Installation

3A6831A 7

Installation

Grounding

Pump: ground through electrically conductive pneu-

matic and fluid lines.

Pneumatic and fluid lines: use only electrically con-

ductive lines.

Air compressor: follow manufacturer’s recommenda-

tions.

Fluid supply container: follow local code.

Required Accessories

Install the following required accessories in the order

shown in FIG. 1, using adapters as necessary.

Pneumatic Line

•Bleed-type master pneumatic valve (D): required

in your system to relieve air/gas trapped between it

and the pneumatic motor when the valve is closed.

• Be sure the valve is easily accessible from the

pump and located downstream from the pneu-

matic regulator.

•Pump pneumatic regulator (E): to control pump

speed and outlet pressure. Locate it close to the

pump.

•Pneumatic line filter (C): removes harmful dirt and

moisture from compressed air/gas supply.

•Second bleed-type pneumatic valve (pneumatic

shutoff valve) (B): isolates pneumatic line acces-

sories for servicing. Locate upstream from all other

pneumatic line accessories.

Fluid Line

•Fluid filter (Y-Strainer) (included in G): with a 60

mesh (250 micron) stainless steel element to filter

particles from the fluid before in reaches the pump.

•Fluid shutoff valve (H): shuts off fluid flow.

•Pressure relief valve (J): overload protection.

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

Flush the Equipment, page 11.

If using a flammable gas to drive the motor, to reduce

the risk of fire or explosion, route the exhaust away

from all sources of ignition. See Route Exhaust to

Remote Location on page 9.

NOTE: A small amount of the exhaust is not recover-

able, and will vent to atmosphere at the pump. How-

ever, a 100% Exhaust Capture Kit, B32651, is

available.

To reduce the risk of injury from ejected ice, do not

operate the motor without a plumbed exhaust line or

muffler installed.

Installation must comply with all local codes and regu-

lations.

The equipment must be grounded to reduce the risk

of static sparking. Static sparking can cause fumes to

ignite or explode. Grounding provides an escape wire

for the electric current.

Installation

Typical Installation

FIG. 1 is an example of an installation with a Python

XL-DA25 chemical injection pump. Your installation may

differ from what is shown here. (See Required Acces-

sories, page 7.) The Python XL-DA25 pump (F) and

pneumatic needle valve (B) are the only components in

FIG. 1 supplied by Graco. All other components are sup-

plied by customer.

Mount the Pump and Connect

Chemical Supply

The pump can be bolted to a wall or skid by the attached

bracket.

NOTE: The pump must always be mounted vertically.

If you have an application, or mounting configuration,

that requires installation in a manner different than

depicted in FIG. 1, please contact your Graco distributor

for assistance.

NOTE: A y-strainer (G) or chemical filter is required

before the pump inlet. This will keep any debris from the

tank from reaching the pump seals. Fluid filters are

available from Graco.

1. Mount the pump (F) and connect the fluid inlet

line (K).

FIG. 1:

Installation

3A6831A 9

Connect Pneumatic Supply

1. Install the pneumatic regulator (E) and gauge to

control the inlet pressure. See Models on page 3for

your model’s maximum pneumatic pressure.

NOTE: If less than 100 psi supply pressure is used, the

pump’s maximum output pressure will be decreased

proportionally.

Minimum Pneumatic Pressure can be found by first find-

ing the table that corresponds to the plunger size (see

Minimum Pneumatic Pressures by Fluid Plunger

Size and Outlet Pressures on page 10). Next, using

the column that corresponds to the pneumatic motor

size, find the row equal to or slightly greater than the

outlet pressure of the pump. The value is the Minimum

Pneumatic Pressure required to achieve the fluid outlet

pressure.

2. Install a pneumatic line filter (C) to keep debris from

affecting pump performance and to increase pump

life.

NOTE: Keep the needle valve (B) closed at this point to

keep the pump from operating without fluid, which mini-

mizes seal wear.

3. Attach a pneumatic line to the 1/4 in. female NPT

port on the needle valve (B).

Route Exhaust to Remote

Location

Replace the muffler (18) with a pneumatic line to route

exhaust to a remote location.

Connect Chemical Outlet

1. Connect a fluid line from the pump outlet port (M) to

the injection point.

2. Install a fluid pressure relief valve (J) on the outlet

side of the pump.

NOTE: A pressure relief valve is available from Graco

and can be connected back to the tank or directly to the

inlet side of the pump. See Kits and Accessories on

page 35.

3. Set the pressure relief valve at or below the maxi-

mum working pressure of the pump.

NOTICE

Due to the operational design of the pneumatic valve,

a small amount of the exhaust is not recoverable, and

will vent to atmosphere. However, a 100% Exhaust

Capture Kit, B32651, is available.

In the event of an injection line blockage, to reduce the

risk of skin injection and damage to the pump, ensure

the pressure relief valve is set at or below the maxi-

mum working pressure of the pump.
