Repair/Conversion kit numbers, page 3.
INSTALLATION
Mounting Position. Pump may be mounted
in any position. When mounting vertically, it
is necessary to keep bearings above seals
to prevent possible seal leakage into
bearings.
Pre-Wetting. Prior to connecting pump, wet
pump elements and mechanical seal by
adding fluid to be pumped into suction and
discharge ports. Turn pump over several
times
in
a
clockwise
screwdriver slot in end of motor shaft.
Piping. Piping to pump should be self-
supporting to avoid excessive strain on
pump housings; 3/8" NPT pipe for suction,
and. 1/4" NPT pipe for discharge on all metal
housing models. 5/8" ID hose with hose
clamp for suction and discharge ports of
plastic housing models. Use pipe "dope" or
tape to facilitate disassembly and to provide
seal on pipe connections.
Electrical. Follow the wiring diagram on the
motor nameplate or inside the terminal box
for the proper connections. The wiring
should be direct and conform to local
electrical codes. Check power connections
for proper voltage. Voltage variations must
not exceed ± 10% of nameplate voltage.
Motor is provided with internal automatic
overload protection.
SERVICE MANUAL

500 PUMPS
200 SERIES MOTORIZED
MODELS
To prevent damage to pump, pump rotation
must be clockwise when facing pump from
motor end.
OPERATION
Self-Priming. With wetted pumping
elements, the pump is capable of 25 feet of
suction lift with pipe size equal to port size.
Be sure suction lines are air tight or pump
will not self-prime.
DO NOT RUN DRY. Unit depends on liquid
direction
using
pumped for lubrication. For proper
lubrication, flow rate should be at least 10%
of rated capacity.
Pressure and Temperature Limits.
Maximum discharge pressure is 40 psig.
Unit is suitable for service at temperatures
shown in Table 1.
Storage. Always drain pump for extended
storage periods by removing suction
housing bolts and loosening suction
housing.
