INTRODUCTION

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 Self­Prime 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).

INSPECTION

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.

CAUTION!!!

If equipment is stored more than twelve (12) months, some of the components or lubricants may
have exceeded their maximum shelf life. These must be inspected and replaced as necessary prior to
pump operation to ensure proper pump performance.

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.

WARNING!!!

Before attempting to open or service the pump:

1. Familiarize yourself with this manual.

2. Disconnect or lock out the power source to ensure that the pump will remain inoperative.

3. Allow the pump to cool if overheated.

4. Check the temperature before opening any covers, plates or plugs.

5. Close the suction and discharge valves.

6. Vent the pump slowly and cautiously.

7. Drain the Pump.

WARNING!!!

This pump is designed to handle mild industrial corrosives, residues and slurries containing large
entrained solids. Do not attempt to pump volatile, corrosive, or flammable materials that may
damage the pump or endanger personnel as a result of pump failure.

WARNING!!!

After the pump has been positioned, make certain that the pump and all piping connections are tight,
properly supported and secure before operation. (Refer to Installation section)

DANGER!!!

Do not operate the pump without the guards in place over the rotating parts. Exposed rotating parts
can catch clothing, fingers, or tools, causing severe injury to personnel.

WARNING!!!

Do not remove plates, covers, gauges, pipe plugs, or fittings from an overheated pump. Vapor
pressure within the pump can cause parts being disengaged to be ejected with great force. Allow the
pump to cool before servicing.

WARNING!!!

Do not operate the pump against a closed discharge valve for long periods of time. If operated
against a closed discharge valve, pump components will deteriorate, and the liquid could come to a
boil, build pressure, and cause the pump casing to rupture or explode.

WARNING!!!

Remove suction and discharge piping from pump prior to moving. Use lifting and moving
equipment with adequate capacity and in good repair.

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. Never exceed the maximum permissible operating pressure
of the pump as shown on the pump performance curve.

FOUNDATION/BASE PLATE/SKID

If using a concrete foundation it should be rigid enough to inhibit vibration. Pour the foundation
well in advance of installation of pump equipment to allow time for drying and curing.

If the pump is to be mounted on a steel frame, or similar structure, it should be set directly over the
supporting beams. These beams and the structure must be rigid enough to prevent distortion and
potential misalignment due to movement within the structure or base.

The location of this structure should be as close as possible to the pumpage source. Provide
adequate space for operation, maintenance and inspection of the pump and equipment.

The concrete foundation should be provided with anchor bolts for attachment to the base plate. If
required, provide adequate drainage to keep pump and motor dry and clean. Also, provide either
leveling nuts or leveling wedges for mounting the base plate to the foundation.

LEVELING

When mounting the base plate to the foundation use the leveling nuts or wedges to provide a level,
flat base plate. Use a machinist's level on the mounting pads and make adjustments as necessary as
the anchor bolts are tightened. This will provide the true alignment between the pump and motor.

GROUT

If this base plate is to be grouted, ensure that you have the mounting surface flat and level for correct
alignment of pump and motor. Build a dam around the base plate perimeter that is to be watertight.
Use standard grouting practice and be sure to protect (cover) the leveling wedges with caulk or
plastic tape if they are to be removed later. After the grout has thoroughly hardened, remove forms.
If the wedges are removed, fill holes with grout. Seal grout by covering with a quality paint or
sealer.
