The Binks Exel Pumps have horizontally opposed positive
displacement pistons connected to a common reciprocat-
ing air motor piston. The air driven piston trips the pilot
valves at the end of its travel producing an air logic signal
to shift a spool valve, thus initiating the opposite stroke.
The mechanically tripped pilot valves are reset by a pos-
itive air signal from the exhaust circuit. Additionally, the
pilot valves are spring assisted to ensure consistent, reli-
able operation. The spool valve is 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.
The air logic and exhaust ports are completely internal.
Simply mounting the spool valve and the pilot valves
ensures that the logic circuits are connected properly.
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 by 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 displacement is possible from the time the piston
pulls free and then re-enters the seal. The positive
displacement “4-Ball” concept ensures 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.
