Sethco PMSP Magnetic Drive, Self Priming Centrifugal Pumps

Sethco, PMSP, Magnetic Drive, Self Priming, Centrifugal PumpsThe Sethco PMSP Magnetic Drive, Self Priming Pumps feature Polypropylene construction for use in corrosive liquid applications.

Priming the pump is easy. The operator simply fills the priming chamber with the liquid to be pumped and turns the pump on. Other features include the ability to run dry after initial priming, easy to disassemble design and an internal basket strainer to prevent foreign objects from entering pump.

Corrosion resistant, the pump is recommended for acids, alkalies, caustics, sea water, solvents and many other difficult applications.

Leakproof, Seal-less Construction
No shaft seal is used or required on these magnetically driven pumps. The superior seal-less, magnetic-drive design provides a reliable, smooth running, vibration-free pump that delivers high flow and pressure.

Self Priming Capability
This feature is extremely advantageous when pumping from elevations lower than the pump, such as emptying sumps. The 7-1/2 HP pump has the ability to lift liquid up to 20 feet in 3 minutes or less.

Excellent Chemical Resistance
The wetted components of these rugged seal-less pumps are available in your choice of Polypropylene or all PVDF. Polypropylene is glass reinforced and PVDF is carbon reinforced for added strength and reliability. These materials offer broad corrosion resistance to acids, alkalies, caustics, bleaches, sea water, solvents and many harsh environments.

All pumps include a 99.5% Alumina ceramic shaft and thrust washers. High purity carbon bearings are
standard with RytonŽ or silicone carbide available where required. Viton o-rings are standard on all pumps, while teflon and EDPM are available. There is no metal contact with the liquid being pumped.

Run Dry Capability
Once a self priming model has been initially primed, it is possible for it to run without any additional fluid. This insures that the pump will not be damaged if the liquid flow is interrupted for any reason.

Designed for Reliability
Among its many features is its unique impeller/driven magnet design. The two are separate distinct pieces so that one can be replaced without having to purchase the other. This feature also reduces the load on the front bearing and thrust washer.

Easy to Maintain
In the event a pump should ever need service, the limited number of parts allows for easy disassembly, inspection and maintenance without any special tools or talent. The motor can be separated from the pump housing without difficulty. Magnetic coupling design acts as a clutch to eliminate motor burnout
and overloading under adverse conditions. Magnet housing acts as an insulator to prevent motor heat from being transferred to the fluid being pumped.
