DESCRIPTION
The MSA-10 is an air-operated pump with an ad justable volume
output. It is designed to be used in series progressive oil or grease
lubrication systems. Lubricant can be supplied to the MSA-10
pump by either a gravity feed reservoir or a pressurized source
such as a bulk header that exerts up to 500 psi at the pump inlet.
This pressure handling capability is a result of the pump pistons
valving ac tion which prevents lubricant from flowing into the lube
system when the piston is in the priming position. The MSA-10 is
supplied as a single-acting pump. However, it can easily be field-
converted to double-acting by removing the plastic vent plug from
the double-acting port and installing an air line.
FEATURES
Adjustable lube output, from .040 to .120 cubic inches per •
stroke, permits a broad range of applications.
The MSA-10 is ideal for bulk header lube systems because it •
can handle up to 500 psi inlet pressure.
Single-or double-acting air cylinder provides wide choice of •
controls.
Ability to pump either oil or grease expands the opportunity to •
standardize on the MSA-10 through out the plant or shop.
High pressure relief protection reduces chance of damage to •
the lube system in case of blockage.
Can be piped to standard Trabon reservoirs. (Refer to bulletin •
L12000 for reservoirs.)
OPERATION
When air is supplied in the single-acting port (SA), the pump piston
(A) is moved forward. The lube inlet is closed by the piston (A/B). The
lubricant in the chamber (C) is forced into a channel in the middle
of the piston (B1). An outlet hole (D) from that channel opens into an
undercut (E) on the piston. When the undercut (E) opens to the lube
outlet, the lubricant from the chamber (C) flows, under pressure, to
the lube system. If a blockage occurs in the lube system, the rupture
indicator (not shown) opens and the pressure is vented. When the air
has been vented from the single-acting inlet, the piston return spring
(G) returns the piston to its original position. If the pump is double-
acting, air will be supplied in the double-acting inlet (DA) as air is
vented from the single-acting port.
