Centrifugal Pumps are designed for specific service and may or may not be suited for any other service without loss of performance or potential damage to equipment/personnel. If there is ever any doubt about suitability for a specific purpose; contact your Pioneer Pump, Inc. representative or the factory for assistance.
RECORDING MODEL & SERIAL NUMBERS Please record the model and serial number for your Pioneer Pump in the spaces provided below. The factory will need this information when you require parts or service.
SAFETY INFORMATION These warnings apply to PT Series basic pumps. In many cases, Pioneer Pump, inc. has no control over or particular knowledge of the power source that will be used. Therefore, refer to the manual accompanying the power source before attempting to begin operation.
INSTALLATION WARNING!!! Review safety information in safety information section. This section is intended to outline general recommendations and practices required to position and arrange the pump and piping in static lift situations. If installing the unit in flooded suction applications some of the information will need to be tailored to the specific application.
INSTALLING PUMP Ensure that all foreign material has been removed from the pump before mounting. Be sure to remove all shipping protection prior to operation. NOTE: Many of the bare pumps are shipped with protective guards and coatings. SUCTION PIPING For best performance the suction piping should be at least as large as the pump flange, never smaller.
It is imperative that the PT pump inspection cover be removed prior to this rotation check! The PT series pumps use threaded shafts and impellers; if the motor is “bumped” and rotation is backward, the impeller will unscrew and be forced against the wear plate.
OPERATION Review all safety information in the safety information section. PRE-START 1) Verify that rotation is correct and that the shaft rotates freely. CAUTION see “Rotation” section above. 2) Check all piping connections for tightness. 3) Inspect all accessories and make sure they are appropriate for your installation. 4) Verify that the driver and coupling are aligned correctly and that all guards are in place.
WARNING!!! Never run the pump with the discharge valve closed for extended periods of time. Never use the suction valve to throttle the flow. Check all suction and discharge piping for leaks. If a suction strainer is installed, check the pressure drop across the strainer. If the differential in pressure exceeds five (5) PSI have the strainer cleaned.
Liquid Temperature and Overheating The maximum liquid temperature for this pump is 160º F (71º C). Do not apply it at a higher operating temperature. Overheating can occur if operated with the valves in the suction and/or discharge lines closed. Operating against closed valves could bring the liquid to a boil, build pressure, and cause the pump to rupture or explode.
CAUTION!!! When servicing this pump, use only components provided by Pioneer Pump, Inc. Any use of non-authorized parts could result in sub-standard performance, damage to equipment and possible injury to personnel. Non-authorized parts will also void the warranty.
DISASSEMBLY CONT’D Review all safety information and follow the instructions in this manual, as well as, all tags, labels and decals attached to the pump or related equipment. Under normal conditions this pump is designed to run maintenance free, because of its rugged construction, for extended periods of time.

PUMP CASE REMOVAL Use a wrench on the hex section under the seal oil reservoir to remove the reservoir and oil reservoir nipple. Remove the four nuts that secure the pump case and seal plate to the bearing housing. The pump case can now be removed from the seal plate register. CAUTION! At this point the seal plate will no longer be bolted to the bearing housing register and should be supported so that it does not fall against the shaft.
Page 16
REASSEMBLY CONT’D If bearings are to be replaced: The bearings may be heated to 250º F for ease of installation. An induction heater, electric oven or hot plate may be used to heat the bearings. A direct flame should never be used. After heating the bearings slide the bearings on the appropriate shaft end.
Page 17
SEAL INSTALLATION CONT’D Very carefully slide the seal plate over the shaft and up against the bearing housing register. This requires caution to prevent bumping the mechanical seal stationary seat against the shaft. The silicon carbide stationary seat is very brittle and will chip easily. Once the seal plate is positioned against the bearing housing register it should be secured with a bolt and nut or a c- clamp until you’re ready to install the case.
SEAL INSTALLATION CONT’D Place the shaft sleeve o-ring over the end of the shaft and up against the shaft shoulder (where the sleeve abuts). Apply a little grease or oil to the o-ring. Slide the mechanical seal / sleeve assembly over the shaft with the flanged end of the sleeve toward the end of the shaft. Slide the assembly as far as the seal spring will allow.
