PH Manual Pump
DESCRIPTION
The single-acting, positive-displacement PH Manual Pump will
deliver 0.15 cubic inches (2.46 cm3) with one full stroke of the
handle. The PH Pump is available with a choice of standard clear
plastic or metal Modu-Flo® reservoirs for either oil or grease.
These reservoirs, with 5, 6, 12, and 20 pint or pound capacities,
can be mounted interchangeably atop the pump.
Modular pump/reservoir design plus built-in features (see
below) enable the PH Manual Pump to be customized for a wide
range of applications. The PH Manual Pump permits increased
standardization with resultant economies in spare parts stocking
and greater employee familiarity with plant or job site lubrication
systems.
This pump is sturdily built with aluminum and steel components
to meet the high standards of performance and quality you expect
from Graco® products. It is a compact, space-saving unit. Even
with an integrally mounted 20-pint or 20-pound capacity reservoir
and bottom-mounted optional outlet valve, it stands only 27.84
inches (70.7 cm) high, is 7.25 inches (18.4 cm) wide and 11.03
inches (28.0 cm) deep. It requires only 24.3 inches clearance
(61.7 cm) from the mounting surface for a full range of handle
pull.
The PH Manual Pump is ideal for use with Trabon® MS divider
valves or MJ divider valves on stationary equipment as well as the
E-Z Luber® Valves on many types of mobile equipment. It comes
complete with 3,000 psi gauge for easy verification of system
operation, and a 2,500 psi automatic relief valve to protect
system components.
FEATURES/ADVANTAGES
• Built-in volume indicator provides easy verification that
lubricant is being delivered to the system and that divider
valves are completing lube cycles.
• Interchangeable reservoirs make it convenient to expand or
contract the lube distribution system, to switch from oil to
grease or from grease to oil – without replacing the entire
system.
• Wide applicability is provided by an optional two- or fouroutlet valve that mounts under the pump outlet. This valve
allows the pump to serve up to four different systems or to
supply one or two separate manual reversing systems.
• Single-acting positive displacement pump design minimizes
the number of moving and wearing parts for extended pump
life and reduced maintenance.
• Built-in automatic relief valve protects system components
from over-pressure.
• Built-in outlet check valve prevents back pressure from
damaging pump and minimizes chance for contaminants to
get into the pump or the lube supply.
• 3,000 psi (207 bar) pressure gauge, shown in photo, provides
a fast check on system status.

OPERATION
As the pump handle (A) is pulled down, the piston (B) moves to
close off the inlet (C) from the reservoir, and to push the lubricant
to and through the passage (D) to the outlet (E) for delivery to the
system.
As the handle returns to its original upright position, the piston
(B) returns to the “prime” position, opening the inlet (C) in
preparation for the next cycle.
The number of pump handle strokes needed to fulfill lube
requirements can be determined by adding up the cubic inches
required by each lube point in the system and dividing the total
by 0.15 (PH Pump output per handle stroke).
To utilize the lube volume indicator, the system master divider
must be designed to provide .200 cu.in. from one outlet during
a complete system cycle. A line should be run from this divider
valve outlet to the return inlet (F) on the PH Pump. This line allows
the lubricant to move the volume indicator plunger (G) to its full
“out” position until the undercut (H) on the plunger is exposed.
This means that 0.200 cubic inches of the oil or grease have
been delivered to the indicator and that the complete system has
cycled. Any excess lubricant will return to the reservoir through
the check valve (I). When the volume indicator is pushed in by the
lube maintenance person, the lubricant it displaces will also be
returned to the reservoir through the check valve.
GREASE RESERVOIR FILL PROCEDURE
Fill the reservoir with grease, free of air, using a suitable fill
pump at the quick disconnect fill plug located in the base of
the reservoir. Note, for first time grease filling, or if the grease
reservoir has been allowed to go empty, open the petcock in
the bottom right side of the reservoir. Slowly begin to fill the
reservoir, allowing air trapped under follower to exhaust out the
open petcock. When grease free of air flows from the petcock,
close petcock and continue to fill the reservoir until follower is at
vent hole in reservoir tube (any remaining air and small amount
of grease will exit vent).
Loosen system mainline connection at pump outlet. Operate
pump until lubricant free of air flows from outlet port. Tighten
mainline connection at pump. Pump is now free of air.
Note, for extreme cases where the pump will not take a prime,
it may be helpful to inject several ounces of heavy oil through
the grease fill quick disconnect. The pump will then prime on
oil pulling the grease behind it. If it becomes necessary to use
this method, all injected oil should be discharged at the loosened
system supply connection along with any air.
Refer to bulletin 12411 (Grease Filler Pump) for manual operated
fill pump.

Two-Outlet Valve —
The two-outlet valve can be used to distribute oil or grease either
to two separate manual systems, or to a single manual reversing
system (Series Reversing or Bi-Flo).
Page 3
Four-Outlet Valve —
The four-outlet valve can be used to supply lubricant to four
separate manual systems or two separate manual reversing
systems.
With both valves, the inlet port directly above the position of the
handle is connected to the outlet port on the bottom of the pump.
This handle also indicates the direction of the flow. The outlet
port can be changed by repositioning the handle under another
outlet. The port opposite the handle is always connected directly
to the return port on the bottom of the pump. When these valves
are used in a reversing system, the ports opposite each other
must be tubed to the delivery lines of the system.
