INTRODUCTION CONGRATULATIONS on your purchase of a new KINNEY KC™ Two-stage, Rotary Piston Vacuum Pump from Tuthill ® Vacuum & Blower Systems. Please examine the pump for shipping damage, and if any damage is found, report it immediately to the carrier. If the blower is to be installed at a later date make sure it is stored in a clean, dry location and rotated regularly. -

KINNEY KC™ SERIES MANUAL 1807-2 ® © 2010, Tuthill Corporation DESCRIPTION GENERAL The KC series of compound high vacuum pumps covered by these instructions consist of two basic pump groups, models: • KC-5 AND KC-8 • KC-15 The pumps within each of the first two groups are identical except for the motor and v-belt drive, which are changed to give different rotational speeds. -
Page 6: Sealing And Lubrication
Other fluids may have to be used for special applications. If varnishing is a problem, high detergent oils may be used. Where low temperature starting is required, other more suitable fluid may be used. Tuthill Vacuum & Blower Systems can recommend fluids to fit most special applications. -

Page 8: Vacuum Gauges
Other types may be too hard and transmit vibration, or too soft and may exert considerable force on the pump and piping when collapsing under atmospheric pressure. Pour a small quantity of oil into the pump suction before connecting the inlet piping to ensure proper lubrication at initial start-up. -
Page 9: Prestart Checks
one-third of the required quantity of oil into the high vacuum stage of the pump. Pour the remaining quantity of oil through the threaded hole from which the oil mist eliminator was removed. Check that the fill plug and gasket are clean and in good condition. -
Page 10: Gas Ballast
GAS BALLAST Gas ballast is an operating mechanism, which is used to prevent the condensation of vapor in a vacuum pump. Vapor present in the gas being pumped can condense during the vacuum pump compression cycle and mix with the vacuum pump oil. -
Page 11: Maintenance
recommended because of the restriction to gas flow. If it is necessary to vent the pump exhaust outside, use ordinary hose of suitable diameter. Do not position the hose so that condensate can collect and cause blockage, such as in a loop or sag in the hose. -
Page 12: Stalling
Change the oil mist eliminator if: 1. Visual inspection shows the oil mist eliminator element to be blocked by foreign matter. 2. Pump back pressure as read at inlet to the oil mist eliminator (or the oil fill plug) reads over 4 to 6 PSIG (275 to 400 mbar g). -
Page 13: Troubleshooting
TROUBLESHOOTING Although KINNEY KC™ rotary piston vacuum pumps are well-designed and manufactured, problems may occur due to ® normal wear and the need for readjustment. The chart below lists symptoms that may occur along with probable causes and remedies. SYMPTOM PROBABLE CAUSE REMEDY Process equipment faulty. -
Page 14: Pump Leaks
To read the pump blank-off pressure: 1. Close off the pump inlet by means of a vacuum valve or short segment of manifolding as shown in Figure 7. 2. Connect a vacuum gauge to the pump side of the valve or manifolding. Position the gauge connection so that it will not become flooded or blocked by splashing pump oil. -
Page 15: Leak Checking Techniques
LEAK CHECKING TECHNIQUES If a leak detector is not available, use the following methods to locate leaks: 1. Cover suspected leaks with a low vapor pressure sealing compound such as Apiezon Q, Duct Seal or Plasticine®. 2. Do this while pumping on the equipment and monitoring the pressure. A sudden decrease in pressure indicates that a leak has been covered. -
Page 16: Shaft Seal
6. Check the guide rods; these should be smooth and not worn in ridges, damaged, or worn in any way that would allow the block to bind as it slides up and down. Check the valve seat in the cylinder; it should be smooth and flush with surrounding area. -
Page 17: Disassembly
DISASSEMBLY These instructions are for complete disassembly. However, the pump should be disassembled only to the extent necessary to repair it. Reference is made to the open head and closed head ends of the cylinder. The open head is the end through which the shaft extends. -
Page 18: Reassembly
Tuthill Vacuum & Blower Systems recommends a general cleaning solvent with flash point exceeding 140° F (60° C), such as solvent-140. Avoid leaving the excessive solvent on the pump parts. As the pump is reassembled, coat the cylinder and internal moving parts lightly with AX Vacuum Oil to facilitate assembly and to ensure that all parts are lubricated when the pump is first started. -
Page 19: Replacement Parts
11. Assemble the discharge valve, valve block, two valve springs, and the two guide rods on the cylinder, replacing them in the same position as they were removed. 12. Replace the cylinder cover and gasket and tighten the securing cap screws. 13. -
