Dura-Flo Pumps with NXT™Air Motors Part No. Matrix
Check your pump’s identification plate (ID) for the 6-digit part number of your
pump. Use the following matrix to define the construction of your pump, based
on the six digits. For example, Pump Part No. P16MSErepresents the
pump (P), pressure ratio (16:1), low noise exhaust motor with DataTrak™(M),
stainless steel construction (S), and 4 leather/1 ptfe packing configuration (E).
To order replacement parts, see Parts section starting on page 20. The digits
in the matrix do not correspond to the Ref. Nos. in the Parts drawings and lists.

Warnings
311828F 7
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-
tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just
a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS forms from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu-
facturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.

Warnings
8311828F
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read MSDS’s to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
• Always wear impervious gloves when spraying or cleaning equipment.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection
WARNING

Installation
311828F 9
Installation
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: Use the ground screw (GS) and lockwasher on
the motor to attach a 244524 ground wire (Y). Tighten
the screw securely. Connect the other end of the ground
wire to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor or hydraulic power supply: follow
manufacturer’s recommendations.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing, page 15.
Mounting Accessories
See Dimensions, page 24 and Mounting Hole Lay-
outs, page 25.
FIG. 1 shows an air-powered system and FIG. 2 shows a
hydraulic-powered system.
Hoses
See FIG. 1 and FIG. 2. Be sure all hoses are properly
sized and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have
spring guards on both ends. Use a whip hose (P) and a
swivel (R) between the main fluid hose (N) and the
gun/valve (S) to allow freer gun/valve movement.

Installation

Air Line Accessories
For air-powered pumps, install the following accessories
in the order shown in FIG. 1, using adapters as neces-
sary.
•Bleed-type master air valve (E): required in your
system to relieve air trapped between it and the air
motor when the valve is closed. Be sure the valve is
easily accessible from the pump and located down-
stream from the air regulator.
•Pump air regulator (F): to control pump speed and
outlet pressure. Locate it close to the pump.
•Air line filter (J): removes harmful dirt and moisture
from compressed air supply.
•Second bleed-type air valve (K): isolates air line
accessories for servicing. Locate upstream from all
other air line accessories.
Hydraulic Line Accessories
For hydraulic-powered pumps, install the following
accessories in the order shown in FIG. 2, using adapters
as necessary.
• Use a minimum 13 mm (1/2 in.) ID supply line (C),
and a minimum 22 mm (7/8 in.) ID return line (D).
The motor has a 3/4 npt(f) hydraulic oil supply fitting,
and a 1 in. npt(f) hydraulic oil return fitting.
•Supply line shutoff valve (U) isolates the pump for
service.
•Fluid pressure gauge (F) monitors hydraulic oil
pressure to the motor to avoid overpressurizing the
motor or displacement pump.
•Pressure- and temperature-compensated flow
control valve (G) prevents the motor from running
too fast and possibly damaging itself.
•Pressure reducing valve (H) with a drain line (E)
runs directly to the hydraulic return line (D).
•Accumulator (J) reduces the hammering effect
caused by the motor reversing direction.
•Return line shutoff valve (V) isolates the pump for
service.
• Be sure your hydraulic power supply is equipped
with a suction filter to the hydraulic pump and a sys-
