Sealless Magnetic Drive Pumps for Biofiltration/Odor Control Applications
The chemicals involved in biofiltration and odor control are some of the harshest substances used in any industry. These applications require robust systems to withstand harsh environments and safely deliver reliable results. Finish Thompson’s durable sealless magnetic drive pumps are designed to meet the challenges of these high-demand applications.
Typical Applications
- Control odors at sewage treatment plants
- Pump dilute solutions of sodium hypochlorite and sodium hydroxide
- Convert hydrogen sulfide to sulfur
- Provide flow and pressure to spray nozzles

Pump Details
DB Series, SP Series
Magnetically coupled, sealless centrifugal pumps. Finish Thompson DB Series and SP Series pumps are designed from the ground up to pump corrosive chemicals in electroplating and anodizing facilities.
Features
- No mechanical seal – Powerful rare earth magnetic drive system eliminates the troublesome mechanical seal.
- Corrosion resistant – Engineered for the most aggressive liquids, manufactured from polypropylene or PVDF.
- Run dry ability – Makes them less prone to operator error or system upset.
- Self-priming option – SP Series pumps can lift fluid from as deep as 25 feet (7.6 meters) below the pump or can pull liquid out of the top of a tank eliminating through-the-sidewall bulkhead fittings.
MSDB Series
Multi-stage sealless centrifugal pumps enable specification of smaller, less expensive pumps for low flow/high head applications. They feature sealless mag drive design.
Features
- Multi-stage design – to produce much higher heads at lower flow rates than similarly sized single-stage pumps.
- Performance – Heads up to 300 feet (91.5 meters) are possible, with a minimum flow rate of one gpm (0.23 m3/hr) and a maximum flow rate of 69 gpm (15.7 m3/hr).
- No mechanical seal – Powerful rare earth magnetic drive system eliminates the troublesome mechanical seal.
UC Series
Engineered for extreme reliability in the most extreme chemical processing applications, Finish Thompson’s ULTRAChem® pumps are magnetically driven, ANSI dimensional pumps. They are constructed from tough ductile iron with ETFE lining for superior corrosion resistance.
Features
- Sealless design – Powerful neodymium magnets drive the impeller through a carbon-filled ETFE lined barrier for dependable, leak-free operation.
- Fully supported shaft and self-aligning dual bushings – designed for optimum alignment to prevent premature wear.
- Complete encapsulation of inner drive magnets in ETFE – for ultimate corrosion protection.
