DAB Micra 50M Pump

A submersible, multi-stage, centrifugal electric pump for 3” or larger wells, tanks, or cisterns. These pumps have an extensive range of applications for lifting and distribution in civil and industrial water systems, filling of pressure vessels and tanks, pressurization and irrigation systems. Install in vertical position or, in case of horizontal installation, ensure the minimum load on the thrust assembly.

Pump clean liquids, free of solids and abrasives, that are non-viscous, nonaggressive, and chemically neutral, with properties similar to water.

About the pump

Pump and motor are directly coupled with a rigid coupling. Impellers and thrust rings in Noryl and diffusers are self-lubricating polyacetyl. Pump liner, shaft and coupling, strainer and cable sheath are stainless steel. Base support and head are brass, with check valve incorporated in the head.

About the motor

Submersible asynchronous two-pole motor made entirely of AISI 304 stainless steel with brass bearings. Copper squirrel cage rotor mounted on Kingsbury thrust block. Cooling of the thrust bearing assembly and the bushings is provided by water, thereby eliminating the risk of contamination. Canned-type stator in an airtight casing made of AISI 304L stainless steel. The thermal protector with automatic reset is included with the motor.
