Frequently Asked Questions

What is a magnetic drive (mag-drive) pump?

A mag-drive pump uses a sealless design. A drive magnet on the motor shaft turns a driven magnet inside the pump, which spins the impeller. This transfers power without a physical shaft penetrating the housing, eliminating the mechanical seal and making leaks impossible.

What are the main advantages of a sealless pump?

Reliability and safety. By eliminating the mechanical seal, you remove the most common failure point—reducing maintenance, downtime, and emissions. It’s ideal for hazardous, toxic, or corrosive chemicals.

What materials are available?

Thermoplastics such as Polypropylene (PP) and Polyvinylidene Fluoride (PVDF) in DB/SP/MSDB/KC/MSKC, plus ETFE barriers/linings in UCR and polypropylene/ETFE construction in UCP for ANSI-dimensional duties.

What series carry a five-year warranty?

DB and SP series include an industry-leading 5-year warranty. ANSI-dimensional UC lines (UCR/UCP/UC Legacy) follow their respective UC warranty terms.

How do I choose between DB and SP?

DB is a flooded-suction centrifugal with class-leading efficiency. SP is self-priming, capable of lifting from below the pump (to 25 ft) and re-priming without a check valve—ideal for sumps, totes, and over-the-wall pulls.
