PRECAUTIONS
The following precautions should be taken when working with metering pumps.
Please read this section carefully prior to installation.
Protective Clothing
ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or
near your metering pump. Additional precautions should be taken depending on the solution
being pumped. Refer to Safety Data Sheets for the solution being pumped.
Hearing Protection
It is recommended that hearing protection be used if the pump is in an environment where the
time - weighted average sound level (TWA) of 85 decibels is exceeded (as measured on the
A scale-slow response).
Electrical Safety
• Remove power and ensure that it remains OFF while maintaining pump.
•DO NOT FORGET TO CONNECT THE PUMP TO EARTH / GROUND.
• Electric protection of the motor (Thermal protection or by means of fuses) is to correspond
to the rated current indicated on the motor data plate.
Liquid Compatibility
Verify if the materials of construction of the wetted components of your pump are
recommended for the solution (chemical) to be pumped.
Pumps Water “Primed”
All pumps are tested with water at the factory. If your process solution is not compatible with
water, ush the Pump Head Assembly with an appropriate solution before introducing the
process solution.
Plumbing and Electrical Connections
Always adhere to your local plumbing and electrical codes.
Line Depressurization
To reduce the risk of chemical contact during disassembly or maintenance, the suction and
discharge lines should be depressurized before servicing.
Over Pressure Protection
To ensure safe operation of the system it is recommended that some type of safety /
pressure- relief valve be installed to protect the piping and other system components from
damage due to over-pressure.

1.1 DESCRIPTION
Milton Roy Pneumatic Actuators are an accurate
and convenient capacity control device. They are
ideal for plants which currently employ pneumatics
or which need automatic explosion proof pump
capacity adjustment. An optional air control station
can provide local or remote manual adjustment and
an auto / manual selector valve when required.
1.2 PRINCIPLE OF OPERATION
1.2.1 Major Components
Figure 2 illustrates the physical relationships of the
parts and subassemblies described below.
Basically, the operating principle of the Pneumatic
Capacity Control is similar to a conventional
pneumatic valve control, except the regulated
supply air pressure (metered by the Moore Valve
Positioner) is used to pressurize the oil reservoir
which transfers the oil to the back of the Actuator
Piston (1150).
Major components of the Pneumatic Capacity
Control are:
1. The Actuator Piston (1150) is connected to the
pump gear housing and moves to establish and
maintain the pump capacity.
2. The Oil Reservoir (1290).
3. The Transfer Shaft (1220) connected to the
Actuator Piston(1150) to transmit the piston
position to the Range Spring (1420) in the
transparent plastic cylinder (1430).
4. The Moore Products Valve Positioner (1440)
monitors the Actuator Piston position as a
function of the applied instrument air signal
and develops the necessary metered supply air
pressure required to reposition or maintain the
position of the piston.
1.2.2 Operating Description
The Actuator Piston incorporates the differential
area principle with the supply air pressure
(80-100 psi) (551-689 kPa) applied directly to
the small area of the piston. This establishes a
constant preload through the piston transfer shaft
and range spring to the Moore Valve positioner.
Hydraulic pressure is not used on the preload
side of the actuator piston, since the pressure is
constant and the hydraulic snubbing effect is not
required in this direction.
In order to move the Actuator Piston in both
directions, the force on the opposite side of the
piston must be variable to a higher and lower value
than the preload force developed by the supply
pressure acting on the small area side of the piston.
The Moore Valve Positioner compares the applied
instrument air signal with the Actuator Piston
position, as indicated by the range spring force,
and adjusts the air pressure applied to the oil in
the reservoir. Since the oil reservoir is connected
directly to the large area side of the Actuator Piston,
a force proportional to the oil pressure is obtained.
This force opposes the xed force caused by the
supply air pressure on the small area side of the
piston.
SECTION 1 - DESCRIPTION

