DIAPHRAGM PUMP 
Diaphragm pumps handle industrial process and waste fluids, solvents, light-bodied adhesives and printing inks.
System Description:
Need to handle light fluid transfer for autos, trucks, busses? What about construction and mining equipment? Our new diaphragm pumps handle the job, plus industrial process and waste fluids, solvents, and light-bodied adhesives and printing inks, too. Lincoln—your “one-stop shop” for fluid transfer.
Lincoln’s two new diaphragm pumps (Models 85353 and 85354) are
rugged, with a choice of Santoprene™ or Teflon™ diaphragm and check balls that make them compatible with a wide range of materials. The pumps seal even better. They’re also easier to service because parts subject to normal wear are modular and can be replaced without disconnecting the pump. The pumps are self-priming, explosion-proof, and reliable, but Lincoln’s new diaphragm pumps are also much more.
By complementing our reciprocating pump lines, the new pumps reinforce Lincoln’s position as a “one-stop shop” for a wide range of vehicle service, manufacturing process and fluid handling applications.
Features & Benefits:
- Compatible with a wide range of materials
- Better seal, easier servicing due to bolted design
