Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
1. Disable the pump's pneumatic air supply.
2. Relieve pressure by slowly loosening the outlet
connection fitting.
General Information
Both the MSA-10 and MSA-100 are air-operated
pumps with an adjustable volume output. They are
designed for use in series progressive oil or grease
lubrication systems.
The lubricant can be supplied to both pumps by either
a gravity feed reservoir or by a pressurized source,
such as a bulk header that exerts up to 500 psi (3.45
MPa, 34.5 bar) at the pump inlet.
NOTE: When connected to a pressurized supply,
backflow to supply must be permitted.
Both the MSA-10 and the MSA-100 are supplied as a
single acting pump and can be field-converted to a
double-acting pump.
NOTE: Typical installation requires a controller
operated, directional air valve since the pump's
pneumatic piston requires venting on the return stroke
to complete a fully cycle.
The pumps come standard with a rupture to
atmosphere indicator rated to 1450 psi (10 MPa, 100
6
bar) and an outlet check valve. Higher pressure rating
rupture discs can be purchased separately. If the
indicator needs repairs due to a ruptured disc:
1. Remove the top nut from the indicator housing.
2. Remove the ruptured disc and replace with a new
disc.
3. Replace the top nut, torque to 5 ft-lb (6.8 N•m).
Mount the Pump

MSA-10 Air Operated Pump
1. Mount the pump to a flat, sturdy surface using two
(2) 5/16 in. screws through the mounting holes (J).
2. Connect the lubrication inlet and outlet lines to the
pump inlet (K) and outlet (L). Do not use PTFE type
tape.
3. Connect the air supply line to the pump air inlet (G),
which is marked "S.A." on the pump body. If a
higher air flow creates a cycle rate that exceeds the
maximum allowed, an inlet restrictor valve is
required (P/N 563072).
•
When using the MSA-10 Air Operated Pump as a
double-acting pump, remove the plastic vent plug
from the double-acting inlet port (H), which is
marked "D.A." on the pump body, and connect a
second air supply line to that inlet.
4. Cycle the pump until all of the air is removed and
the lubricant runs clear at the outlet.
5. Adjust the pump output:
a. Remove the adjustment screw cap (P).
b. Turn the adjustment screw (N):
- Clockwise to reduce output
- Counter-clockwise to increase output
c. When adjusted to desired amount, replace the
adjustment screw cap (P).
