WARNING

Installation

6 3A4586E

Installation

Grounding

Grounding is an electrical connection between a metal

vessel, pump, or motor and a true earth ground.

Motor: Electrical cords must be connected to outlets

with electrical ground.

Pump: Ensure that the ground screw provided with the

pump is connected to a true earth ground. Insert one

end of a 14 AWG minimum ground wire behind the

ground screw and tighten the screw securely. Connect

the clamp end of the grounding wire to a true earth

ground. A ground wire and clamp, Part 238909, is avail-

able from your Graco distributor.

Fluid hoses: use only electrically conductive hoses with

a maximum of 500 ft. (150 m) combined hose length to

ensure grounding continuity. Check electrical resistance

of hoses. If total resistance to ground exceeds 25 meg-

ohms, replace hose immediately.

Material supply container: follow local code.

Container(s) that receive material: follow local code.

To maintain grounding continuity when flushing or

relieving pressure: hold metal part of the dispense

valve firmly to the side of a grounded metal pail, then

trigger the valve.

Mounting

1. Remove the pump and motor from packaging.

2. Inspect all contents for damage.

3. Install the motor with pump lower:

a. On pumps using the 17N668 motor, hang the

pump using the included motor hanger (302)

using adequate hardware, following local code.

Torque the motor hanger to 30-36 ft-lb (41-49

N-m).

b. On pumps using the 17N666 or 17N667 motor,

attach motor to pump by tightening the motor

nut on the pump.

The equipment must be grounded to reduce the risk of

static sparking and electric shock. Electric or static

sparking can cause fumes to ignite or explode.

Improper grounding can cause electric shock. Ground-

ing provides an escape wire for the electric current.

To avoid injury from a falling pump, model 25C422 or

25C782, check the connections on the motor hanger

(302) before using the motor hanger to lift the pump.

NOTICE

To avoid damaging the pump, do not overtighten the

mounting hardware.

10 3A4586E

Operation

1. Use closed top drum or other cover to prevent pos-

sible contamination.

2. Once the pump is fully cleaned, assembled, and all

connections are securely fastened, insert the pump

into the drum or tank.

3. It is recommended to attach a suitable hose or pipe

to the pump discharge.

4. If you opt to use a hose:

a. Ensure that the hose meets the pump discharge

pressure requirements. It is recommended to

use a hose that is rated 4x the pump discharge

pressure.

b. Fasten the hose to the hose barb with a suitable

hose clamp that exceeds the pump discharge

pressure. A hose barb fitting kit, part 25C502, is

available from your Graco distributor.

5. Variable speed pumps should be started at approxi-

mately half speed according to the dial settings.

Turn the motor to the ON position. Throttle flow to

desired output pressure by varying the potentiome-

ter (motors 17N666 and 17N667) or VFD frequency,

if applicable on motor 17N668.

6. After use, flush and clean the pump. Then store the

pump vertically.

• Moving parts can pinch, cut or amputate fingers

and other body parts. Keep your hands and fingers

away from the mechanical seal viewing window on

models 25C422 or 25C782 during operation and

whenever the pump is connected to a power

source. Disconnect power before moving.

• Do not use these pumps for the transfer of

flammable or combustible products or in an

environment where flammable or combustible

fumes are present.

• Do not clean or flush the pump with flammable or

combustible fluids.

• Progressive cavity pumps are positive displace-

ment pumps and should never be operated

against shut-off elements such as nozzles, valves,

etc. Failure to comply may result in excessive

pressure build resulting in serious injury and pump

damage.

NOTICE

• Never allow the pump to run dry of fluid. A dry

pump will possibly damage itself.

• Progressive cavity pumps 25C420, 25C421,

25C780, and 25C781 are recommended for inter-

mittent duty use only to prevent premature motor

wear. (i.e., 30 minute intervals with a 10 minute

cooling off period). For continuous duty applica-

tions, Graco recommends using models 25C422 or

25C782.
