The vacuum pump has three cams and pistons pumping in parallel, driven by a common shaft. The cams are positioned on the shaft so as to dynamically balance moving parts. This balancing technique applied to the Rotary Piston Principle was developed by Tuthill Vacuum & Blower Systems and virtually eliminated vibration.
4.1 PRINCIPLE OF OPERATION Gas is drawn into the pump through a common inlet, channeled to the three piston slides and into the space behind the pistons as they rotate. The gas ahead of the pistons is compressed and forced out the discharge valves.
5. INSTALLATION 5.1 GENERAL KT pumps should always be operated with the pump in a vertical and level position. KT pumps should never be installed in a horizontal or angled position. Pump assembly should be placed on a foundation and should be supported evenly.
The KINNEY KT Pump is lubricated by a pressurized oil system. A positive displacement pump generates oil pressure. KT Vacuum Pumps use Tuthill KV100 oil. KV100 is used for factory testing and the initial charge is shipped along with the pump. It is necessary to utilize this oil to maximize pump life, achieve design intents and maintain full warranty.
Suction Manifolding section. Use oil recommended by Tuthill Vacuum & Blower Systems and see the specifications for the quantity of oil required to fill the pump. Remove the filler plug at the top of the separator housing and add oil until the level reaches the top of the sight gauge.
5.4 PIPING CONNECTIONS Manifolding should be no smaller than the pump connections in oder to minimize restrictions to gas flow. Accurately align the mating flanges to the inlet and discharge manifolding to prevent distortion of the pump housing. WARNING Pipe loading on the pump should be negligible as pipe loading can cause distortion of the pump.
PROPER VENTING The vacuum pump must be properly vented to ensure all oil is removed from the pumping chamber before the pump is turned off. Also, the suction line must be properly vented to ensure oil does not migrate into the process chamber.
5.4.2 HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS DANGER It shall be the responsibility of the installer to ensure that piping is adequate, sealing between pipe joints is adequate for the process fluids and proper process and pressure protection devices are in place. It is also the responsibility of the installer to assure that process gasses are not vented in a manner that would be hazardous.
Figure 5 - Water Jacket Heater Installation A water pressure relief valve is fitted in the water jacket. This relief valve is set to open at 50 PSIG (3.5 bar). Standard cooling water rates are for up to 80°F (26°C) supply temperature and operation within the design of continuous NIPPLE operating pressure range of .1 to 100 Torr (.13-130 mbar a).
Optional custom control panels and electrical accessory components, along with schematic wiring diagrams and wiring instructions are available separately from Tuthill Vacuum & Blower Systems. 6.2 PRE-START CHECKS Before starting the pump check the following items: 1.
See the Gas Ballast section. For applications where the vapor load exceeds that which can be handled by the gas ballast valve, consult Tuthill Vacuum & Blower Systems about Vapor Handling Systems, which can usually be retrofitted to existing pumps.
Sometimes a process related coating build up can be removed by soaking the pump with the proper solvent (Turning by hand) – check with Tuthill Vacuum & Blower Systems. Inspecting the inside of the pump is covered under the Disassembly section.
plugs and any penetrations into the vacuum area and check pump blank off performance before making permanent repairs with Loctite 515. If gasketed connections are suspected, remake the connections. Plastic sealing compound may be used to make temporary gaskets; these should not be made too thick since the material may be squeezed into the pump.
acetone, alcohol, freon or helium. Position the vacuum gauge head downstream from the suspected leak area, between the leak and pump. When the pressure has been reduced so that the gauge may be used , apply probing medium to suspected leak areas using a squirt gun or brush . If the probing fluid is directed at the leak or an area close to it, a sudden change in pressure will occur.
If the oil is being drained due to oil contamination, it is advisable to drain the oil from the discharge valve well. The well is between the pump cylinder and separator housing, the oil trapped there can be drained by removing the pipe plug(s) from the cylinder located above the heads.
Major repairs not covered in this book should be referred to the nearest Tuthill Vacuum & Blower Systems service representative. Pump repair services are available at our factory in Springfield, MO, our Northeast Repair Center in the Boston, MA area and our West Coast Service Center in the Los Angeles, CA area.
8. REPAIR INSTRUCTIONS 8.1 GENERAL DANGER The pump and parts may contain hazardous media as determined by the process. Assure that pump and parts are evacuated of hazardous media prior to servicing. WARNING Machine should be powered off and secured with proper Lock Out / Tag Out procedures prior to removal of any guards or panels and to ensure there are no accidental starts.
To inspect the discharge valves, proceed as follows: 1. Drain oil from the pump and remove the separator housing cover. 2. Unscrew the air/oil separator from the top of the valve deck cover. 3. Remove the capscrews from the valve deck cover and remove the cover. 4.
8.3 V-BELT DRIVE Before attempting to tension the V-belt drive it is imperative that the sheaves be properly aligned. V-belts should be replaced and the sheaves MOTOR should be positioned so as to allow the belt to be placed in the grooves without rolling them onto the sheaves.
17. Remove the retaining ring from the shaft. Loosen the socket head self-locking screws in the removable wall to release the pins securing the wall to the cylinder. Remove the wall, being careful not to cock it as it is removed. 18.

13. Place the cam keys in the shaft grooves and tap the outer cam onto the shaft with the threaded holes of the cam outward. 14. Place the open head slide-pin on the piston slide with the flat edge toward the piston and insert the piston and slidepin into the cylinder with the inlet ports of the piston facing down.
9. TROUBLESHOOTING Although Tuthill Vacuum & Blower Systems 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.
