About safety messages
It is extremely important that you read, understand, and follow the safety messages in this
manual before handling the product. They are published to help prevent these specific
hazards:
Personal accidents and health
Product damage
Product malfunction
Hazard criteria
DANGER:
A situation where a hazard, if not avoided, will result in serious bodily injury and/or death.
WARNING:
A situation where a hazard, if not avoided, could result in serious bodily injury and/or
death.
CAUTION:
A situation where a hazard, if not avoided, could result in less severe bodily injury.
NOTICE:
A potential situation, which if not avoided, could lead to product malfunctions.
Safety
WARNING:
The operator must be aware of safety precautions to prevent physical injury.
Any pressure-containing device can explode, rupture, or discharge its contents if it is over
pressurized. Take all necessary measures to avoid over-pressurization.
Operating, installing, or maintaining the unit in any way that is not intended could cause
death, serious personal injury, or damage to the equipment. This includes any
modification to the equipment or use of parts not provided by PW-IND. If there is a question
regarding the intended use of the equipment, please contact a PW-IND representative
before proceeding.
This manual clearly identifies accepted methods for disassembling units. These methods
must be followed. Trapped liquid can rapidly expand and result in a violent explosion and
injury. Never apply heat to impellers or their retaining devices to aid in their removal unless
explicitly stated in this manual.
If the pump/motor is damaged or leaking, do not operate as it may cause an electric shock,
fire, explosion, release of toxic fumes, physical harm, or environmental damage.
Correct/repair the problem prior to putting the pump back in service.
Do not change the service application without the approval of an authorized PW-IND
representative.

• a precision dowel pin fitted to the bearing frame.
Power end
• Flinger oil lubrication is standard.
• No machining is required to convert from oil to grease or oil-mist lubrication.
Regreaseable bearings and oil-mist lubrication are optional.
• The oil level is checked through a sight glass located on both sides of the
power end.
• The power end is sealed with labyrinth seals.
• The power end is made in the following sizes:
• Group 1
• Group 2
• Group 3
• Group 4

Shaft
The shaft is available with or without a sleeve.
Bearings
The Non-Drive End (INBOARD) bearing
• Carries only radial loads.
• Is free to float axially in the frame.
• Is a single-row deep-groove ball bearing
The Drive End (OUTBOARD) bearing
• Is shouldered and locked to the shaft and housing to enable it to carry radial
and thrust loads.
• Is a double-row angular-contact bearing, except for the Group 3 which uses a
pair of single-row angular-contact ball bearings mounted back-to-back.

Transportation guidelines
Pump handling
WARNING:
Make sure that the unit cannot roll or fall over and injure people or damage
property.
PW-IND pumps contain sensitive parts that can be damaged if dropped or
subjected to impact. Handle the equipment with care and do not attempt to
install or operate a pump unit that is damaged.
Lifting methods
WARNING:
All lifting must be done in compliance with all applicable regulations/standards.
Assembled units and their components are heavy. Failure to properly lift and
support this equipment can result in serious physical injury and/or equipment
damage. Lift equipment only at the specifically identified lifting points.
Crush hazard. The unit and the components can be heavy. Use proper lifting
methods and wear steel-toed shoes at all times.
Do not lift any pump or motor by attaching lifting equipment to shaft ends.
Table 1: Lifting Methods
Pump type
Lifting method
A bare pump without lifting
handles

Storage guidelines
Pump storage requirements
Storage requirements depend on the amount of time the pump unit will be stored
prior to installation and start up. The normal packaging is designed only to protect the
unit during shipping.
Table 2: Storage
Length of time in storage
Storage requirements
Upon receipt/short-term (less than six months)
• Store in a covered and dry location.
• Store the unit free from dirt and vibration.
Long-term (more than six months)
• Store in a covered and dry location.
• Store the unit free from heat, dirt, and
vibration.
• Rotate the shaft by hand several times at
least every month ensuring that the shaft
is not in the same position each time.
NOTICE:
Risk of damage to the mechanical seal or shaft sleeve on units supplied with
cartridge mechanical seals. Follow seal manufacture’s recommendations for
long term storage.
Treat bearing and machined surfaces so that they are well preserved. Refer to
motor and coupling manufacturers for their long-term storage procedures.
Long term storage preparation is available as part of initial product purchase or after
your pump has been delivered. Contact your local PW-IND sales representative.