2Instruction Manual
SECTION 1 - DESCRIPTION
In the Milroyal®pump, the pulsating plunger thrust
load is applied directly onto the capacity control,
through the adapter shaft (1320) which must be
capable of opposing this pulsating force without
moving. Air, which is compressible, cannot be used
directly to load the large area side of the Actuator
piston to oppose this pulsating load. Therefore,
the air pressure established by the Moore Valve
Positioner is changed to an equivalent hydraulic
pressure. To accomplish this, the oil in the reservoir
is pressurized by the air pressure from the Moore
Valve Positioner and the oil is routed internally from
the reservoir through the transfer shaft to the large
side of the Actuator Piston. To effectively prevent
movement of the stroke adjustment when the
plunger thrust load is applied, an oil check valve
is required to prevent ow back from the hydraulic
cylinder(1240) to the reservoir. This valve action
is obtained where the actuator shaft (1100) bears
against the Actuator Piston.
The Actuator Shaft retention in the Actuator Piston
allows for approximately 0.005 to 0.020 inch
(0.127 to 5.080 mm) lost motion and is spring
loaded for Actuator shaft-piston contact. On the
suction stroke the thrust reversal overcomes the
spring force and separated the surfaces to open the
oil passage between the reservoir and the hydraulic
piston-cylinder, thus permitting readjustment of
the piston position. Then at the end of the suction
stroke, these surfaces are brought into contact to
close this passage and create a closed hydraulic
cylinder with an incompressible uid to hold the
Actuator Piston position on the next pressure
stroke.
When the oil pressure in the transfer shaft passage
is 5-10 psi (34.5-68.9 kPa) higher than the oil in the
hydraulic cylinder, the spring loaded check valve
in the adapter shaft will open to supply oil to the
hydraulic cylinder. This oil valve bypass is used
to increase the speed of response when reducing
stroke position and to provide for control movement
when the pump is not operating.
A small quantity of oil is continuously bled from the
top of the hydraulic cylinder and routed internally
to the bottom of the oil reservoir. This bleed ow
also tends to increase the speed of response when
increasing stroke position.
The Transfer Shaft (1220) is extended through
the reservoir into the transparent Plastic Cylinder
(1430) so that this shaft is also used to transmit
the position of the Actuator Piston to the Range
Spring (1430). The transparent cylinder provides
a direct visual indication of the actual position of
the actuator piston by comparing the position of the
ring groove in the Range Spring Piston (1380) with
the percent capacity scale on the outside diameter
of the cylinder.
The complete Pneumatic Capacity Control
assembly is mounted on the pump using an
adapter ange clamped on the boss of the housing.
The position of the adapter is adjusted at the factory
to establish the correct stroke calibration and the
control assembly can be removed for servicing in
the eld without disturbing this.
1.3 MODEL PRODUCT CODING
Milroyal®B pumps can be ordered with or without
a pneumatic capacity control (PCC) unit already
attached. If the PCC is ordered with the pump, it
is indicated in the pump model code by a “PN” in
the 11th & 12th or 13th & 14th positions. The pump
model code can be found on the pump data plate,

SECTION 1 - DESCRIPTION

4Instruction Manual
2.1 INTRODUCTION
The Pneumatic Capacity Control is an integral
accessory designed for mounting on the
Milroyal®B frame pumps in place of the manual
micrometer adjustment. Two air line connections
are required to place the unit into operation:
1. The instrument air signal.
2. The supply air pressure regulated to 80 to
100 psi (551 to 689 kPa). As for all precision
pneumatic devices, clean, ltered, dry air should
be used at all times.
These connections are also shown in Figures 1
& 2, pages 12-13. Factory installed controls have
been adjusted for operation between 0 and 100%
capacity for the specied instrument air signal
range. For eld installation, refer to Section 3,
“Maintenance”.
2.2 UNPACKING
Units are shipped Free on Board (FOB) factory
and the title passes to the customer when the
carrier signs for receipt of the unit. In the event
that damages occur during shipment, it is the
responsibility of the customer to notify the carrier
immediately and to le a damage claim.
Carefully examine the shipping crate upon receipt
from the carrier to be sure there is no obvious
damage to the contents. Open the crate carefully so
accessory items fastened to the inside of the crate
will not be damaged or lost. Examine all material
inside crate and check against packing list to be
sure that all items are accounted for and intact.
2.3 SAFETY PRECAUTIONS
When installing, operating, and maintaining
the Pneumatic Capacity Control, keep safety
considerations foremost. Use proper tools,
protective clothing, and eye protection when
working on the equipment and install the equipment
with a view toward ensuring safe operation.
Follow the instructions in this manual and take
additional safety measures appropriate to the liquid
being pumped. Be extremely careful in the presence
of hazardous substances (e.g., corrosives, toxics,
solvents, acids, caustics, ammables etc.).
2.4 FIELD INSTALLATION (RETROFIT)
This Pneumatic Capacity Control can be installed
on pumps in the field to replace the manual
micrometer stroke adjustment. It will be necessary
to disassemble the micrometer adjustment
in order to disconnect and remove the stroke
adjustment lead screw from the pump gear housing.
In preparation, turn the micrometer to zero stroke
setting. Refer to the applicable Milroyal®Instruction
Manual which was furnished with the pump for the
disassembly instructions. Manuals will be supplied
by the factory when the request is accompanied
with the Pump Serial Number.
SECTION 2 - INSTALLATION

