Magnetic Drive Pumps

Features:

• Leakproof, seal-less magnetic drive

• No maintenance due to seal wear

• No seal friction to reduce motor horsepower

• Only chemical resistant materials are in contact with ﬂ uids

• Dynamically balanced drive magnet for long motor

bearing life

• Magnetic coupling design acts as a clutch to eliminate

motor burnout and overloading under adverse conditions

• Pumping heads are easily rotated, cleaned or serviced

with no special tool requirements

• Spindle shaft is supported at both ends to prevent

impeller damage during start-up and stop of pump

• Magnet housing acts as an insulator to prevent motor

heat from being transferred to the ﬂ uid being pumped

• Wide selections of materials for the pump wetted

components to provide the best chemical resistance

• All threaded intake and discharge ports are USA

(American) standard taper pipe threads (NPT). PTFE tape

is provided with PPS pumping head models.

• The MD-HC Series models have “run-dry” capability

• All motors feature thermal overload protection

• All motors are rated for continuous duty

Four series with increasing chemical resistance

NOTE: Consult your local distributor or Franklin Electric about applications with ambient temperatures, speci c

gravities and viscosities beyond the ranges shown for pumps in this catalog.

MD Series

Designed for pumping mild solutions such as those found in ﬁ lm

processing and most neutral chemicals with temperatures up to 66˚C.

Materials of construction include glass-ﬁ lled polypropylene, titanium,

nitrile and a barium-ferrite magnet.

MD-SC Series

Designed to pump mild to strong acids found in electroplating

applications with temperatures up to 66˚C. Materials of construction

include glass-ﬁ lled polypropylene, ceramic and nitrile.

MD-HC Series

Designed to pump strong acids and alkaline solutions including sulfuric,

nitric and hydrochloric acid with temperatures up to 93˚C. In addition,

the HC series offers “Run Dry” protection. Materials of construction

include glass-ﬁ lled polyphenylene sulﬁ de (PPS), ceramic, Fluoroelastomer

(FKM) and pure carbon.

MD-CK Series

Designed to pump highly corrosive acids and halogenated hydrocarbons

such as hydroﬂ uoric acid and ultrapure water solutions. Maximum ﬂ uid

temperature is 93˚ C. Materials of construction include carbon-ﬁ lled PVDF,

ceramic, Fluoroelastomer (FKM) and carbon PTFE.

Little Giant’s comprehensive line of magnetic drive pumps is designed

for circulation of acids, alkalis, solvents, brine, plating solutions, sterile

solutions, and other special ﬂ uids, for use in environments such as hospitals,

chemical companies, photo labs, dry cleaning plants, car washes, machine

shops, laboratories, manufacturing plants, print shops and wineries.
