SAFETY INFORMATION

!!WARNING!!WARMAN WOULD LIKE TO BRING TO YOUR ATTENTION THE POTENTIAL HAZARDCAUSED BY THE CONTINUED OPERATION OF CENTRIFUGAL PUMPS WHEN THEINTAKE AND DISCHARGE ARE BLOCKED. EXTREME HEAT IS GENERATED ANDRESULTS IN VAPORIZATION OF THE ENTRAPPED LIQUID. THIS CAN RESULT IN A LIFETHREATENING EXPLOSION.

The operation of centrifugal pumps on slurry applications can increase this potential hazarddue to the nature of the material being pumped. The additional hazard believed to be presentedby slurry applications stem from the possibility of solids blocking the pump discharge andremaining undetected. This situation has been known in some instances to lead to the intakeside of the pump also becoming blocked with solids. The continued operation of the pumpunder these circumstances can be extremely dangerous. If you have an installation that may beprone to this occurrence, we suggest you adopt measures to prevent this blockage situation

!!GENERAL WARNINGS!!

1. DO NOT OPERATE THE PUMP AT LOW OR ZERO FLOW CONDITIONS, OR UNDER ANY CIRCUMSTANCES THAT COULD CAUSE THE PUMPING LIQUID TO VAPORIZE.Slurry pumps should not be operated at flow less than 25% of the best efficiency point for agiven RPM. PERSONAL INJURY AND EQUIPMENT DAMAGE COULD RESULT.

2. The WARMAN PUMP is both a PRESSURE VESSEL and a piece of ROTATINGEQUIPMENT. All standard safety precautions for such equipment should be followed beforeand during installation, operation, and maintenance.

3. UNDER NO CIRCUMSTANCE SHOULD HEAT BE USED TO EXPAND OR CUT ANIMPELLER FROM THE SHAFT. Personal injury and damage to equipment could occur as aresult of an explosion. A shaft wrench has been provided to assist impeller removal. In somecases, a release collar has also been provided to assist impeller removal.

4. DRIVER ROTATION MUST BE CHECKED before belts or couplings are connected.Personal injury and damage to equipment could result from operating the pump in the wrong

direction. Do not touch rotating members with your hand to establish the direction of rotation.

5. For AUXILIARY EQUIPMENT (motors, belt drives, couplings, gear reducers, variable speeddrives, etc.), standard safety precautions should be followed and appropriate instructionmanuals consulted before and during installation, operation, and maintenance.

6. A PUMP SUBJECT TO VACUUM MUST BE ISOLATED during maintenance and non-pumping periods. Failure to isolate properly could allow impeller to “free-wheel”, resulting inequipment damage and personal injury.

7. DO NOT OPERATE THE PUMP without properly installed stuffing box, v-belt and couplingguards in place.





8. DO NOT OPERATE THE PUMP if solids have settled and the rotating element cannot beturned by hand.

9. Do not feed very hot liquid into a cold pump or very cold liquid into a hot pump. Thermalshock may cause damage to the internal components and rupture the pump casing.

10. Do not start a pump that is rotating in reverse, such as the backward rotation caused byslurry runback. Personal injury and damage to equipment could result.

11. Worn pump components can have sharp or jagged edges. Caution must be taken inhandling worn parts to prevent damage to slings or personal injury.

12. For the safety of operating personnel, please note that the information supplied in thismanual only applies to the fitting of genuine Warman parts and Warman recommendedbearings to Warman pumps. On larger pump models equipped with anti-rotate nuts andcover plate studs it is essential these nuts be fully installed (threaded on) by hand prior

to assembly. Personal injury and damage to equipment could result otherwise.

13. Tapped holes (for eyebolts) and lugs (for shackles) on Warman parts are for liftingindividual parts only.

14. Some equipment such as gear reducers, motors, and oil lubricated pump bearingassemblies are shipped without lubricating oil. Be certain that oil of the proper grade is filled tothe proper level in each piece of equipment before start-up.

15. Do not apply heat to or hardface Warman high chrome components. This can causecracks, residual stresses, and changes the fracture toughness of the parent material. This maylead to catastrophic failure and could result in personal injury and equipment damage evenwhen operating within recommended speed and pressure limits.