5Instruction Manual
1. After removing the micrometer stroke adjustment
screw (1110) from the pump housing, clean
and degrease the threads in the boss inside
the pump housing and also the threads of the
new adapter bushing (1470) supplied. Apply
a medium grade of Loctite®compound to the
adapter threads and install the adapter in the
adjustment boss bore from outside the housing
to obtain complete thread engagement.
2. Prepare to install the capacity control assembly
by slightly loosening (nger tight) the six hex
head screws (1350) and one socket screw
(1360) in the mounting collar. Place O-ring (70)
in the adapter shaft ring groove and apply a
generous lm of seal lubricant on the O-ring.
3. Install the capacity control assembly on the
pump boss using care to guide the adapter
shaft (1320) through the adapter bushing
and to compress the O-ring into the boss.
Position the mounting color within 1/8”(3 mm)
of the housing.
4. Inside the pump housing, reassemble the lead
screw keys to engage the groove in the end
of the capacity control adapter shaft (1320)
and install the locking set screws in the gear
housing. Remove the set screw (1540) because
it may collapse the threaded adapter bushing.
Rotate the worm shaft to position the crank arm
at the top of its travel.
5. Refill the pump drive casing with oil and
complete the reassembly of the pump.
6. Complete the connection of the signal and
supply pressure air lines to the capacity control
and fill the oil reservoir as outlined in the
installation section. Tighten the mounting collar
clamping socket screw (1360).
7. Apply supply pressure and use signal pressure
to position the control at 0% capacity as
indicated by the percent capacity scale on the
transparent cylinder. Loosen the mounting collar
clamping socket screw (1360) and move the
mounting collar and control on the pump boss
until the gear housing is positioned for zero
plunger travel to correspond to 0% capacity
setting of the control. The zero stroke position
can be determined by rotating the input shaft
by hand (turn the coupling between input
shaft and motor through open bottom of motor
mounting) so that the crank rotates through a full
revolution, checking the crosshead in “lateral”
area for a movement. At “zero” stroke there will
be no perceptible movement of the crosshead
when crank goes through a full revolution.
8. Tighten the mounting collar clamp screw (1360)
and the six mounting screws (1350). Remove
set screw (1540) from top of mounting collar
(1330) and spot drill through the set screw
hole in mounting collar with a 1/4” (6.35 mm)
diameter drill to a depth of approximately 1/16”
(1.5 mm). Blow out chips from drilling. Install
and tighten half dog set screw.
9. Actuate the control through the full stroke range
to bleed all air from the hydraulic cylinder.
Then check the calibration of the control
% capacity indication against the plunger stroke
at zero and full stroke positions.

SECTION 2 - INSTALLATION
2.5 OIL FILLING INSTRUCTIONS
Although all pump mounted stroke controls are
factory lled with hydraulic oil and operated before
shipment, it is advisable to check the oil level in
the hydraulic oil reservoir before placing unit in
operation. This level can be checked, and lled if
required in the following manner:
1. Adjust instrument air signal to position the piston
in the pump-mounted plastic cylinder to its 100%
position.
2. Shut OFF the supply air, then shut OFF the
instrument air to the unit. The 100% position
will be maintained.
3. Remove the ller plug (Drawing 102209500020
on page 12) on the top of the reservoir and
note the 1/8”(3 mm) diameter tube located in
the opening below the plug. When lling the
reservoir do not pour oil onto or into this small
tube.
4. Fill the reservoir with any light oil (SAE 5 or
SAE 10) (32 to 72 kPa) until the oil level is
within one inch (25 mm) below the top edge of
the small tube.
5. Install the oil ll plug and readjust air supply to
80-100 psi (551-689 kPa).
6. Adjust the control between the maximum and
minimum instrument air signals several times to
allow the oil to enter and ll the chamber behind
the piston and the system passages.
7. Repeat rst ve steps to insure that the reservoir
is lled to within 1” (25 mm) of the top of the
small tube when control is at the 100% capacity
position.

