Installation (All Pumps)

Mount the Pump

This pump can be mounted on a floor stand, cart, wall
bracket, or drum. The floor stand shown in Figs. 4 and
5 is Part. No. 220581.

Instructions for mounting the pump are supplied with
the mounting accessory.

Plumbing

Most displacement pumps have a 1–1/2 in. npt(f) fluid
inlet and a 1 in. npt(f) fluid outlet. Models 240606,
240607, 240608, 240609, 240610, 240611, 240612,
and 240613, have a 1–1/2 in. bsp(f) fluid inlet and a
1–1/4 in. bsp(f) fluid outlet.

Use a minimum 25 mm (1 in.) diameter pipe or hose
between the pump outlet and any supply line accesso­ries. Use a minimum 38 mm (1–1/2 in.) diameter pipe
or hose between the mix tanks and pump inlet.

Pumps With Tri-Clamp Adapters

Displacement Pumps 240606, 240608, 240610, and
240612 include tri-clamp adapters which allow sanitary
pipe to be connected to the pump inlet and outlet.
Refer to Fig. 2.

Install a 1–1/2 in. tri-clamp gasket (GG, not supplied)
in the groove of the tri-clamp adapter (LL). Mate the
tri-clamp adapter with the sanitary pipe and secure
with two clamps (HH), bolts (JJ), and nuts (KK) (not
supplied). Install the bolts in opposite directions.

Installation (All Pumps)

Non-Circulating Systems

In non-circulating systems with a fluid outlet that can
be closed off (causing the pump to stall), install a fluid
pressure relief valve (AA) and a return line (BB) lead­ing back to the fluid supply line (C). See Fig. 3.

WARNING

COMPONENT RUPTURE HAZARD

The pressure relief valve reduces the
risk of the pump overpressurizing if the

piston seal is worn and leaking, and the
fluid outlet is closed off. Install the valve so the ar­row on its body matches the direction of fluid flow.

Do not install a fluid shutoff valve in the fluid line
between the pump outlet (DD) and the pump inlet
(CC). Doing so defeats the purpose of the pressure
relief valve if the shutoff valve is closed, resulting in
pump overpressurization. Overpressurization can
cause the pump or components to rupture, result­ing in serious injury and property damage.

Installation (Air-Powered Pumps)

Air Line to Motor

WARNING

A bleed-type master air valve (M) is required in
your system, to help reduce the risk of serious
injury including splashing fluid in the eyes or on the
skin, and injury from moving parts if you are adjust­ing or repairing the pump.

The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
Order Part No. 113333.

1. The air line lubricator (N) automatically lubricates
the air motor to prevent corrosion. See Fig. 4.

2. The bleed-type master air valve (M) relieves air
trapped between itself and the motor, when the
valve is closed. Install one valve close to the
pump, downstream from the air regulator. Install a
second bleed valve upstream from all other air line
accessories, to isolate the accessories for servic­ing.

5. The air filter (K) removes harmful dirt and moisture
from the compressed air supply.

6. The air supply line (J) must be large enough to
supply the proper volume of air to the motor.

Fluid Line from Pump

WARNING

A fluid drain valve (U) is required in your system, to
help reduce the risk of serious injury including
splashing in the eyes or on the skin if the pump
cycles unexpectedly.

Locate one valve downstream from the pump outlet
and another valve downstream from the surge tank
(G). These drain valves are used to relieve fluid
pressure in the pump and surge tank during shut­down.

1. The surge tank (G) reduces fluid surging to pre­vent backflow into the pump. Mounting instructions
are supplied with the tank.

3. The air regulator (L) controls pump speed.

4. The pump runaway valve (P) shuts off the air to
the pump if the pump speed exceeds your
pre-adjusted setting. Running a pump too fast can
damage it.

2. The shutoff valves (D) before and after the surge
tank, and between each mix tank and the pump
fluid inlet, isolate these components for servicing.

3. Be sure the supply line (C) between the pump and
mix tanks (A) is level.

Hydraulic Power Supply

CAUTION

The Hydraulic Power Supply must be kept clean at
all times to avoid damage to the motor and hydraulic
power supply.

1. Blow out hydraulic lines with air and flush thor­oughly before connection to the motor.

2. Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.

1. Be sure the power supply can provide sufficient
power to the motor.

2. Be sure the power supply is equipped with a
suction filter to the hydraulic pump.

Hydraulic Supply to Motor

Hydraulic Return from Motor

NOTE: The motor’s hydraulic outlet is 7/8 in., 37_

flare. Use a minimum 16 mm (5/8 in.) ID hydraulic
return line (K).

1. The return line shutoff valve (R) isolates the motor
when servicing the system.

CAUTION

To avoid damage to the pump, never use the return
line shutoff valve to control the hydraulic flow. Do not
install any flow control devices on the hydraulic re­turn line.

2. The 10 micron size return filter (J) removes resi­due from the hydraulic fluid to help keep the sys­tem running smoothly.

Fluid Line from Pump

WARNING

NOTE: The motor’s hydraulic inlet is 3/4 in., 37_ flare.

