Introduction; Inspection; Pre-Installation Inspection - Pioneer PT Series Operation & Maintenance Manual

Thank you for purchasing a Pioneer Self-Priming centrifugal pump, complete with integral suction
check valve. The pump is designed for handling non-volatile, non-flammable, mild industrial
corrosives, residues and slurries containing large entrained solids. The standard pump is constructed
of ASTM A536 ductile iron casing with ductile iron impeller and 17-4 PH stainless steel shaft and
steel and iron wear parts.
WARNING!!!
This manual provides installation, operation and maintenance instructions for your Pioneer Self-
Prime Pump and is intended to make your personnel aware of any procedure that requires special
attention because of potential hazards to personnel or equipment. Read all instructions carefully and
remember, pump installations are seldom identical. Therefore, this manual cannot possibly provide
detailed instructions and precautions for each specific application. Thus, it is the owner/installer's
responsibility to ensure that applications not addressed in this manual are performed only after
establishing that neither operator safety nor pump integrity are compromised by the installation.
WARNING!!!
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.
Remember: Pump performance may be affected by changes in pumpage such as, specific gravity,
viscosity, temperature, operating speed and NPSHA (net positive suction head available).

PRE-INSTALLATION INSPECTION

The pump assembly was inspected and tested before shipment from the factory. Before installation,
inspect the pump for damage that may have occurred during shipment. Check as follows:
a. Inspect the pump for cracks, dents, damaged threads, and other obvious damage.
b. Check for and tighten loose attaching hardware. Since gaskets tend to shrink after drying,
check for loose hardware at mating surfaces.
c. Carefully read all warnings and cautions contained in this manual or affixed to the pump, and
perform all duties indicated. Note the direction of rotation indicated on the pump and check
that the pump shaft rotates counter-clockwise when standing on the suction side of the pump
and facing the impeller.
