Installation

Grounding

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. Grounding provides an escape wire for the electric current.

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 available 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 megohms, replace hose immediately.

Mounting

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.

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.

NOTICE

To avoid damaging the pump, do not overtighten the mounting hardware.

Operation

use a hose that is rated 4x the pump discharge pressure.

• 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 displacement 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.

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 approximately half speed according to the dial settings. Turn the motor to the ON position. Throttle flow to desired output pressure by varying the potentiometer (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.

• Progressive cavity pumps 25C420, 25C421, 25C780, and 25C781 are recommended for intermittent duty use only to prevent premature motor wear. (i.e., 30 minute intervals with a 10 minute cooling off period). For continuous duty applications, Graco recommends using models 25C422 or 25C782.

1. Use closed top drum or other cover to prevent possible 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

Operation

Initial Configuration (17N668 motor with Graco VFD)

For initial setup, review at least the following menus to configure the system to suit your particular needs. See your VFD manual for detailed information about each menu option and about default settings.

1. VFD Parameter P103 controls the maximum frequency (the top end of manual speed) of running your pump. This setting is NOT your operating frequency. It is the maximum limit of operating frequency.

2. VFD Parameter P108 controls motor overload. Set so that the VFD cannot supply more current to the motor than it can handle. The formula for the set value is: X = Motor current rating x 100/VFD output current rating

3. VFD Parameter P171 controls the absolute current limit. It is set to allow for momentary spikes in current above the limit set in P108. A spike occurs, for example, when the roller passes over the double hose section. This parameter is usually set for 2 to 3 times the value on menu P108, which was calculated in the previous step.
