Page 4: Introduction
INTRODUCTION GENERAL This manual applies to KDH-130, and KDH-150 pumps built from 1974 to date. Earlier models may differ. The KDH-130 was replaced by the KDH-130B (and by the KDH-131 for radiator filling applications) in November 1987. Serial numbers between 871080 and on are the new “B” model. The differences between the KDH-130 and the KDH- 130B are: 1. -

Within each section is a piston which is driven by a cam. The cams are mounted 180 degrees apart on a single shaft so that the centrifugal forces of the moving pistons will oppose one another. The shaft passes through the center wall separating the two pump sections and is supported in bearings in the heads at each end of the cylinder. -
Page 6: Dynamically Balanced Pump
DYNAMICALLY BALANCED PUMP The term “dynamically balanced” applies to pumps which have been specifically balanced to reduce vibration. The KDH series are dynamically balanced by having each cam a different weight and adding counterweight to the pump sheave. The heavier cam is installed on the open head or drive shaft end of the pump. When reassembling a pump or ordering parts, be careful to distinguish between the heavy or open head cam and the light or closed head cam. -

1. Be sure that the suction lines are absolutely free of foreign matter and perfectly tight. Use an inlet protection screen or drop out trap on new installations or where large welded piping is employed. 2. Make sure that the pump discharge is not obstructed 3. -
Page 8: Gas Ballast
The gas ballast valve is a manual valve located on top of the pump between the suciton flange and the drive end. A pipe connects it to both ends of the pump. Oil sealed mechanical vacuum pumps can become contaminated by vapors (commonly water or solvents) which have condensed and mixed with the oil. -
Page 9: Overheating Of Coils
Coils are designed to operate with about 50°F temperature rise. Since coils are furnished to hold the valve open they should not exceed this temperature in normal operation. Hot smell or smoke calls for investigation. First check for valve not opening due to low voltage. Failure of the valve to open when energized will cause overheating. STICKING AND JAMMING Foreign matter may cause the valve to stick, jam or leak. -
Page 10: Leak Checking Techniques
Check the lowest pressure attainable when each segment is added. If the pressure is close to that obtained previously, add the next segment. If the pressure is not, leak test the last segment. When leak checking process chambers, start at the air and gas inlet valves, doors, sight ports, electrical and mechanical feed-throughs, gauge tube fittings and any other penetrations into the vacuum portion of the process equipment. -

permanent repairs with Loctite 515. If gasketed connections are suspected, remake the connections. (Plastic sealing compound may be used to make temporary gaskets; theses should not be made too thickly since the material may be squeezed into the pump.) Check carefully around the head to cylinder joints, securing bolts, oil lines, plugs, and generally any penetration into the vacuum pumping portion of the pump. -

springs into three pairs, aligning the guide tabs in each pair. 2. Slide the first pair of springs on to the lift stop with the guide tab first. That is, with the guide tab retaining groove between each spring pair so that the springs are spaced equally around the valve. 3. -
