  • Page 7: Installation

    INSTALLATION General Installing the Vibramounts KT pumps are supplied with vibramounts (vibrasprings on the KT-850) which enable them to run quietly and vibration free. The pump can be operated on any floor which will support its weight. The pump must be installed on the vibramounts and flexible connectors fitted in suction, discharge, water and electrical connections.

    The installation of a Kinney oil mist eliminator on the discharge is recommended for all applications, (as shown in Figure 4). Oil which collects in the eliminator should be returned to the pump. The optional oil return kit will drain allow oil to back into the separator housing when the pump is operating at low pressure or when the pump is stopped.

  • Page 12: Vacuum Gauges

    Vacuum Gauges The vacuum gauge(s) to be installed on the pump must be selected to meet the requirements of the particular pump application. Two general types of vacuum gauges are used for the testing of vacuum equipment, total pressure reading, such as thermistor or thermocouple gauges, and partial pressure reading McLeod gauges. The McLeod gauge indicates the partial pressure of permanent gasses.

  • Page 13: Starting The Pump

    F. Close the vent valve. Handling Large Quantities of Water Use of the gas ballast valve enables Kinney pumps to handle small to moderate amounts of water and other va- pors in the suction gas stream. See the Gas Ballast section below.

    Factory service is available at Tuthill Vacuum & Blower Systems Factory in Springfield, MO and at our Northeast Service Center in Canton, MA. Authorized independent centers are also available for service of your Kinney pump. Contact us at 1-800-825-6937 for the Authorized Service Center location nearest you.

  • Page 15: Changing The Oil

    The following factors may cause the pump oil to deteriorate: · Water and solvents will lower viscosity · Solid accumulation will increase viscosity and “feel gritty” · Polymerization and chemical attack on oil will increase viscosity and odor As a “Rule of Thumb” the oil should be changed if: ·...

  • Page 16: Stalling

    Stalling If the pump stalls at any time, it may be due to loose belts, lack of lubrication caused by failure of the oil circulating pump, badly contaminated oil, coating build up or foreign matter in the pump or oil line strainer (KT-500 and KT-850). If the pump cannot be turned over freely by hand after cooling, there is foreign matter in the pump and the inside of the pump must be cleaned.

    The poppet type valve has six flat, washer-like springs which press against a sealing disk. The disk fits against a seal forming a tight seal. The springs are maintained in place by a lift stop and the entire valve is held together by a capscrew.

  • Page 20: Disassembly

    DISASSEMBLY AND ASSEMBLY Disassembly The following steps are for complete disassembly of the pump, however the pump should be disassembled only to the extent necessary for servicing. Refer to the illustrations and parts list as needed. Note that the open head is the head through which the shaft extends, and closed head is the head on which the oil pump is mounted.

  • Page 21: Assembly

    CAUTION: If the inlet ports on the piston face the wrong way the piston cannot pump. 6. Carefully clean the removable wall seating shoulder. Insert the beveled ends of the dowel pins into the outside edge of the floating wall. If necessary, use vacuum grease to hold the pins in the holes. Slide the removable wall into the cylinder from the closed head side with the crescent shaped cutout in the wall oriented to fit around the slide-pin.

    Recommended Oil The oil recommended for KT Pumps in most applications is Kinney KV-100 oil. KV-100 is specially formulated to pro- vide peak lubrication even in arduous conditions, high pumping capacity at low pressures and resist rust and oxida- tion.
