Overview
The Tandem Heavy Duty DynaMite Supply System is
designed to provide continuous dispensing of material
by having two DynaMite 190 Extruders supplying mate
rial to the same dispensing equipment. This method
avoids having to interrupt production when replacing a
pail of material.
Only one supply pump is active at a time. The system
automatically starts the non-active supply pump when
the active supply pump is done dispensing material.
This enables the operator to replace the pail of material
for the pump that just completed dispensing while the
other pump continues to dispense material.
This process is controlled by a switch on each supply
pump that is triggered when the pump reaches its low
limit. When the system stops that pump from dispensing
and actuates the other pump, the light tower signals the
operator that it is time to replace the pail of material.

Installation
NOTE: See DynaMite 190 Extruder Instructions - Parts
manual 308302 for specific DynaMite pump installation
information, including wiper plate setup and pump com
ponents and accessories
Grounding
Pump: for both pumps, unscrew the green grounding
screw (W) and washer (X) located on the ram base (Z).
Install a 1.5 mm2(12 awg) minimum ground wire (Y)
and secure with the screw and washer. Connect the
other end of the ground wire to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check elec
trical resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommenda
tions.
Spray gun / Dispense valve: ground through connec
tion to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
System Location and Setup
NOTE: The letters in parentheses used in this descrip
tion refer to the callouts in Figure 1 on page 7.
1. Move the machine using a fork lift or pallet jack.
Insert the forks under the table’s lower shelf.
2. Place the unit on a hard, level surface. Check that
the unit is level in all directions. Refer to Dimen
sions on page 21 to ensure that there is sufficient
overhead clearance. Leave room on both sides so
the air regulators on the supply pumps will be easily
accessible.
3. Mount the table (B) to the floor using four 1/2 in. (12
mm) bolts through the table’s mounting holes (R).
4. Plug the light tower power cord (P) into a wall outlet.
5. Connect an air supply hose to the 1/4 npt air shut off
valve (K) on the main air inlet manifold (L).
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.

any air tubes on the tandem DynaMite supply system.
Connection
1. Grasp the tube, then slowly push it straight into the
fitting until it stops.
2. Be sure that the tube is securely connected, and will
not pull out when air pressure is applied. To check,
pull gently on the tube.
Disconnection
1. Follow the Pressure Relief Procedure on page 12.
2. Push evenly on the fitting’s red release button.
3. While holding the release button in, pull the tube out
of the fitting.
4. To reuse the tubing, cut off the previous connection
portion at 90°, being careful not to damage the outer
diameter of the tube.
NOTE: Use of a tube cutter is recommended. The fitting
will leak if the tubing is not cut at 90°.
Flush the System
NOTE: The pumps in the tandem supply system are
tested with lightweight oil, which is left in to protect the
pump parts. If the fluid you are using might be contami
nated by the oil, flush it out with a compatible solvent
before using the pump.
Flush with a fluid that is compatible with the fluid you are
pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for rec
ommended fluids and flushing frequency. Always flush
the pump before fluid dries on the displacement rod.
Refer to DynaMite 190 Extruder Instructions - Parts
manual 308302 for instructions on how to flush the
DynaMite 190 Extruder pumps.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest pos
sible pressure.
NOTICE
Never leave water or water-based fluid in a carbon
steel pump overnight. If you are pumping
water-based fluid, flush with water first, then with a
rust inhibitor, such as mineral spirits. Relieve pres
sure, but leave rust inhibitor in the pump to protect
parts from corrosion.
