Binks EXEL 41-17045 Manual

The Binks Exel Pumps have horizon-
tally opposed positive displacement
pistons connected to a common
reciprocating air motor piston. The
pneumatically driven piston trips pilot
valves at the end of its travel producing
an air logic signal to shift the spool
valve initiating the opposite stroke.
The mechanically tripped pilot
valves contain no springs. They are
reset by a positive air signal from the
exhaust circuit. The spool valve is
air piloted and contains two exhaust
ports. Both the pilot valves and the
spool valve "un-bolt" as a cartridge,
but can also be disassembled for
repair/service.
There are no external air pilot hoses.
The air logic and exhaust ports are
completely internal. Simply mounting
the spool valve and the pilot valves
assures that the logic circuits are
connected properly.

AIR POWERED PUMP
POSITIVE PRIME RECIPROCATING
HORIZONTALLY OPPOSED 4-BALL PUMP
GENERAL
The "4-Ball" term refers to the two
sets of ball checks. Each "set" has an
inlet and outlet check. In practice,
the inlets are connected by a common
inlet manifold and the outlets are
connected with a common outlet
manifold.
The "4-Ball" concept primes the pump
with the piston always engaging the
seal. Unlike some other horizontally
opposed piston pumps, the piston
does not pull free of the displacement
chamber piston seal to allow prime.
Pulling free of the piston seal for
prime is lost motion. No displace-
ment is possible from the time the
piston pulls free and then re-enters
the seal. The positive displacement
4-Ball concept insures positive
prime and increased displacement
with less energy demands. This
eliminates wasted effort which
requires higher air consumption to
displace a given volume of fluid.
