and stuffing box tightening, is incorporated into the product. The pump's check valve is placed above the impeller inlet to avoid the loss of priming water in the event of a check valve leakage. A heavy shaft and bearing design results in a long service life, even in case of belt drive.
