Unlike traditional direct-drive pumps, magnetic drive pumps utilize a magnetic coupling which transmits torque from motor to the impeller. This mechanism is especially useful in applications where sudden short-term blockage of the pump impeller or piping may occur from sludge, seaweed and other debris.
About Little Giant Magnetic Drive Pumps
Magnetic drive pumps have a wide range of applications, from handling fresh water to highly corrosive chemicals and liquids with various viscosities. Since pump impeller is connected to the motor by means of a magnetic coupling rather then directly, the pump does not overheat in the event of blockage, allowing it to run without overheating.
Chemical Compatibility
Consult a Chemical Resistance Chart provided by Little Giant to determine compatibility of the pump with a particular chemical type.
“MD” suffix in the part number indicates a magnetic drive pump for Mildly Corrosive liquids, “MD-SC” - Semi-Corrosive, “MD-HC” and “MD-CK” - Highly-Corrosive.
Materials of construction of the above are as follows:
MD series: PolyPropylene (PP) parts.
MD-SC: PolyPropylene, ceramic and Nitrile parts.
MD-HC: PolyPhenylene sulfide (PPS), FlouroElastomer (FKM), carbon and ceramic.
MD-CK: PolyVinyliDene fluoride (PVDF), PolyTetraFluoroEthylene (PTFE), carbon, ceramic and FluoroElastomer (FKM).

Why don't we show the price?
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