7Instruction Manual
SECTION 3 - OPERATION
3.1 OPERATION

4.2 RETURNING UNITS TO THE FACTORY
PCC units will not be accepted for repair without a
Return Material Authorization, available from the
Factory Repair Department. If the PCC is being
returned attached to a Milroyal®B pump, process
liquid should be ushed from the pump liquid end
and oil should be drained from the pump housing
before the pump is shipped. Label the unit clearly
to indicate the liquid being pumped.
NOTE:
Federal law prohibits handling of equipment that
is not accompanied by an OSHA Safety Data
Sheet (SDS). A completed SDS must be packed
in the shipping crate if the PCC is returned
attached to a pump. These safety precautions
will aid the troubleshooting and repair procedure
and preclude serious injury to repair personnel
from hazardous residue in pump liquid end.
All inquiries or parts orders should be addressed
to your local Milton Roy representative or sent to:
www.miltonroy.com.
4.3 REMOVAL OF CONTROL UNIT
Before removing the Control from the pump, it is
necessary to position the control at 100% capacity
by applying proper instrument air signal (usually
15 psi (103 kPa)). Then:
1. Shut OFF supply air pressure and disconnect
line at the control.
2. Shut OFF instrument air pressure and disconnect
line at the control.
3. Remove the oil drain plug (1460) (see drawing
on page 12) from the bottom of the reservoir
and collect oil in a shallow pan.
4. Remove Control mounting screws (1350)
and pull Control away from mounting collar
(1330) until adapter shafts (1100 & 1320) are
exposed.
5. Unbend locking tabs on lock ring (1310) located
against at actuating shaft (1100).
SECTION 4 - MAINTENANCE

9Instruction Manual
SECTION 4 - MAINTENANCE
6. Use wrench on ats of both shafts (1100 &
1320) to unscrew shaft connection which
has approximately one inch threaded
engagement.
NOTE:
Provide adequate support for the control
assembly as the shaft connection is being
unscrewed to prevent binding or damage to
the threads.
NOTE:
An alternate method for removing the control
from the pump is by disengaging the clevis
keys from the groove in the adapter (1320),
located in the gear housing, and remove as
an assembly. This eliminates the need for the
difcult procedure of breaking the Loctite®joint
and bending the tab on the locking washer, but
will require draining the oil from the pump drive
casing.
7. The control assembly can now be removed
from the pump and should be taken to the work
bench for further inspection, disassembly or
checkout.
4.4 DISASSEMBLY
1. Disconnect the plastic tube (1520) at supply.
2. Pressure tee tting. Remove the nuts (1450)
from the mounting stud (1410). The Moore
Products Valve Positioner and the transparent
cylinder (1430) can now be removed from the
mounting studs. Before the transparent cylinder
is slipped OFF (see Figure 1), the range spring
and spring seat (1420) should be taken out.
3. Remove the screw (1390), holding the range
spring piston (1380) to transfer shaft (1220).
Remove the range spring piston (1380) from
the transfer shaft (1220).
4. Remove the reservoir-cylinder screws (1370)
and then pull the reservoir housing (1290) and
end plate (1260) OFF over the transfer shaft
(1220).
5. The Actuator Piston assembly (1150) with
the transfer shaft (1220) and actuating shaft
(1100) can now be removed from the cylinder
(1430).
6. To remove the transfer shaft from the piston,
remove the retaining ring (1230) with right angle
retaining ring pliers. Discard the O-ring (1210)
under the transfer shaft anged if a replacement
ring is available.
7. To remove the adapter shaft (1320) from the
actuator piston (1150), remove the retaining ring
(1200) with right angle retaining ring pliers.
THE SPRING (1180) UNDER THE
RING (D) MUST BE RESTRAINED
AS THE RETAINING RING IS REMOVED AND THEN THE
COMPRESSION RELEASED SLOWLY.
8. Remove and discard the O-ring (1140) on the
adapter shaft (1320).
9. To remove the check valve seat (1130), install a
hex head 10-24 screw in each of three tapped
holes in face of seat. Alternately tighten each
screw to pull the seat out of the adapter shaft.
The nylon poppet (1120) and spring (1110) are
loose and will be free after seat is removed.
This completes the disassembly of the Pneumatic
Capacity Control. To reassemble the Pneumatic
