Grounding

Warning

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause

serious injury or death if splashed in the

eyes or on the skin, inhaled, or swallowed.

1. Read TOXIC FLUID HAZARD on page 5.

2. Use fluids and solvents which are compatible with

the equipment wetted parts. Refer to the

Technical Data section of all equipment

manuals. Read the fluid and solvent

manufacturer's warnings.

Warning

FIRE AND EXPLOSION HAZARD

This pump must be grounded. Before

operating the pump, ground the system as

explained below. Also, read the section

FIRE AND EXPLOSION HAZARD on

page 5.

Non-Conductive Polypropylene and PVDF

are not conductive.

Attaching the ground wire to the grounding lug will

ground only the air motor. When pumping conductive

flammable fluids, always make sure the fluid has an

electrical path to a true earth ground. Possible

methods of grounding the fluid are through the fluid

containers or piping. Contact your VERDER

Customer Service for assistance in grounding your

system. Never use a non-conductive polypropylene

or a PVDF pump in an explosive atmosphere with

non-conductive flammable fluids as specified by your

local fire protection code. US Code (NFPA 77 Static

Electricity) recommends a conductivity greater than

50 x 10-12 Siemans/meter (ohms/meter) over your

operating temperature range to reduce the hazard of

fire. Consult your fluid supplier to determine the

conductivity or resistivity of your fluid. The resistivity

must be less than 2 x 1012 ohm-centimeters.

819.4486 7

Installation

Grounding (continued)

To reduce the risk of static sparking, ground the pump

and all other equipment used or located in the pumping

area. Check your local electrical code for detailed

grounding instructions for your area and type of

equipment. Ground all of this equipment.

•Pump: Connect a ground wire and clamp as shown

in FIG. 1 Loosen the grounding screw (W). Insert

one end of a 1.5 mm² minimum ground wire (Y)

behind the grounding screw and tighten the screw

securely. Connect the clamp end of the ground wire

to a true earth ground. Order Part No. 819.0157

Ground Wire and Clamp.

NOTE: When pumping conductive flammable fluids

with a non-conductive polypropylene or a PVDF

pump, always ground the entire fluid system.

See the Warning on page 6.

•Air and Fluid hoses: Use only electrically conductive

hoses.

•Air compressor: Follow the manufacturer's

recommendations.

•All solvent pails used when flushing, according to

local code. Use only metal pails, which are

conductive. Do not place the pail on a

non-conductive surface, such as paper or

cardboard, which interrupts the grounding

continuity.

•Fluid supply container: Follow the local code.

Installation

Air Line

1. Install the air line accessories as shown in FIG. 2

Mount these accessories on the wall or on a

bracket. Be sure the air line supplying the

accessories is electrically conductive.

a. Install an air regulator (C) and gauge to control

the fluid pressure. The fluid outlet pressure will

be the same as the setting of the air regulator.

b. Locate one bleed-type master air valve (B)

close to the pump and use it to relieve trapped

air. See the Warning at left. Locate the other

master air valve (E) upstream from all air line

accessories and use it to isolate them during

cleaning and repair.

c. The air line filter (F) removes harmful dirt and

moisture from the compressed air supply.

2. Install an electrically conductive, flexible air hose (A)

between the accessories and the 1/2 npt(f) pump air

inlet (N). See FIG. 2. Use a minimum 13 mm ID air

hose.

3. Screw an air line quick disconnect coupler (D) onto

the end of the air hose (A); be sure the coupler

porting is large enough to not restrict the air flow,

which will affect pump performance. Screw the

mating fitting into the pump air inlet snugly. Do not

connect the coupler (D) to the fitting until you are

ready to operate the pump.

Fig. 2 ______________________________________________________________________________________

Warning

A bleed-type master air valve (B) is required in your

system to relieve air trapped between this valve and

the pump. Trapped air can cause the pump to cycle

unexpectedly, which could result in serious injury,

including splashing in the eyes or on the skin, injury

from moving parts, or contamination from hazardous

fluids. See FIG. 2.

Installation

Mountings

1. Be sure the mounting surface can support the

weight of the pump, hoses, and accessories, as well

as the stress caused during operation.

2. For all mountings, be sure the pump is bolted

directly to the mounting surface.

3. For ease of operation and service, mount the pump

so the air valve cover (2), air inlet, and fluid inlet and

outlet ports are easily accessible.

4. Rubber Foot Mounting Kit 819.4333 is available to

reduce noise and pump movement during

operation.

5. Prolonged exposure to UV radiation will degrade

natural polypropylene components of the pumps. To

prevent potential injury or equipment damage, do

not expose pump or the plastic components to direct

sunlight for prolonged periods.

Fluid Suction Line

1. The pump fluid inlet (R) is a 1-1/2 in. raised face

flange. Refer to Flange Connections on page 10.

2. If the fluid inlet pressure to the pump is more than

25% of the outlet working pressure, the ball check

valves will not close fast enough, resulting in

inefficient pump operation.

3. At inlet fluid pressures greater than 1.05 bar,

diaphragm life will be shortened.

4. See the Technical Data on page 33 for maximum

suction lift (wet and dry).

Fluid Outlet Line

1. The pump fluid outlet (S) is a 1-1/2 in. raised face

flange. Refer to Flange Connections on page 10.

2. Install a fluid drain valve (J) near the fluid outlet. See

the Warning above.

Caution

The pump exhaust air may contain contaminants.

Ventilate to a remote area if the contaminants could

affect your fluid supply. See Air Exhaust Ventilation

on page 12.

Warning

A fluid drain valve (J) is required to relieve pressure in

the hose if it is plugged. The drain valve reduces the

risk of serious injury, including splashing in the eyes

or on the skin, or contamination from hazardous fluids

when relieving pressure. Install the valve close to the

pump fluid outlet. See FIG. 2.