Use a minimum 13 mm (1/2 in.) ID hydraulic supply
line (L).

1. The supply line shutoff valve (S) isolates the motor
when servicing the system. See Fig. 5.

2. The hydraulic fluid pressure gauge (Q) monitors
the hydraulic oil pressure to the motor. This helps
avoid overpressurizing the motor or displacement
pump.

3. The pressure- and temperature-compensated flow
control valve (T) prevents the motor from running
too fast, which can damage it.

4. The pressure reducing valve (P) which has a drain
line (M) running to the return line (K), controls the
hydraulic pressure to the motor.

A fluid drain valve (U) is required in your system, to
help reduce the risk of serious injury including
splashing in the eyes or on the skin if the pump
cycles unexpectedly.

Locate one valve downstream from the pump outlet
and another valve downstream from the surge tank
(G). These drain valves are used to relieve fluid
pressure in the pump and surge tank during shut­down.

1. The surge tank (G) reduces fluid surging to pre­vent backflow into the pump. Mounting instructions
are supplied with the tank.

2. The shutoff valves (D) before and after the surge
tank, and between each mix tank and the pump
fluid inlet, isolate these components for servicing.

3. Be sure the supply line (C) between the pump and
mix tanks (A) is level.

Operation (All Pumps)

Before You Start the Pump

Read and follow all instruction manuals, labels and
tags supplied with this pump and with all the accesso­ries you add to the system, before operating the sys­tem.

Flush the Pump Before First Use

The pump was tested in lightweight oil. If the oil will
contaminate the fluid you are pumping, flush it out with
a compatible solvent.

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to
prevent the system from starting or spraying acci­dentally. To reduce the risk of an injury from acci­dental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Proce-
dure whenever you:

D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray nozzle.

1. Shut off the power to the pump.

2. In an air-powered system, close the air regulator
(L) and close the bleed-type master air valve (M).

3. In a hydraulic-powered system, close the hy­draulic supply line shutoff valve (S) first, then the
return line shutoff valve (R). In a multi-pump
system, do this at each pump to isolate the pumps.

4. Close the fluid shutoff valves from the supply
tanks.

5. Trigger the gun at the last gun station to relieve
fluid pressure. Maintain firm metal-to-metal contact
between the gun and a grounded waste pail.
Repeat for all gun stations.

6. Open all drain valves (U) to relieve fluid pressure
which may be trapped in the pump or hose.

If you suspect that pressure is not fully relieved after
following the steps above, wrap a fitting near the pump
outlet with a rag, and slowly and carefully loosen the
fitting to relieve pressure. Be careful to protect your
eyes from splashing.

Operation (Air-Powered Pumps)

Starting and Adjusting the Pump

1. Charge the surge tank, if you are using one. See
the separate instruction manual, 307707.

2. Open all fluid shutoff valves (D).

3. Open the dispensing valve/spray gun at the last
gun station and keep it open while starting the
pump.

4. Open the bleed-type master air valves (M).

5. Adjust the air regulator (L) to the minimum pres­sure necessary for the pump to cycle slowly.

6. When fluid is flowing smoothly from the gun,
release the gun trigger.

7. One at a time, open any other guns in the system
to purge air from the lines.

8. Adjust the pump runaway valve (P) according to
the instructions supplied with it.

9. Adjust the lubricator (N) according to the instruc­tions supplied with it.

NOTE: In a circulating system, the pump operates
continuously until the power supply is shut off. In a
direct supply system, the pump starts when the gun/
valve is opened, and stops when the gun/valve is
closed.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing
your system, which could cause
component rupture and serious injury,

never exceed the specified maximum air input
pressure to the pump (see Technical Data on

pages 50–56).

Shutdown

WARNING

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 15.

Relieve the pressure.

16 308793

Operation (Hydraulic-Powered Pumps)

Starting and Adjusting the Pump

1. Charge the surge tank, if you are using one. See
the separate instruction manual, 307707.

2. Open all fluid shutoff valves (D).

3. Turn on the hydraulic power supply.

4. Open the flow control valve (T) all the way.

5. Open the return line shutoff valve (R) first, then
open the supply line shutoff valve (S).

6. Open the dispensing valve/spray gun at the last
gun station and keep it open while starting the
pump.

7. Adjust the pressure reducing valve (P) until you
get the desired fluid pressure.

8. When fluid is flowing smoothly from the gun,
release the gun trigger.

9. One at a time, open any other guns in the system
to purge air from the lines.

10. With a gun triggered open (dead-end systems
only) or with the pump running in a circulating
system, count the cycle rate of the pump for one
minute. Close the flow control valve (T) until the
cycle rate drops to below the desired cycle rate.

12. Release the gun trigger.

NOTE: In a circulating system, the pump operates
continuously until the power supply is shut off. In a
direct supply system, the pump starts when the gun/
valve is opened, and stops when the gun/valve is
closed.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of overpressurizing
your system, which could cause
component rupture and serious injury,

never exceed the specified maximum hydraulic
input pressure to the pump (see Technical Data

on pages 57–59).

Shutdown

WARNING

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 15.

