Selecting your pump:
CAT Plunger Pumps (0.13 – 240 gpm, 100 – 10,000 psi)
Plunger pumps utilize spring-loaded closed and
hydraulically opened inlet and discharge valves
to direct flow through the pump manifold. At the
beginning of the stroke, the plunger displaces
the liquid in the manifold chamber, forcing the
discharge valve open. When the plunger reaches
the end of the stroke, the discharge valve closes.
As the plunger rod begins its backward stroke,
the inlet valve opens to allow more liquid into the
manifold chamber, thereby keeping a smooth
forward flow of liquid.
CAT XP Series Pumps (0.5 – 2 gpm, 100 – 1,000 psi)
In XP series pumps, fluid enters the inlet port
and flows through the drive-end, lubricating the
connecting rods and plunger rods as it passes
to the inlet valves. Both inlet and discharge
valves are spring-loaded closed and hydraulically
opened, similar to plunger pumps, however, they
utilize a flow- through ceramic plunger design.
The continuous forward flow characteristics in
conjunction with the packing design of plunger
pumps result in improved suction capabilities as
well as extended seal life.
CAT Piston Pumps (3.0 – 60 gpm, 100 – 1,500 psi)
The design of the piston pump is for the fluid to
move continually in one, smooth forward direction.
This design allows greater suction capabilities and
reduces the risk of cavitation provided the pump
is properly primed. At the beginning of the stroke,
the mechanically actuated inlet valve (and piston)
will close. As the piston rod moves forward, the
liquid is forced out through the discharge valves.
Simultaneously, the liquid enters the pump inlet
and flows in behind the inlet valve. As the piston
rod begins the backward stroke, the inlet valve
mechanically opens, permitting the liquid to
continue its flow forward through the piston into
the discharge chamber.
.
CAT SF Series Pumps (0.5 – 5 gpm, 100 – 3,500 psi)
In SF series pumps, both the inlet and discharge
valves are spring-loaded closed and hydraulically
opened, similar to plunger pumps, however, they
have a flow- through ceramic plunger design. The
continuous forward flow characteristic of piston
pumps is utilized in conjunction with the packing
design of the plunger pumps. These features give
SF pumps both strong suction capabilities and
higher pressure performances
