The Flowserve Guardian ANSI Overhung Magnetic Drive Pump 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. The Guardian magnetic drive pump possesses numerous reliability and performance-enhancing features including:
- Rugged silicon carbide bushings and journals
- Proven Mark 3 casing and impeller
- Optimized internal lubrication path
- Available in 18 sizes, the Guardian uses the same casing and reverse vane impeller as the Flowserve Durco Mark 3 ANSI standard pump. This interchangeability of wet end parts provides consistent hydraulic performance and allows pumps to easily be converted from sealed to sealless configurations.

Advantages
- Mark 3 Casing and Impeller: Deliver consistent hydraulic performance and maximum interchangeability.
- 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 from potential damage.
- External Flush Plan: Available with the Guardian to extend the pump’s application range. By introducing a clean, compatible flush fluid or a filtered bypass flush into the containment shell area, the Guardian can handle otherwise difficult process conditions.
