Viking Pump H124A

SAFETY INFORMATION! IMPROPER INSTALLATION, OPERATION OR MAINTENANCE OF PUMP MAY CAUSE SERIOUS INJURY OR DEATH, AND/OR RESULT IN DAMAGE TO PUMP AND/OR OTHER EQUIPMENT. VIKING’S WARRANTY DOES NOT COVER FAILURE DUE TO IMPROPER INSTALLATION, OPERATION OR MAINTENANCE

External lubrication applied slowly with a hand gun to all lubrication fittings every 500 hours of operation with multi-purpose grease, NLGI # 2?

Contact your Viking Pump® representative with specific lubrication questions

Engineering Service Bulletin ESB-515 is located in the Appendix for standard grease thickener types used by Viking to check compatibility

Applications involving very high or low temperatures will require other types of lubrication

O-Pro™ seals greased every 500 hours of operation with a lubricating fluid compatible with the process fluid?

Warning: Carbon graphite is a brittle material and easily cracked. If cracked, the bushing will quickly disintegrate.

Is the bushing started straight?

Did you stop pressing operation until bushing is in proper position?

Check bushing for cracks after installation.

Carbon graphite bushings with extra interference fits are frequently furnished for high temperature operation.

Enter the temperature of the bracket or idler.

Did you install cool bushing with a press?

If facilities are not available to reach 750°F. temperature, it is possible to install with 450°F. temperature; however the lower the temperature the greater the possibility of cracking the bushing.

Did you consult your Viking Pump® representative with specific questions on high temperature applications?

Danger! Before opening any Viking pump liquid chamber (pumping chamber, reservoir, relief valve adjusting cap fitting, etc.) be sure:

Pressure in the chamber has been completely vented through the suction or discharge lines, or other appropriate openings or connections.

The driving means (motor, turbine, engine, etc.) has been “locked out” or made non-operational, so that it cannot be started while work is being done on pump.

You know what liquid the pump has been handling and the precautions necessary to safely handle the liquid.

Upload the material safety data sheet (MSDS) for the liquid to be sure these precautions are understood.

Failure to follow above listed precautionary measures may result in serious injury or death.

End Clearance Adjustment - After long service, the running clearance between the end of the rotor teeth and the head may have increased through wear.

This wear may cause a loss of capacity or pressure. Resetting end clearance will normally improve pump performance.

Refer to TSM on particular model series for procedure on adjusting end clearance for pump involved.

Warning: This procedure requires trained personnel with PPE!

Idler and bushing examined for wear?

Head and pin examined for wear?

Is there moderate wear on idler bushing and idler pin?

If there is moderate wear, replace the idler bushing and idler pin.

Head of the pump removed as per TSM?

Idler remained on the idler pin during head removal?

If idler slides off, it can cause personal injury or damage the part.

New packed pumps require initial packing adjustment to control leakage as packing “runs in”.

Make initial adjustments carefully and do not over -tighten packing gland.

After initial adjustment, inspection will reveal need for packing gland adjustment or packing replacement.

Contact your Viking Pump® representative for Engineering Service Bulletin ESB- 521 regarding repacking pump.

Occasional packing adjustment may be required to keep leakage to a slight weep.

If impossible to reduce leakage by gentle tightening, replace packing or use different type.

Refer to Technical Service Manual on particular model series for details on repacking.
