Engineering Operation & Maintenance Enhance your process

TEMPERATURE LIMITS CAUTION: Mag-drive pumps are generally intended for use with fl uids with little or no particulate in the process. Excessive or large particulates in the process media will adversely affect pump performance and service life. For process media with more than 5% by volume particulates or with solids larger than 50׵ (microns), it is recommended that you use a Wilden air-operated double-diaphragm pump. For process media with 5% or less by volume particulates and with solids smaller than 50, it is recommended that you use the Sintered SiC bearing option in the Wilden pump. However,...

CONT. CAUTION: Periodically inspect the interior of the pump for damage or wear, especially when the pump is being used with a fl uid near its freezing point. In some cases the fl uid may crystallize even when the pump is only shut down for a short period. Use of an automatic drain system or heat tracing may be used to counter this process. CAUTION: The process fl uid and cleaning fl uids must be chemically compatible with all wetted components. See Chemical Compatibility Guide (E4) for details. CAUTION: Never disconnect any fl uid process lines that may contain pressurized fl uid. Be sure to...

Motor will not rotate when system is turned on. 1. Ensure that motor is connected to power supply and that supply switch is installed properly.2. Inspect motor to ensure that is it is operating condition and does not require service.3. Ensure that the power lines have been properly connected for the supply voltage and Hz.4. Ensure that no debris is lodged within the motor assembly. Flow rate is ABOVE the specifi ed fl ow for the application. 1. Confi rm the system total dynamic head conditions have not changed from the specifi ed values.2. Confi rm the process fl uid is the same temperature,...

CAUTION: Before any service is performed on a Wilden pump, all electrical lines must be disconnected and all process fl uid drained from the pump. DO NOT open the pump connections if process fl uid pressure remains inside the pump. Use the liquid end drain plug to drain remaining fl uid from the impeller chamber.

Step 6 Remove the rear casing of the liquid end from the mounting bracket. Inspect for wear inside and out, as this may be a sign of misalignment of the impeller or outer magnet. Step 5 Step 4 Carefully remove the impeller/magnet assembly. Use caution not to pinch fi ngers as the impeller will show resistance being removed due to the magnetic fi eld of the outer magnet. Remove and inspect outer casing o-ring for damage or wear. Replace as necessary. Step 9 Using a metric socket and socket extension, remove the mounting bracket fasteners by turning counterclockwise. Step 8 Once the set screw is...

Step 11 Step 10 Carfully remove the pump shaft from the front shaft support. DO NOT twist or fl ex the shaft to assist the removal. Pull vertically to free the shaft from the front support. Carfully remove the mounting bracket from the motor, exposing the shaft. > WILDEN PUMP & ENGINEERING, LLC 18 WIL-15020-E-01 size="-2">
