Guardian ANSI Overhung, Magnetic Drive Pump

The Flowserve Guardian is a horizontal, magnetic drive pump, compliant with ANSI B73.1M dimensional standards. The Guardian is designed for simplicity and reliability for emission-free service requirements. The Guardian pump uses a Mark 3 casing and impeller for proven, consistent hydraulic performance.

Mark 3 Casing and Impeller deliver consistent hydraulic performance and maximum interchangeability.

Exclusive Reverse Vane Impeller provides constant inner bearing lubrication, predictable thrust characteristics, and lowest average NPSHR.

Optimized Internal Lubrication Path designed to provide bearing lubrication before heat removal from containment area.

Silicon Carbide Bushings and Journals with double spiral grooves for superior lubrication and bearing life.

Precise Running Clearances protect the containment shell form potential damage.
