Installation
Tightening Threaded Fasteners Before First
Use
After unpacking the pump, and before using it for the first
time, check and retorque all external fasteners. See Service
for torque specifications. See Torque Sequence, page 17,
for torque sequence. After the first day of operation, retorque
the fasteners again. Although pump use varies, a general
guideline is to retorque fasteners every two months.
Use a compatible thread sealant on all male threads. Tighten
all connections firmly to avoid air or fluid leaks.
Caution
To avoid pump damage, do not overtighten the fittings to the
pump.
Grounding
Warning
This pump must be grounded. Before you
operate the pump, ground the system as
explained below. Also read the section FIRE
AND EXPLOSION HAZARD on page 3.
The acetal pump contains stainless steel
fibers which make the wetted parts conduc-
tive. Attaching the ground wire to one of the
grounding locations grounds the wetted
parts.
The polypropylene and Kynarr pumps are not conduc-
tive. When you pump conductive flammable fluids, al-
ways ground the entire fluid system. Make sure the fluid
has an electrical path to a true earth ground, see Fig 1.
Never use a polypropylene or Kynarr pump with non-con-
ductive flammable fluids as specified by your local fire
protection code.
US Code (NFPA 77 Static Electricity) recommends a con-
ductivity greater than 50 x 10
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
12
must be less than 2 x 10
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.
Acetal Pump Grounding Instructions
For polypropylene and KynarR pumps, see the warning
above.
Ground all of this equipment.
Pump: Connect a ground wire (A) and clamp, Part No.
819.0157. See Fig. 1. The pump grounding locations are on
the manifold between the inlet and outlet ports. Use the nut
(B) and bolt (C) that are provided with the pump, and install
as follows:

ohm-centimeters.
1.
Place the nut in the nut catcher on the underside of the
manifold.
2.
Insert the bolt through the loop end of the ground wire.
3.
Insert the bolt through the hole on the pump manifold
and tighten it into the nut that you positioned in step 1.
4.
Connect the clamp end of the ground wire to a true earth
ground.

Air and fluid hoses: Use only grounded hoses with a maxi-
mum of 500 ft (150 m) combined hose length to ensure
grounding continuity.
Air compressor: Follow the manufacturer's recommenda-
tions.
All solvent pails used when flushing: Follow the local code.
Use only grounded 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.
Air Exhaust Ventilation
Warning
TOXIC FLUID HAZARD
Read the USING HAZARDOUS FLUIDS and
FIRE AND EXPLOSION HAZARD sections
on page 3 before you operate this pump.
Be sure the system is properly ventilated for
your type of installation. You must vent the
exhaust to a safe place, away from people,
animals or food handling areas when pump-
ing flammable or hazardous fluids
If the diaphragm ruptures, the fluid being
pumped is exhausted with the air. Place a
container at the end of the air exhaust line to
catch fluid in case the diaphragm ruptures,
and disconnect the pump.