11. Open the flow control valve (T) slowly until the
cycle rate and fluid pressure return to the desired
level. This method of setting the hydraulic controls
ensures proper pump operation and prevents
pump runaway and damage if the fluid supply runs
dry.

Relieve the pressure.

Always shut off the supply line shutoff valve (S) first,
and then the return line shutoff valve (R). This is to
prevent overpressurizing the motor or its seals.

308793 17

Maintenance

Preventive Maintenance Schedule

The operating conditions of your particular system
determine how often maintenance is required. Estab­lish a preventive maintenance schedule by recording
when and what kind of maintenance is needed, and
then determine a regular schedule for checking your
system. Your maintenance schedule should include the
following:

Flushing

WARNING

FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
AND EXPLOSION HAZARD on page

4. Be sure the entire system and flush­ing pails are properly grounded. Refer to
Grounding on page 7.

1. Flush before shutting down the system for an
extended period of time.

2. Flush before repairing the pump, if possible.

Excessive Leaking at Throat

If you see excessive leaking at the throat, and tighten­ing the packing nut does not help, replace the throat
packings. See page 27.

Senator Pump

Shown

1

21

3. Flush before the fluid you are pumping can dry out,
settle or set up in the pump and hoses.

Packing Nut Tightness

The packing nut (21) should be tight enough to stop
leakage, but no tighter. Overtightening compresses
and damages the packings, and may cause the pump
to leak, reducing performance. See Fig. 6.

To check the adjustment of the packing nut, first re­lieve fluid pressure. If you have a torque wrench,
tighten the packing nut to 34–40 NSm (25–30 ft–lb).

Maintenance

Air Line Lubricator

Keep properly filled for automatic air motor lubrication.

Air Line Filter

Drain and clean as necessary.

Hydraulic Power Supply Check

Carefully follow the hydraulic power supply manufac­turer’s recommendations on reservoir and filter clean­ing, and periodic changes of hydraulic fluid.

Mix Tank Volume

Don’t let the mix tank run dry. When the tank is empty,
the pump demands more power as it tries to suck in
some fluid. This causes the pump to run too fast,
which can seriously damage the pump.

Stop the Pump at the Bottom of Its Stroke

WARNING

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 15.

Whenever you stop the pump for any reason, relieve
the pressure. Stop the pump on the downstroke,
before the air motor changes over.

CAUTION

Failure to stop the pump at the bottom of its stroke
allows fluid to dry on the piston rod, which can cause
damage to the throat packings when the pump is
restarted.

WARNING

COMPONENT RUPTURE HAZARD

The relief valve seat (6) must be in­stalled at the fluid intake, as shown in

Fig. 15. The relief valve relieves pres­sure trapped in the pump cylinder when the pump
is shut off, and reduces the risk of pump overpres­surization. The seat cannot relieve pressure if
installed in any other position.

6. Place the intake housing (10) on the lower pump
housing (11). Install the lockwashers (8) and
capscrews (9). Torque to 34–40 NSm (25–30 ft-lb).
See Fig. 15.

7. Place the intake housing (10) in a vise. Place one
o-ring (2*) in each side of the lower pump housing
(11), where the tubes (3) sit. Place o-rings (2*) in
the grooves at each end of the tubes. Place a
gasket (18*) in both the upper and lower housings
(1 and 11). Position the tubes and cylinder (4) in
the lower housing (11).

8. Lubricate the inside of the cylinder (4). Slide the
piston assembly into the cylinder.

9. On stainless steel pumps, install the o-ring (39{)
on the throat cartridge (38), then screw the throat
cartridge into the upper pump housing (1).

lips facing down: one UHMWPE (20{), one leather
(25{), UHMWPE, leather, UHMWPE. Install the
female gland (26{). Install three v-packings with
the lips facing up: UHMWPE, leather, UHMWPE.
Install the other male gland (19{). Install the
packing nut (21) finger-tight.

4. Install the relief valve intake seat (6) in the left side
of the lower housing (11), as viewed in Fig. 15 (the
arrow on label 35 points to the correct location).
The pin (P) on the seat must point up into the
housing. The pin limits the positioning of the seat,
ensuring that the vent hole (V) is not blocked by
part of the housing. Refer to Fig. 14.

5. Install the intake seat without a relief valve (34) in
the right side of the lower housing (11).

NOTE: The seats (6 and 34) are not reversible; the

well on the tubes and cylinder. Install the bolts and
lockwashers (14) from the lower pump housing
(11). As you tighten the bolts into the upper hous­ing (1), they will draw the housings firmly onto the
tubes and cylinders. Tighten the bolts uniformly
and torque to 34–40 NSm (25–30 ft-lb).

12. On stainless steel pumps, torque the cartridge
(38) to 135 NSm (100 ft-lb).

13. Torque the packing nut (21) to 34–40 NSm (25–30
ft-lb).

14. Place a ball (23), seat (24) and gasket (7*) in each
side of the outlet housing (22). Install the outlet
housing on the upper pump housing (1). Note that
the flatter side of the housing faces the outside
edge of the pump. Install the lockwashers (8) and
screws (9), and torque to 34–40 NSm (25–30 ft-lb).
