Secure a parts list from the factory or a Viking® representative.

Always give complete name of part, part number and material

with model number and serial number of the pump when

ordering repair parts.

The unmounted pump or pump unit model number and serial

CAUTION !

THE 200-G AND 260-G SERIES ARE UL

LISTED PUMPS. ANY CHANGES OR

REPAIRS TO THE PUMP WILL VOID THE UL

LISTING. TO MAINTAIN THE UL LISTING,

THE PUMP WILL NEED TO BE REPLACED

WITH A NEW PUMP OR REPAIRED AND

RETESTED AT THE FACTORY.

SPECIAL INFORMATION

DANGER !

Before opening any Viking pump liquid

chamber (pumping chamber, reservoir, relief

valve adjusting cap fitting etc.) Be sure:

1. That any pressure in the chamber has

been completely vented through the

suction or discharge lines or other

appropriate openings or connections.

2. That 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.

3. That you know what liquid the pump

has been handling and the precautions

necessary to safely handle the liquid.

Obtain a 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.

ROTATION: Viking pumps operate equally well in a clockwise or counterclockwise rotation. When rotation changes, the suction and discharge is reversed. PRESSURE RELIEF VALVES: 1. Viking pumps are positive placement pumps and must be provided with some sort of pressure protection. Series 200-G and 260-G pumps are only available with a return to tank relief valve. 2. If pump rotation is to be reversed during operation, pressure protection must be provided on both sides of pump. 3.

2. 3. Install the rotor and shaft. Place the end of the shaft in the bracket bushing or needle bearing. Turn from right to left slowly, pushing it into place, until the end of the rotor teeth are just below the face of the casing. Placing the head and idler on the casing will force the rotor to its proper depth. Be sure the shaft is free from burrs and foreign particles that might damage the bracket bushing or needle bearing. Remove the tapered sleeve from the shaft.
