Manual Oil or Grease Pumps

MLS Mechanical Lube Pumps are designed for automatic lubrication of machinery where machine motion can be used as the power source for the pump. The mechanical action is transmitted directly to the pump piston, combining compactness and simplicity. A small adjustable shot of lubricant is discharged on each stroke of the pump. Actuation rate should be limited to 50 strokes per minute for oil and 25 strokes per minute for grease. A mechanical force of about 75 lbs on the roller will develop 2000 psi lube pressure. Pumps will easily develop 3000 psi if required. All MLS Pumps are equipped with a high pressure relief assembly. Its replaceable rupture disc protects the pump and automatically signals blockage (high pressure) in the system, should it occur. Pumps are equipped with blow-out discs (Part No. 509-294-000- 2050 psi). If higher or lower disc bursting pressure is required, see Bulletin 15401 for part numbers. If desired, a pressure gauge (sold separately) can be teed into the main outlet (See Bulletin 15326). Also available is a high pressure blow-out switch (Part No. 511- 573-000), which can be used to actuate a fault light or horn.
